Summary of the impact
Research on the status, distribution and ecology of sea turtles at the
University of Exeter has
driven national and international conservation policy, engaged millions of
people worldwide and
raised substantial funding for conservation. Governments including the UK,
Cayman Islands,
Cyprus and Gabon have used this research in making legislation and
multi-million pound
management decisions. Development of open-access animal tracking tools has
facilitated a global
network of over 135 countries, with more than 300 projects tracking
thousands of animals from 118
species. The ability to adopt tracked animals online has attracted
millions of visitors and raised
funding for conservation projects world-wide.
Underpinning research
Annette Broderick and Brendan Godley joined the University of Exeter in
2003. During this period
they have been funded by grants of over £1.4million (e.g., by Defra, FCO,
Darwin) and have led
marine turtle research (particularly in the areas of species distribution,
impact upon fisheries and
the development of a global satellite tracking system) in >20 countries
resulting in >100 peer
reviewed publications.
This research has highlighted the status and distribution of marine
turtle populations at numerous
sites around the world (Ascension Island, Cayman Islands, Cyprus, Gabon).
Data from long-term
population studies has been used in IUCN Red Listing (i.e. species at
threat of extinction) and
critical analysis of such global assessments and informed management
decisions [1]. Increasing
knowledge of spatial distribution has allowed key habitats for protection
to be targeted [2] and,
more recently, allowed a global test of the efficacy of marine protected
areas for one species [3].
Research in Gabon (Darwin Initiative 2009-2012; NOAA 2006-2008) not only
demonstrated that
Gabon hosts the world's largest nesting colony for the leatherback turtle
[4] but also highlighted the
inadequate scope of the extant marine protected areas for protecting
turtles during the nesting
season [2] which not only leave the parks, but cross into neighbouring
countries. Tracking after the
breeding season highlighted a range of migratory strategies spanning the
South Atlantic. These
strategies expose turtles to some of the world's highest levels of
longline fishing, in addition to
areas with coastal gillnet fisheries.
Research has focused on the likely impact and mitigation of direct and
indirect fisheries on marine
turtle populations, and numerous publications from the group describe
participatory work with
governments, NGOs and fishing communities. Recommendations resulting from
this research have
led to legislative change and future studies. In the Cayman Islands for
example, there is a legal
harvest of marine turtles, and past over-exploitation has led to greatly
reduced nesting populations.
Research (FCO/Defra 2004-2006, Darwin Initiative 2005-2008) has shown that
both breeding and
nesting occurred outside a long-established closed season, and size limits
were allowing rare and
reproductively valuable adult turtles to be taken. In their 2007 paper [5]
Godley & Broderick
recommended legislative changes for the fishery.
Research utilising satellite tracking led to the development of the
online Satellite Tracking Analysis
Tool-STAT [6] which facilitates animal tracking and public data-sharing
for workers without access
to advanced spatial analysis and web design skills. This has been a huge
success and has now
facilitated the work of global network of over 300 projects involving
>7600 animals of 118 species
from a wide range of taxa.

Details of the impact
Informing conservation agency decisions:
Data from the group's long-term monitoring projects in the UK Overseas
Territories and Cyprus
have been used in both local conservation and global IUCN Red List
Assessments and in support
of a change to regional assessments for marine turtle species (section 5;
source 1). In Cyprus,
data have provided the basis for the designation of five Special
Environmental Protected Areas
(SEPAs) containing turtle nesting beaches. These sites have also been
identified as potential
Natura 2000 sites and are awaiting designation to this ecological network
of protected sites by the
European Union (section 5; source 2).
Research in Gabon has been influential in the rescheduling of
multi-million dollar seismic surveys
(section 5; source 3); published tracking data were used to create maps of
risk highlighting that
planned seismic work held potential for high levels of interaction with
breeding turtles and moves
afoot to increase the size of marine protected areas. It has also
galvanized the inception of a
marine fisheries observer programme funded by governments of UK and USA
and the NGO WWF.
Informing policy debate and influencing policy change
In the UK Overseas Territories (OTs) the University of Exeter group have
worked with
governments across the region (Anguilla, British Virgin Islands, Cayman
Islands, Montserrat, Turks
and Caicos Islands) to create a baseline to inform local conservation
policy and the UK
Government's position with regard to key biodiversity agreements such as
the Convention on
International Trade in Endangered Species of wild fauna and flora and the
Convention for
Migratory Species (section 5; source 4). This resulted in a major
report commissioned by
Defra/FCO (section 5; source 5), subsequent associated peer reviewed
articles (eg Bell et al 2007
Section 3) and a National Biodiversity Action Plan for the Cayman Islands
(http://www.doe.ky/nbap/
See section 5; source 6) and Letter and an Action Plan for the
Coastal Biodiversity of Anegada,
British Virgin Islands (section 5; source7).
Recommendations to the Cayman Islands Government (section 5; source 5)
were adopted by the
Cayman Islands Department of the Environment (section 5; source 6) and in
2008 legislation was
amended to extend the closed season and include a maximum size limit as
recommended by our
group (section 5; source 8). These measures have undoubtedly contributed
to the upward trend
now seen in this population (communication from Scientific Research
officer, department of the
environment Cayman Islands government).
In Anguilla recommendations resulted in an extension to an existing
moratorium prohibiting harvest
until long-term studies support changes to legislation and in the Turks
and Caicos Islands, in
conjunction with the Marine Conservation Society (UK), research by the
group has been used in a
draft management plan to introduce a closed season and maximum size limit
for harvest.
Increasing capacity for conservation
The establishment of STAT (Satellite Tracking Analysis Tool) has empowered
workers without
access to GIS, many in developing nations, with advanced spatial analysis,
oceanographic
expertise and web design skills. This has been a huge success and has now
facilitated the work of
a global network of 300 projects involving >7600 animals of 118 species
from a wide range of taxa.
The public facing pages of STAT (www.seaturtle.org/tracking)
have been visited over 16 million
times since 2004. This has allowed tracked animals to be adopted online,
provided data to schools
for use in lessons and has seen >£200,000 raised for conservation. The
paper describing this tool
(Coyne and Godley 2005) has been cited as the methodology of an
ever-increasing number of
studies (160+ cites Oct 2013).
In addition, Broderick and Godley have supervised over 20 international
post-graduate students
(including 6 from the UKOTs for whom full scholarships were secured from
DfID/FCO), many from
developing nations, where building capacity for biodiversity conservation
is critical.
