Sharing the planet: Hen harrier conservation and grouse shooting

Dr Juliette Young from the Centre for Ecology & Hydrology was on Radio 4 earlier this week, being interviewed for the Shared Planet programme. This week’s episode looked at conflicts between people over wildlife and following the programme there has been a reasonable amount of online discussion of the issues raised, including a piece by former RSPB Conservation Director Mark Avery.

One of the examples discussed during the recording was the conflict in a number of areas of the British Isles between hen harrier conservation interests and land management for grouse shooting.

Dr Young’s comments in the programme built on research she and colleagues have carried out over the past ten years working on conflicts and stakeholder involvement in biodiversity conservation (e.g. Young et al., 2005, 2007, 2010; Redpath et al., 2013). The work involves speaking to a wide range of stakeholders with different perspectives on conflicts, including government advisers, scientists, conservation NGOs and land managers, including gamekeepers, who often feel portrayed by the media and other stakeholders in a negative light, despite their belief that their management can be beneficial to a variety of species.

Dr Young said, “I sincerely hope that a solution can be found to ensure the conservation of hen harriers and other protected species. Whilst I condemn illegal activities against protected species my research has examined how, why and in which contexts conflicts emerge, and aims to analyse how shared understanding and solutions can be found. My research therefore reflects a wide range of different interests and values, all of which need to be understood to navigate through complex conservation conflicts.”

Dr Young’s research has shown that conflicts can be managed effectively through dialogue among all relevant stakeholders and this can lead to shared solutions where different human activities, including conservation, co-exist in the managed landscape (see also Redpath et al., 2013, Young et al., 2010). During the Shared Planet recording she highlighted one good example where this approach has succeeded. When the Scottish government implemented a seal conservation order in 2002 this was a catalyst by which all the local groups felt affected and understood the need to make changes. This catalyst led to the Moray Firth Seal Management Plan (MFSMP) that focused on the need to balance seal and salmon conservation. A local champion emerged who brought all relevant stakeholders, and their knowledge, together, to seek a shared solution to the conflict (Young et al., 2012, 2013a and b).

Invasive alien quagga mussel arrives in UK

The invasive alien quagga mussel (Dreissena rostriformis bugensis) has arrived in the UK. The mussel was found in Wraysbury Reservoir and the Wraysbury River, a tributary of the River Colne, near Egham, Surrey.

Top threat


Earlier this year a CEH-led invasive alien species horizon scanning exercise identified the quagga mussel as the top ranking threat to the UK’s biodiversity. The study, published in Global Change Biologyconcluded that the mussel poses a high risk because it is an ecosystem engineer with the potential to disrupt the ecological function of freshwater environments.

The horizon scanning exercise was carried out by scientists from more than 20 research institutes and universities with expertise on invasive alien species. It aimed to collate a list of invasive alien species not yet established within Britain but anticipated to arrive, establish and threaten biodiversity within five years.

Other high risk species


In addition to the quagga mussel the exercise identified a further 29 high risk species, including the Sacred ibis, the Brush clawed shore crab, the Asian hornet, and the American water-milfoil. Since the paper was published, the first UK record of the non-native Asian shore crab (Hemigrapsus sanguineus), which was included in the top 10 potential threats, has been received.

How to record sightings


An alert system operates within the UK for invasive species. The latest species alerts can be found here. If you see the quagga mussel or any other invasive alien species of concern, please report your sighting via iRecord: http://www.brc.ac.uk/irecord/enter-non-native-records

More information


The horizon scanning exercise was published in the scientific journal Global Change Biology. The paper is open access.

The Biological Records Centre is 50 years old!

This year the Biological Records Centre (BRC), based within the Centre for Ecology & Hydrology, celebrates its 50th anniversary. A celebratory symposium is being held in Bath this week, and birthday cake will be eaten by past and present staff members, as well as a wide range of people who have been associated with BRC over the last five decades.




It's a good time to look back at why the Biological Records Centre came into existence, and why it is still relevant today.

A rich history of biological recording

In the late 17th century the Catalogus Plantarum Angliae was published. Written by Essex
naturalist John Ray, it was effectively the first catalogue of English plants, drawing on observations from his friends. By the 18th century natural history societies had begun to form across the country which focused on species identification and documenting their distribution. These societies attracted a wide range of members ranging from the self-educated to the academically qualified, a mix that continues to this day.

Plants and data processing 

During the first half of the 20th century there were several attempts at creating a national overview of British species, particularly for plants. Plans for a national plant atlas were published in 1940 but delayed by World War Two. Post-war, both the British Association (in 1947) and the Botanical Society of the British Isles conference (in 1950) resolved to map British (and Irish) species and finally, in 1954, the BSBI’s Atlas of the British Flora project was launched with funding from the Nuffield Foundation, and later from the then recently established Nature Conservancy,

Former head of BRC Paul Harding commented recently:
“The atlas (of the British Flora) aimed to record, and map, each species of vascular plant in the 10km squares of the Ordnance Survey National Grid. Perhaps the most critical aspect of the project was the adoption of data processing equipment using punched cards. This enabled 1.5 million records to be sorted and mapped mechanically and the use of information technology became integral to biological recording.”
An international impact on biological recording

Building on the Plant atlas and the mapping skills developed, the Biological Records Centre was established at Monks Wood, Cambridgeshire in 1964, with Franklyn Perring as its head. Over the years BRC has grown, and moved (to Wallingford, Oxfordshire in 2008), and its work has had, and continues to have, an international impact on biological recording.

Professor William Sutherland, the Miriam Rothschild Professor of Conservation Biology at the University of Cambridge recently wrote:

“The BRC has been central to much of UK conservation practice and research. The work on climate change impacts on distribution patterns is especially well known. The detailed distribution information means the BRC is central to much of the routine conservation practice in determining priorities and assessing possible threats. The BRC has also been fundamental to the National Biodiversity Network Gateway, an ambitious plan to bring together the main sources of UK biodiversity information.”

Current priorities

Looking forward, Dr David Roy, the current head of BRC, told me that current BRC priorities include:

  • Maintaining existing capacity for recording species across a broad range of taxonomic groups to provide the evidence needed to tackle ongoing environmental issues.
  • Sustaining partnerships with expert naturalists to help this capacity to grow and adapt, thus increasing the value of biological recording for understanding environmental change.
  • Making innovative use of technology and analytical methods, plus integration with other data sources on the ecology of species and the physical environment to enhance the value of recording data.

Happy Birthday BRC. We look forward to your 100th anniversary celebration in 2064!

Dealing with invasive non-native species - new EAC report

Updated 16 April

The Environmental Audit Committee (a UK Commons Select Committee) report on invasive non-native species was published this morning and has been widely reported within the UK media including BBC Online, the Guardian and the Daily Mail.

In response to publication Dr Helen Roy of the Centre for Ecology & Hydrology said, "It is critical that we increase our understanding of the threat to biodiversity posed by invasive non-native species. People can play a major part through surveillance by reporting sightings of concern to the GB Non-Native Species Information Portal."

Current species alerts include Asian hornet, Killer shrimps and Quagga mussel. More information on the GB Non-Native Species Information Portal hosted by the Non-Native Species Secretariat.

Professor James Bullock of CEH leads an EU wide project on on invasive ragweed. Common ragweed is an alien species which is highly invasive across Europe and has harmful impacts on a range of sectors, especially human health and agriculture. A recent report on the project can be downloaded here (large >20mb pdf).

Original post

Tomorrow morning, Wednesday 16 April, the Environmental Audit Committee (a UK Commons Select Committee) will publish a report on invasive non-native species. The report concludes an inquiry by the Committee that examines the government's policy on invasive species and the implications of the European Commission's draft EU Directive on "the prevention and management of the introduction and spread of invasive alien species".

Dr Helen Roy from the Centre for Ecology & Hydrology (CEH) gave oral evidence to the committee on 22 January 2014. Dr Roy's research covers the dynamics of invasive non-native species and their effects on native biodiversity. She chairs the COST Action ALIEN Challenge project which involves 27 countries in work to ensure a fair exchange of high quality and reliable data and information on invasive non-native species. She also leads a project to produce a comprehensive information portal on non-native species in Great Britain and manages updates to the DAISIE (Delivering Alien Invasive Species Inventories for Europe) database. Dr Roy has previously blogged on invasive species research for us (Invasive Alien Species: From Data to Decisions) and Planet Earth Online (Aliens descend on Britain).

The Report will be available on the Committee’s website from 00.01 am approximately, on Wednesday 16 April 2014.

Sustainable Land Management Science Area at CEH

CEH's new Science Strategy identifies three interdependent, major societal and environmental challenges: Securing the Value of Nature, Building Resilience to Environmental Hazards, and Managing Environmental Change. We're delivering our strategy by Science Areas and underpinning activities, and over the next few weeks we are profiling these on our blog. 

This post focuses on our Sustainable Land Management science area, which is led by Dr Richard Pywell. The research we undertake in this area is delivered in the context of ensuring adequate provision of food, fuel and water while conserving biodiversity and vital ecosystem functions.

CEH develops practical solutions to restore and enhance ecosystem
functions that deliver goods and services crucial for human wellbeing,
such as pollination services for crops and biodiversity.


Population increase, climate change, pollution and other environmental stresses are expected to have highly detrimental impacts on ecosystems and natural resources vital for human wellbeing and livelihoods. Therefore novel land management approaches to optimise natural resources are needed.




CEH's sustainable land management science area aims to understand the threats to semi-natural and highly managed ecosystems, and their component resources. From this understanding, we will develop robust strategies to conserve vital resources and increase their resilience to environmental change. We will also develop practical approaches that can be applied at the field, farm and landscape scale to restore and enhance the ecosystem functions and services crucial for human wellbeing and livelihoods.

Our research activity involves experiments, long-term monitoring, the development of practical land management and restoration techniques, engagement with practitioners and industry and the support of policy development.


Our science helps to protect, restore and enhance ecosystem functions that support food production, such as pollination and pest control.



We also engage with practitioners and the farming industry to develop new, innovative eco-intensive farming systems that are practical and commercially viable.


Future objectives include constructing spatial decision-support tools to balance demands on limited land; developing and testing management and restoration strategies; mapping potential deficits and vulnerabilities of pollination and pest control services to environmental stress; and supporting future land management policies that meet the challenges of sustainable intensification and multi-functional land use.

For more details of these and other objectives in our Sustainable Land Management Science Area, see our Science Area Summary [PDF].

Soil Science Area at CEH

CEH's new Science Strategy identifies three interdependent, major societal and environmental challenges: Securing the Value of Nature, Building Resilience to Environmental Hazards, and Managing Environmental Change. We're delivering our strategy by Science Areas and underpinning activities, and over the next few weeks we are profiling each of these on our blog.

This post focuses on our Soil Science Area, which is led by Professor Bridget Emmett. Sound scientific knowledge of soil functioning is essential to assure UK and global security for food, fuel and water.


The multidisciplinary research at CEH makes us ideally placed to develop new understanding of soil function and the relative importance of soil biota, physical and chemical properties and their emergent properties across scales. We apply this knowledge for improved sustainable management of soil and the ecosystem services soils provide.

Soils are critical for life. As well as providing nutrients and water to grow food, they help regulate floods and droughts, they play an important role in modulating the greenhouse gases which control our climate, and they support a large and diverse biological community.


But such societal benefits depend crucially on soil quantity and condition, both of which are at risk from threats such as over-exploitation, contamination and climate change. Understanding and managing the diverse and sometimes conflicting services provided by soils demands an integrated, multidisciplinary approach.
CEH's soil science expertise is multidisciplinary and allows us to develop new
understanding across scales.


CEH's current and future research objectives include new tools and data, for example we are developing in partnership a UK Soils Observatory and an enhanced mySoil app. We are aiming to increase understanding, for example of the links between biological and physical structure of upland soils and their implications for water and carbon services. We will quantify the impacts of land use change to energy crops on soil carbon stocks and greenhouse gas emissions for the UK, and we are developing web interfaces with partners to deliver real-time soil sensor data.



For more details of these and other research objectives in our Soil Science Area, please see our Science Area Summary [PDF].

Natural Capital science at CEH

We're delivering our new Science Strategy (2014-19) through a number of Science Areas and underpinning activities. Find out more about each area as we profile them over the coming weeks in a series of blog posts.

This post focuses on our Natural Capital Science Area, headed by Professor Mike Acreman.


Soil, insect pollination, water, food, nutrient cycling, flood control etc - we rely on goods and services provided by the natural environment. The concept of natural capital as the stock of environmental assets will inform decisions on how we use our natural resources and manage the environment sustainably.

Wetlands, such as this blanket bog on the Isle of Harris, provide essential ecosystem
functions and services, including regulation of water quality, sustainable control and
mitigation of flooding, greenhouse gas reduction, essential habitats for plants and
animals, and cultural and recreational facilities.

CEH carries out a wide range of research into wetlands in the UK and overseas.



CEH has unrivalled and longstanding expertise in the science of the natural environment that underpins natural capital. We'll use surveys, experiments, analysis and modelling to produce detailed knowledge of water, soils, plants, animals and atmosphere provided by the UK environment.


Research objectives in this Science Area include assessing the extent, quality, trends and vulnerability of the UK's natural capital. We also define ecosystem services that flow from the natural and managed environment, quantifying short and long-term trends and natural variations.


We'll also work with other experts in economics, health and sociology, to evaluate the benefits of natural capital to human well-being, how to balance exploitation with protection and where to target management and restoration efforts. For example, we are a partner member of the Natural Capital Initiative.


Long-term monitoring helps us record how natural capital is changing and identify the causes of change. For example, CEH coordinates the UK Environmental Change Network, and operates the UK Butterfly Monitoring Scheme in partnership with Butterfly Conservation and the Joint Nature Conservation Committee.

Ecological processes and resilience - science area at CEH

We're delivering our Science Strategy (2014-2019) through a number of Science Areas and underpinning activities. Find out more about each area as we profile them over the coming weeks in a series of blog posts. 

This post focuses on our Ecological Processes & Resilience science area, which is headed by Dr Allan Watt. Understanding of ecological processes, particularly those that affect the resilience of species, is needed to maintain ecosystems and the delivery of ecosystem services.

The benefits that flow from biodiversity and ecosystem services are increasingly under threat from environmental change. Threats include habitat loss and fragmentation, climate change and over-exploitation of natural resources. The threats are exacerbated by pests, diseases, alien invasive species and other drivers of global environmental change.


In our research we combine long-term datasets and use citizen science, models and experimental systems to examine the impacts of single and multiple drivers, including socio-economic drivers, on populations, species and ecosystems.


Other research objectives include assessing strategies to adapt to climate change in forestry, assessing lake restoration techniques, quantifying links between biodiversity and resilience to invasion by pests across a range of ecosystems, and linking time-series data from different trophic levels to assess the degree of synchrony of species interactions.


Long-term monitoring activities that help us in this Science Area include the Isle of May Study,  the UK Butterfly Monitoring Scheme and Loch Leven surveillance.

UK Butterfly monitoring – explaining the schemes and surveys

There’s been lots of coverage today of a new set of data on UK butterfly numbers. You may have seen headlines such as “Farmland butterflies bounce” back and “British farmland butterflies bounce back after 2013 summer, survey finds”.

The reports are based on a new release of data which was collected in 2013 as part of the Wider Countryside Butterfly Survey (WCBS).

The WCBS is run by Butterfly Conservation, the British Trust for Ornithology (BTO) and The Centre for Ecology & Hydrology (CEH).

As today’s press release from Butterfly Conservation states The annual survey (WCBS), running since 2009, counts butterflies in more than 850 randomly selected 1km-squares across England, Wales, Scotland and Northern Ireland to assess the health of butterfly populations across the wider countryside rather than at specially managed hotspots such as nature reserves.”

WCBS is part of the United Kingdom Butterfly Monitoring scheme (UKBMS), which has been running since 1976, and has a remit to monitors changes in the abundance of butterflies throughout the United Kingdom since 1976. Regular readers of this blog will already know how UKBMS data contributes to some of the biodiversity indicators which inform UK environmental policy making.

For those confused by the multiple butterfly surveys and schemes operated in the UK the following details may help.

  • Wider Countryside Butterfly Survey, running since 2009, aims to more effectively monitor the changing abundance of widespread butterfly species across the general countryside.
  • United Kingdom Butterfly Monitoring scheme, running since 1976, is very effective at monitoring habitat specialist butterflies and lowland semi-natural habitats.

According to the UKBMS website, in the 37 years the scheme has operated, "Recorders have made around a quarter of a million weekly visits to more than 1,500 separate sites, walking over half a million kilometres and counting over 16.4 million butterflies! 

The UKBMS 2013 results should be out in a few weeks time. The 2012 results were published on 26 March 2013.

All the butterfly surveys, as well as the majority of wildlife recording in the UK, principally rely on the efforts of volunteers so I’ll leave the last word to Kate Risely. Kate co-ordinates the Breeding Bird Survey butterfly surveyors at the BTO. She commented earlier, "These results demonstrate the value of large scale volunteer surveys for monitoring country-wide trends in butterfly numbers. Recording butterflies and birds at the same sites gives us a unique insight into the health of our countryside.”

CEH research shows ammonia emissions affect sensitive habitats upwind of a poultry farm

CEH recently led a study that found that ammonia emissions from an intensive poultry unit were detected nearly three kilometres upwind, deep within a Natura 2000 site, Newborough Warren, an important sand dune system in Wales. The research was highlighted by the European news alert service Science for Environment Policy, as well as industry website The Poultry Site.

The paper by Dr Laurence Jones describes the findings, which have major implications for the way we consider the control of emissions from intensive animal production units.

Laurence continues:

“While the majority of ammonia is transported downwind, this study suggests that ammonia emissions could be a significant source of nitrogen pollution to sensitive sites even upwind from the source.

Mobile sand dunes, a highly biodiverse habitat



Ammonia caused exceedance of UNECE nitrogen thresholds within the nearby Natura site and experiments showed that dune plant species were being affected by the nitrogen. The paper has already convinced the Environment Agency to consider effects of local wind direction and more recent meteorological data in casework.

Ammonia emissions were monitored around the farm and up to 2.8 km upwind of the prevailing wind direction for a year.

At the furthest sampling point upwind, levels of ammonia concentrations rose and fell in cycles coinciding with emissions from the farm in all months, although were much lower (averaging 0.9 μg/m3, compared with 60.1 μg/m,3 at the farm itself).

The Natura site, Newborough Warren, is one of Wales’ largest sand dune systems and is designated for a wide range of Biodiversity Action Plan priority habitats and rare species. Within parts of the site, ammonia from the farm caused exceedance of the critical level for ammonia of 1 μg/m3, and exceedance of the critical load of 8 – 15 kg N/ha/yr for sand dune grasslands. The farm contributed an additional 50% to the background levels of nitrogen deposition in parts of the site.

Common Centaury, Centaurium erythraea, a low growing biennial
often found on sand dunes


Experiments in the study showed that plants take up the ammonia as a nutrient source, and nitrogen-loving grasses and other species grew better when exposed to the ammonia than other dune species.

The study was funded by Countryside Council for Wales (now Natural Resources Wales). It confirms other CEH studies which highlight that sand dune habitats are sensitive to excess nitrogen pollution from atmospheric deposition and in groundwater.”

Construction, biodiversity and natural capital: discussing the challenges

Our latest guest blog is from Business Development Manager Dr Joanne Chamberlain on a recent first meeting between CEH and a construction industry group looking to address some of the environmental challenges their sector faces:

Last week, on 10 December, CEH hosted a visit from the UK Constructors Group (UKCG) for Biodiversity. UKCG is the primary trade association for contractors operating in the UK, and represents more than 30 leading contractors operating in the UK on construction specific issues. Between them, UKCG members account for £33 billion of construction turnover, a third of UK construction total output involving projects building hospitals, schools, offices and housing, as well as large infrastructure projects. UKCG has an Environment working group with an expert task force on Biodiversity, whose aim is to represent the views of contractors within government, promote best practice, and mitigate regulatory and legislative risk.

The UKCG for Biodiversity met with scientists at CEH to open up a discussion and assess the potential for collaboration around topics that included natural capital, ecological survey data and biodiversity offsetting. The construction industry has a number of challenges in these areas, and the group are keen to work with CEH in solving some of these problems. The UKCG aims to ensure a net gain in biodiversity in the work they undertake and enhance connectivity between developments and the wider landscape.

The construction industry has challenges in areas such as natural capital,  ecological
survey data and biodiversity offsetting.
It was interesting to note that UKCG members often find themselves in a position of having to try to influence, engage and educate their clients on how to incorporate biodiversity into a development. This inevitably results in a number of challenges and compromises, but a desire to have a consistent approach across the industry and demonstrate the merits of conserving and enhancing natural capital within a development is driving the group.

Aiming for just enough Nitrogen (and not too much!)

Professor Mark Sutton from CEH is currently in Kampala, Uganda at the 6th International Nitrogen Conference, where he has joined other scientists, agriculturalists, environmentalists, industrialists, economists and policy-makers to discuss issues linked to nitrogen management, including food security, human health, agriculture and the water cycle. On Friday (22 November), it is planned that the Conference will finalize and announce the Kampala Declaration on global nitrogen management.

Prof Sutton chairs the International Nitrogen Initiative (INI) which has organised the conference with the African Nitrogen Centre, International Institute of Tropical Agriculture (IITA) and Makerere University College of Agricultural and Environmental Sciences. Also attending the conference are Prof Sutton's CEH colleagues Prof Nancy Dise and Dr Ute Skiba, each of whom are speaking at the event.

The conference, which runs from 18-22 November 2013, has the tagline "Let us aim for Just Enough N: Perspectives on how to get there for 'too much' and 'too little' regions".

Prof Sutton is chairing a session on Global and Regional Assessment and making a keynote speech "Global Nitrogen Assessment: From Our Nutrient World to the International Nitrogen Management System (INMS)". Our Nutrient World is the UNEP publication edited by Prof Sutton which was published by CEH earlier this year. It is planned that Prof Sutton will also moderate the finalization of the Kampala Declaration on Friday.

The Kampala meeting is believed to be the world's first 'Nitrogen Neutral' conference, where delegates are offered the opportunity to contribute offsetting their nitrogen footprint associated with the conference.  At the same time, the delegates have adopted a demitarian approach - reducing their consumption of meat by half compared with the usual menu at the conference venue, the Speke Resort Hotel - as a means of reducing their own nitrogen footprint.

A key issue being discussed at the meeting is how to get more Nitrogen into Africa, with the main debate being that of fertiliser usage versus biological nitrogen fixation, and how to get the best from both aspects.

This is the sixth international conference to take place after previous events in the Netherlands, USA, China, Brazil and India. The common objective of these conferences is the design of more productive, economic and sustainable food and energy production systems to meet the challenges of the growing global population whilst minimising the cascade of environmental effects posed by nitrogen. Air pollution, water pollution, biodiversity and climate change are all impacted through "too much" nitrogen in the environment, but it is an essential part of the story to ensuring global good security.

Carbon and plant biodiversity recovery

A very short post to draw attention to new research by one of our PhD students Phil Martin (with Bournemouth University) who this week was lead author of a paper published in the Royal Society's flagship biological sciences journal, Proceedings B.

The Centre for Ecology & Hydrology published a news story about the research: Carbon storage recovers more quickly than plant biodiversity in re-growing tropical forests

You can read the paper itself on the Proceedings B website (free to access until 30 November as part of the Royal Society's commitment to Open Access Week): Carbon pools recover more quickly than plant biodiversity in tropical secondary forests

On Phil's blog Ecology for a Crowded Planet, he has written an engaging and informative post giving more details about the research and why it is important: How long does tropical forest take to recover from agricultural clearance?

The Harlequin ladybird, Harmonia axyridis: time for global collaboration

International cooperation is very important in preventing and controlling the spread of invasive species globally, as Helen Roy and Peter Brown of the UK Ladybird Survey explain in a guest blog:

It is almost ten years since the Harlequin ladybird, Harmonia axyridis, was first recorded in the UK. This invasive alien species is native to Asia and so it is particularly poignant for us to have been invited to speak at the International Congress on Biological Invasions hosted at Qingdao*, China.

We're taking part in a session entitled "Harmonia axyridis: time for global collaboration" and feel privileged to be here representing the UK Ladybird Survey, alongside the Centre for Ecology & Hydrology and Anglia Ruskin University. During our time in China we are presenting research spanning predator-prey and natural enemy interactions through to host plant and habitat associations. All possible because of the records collated by the UK Ladybird Survey.

The online UK Ladybird Survey (including the Harlequin Ladybird Survey) was launched in 2005 following the arrival of the harlequin ladybird in the UK. We could not have imagined the response - tens of thousands of people from across the UK have contributed records of the harlequin ladybird and native species of ladybird. These observations have been invaluable in providing a unique insight into the ecology of this invader and the effects it is having on native species.

The threat posed by invasive alien species is widely recognised and the harlequin ladybird provides a model system for exploring invasion biology making the data collected through the UK Ladybird Survey extremely valuable . The success of the online survey has also provided the inspiration for the development of a system for reporting many other alien species in Britain. 

One aim of our visit to China is to strengthen collaborations with researchers from around the world, and in particular to forge links with scientists working here. We hope to build on our understanding of how the ecology of the harlequin ladybird differs in its native and invaded ranges.

The harlequin ladybird is a dominant species in China as it is within the invaded range. Today we had the opportunity to observe, with excitement, the harlequin ladybird on the seafront trees of Qingdao. It was a fitting conclusion to a very productive and worthwhile trip.

Biodiversity indicators and the Biological Records Centre

The 2013 update to the UK Biodiversity Indicators has just been published on the JNCC website.
 
CEH scientists working within the Biological Records Centre contribute to several of the indicators, building on our wealth of knowledge and links to most of the UK's wildlife recording schemes. In particular, for 2013, our scientists have contributed to development of the new index on the status of priority species (C4a).

Dr Nick Isaac of CEH explains more:

"The new indicator C4a uses data from national surveys, such as the UK Butterfly Monitoring Scheme. The index provides an annual summary of the abundance of 210 mammal, bird, butterfly and moth species, all of which have been identified as priorities for the four national conservation agencies. This property makes this index much more sensitive than the old C4, in which species were categorised as declining, stable or increasing based on expert opinion."

"In addition, we also produced a supplementary index based on distribution data. These 'biological records' are not collected in a standardised way, which makes the data extremely noisy and liable to produce biased estimates of species trends. Within the Biological Records Centre, we've invested heavily in trying to understand this bias, and to extract a meaningful signal of change from the noise in the data. This investment has now paid off, because we're now able to report on the status of  taxonomic groups, such as bees, that lack standardised monitoring schemes."

"Both the abundance and distribution-based indicators show a decline of 50-60% since 1970, reinforcing the message that conservation agencies have their work cut out to prevent more species from going extinct."

More details of the C4a indicator can be found in the technical report, "Status of threatened species - status of priority species".

Other UK biodiversity indicators with CEH involvement include:

  • C6. Insects of the wider countryside (butterflies) population (data from CEH's joint stewardship of the UK Butterfly Monitoring Scheme with Butterfly Conservation)
  • C2. Habitat Connectivity (Countryside Survey data)
  • B6. Pressure from Invasive species (reflecting our work with the National Biodiversity Network)
  • B5. Pressure from Pollution
  • C7. Plants of the wider countryside (data from CEH's Countryside Survey)

CEH science also played a key role in the 2011 National Ecosystem Assessment, which is the basis of Indicator D2. Biodiversity and ecosystem services (terrestrial).

Biodiversity offsetting: the science behind the policy

The Government's Ecosystems Markets Task Force has put biodiversity offsetting amongst its top five priorities, saying that "it is about regulation, developing a well-defined market which delivers 'net gain' for nature". Dr Bruce Howard, who specialises in Biodiversity Offsetting at the Centre for Ecology & Hydrology (CEH), explains how CEH provides the independent and impartial scientific advice needed by this increasingly important policy measure.

Biodiversity offsetting is the term used for agreements that compensate, in measurable ways, for the losses to habitats and species that result from developments such as housing, railways and airports. It is being used or trialled in more than 20 countries worldwide. There is growing interest in the use of biodiversity offsets in the UK, especially in England. A voluntary approach to biodiversity offsetting was a commitment in the Natural Choice the Government's environment White Paper published in 2011. In response, here at CEH we are gearing up to ensure that our data and expertise in monitoring and restoring biodiversity play their part in informing decisions about the greater use of offsetting in the UK.

New office development




In its 2010 report on financing nature conservation, the RSPB's economists expressed similar aspirations when they said that a "strong biodiversity offset market has the potential to reduce environmental damage from development, simplify the planning system and increase funding for conservation". Nonetheless, the debate about how offsets might impact on the level of protection that the planning system provides for biodiversity is only just getting going. In a response to a 2011 Government consultation on biodiversity offsets, Wildlife and Countryside Link, a large coalition of conservation organisations, warned that "a poorly implemented offset system could have a negative effect on biodiversity."

Given all the points of view expressed, the independent and impartial scientific analysis by organisations such as CEH should play an increasingly important role. In July 2013, I was awarded a Natural Environment Research Council (NERC) Knowledge Exchange Fellowship on biodiversity offsetting. Over the coming three years, I will be drawing together expertise from across NERC and beyond to address specific questions important for offset implmentation. These include:

  • Most nature conservationists are behind the goal of reversing trends in biodiversity decline, aiming for no overall loss of biodiversity in a particular area, or the country as a whole. Advocates of biodiversity offsetting are motivated by this too. But what role will offsets play in achieving this? The jury will be out for some time yet.
  • How can individual species be safeguarded within offset agreements based on habitat? It is not as easy as one might think to establish a population of anything, from adders to yellowhammers, even if an offset site is created and managed by the very best experts.

Working alongside me, Dr Lisa Norton is piloting decision support tools that could be used to inform decisions about how and where to initiate biodiversity offsets. And from September 2013, CEH's Dr Tom Oliver will be developing an indicator of the 'ecological status' of parcels of land. This will consider species that are not on the Government's priority list of species and could help to inform choices about where biodiversity offsets can occur. CEH also has much experience in the area of how the biodiversity value of land can be improved this is an important requirement for offset creation.

As the UK's Centre of Excellence for integrated research in terrestrial and freshwater ecosystems, CEH has a unique mix of datasets capable of informing the design and monitoring of offset schemes. For example, our Countryside Survey, which is due to be updated in the next three years, provides the most comprehensive record of the condition of the British countryside. The Biological Records Centre, hosted by us at CEH, holds 27 million records to provide information on the status of and change in UK biodiversity.

Town and countryside



If implementation of offsets is to deliver benefits for biodiversity in many years to come, scientific rigour will be required at every stage. This extends from the methods used to assess the biodiversity present at individual sites proposed for development, through to monitoring the long-term contribution that hundreds of 'offset' sites are making to our national biodiversity asset. After all, biodiversity is just part of a wider suite of ecosystem services which provide everyone in society with valuable natural capital a resource whose importance is recognised, including by Government.

While the scientific rigour has its place, it should not be forgotten that nature down the street (and over the horizon) matters greatly to people. This is something that is recognised in many aspects of our work at CEH, such as our involvement in citizen science. It appears to me that there is a need to ensure that offset schemes will safeguard biodiversity (and the 'services' it provides) for people, rather than simply for the sake of meeting targets or advancing a new way of financing nature conservation.
