Summary of the impact
European Union (EU) law stipulates that governments must conserve listed
species of conservation concern, necessitating the legal designation of
Special Protection Areas (SPA) and the design and implementation of
appropriate land management and other targeted conservation policies. Such
policies should be underpinned by robust scientific understanding of
population ecology, but this is rarely achieved for populations of
immediate conservation concern.
A University of Aberdeen study of Scotland's remaining red-billed chough
bird population provided the scientific understanding and evidence
required to designate a new SPA, introduce new components to the Scottish
government's agri-environment policy and underpin emergency management
intervention.
The research thereby impacted statutory land designation and
agricultural policy, and hence the management and conservation of a
figurehead natural population in Scotland.
Underpinning research
Effective conservation management requires clear understanding of
ecological and demographic constraints on population growth. Such
understanding is typically lacking for populations of immediate
conservation concern. This knowledge gap severely limits the degree to
which conservation policy can be evidence-based, limiting the efficacy of
policy and resource allocation decisions.
The red-billed chough (Pyrrhocorax pyrrhocorax) is a rare crow
that is listed on Annex 1 of the EU Wild Birds Directive and is a
figurehead species for High Nature Value agriculture. Scottish Natural
Heritage (SNH), as the designated Scottish government agency, is legally
obliged to implement appropriate conservation policy, including
designating SPAs, agri-environment schemes and targeted management
interventions. However, SNH's ability to fulfil these obligations was
limited by a lack of rigorous scientific understanding of chough
population ecology.
Since 2001, Dr Jane Reid, a Senior Research Fellow at the University of
Aberdeen, has compiled demographic data from Scotland's main remaining
chough population on Islay [1-3]. She used these data to identify
demographic and ecological constraints that limit population growth [1-6].
While at the University of Aberdeen since 2006, she identified key
life-history stages and locations where conservation management should
focus [4-6], and translated these research results into Scottish
government conservation policy (see section 4).
Reid used sophisticated demographic analyses to show that population
growth is constrained by low juvenile survival [3,6] and that juvenile and
adult survival vary substantially among choughs fledged in different areas
of Islay [4]. This research caused policy-makers to focus on juvenile
survival, rather than on breeding adults as they had previously. It also
highlighted areas of Islay that are key to population growth [4], thereby
altering the spatial focus of conservation action. Thanks to Reid's
analysis, one key area was subsequently designated an SPA. Reid's analyses
also helped define areas that have now been incorporated into
agri-environment policy (see below and section 4).
Reid and her collaborators secured a Knowledge Transfer grant from the
Natural Environment Research Council (2006-2009, [7]) to identify
ecological causes of demographic variation and translate this knowledge
into agri-environment policy. The grant also involved Glasgow University,
SNH and the Royal Society for the Protection of Birds (RSPB), and Reid led
the work. It supported a postdoctoral researcher to collect field data,
plus data analyses and knowledge transfer among researchers, conservation
managers, farmers and birdwatchers (section 4). This research identified
ecological determinants of variation in juvenile survival [5], resulting
in land management recommendations that were subsequently implemented
through the Scotland Rural Development Programme (SRDP) agri-environment
policy (section 4).
However, substantial time elapsed before SRDP policy could be
implemented, due to the need to negotiate overarching EU policy.
Meanwhile, chough juvenile survival decreased drastically, threatening
population persistence and necessitating urgent action. Reid therefore ran
further demographic analyses to identify the precise timing of mortality
and hence the most effective times for targeted intervention [6]. Reid
tabled this information to SNH and led discussions that initiated
emergency supplementary feeding [8]. This programme is proving successful,
and SNH have now funded three further years of feeding and analysis of
future policy implications [9].
Initial data compilation and analysis was instigated during 2001-2005
while Reid was a postdoctoral researcher at Universities of Glasgow (2001,
[10]), British Columbia (2001-2003) and Cambridge (2003-2005). However
Reid undertook the main policy-relevant research, and ensured its
translation into impact, while holding a Royal Society University Research
Fellowship at the University of Aberdeen during 2006-2013 [11].

Details of the impact
Reid's research directly impacted upon government conservation and
agricultural policy regarding the conservation of an important protected
population of red-billed choughs in Scotland, and consequently impacted
conservation policy-makers and practitioners and farmers.
Reid's analyses identified specific areas of the Scottish island of Islay
that contribute substantially to chough population growth rate and hence
to maintaining a viable population of this Annex 1 species [4]. Her
analyses were used to designate a major SPA on Islay (Gruinart Flats,
total area 3261 ha [a]) with chough as a `qualifying interest'. Reid's
work [6] has subsequently supported a statutory condition assessment of
Scottish chough SPAs, causing some to be deemed in `Unfavourable'
condition relative to stipulated baselines [b]. This is now prompting
further monitoring and action by governmental and non-governmental
organisations.
Reid's research provided the rigorous understanding of demographic and
ecological constraints on chough population growth rate that was required
to write chough-specific management options into the Scottish
agri-environment scheme (the Scotland Rural Development Programme, SRDP
[4-6]). Farmers in specific areas of Islay that were highlighted by the
research can now apply for agri- environment funding to undertake land
management activities that benefit choughs [c]. These activities include
bespoke grazing and cutting regimes, and providing or maintaining chough
nest sites, in key locations identified by Reid's research. The first
applications have now been approved and funded to a total value of
>£250k. This agri-environment scheme has therefore changed agricultural
practices on Islay, and injected substantial resources into the rural
economy.
Reid's quantification of recent unprecedentedly high juvenile mortality
prompted an SNH programme of emergency supplementary feeding, now funded
for 4 years, and an associated policy review [8, 9]. This programme has
added a new dimension to conservation policy, and is directly impacting
the state of the protected population [d].
Reid pro-actively disseminated the research to conservation managers,
policy-makers and practitioners, farmers and the wider public through
ongoing activities designed to maximise impact:
(i) The NERC Knowledge Transfer research project culminated in the
production of a major research and policy report [e]. This summarised the
key policy-relevant results of the primary research, and included a set of
policy recommendations that were agreed through a two-day round-table
discussion that involved Reid, conservation managers and practitioners
from SNH and Royal Society for the Protection of Birds (RSPB), farmers and
scientists from Scotland's Rural College (SRC) and University of Glasgow
[e]. These recommendations were used to inform agri- environment policy
incorporated into the SRDP [c], and SNH's policy of funding emergency
supplementary feeding [8,9].
(ii) The `Scottish Chough Forum', which comprises Reid and
representatives from SNH, RSPB, SRC, Scottish Chough Study Group and the
University of Glasgow, meets twice per year to ensure ongoing effective
exchange between science and policy [b].
(iii) As part of the NERC Knowledge Transfer project an
international stakeholder conference was held in Ayr, Scotland in 2007.
Approximately 90 delegates attended the two-day workshop, including
scientists, policy makers and practitioners from England, Wales, Ireland,
France, Spain, Italy, Portugal and Canary Islands as well as Scotland.
This facilitated the transfer of new scientific understanding, and views
of emerging threats, to policy makers across Europe. This meeting sparked
follow-up international meetings in Canary Islands (2011) and Portugal
(2013).
(iv) Reid presented her research to public audiences of farmers
and birdwatchers [f]: Scottish Ornithologists' Club (2011); Islay Farmers'
Association (2008 [g]); Scottish Ringers' Conference (2007). Reid also
gave major invited plenary lectures to the public at the British Trust for
Ornithology Annual Conference (2011), and to policy makers and
conservation scientists at the Norwegian Academy of Sciences conference on
`Sustainability Conservation' (Oslo, 2010).
Reid's work has directly impacted upon public policy and policy-makers;
on resultant agricultural and conservation policy and hence on the
environment; and on public understanding of and participation in
conservation science. It has directly impacted on governmental
conservation management by providing information and understanding on
which key policy discussions were focussed and policy decisions were based
[a-e]. In so doing, it has also benefitted the broader research and
conservation community in Scotland by providing a successful and ongoing
example of rigorous conservation science being translated into policy
[b,h]. It has directly impacted on agri- environment and land management
policy and on Islay's rural economy by leveraging substantial funding for
chough-friendly farming [c]. Such schemes are critical to maintaining
viable agriculture in Less Favoured Areas. Importantly, it has directly
impacted on the agricultural environment that red-billed choughs inhabit,
positively impacting population size and persistence. This further
benefits Islay's economy because choughs are a major ecotourism
attraction, thereby supporting visitor accommodation and hospitality
outlets and transport infrastructure.
The impact claimed as defined by REF therefore includes: environmental
policy decisions and planning decisions were influenced by research and
management, and conservation of natural resources has changed.
