Summary of the impact
During the last 10 years Cardiff University researchers have developed
and applied a range of genetic and molecular analysis techniques to inform
conservation and biodiversity policy and practice in regions around the
world where specific species and biodiversity are under threat. Genetic
research on orang-utans and elephants in the Kinabatangan Wildlife
Sanctuary in Borneo has guided strategic action plans for these species.
Cardiff's molecular censusing and genetic analysis of giant panda
populations in China have directly informed the strategic relocation of
individual animals into isolated populations in the wild to preserve the
genetic diversity of the species.
Underpinning research
Interventions to manage endangered species often lack a scientific basis,
especially when it comes to preserving the genetic diversity of species.
Although the 2020 Convention on Biological Diversity (CBD) explicitly
calls for action to assess genetic diversity for the first time, there is
still little guidance on evidence-based approaches to achieve this aim.
A team of researchers from Cardiff University, led by Professor Mike
Bruford (Professorial appointment, 1999-present), worked with conservation
partners in Malaysia and China over a period of a decade from 2000 to
collect and analyse genetic and demographic data on several `flagship'
endangered species: orang-utans, elephants and the giant panda.
Orang-utans and elephants in Borneo
For orang-utans, between 2000 and 2003 the Cardiff researchers provided
genetic analysis and modelling as part of a collaborative Darwin
Initiative project. The other project partners were Malaysia's Sabah
Wildlife Department (SWD), the management authority for Lower Kinabatangan
Wildlife Sanctuary; the University Malaysia Sabah, which contributed an
MSc student for research activities; and the Non-Governmental Organisation
(NGO) Kinabatangan Orang-Utan Conservation Project, which orchestrated the
collection of faecal samples and produced demographic data and habitat
assessments for the sanctuary's orang-utan population.
PCR genetic profiling, including mitochondrial DNA analysis, was carried
out for over 200 individual orang-utans. Bruford combined the genetic data
with demographic information (e.g. the ranges and territories of
individuals, offspring, breeding rates etc.) to create a predictive model
that suggested the Kinabatangan sub-population would be extinct within 50
years without action to reconnect the Kinabatangan riparian forest (now
largely disconnected due to palm oil related land conversion). The model
also showed that the relocation of individuals would add diversity to the
isolated gene pools3.1-3.3.
The Cardiff team provided similar research expertise between 2005 and
2008 to build a predictive model for the elephant populations in Borneo as
part of a second Darwin Initiative project in collaboration with SWD,
University Malaysia Sabah and World Wildlife Fund (WWF) Malaysia (which
provided satellite tracking data). Simulations revealed that habitat
fragmentation increases the size of an elephant's home range because they
are forced to move further afield to find food. These `vagrant' elephants
would be more likely to encounter and enter into conflict with humans3.4-
3.5.
Giant pandas in China
In China, Bruford and Dr Benoit Goossens (Senior Research Associate,
2005-present) from Cardiff worked with Fuwen Wei, Department Director of
the Institute of Zoology of the Chinese Academy of Sciences. The Cardiff
team carried out molecular censusing, developed through the Darwin
Initiative projects, on 250 samples of giant panda faeces taken from the
Wangland reserve to produce a DNA profile and generate a more accurate
estimate of panda populations. Previous sampling methods suggested there
were only 27 individuals, but Cardiff's research provided robust evidence
of at least 66 individuals. The work revealed the dispersal patterns of
the giant pandas during 2006 and 20073.6.
The study also showed that females disperse over larger distances than
males, perhaps because the number of birthing sites has fallen due to the
degradation of old-growth forest and the lack of tree cavities at a
suitable temperature3.6.
The two Cardiff researchers also worked with the Beijing Genomics
Institute (2008-2010) to analyse the genetic structure of giant panda
populations in China to determine the interconnectivity between
sub-populations. Cardiff's role in the project was to assess the genetic
diversity of giant panda populations. This work showed for the first time
that the species possesses substantial genetic variation and they are not
at an evolutionary `dead end'. However, the profiling highlighted the
genetic differences between isolated mountain populations3.7.
Giant panda genome project
Cardiff's substantial involvement in the genetic analysis of giant pandas
led to an expanded sequencing effort and the publication of the giant
panda genome in the journal Nature3.8. The giant panda is the
first endangered species to have had its genome sequenced.

Details of the impact
Shaping conservation action in Borneo
Cardiff's genetic analysis forms a central part of the Orang-utan State
Action Plan that was written by Bruford and Goossens in collaboration with
Sabah Wildlife Department. The plan was presented on 10-11 June 2010 for
endorsement by the Sabah State Cabinet and formally published and launched
in January 20125.1.
Following the similar project focusing on the Bornean elephant, Goossens
was charged, together with a member of the Sabah Wildlife Department, with
producing the Elephant State Action Plan which has now also been endorsed
and published by the Sabah State Cabinet 5.2. By identifying
the link between fragmentation and home-range, a key element of this
Action Plan is to reconnect the forests of the Kinabatangan to form a
`corridor of life' along the river.
The species Action Plans have helped Malaysia (and especially the Sabah
Wildlife Department) to meet its obligations under the Convention on
Biological Diversity.
The Action Plans were launched at a workshop in 2012, attended by
conservationists and representatives from the palm oil sector to discuss
the implementation of the plan and suitable solutions to the shrinking
orang-utan and elephant habitats. Goossens presented an overview of the
scientific evidence and forecasts produced by the Cardiff team; Bruford
facilitated a plenary discussion on strategies to harmonise wildlife
conservation and the development needs of the region 5.3.
The Action Plans are now being implemented in Sabah. A key element of the
Orang-utan Action Plan has been the extension of the rope bridge programme
to facilitate interactions between previously isolated populations.
Photographic evidence in 2010 has shown that the primates use bridges
installed above Kinabatangan tributaries in a pilot scheme to cross these
natural barriers allowing them to roam further afield 5.4.
International training for evidenced-based conservation
During the elephant project, Cardiff University also developed a plan to
establish a field centre in partnership with the Sabah Wildlife Department
in the Lower Kinabatangan Wildlife Sanctuary. Following substantial
investment from Cardiff, the Danau Girang Field Centre (DGFC) opened in
July 2008. During its first five years the centre has hosted 24 training
courses for international and Malaysian scientists and students; it has a
high local media profile.
Supporting livelihoods and sustainability in Borneo
DGFC contributes to the local economy as it employs twelve local people,
including a centre manager. The centre also promotes sustainability in the
area through active engagement with the oil palm sector. It helped to
organise the Sabah Conservation Colloquium 2012 and collaborates with
Yayasan Sime Darby, a palm oil funded conservation charity, to study and
conserve the proboscis monkey in Sabah 5.5.
The creation of DGFC has helped to precipitate the closure of an
unlicensed tourist site called Uncle Tans, which was having a significant
negative effect on the environment.
Improving Chinese conservation practices
In China, Cardiff's collaboration with the Institute of Zoology, Chinese
Academy of Sciences has built the Institute's capacity in non-invasive
genetic analysis. Since the initial studies of the genetic structure of
the giant panda, Chinese scientists have now developed a full assessment
of the greater Shangri-La ecosystem 5.6-5.7.
The genetic census of giant pandas in 2006 spurred a revision of the
sampling strategy for China's fourth national giant panda survey;
molecular censusing will be carried out across the entire geographic range
of the survey. The authorities will use the more accurate population
estimates to refine the protection measures for each region of the giant
panda's range5.6-5.7.
Cardiff's work on the genetic structure of panda populations has been
instrumental in guiding the strategic movement of individual animals into
the dwindling Xiaoxiangling population at the south of the species' range5.8.
This practice of `targeted translocation' is also included in the revised
management guidelines for the fourth national survey on giant pandas 5.6-5.8.
Conclusion
The ultimate impact of these management recommendations based on
Cardiff's research will take decades to evaluate, since they are measured
over generational timescales. However, by using evidence-based management
practices, these emblematic species and others that benefit from the same
scientific approach, will have a much greater chance of long-term
survival.
