Former director Jeremy Mallinson buries a time
capsule in the new Kirindy Forest exhibit to mark
50 years of saving species from extinction.
The Trust welcomed its first trainee in
1979, finally breathing life into Gerald
Durrell’s dream of a ‘mini-university’ that
would help transfer all the knowledge
and skills that the Trust’s staff were
building up to those on the front line of
conservation. More than 1800
conservation professionals have now
attended ITC courses both in Jersey
and overseas, and we are continuing
to expand the topics we offer as well as
find new ways to support graduates
once they return home.

Gerald Durrell opened his zoo in
Jersey in 1959. Our 50th anniversary
year was filled with celebrations, from
an open day that attracted over
14,000 people, to a concert that saw
the premiere of the Durrell suite by
Derek Lawrence, celebrating some of
the species Durrell has worked with.
As we reach the end of the year, a new
exhibit has just opened in the Walled
Garden. It will be home to a variety of
Madagascar’s wildlife, and especially
species from the island’s dry forests.

neighbouring property of Les Noyers,
Initially just a residence, over the next
few years the buildings were
transformed into a teaching centre
and in 1984 the International Training
Centre was formally opened.
Education joins the ITC!
There have always been
overlapping areas between training
and education (or Visitor Services and
Education to use its full title) at Durrell,
and last autumn the Trust’s senior
management team took the
opportunity to review how the two
departments operated and decided to
split Visitor Services and Education into
its two constituent parts. Visitor Services
took on responsibility for the animal talks
programme on site and other visitorrelated activities, while the education
staff joined the training centre to
create one department capable of
teaching anyone from 3 to 103!
Jill Key
The ITC grew in 2009 as it took on the teaching activities of the former Education
Department. Conservation Education Officer Naomi Webster describes how
the two teams have been integrated into one.
The move has allowed the training and
education staff to work more closely
together and give each other advice,
support and assistance. It is also an
exciting opportunity to review the
education activities offered now and
develop new ideas for the future.
One such activity is the brand new
Conservation Science School, a threeday course for 15-18 year olds, which
ran for the first time this summer. The
course was thoroughly enjoyed by all
the participants and we hope to run
the course twice in 2010, in February
and August.
Meet the new staff...
Conservation Education Officer Naomi
Webster attended the ITC’s summer
school in 2004, and then volunteered
with Durrell’s education department
before being offered a job. Naomi’s
responsibilities include teaching school
groups, running workshops, writing and
producing newsletters for Dodo Club
members and working on the signage
and interpretation in the grounds. She is
currently writing and directing her third

The Marañón poison dart frog:
concerns and opportunities
The Marañón poison dart frog
(Excidobates mysteriosus) is endemic to
the upper Marañón river basin, near
Cordillera del Cóndor in the northeastern Peruvian Andes. Originally
Dendrobates mysteriosus (Myers, 1982),
it has recently been reclassified
(Twomey and Brown, 2008).
The frog is categorised by the IUCN as
Endangered, because it is threatened
by habitat loss and fragmentation and
the illegal collection of individuals for
export to countries such as the USA
and Germany. Conservation action is
therefore needed.
The frog in its typical habitat, bromeliads.

biologist Germán Chávez, and myself.
The first step was to
contact people in the
type locality, Santa Rosa
de la Yunga, in Jaén
province, department of
Cajamarca. During our first
field trip in May 2009,
helped by German
herpetologist Claudia
Koch, we contacted Mr Napoleón,
manager of the Asociación de
Conservación y Ecodesarrollo Rural
(ACONDECOR), who keeps watch over
a little conservation area known as El
Tupire, where there are several patches
of E. mysteriosus habitat. This species is
closely associated with bromeliads of
the genus Aechnea, which live mainly in
precipices and rocky areas, and also in
some trees. We also evaluated other
areas, such as Cerro Casapita and La
Yunga, where the first individuals were
recorded by Rainer Schulte in the 1980s
(Schulte, 1990).

Field work A grant
sponsored by
Conservation
International (CI) and
the Asociación Peruana
para la Conservación
de la Naturaleza
(APECO),‘Programa Iniciativa de

species in its natural habitat, update its
population status and distribution
patterns and investigate any infectious
diseases that might be present. The

To assess health status, we collected

conservation initiatives in the locality, to
maintain the habitat of the species.

more than forty individuals, but although
this number seems quite high, it is very
dependent on habitat conservation.
We also observed some colour
variation in individuals from different
localities, expressed in the dark
background pattern of some
populations. Molecular studies could
help elucidate this.
For chytridiomycosis PCR analysis, 21
samples will be sent to the Veterinary
Diagnostic and Investigational
Laboratory at the University of Georgia,
USA. In a previous study, Twomey and
Brown (2008) found no evidence of
Batrachochytrium dendrobatidis, the
fungal agent of chytrid disease, in eight
samples. We believe that the species’
habit of using bromeliads could be
protecting it from chytrid, but more
data are needed.
The Marañón poison frog is a flagship
species that deserves urgent
conservation action to maintain wild
populations. In order to do this, more
research is needed, as well as a strong
programme of environmental
education with the local people.

examined by experts for impacts on
amphibian breeding habitats.
Options also need to be explored for
creating new conventional PAs,
conservation reserves and community
reserves dedicated to amphibian
species in different parts of the country.
Wildlife biologists should be attached to
these areas to produce species
inventories, monitor amphibian
populations, enumerate impacts on
amphibian populations and demarcate
crucial breeding habitats for
amphibians. The workshop also
suggested revising the Indian Wild Life
(Protection) Act, 1972 to include more
species.

Finally, all concerned – government and

facing amphibians and the steps we
need to take to address them.

water swamp forming the lower part of
the Ganges delta. This natural resource
is shared by both Bangladesh and India.
Sunderban, the Indian portion, is 6–9
metres above sea level. This tidal
estuary covers an area of over 4000
km2, about 2300 km2 of which is

so far, ecotourism now constitutes a
growing threat to conservation of
biodiversity in the Sunderban, both
directly and indirectly. Animals that are
subjected to disturbance will spend less
time feeding and resting and more
energy on trying to move away from
the source. Disturbances are mostly
caused by the tourists themselves, their
vehicles, motorboats etc. Evidence of
this type of behavioural change is
evident in almost all species, especially
tigers, monkeys and birds. Recent
studies have also revealed that animals
Subhransu Pan
are subject to changes in physiological
parameters, for example in stress
hormone levels, food intake, sleep and
metabolism. Disturbance is most
prominent during breeding periods and
juvenile stages, leading to overall
breeding failure, a serious threat to
population maintenance and survival.
Ecotourism is also resulting in habitat
destruction of the Sunderban. Damage
to vegetation, waste, cooking fires and
leakage from fuel tanks are affecting
both terrestrial and marine biodiversity.
Indirect effects arise from construction
for the tourism industry and the use of
natural resources to meet the demands
of tourists. Along with the unrestricted
flow of tourists, poachers are also
getting easy access in the forest.
Subhransu Pan
Taking action With the rapid growth of
tourism, steps need to be taken to
check the erosion of biodiversity:
- Allow tourism only to a level that is
affordable without loss of biodiversity
- Increase empathy among local
people for conservation

- Restrict construction within the

- Check vehicles and motorboats for

- Restrict dumping of waste by tourists
within the conservation area and
make aware them of the adverse
effects of this
- Strictly enforce rules and regulations
regarding ecotourism.

sustainable development will be in vain
if environmental degradation and
depletion of natural resources continue
unabated.’
So we should always promote ecotourism for the benefit of conservation,
not to its cost.

Conservation breeding of hoolock
g ibbons: a success story
Hoolock gibbons are the only apes
found in India. The state of Arunachal
Pradesh is home to both species of
hoolock: the eastern hoolock (Hoolock
leuconedys) is estimated to number
about 150 animals, and the western
hoolock (Hoolock hoolock) about 200.
with the approval of the Central Zoo
Authority.
To start with, five pairs of eastern
hoolocks, and five juveniles, were
rescued from the Delo area in
Arunachal Pradesh. The rescue
operation targeted animals that had
been injured by dogs, gibbons
debilitated by heavy parasite
infestations, juveniles that had been
rejected by their mothers, or isolated
apes. Family members of the rescued
animals were also captured to avoid
displacement.
Jikom Panor
Habitat loss and fragmentation are
jeopardising the gibbons’ survival. The
major threats are the expansion of tea
plantations following a blanket ban on
timber extraction; agricultural practices
such as Jhum cultivation, a traditional
method of ‘slash and burn’; and
encroachment by populations from
neighbouring countries. All
these drastically reduce

included both animal and plant protein
along with vitamins, minerals,
carbohydrates, sugar and fat. A variety
of tender leaves is provided. Some of
the ingredients, such as sweet potato,
were not easily accepted by the

animals were given only those
ingredients until they accepted them.

the centre are given worm treatment
and screened for zoonotic diseases
every six months. Hygiene, both
personal and in the cleaning of
enclosures, utensils, etc, is strictly
monitored. Health problems include
viral influenza (which can develop with
poor housing, cold wet weather and a
lack of nesting trees) can be fatal if
immediate treatment is not given for
secondary infection and pneumonia.
Toxocara infection is common, and
stools are examined for parasites every
month. De-worming is only done if ova
are detected to avoid drug resistance.
Dehydration is often seen due to the
gibbons’ low water intake. Hoolocks
usually wet their fingers in dew drops or,
in captivity, bowls of water, and lick
them. They are also often seen licking
their own urine.
Future plans The Itanagar zoo
successfully bred three hoolock
gibbons during 2008, and reintroduction
is the ultimate goal of the project. This
breeding centre may act as a nodal
training centre for captive breeding
and management of hoolock gibbons
both in situ and ex situ in the future.
Strategies for monitoring and modifying
management practices both in
captivity and in the wild will be
developed, and plans will be initiated to
rescue and rehabilitate animals from
the Delo area and other degraded
habitat.
Jikom Panor attended the Endangered Species Recovery course in 2006 and is
the Veterinary Officer for the Biological Park, Itanagar. Please contact him for
further information on the management of hoolock gibbons in captivity,
including diet, anaesthetics and health problems.

Memories of Jersey ...
Stas Vostoko
v
ostokov
([email protected]), who
trained at the ITC in
1995, has written a
fictional story in Russian
based on the time he
spent in Jersey and the
friends he made.
Gorilla
The book’s Russian title could be
translated as ‘The island dressed in
jersey’ or perhaps ‘The island in jersey’.
‘You meet a lot of funny situations when
such different people from the other
ends of the world meet in one place,’
Stas says.
The book also describes the work of the
Trust, its aims and methods, and touches
upon the history of the island. Other ITC
graduates are likely to meet a lot of
familiar people if they read the story.
The book was published
in 2007 by the Vremya
publishing house in
Moscow and has
received two national
literature prizes. Stas
illustrated the story with
his own drawings,
several of which are
reproduced here.

... and of Gerald Durrell
I have been fascinated by animals ever
since I can remember. My first meeting
with Gerald Durrell took place in the
school library when a friend handed me
a copy of Three Singles to Adventure.
On reaching
home I
jumped at the
book and had
the joy of
journeying to
British Guyana
with my hero. I
went past
magical rain
forests full of
birds and
beasts of

and

was with Durrell when he caught
teguxins, sloths, eels, iguanas, and, of
course, Amos, the giant anteater.
made friends with many other colourful
characters: Ulysses the Scops owl and
Quasimodo the pigeon in My Family and
Other Animals; Claudius the tapir and
Whiskers the emperor tamarin in
Menagerie Manor; gorillas Nandi,
Npongo and Jambo, and Oscar the
orangutan in The Stationary Ark. The list
is endless and includes humans like
Gerald’s family, Larry, Leslie, Margo and
Mother.
I feel that Gerald Durrell portrayed the
human race as it looked to him.
Perhaps that is what made his books so
enjoyable. His last book, Marrying off
Mother, was sentimental but it still
provides us with a fine picture of human
nature. He not only loved animals but
enjoyed life and wanted us to enjoy it
with him.
I had one more dream to fulfil – to get
associated with Gerald’s zoo, the
Jersey Wildlife Preservation Trust (as it
was then). That dream was realised in
October, 1991.

describes here how he first became
aware of Gerald Durrell through his
books. This is an edited version of an
article first published in March 1995, in
VOICES, The Statesman in School.
Seven days seemed too short a period
with Durrell but that was the
introduction to a friend – who would be
my hero, mentor, guru and guide for the
next six years until his death in January
1995.
As I grew up, to the consternation of my
parents and relatives, my interest in
animals, far from abating, grew stronger
by the day, and with it grew the
friendship with Gerald Durrell. I slowly
got hold of more Durrell books and

Durrell Conservation Learning
Network
The Durrell graduate network was
established in the early 1990s. We now
have getting on for 1800 people on our
database, and with the launch of our
new web-based network we hope we
will be able to maintain regular contact
with a large proportion of them.
An ITC listserve was first established in
2000 to allow us to pass on useful
information and for graduates to use as
a means of keeping in touch and
getting support for the issues they were
facing in their own work. After a recent
rethink of the best way both for the ITC
to keep in touch with its graduates, and
to develop connections between
graduates so that they can help each
other, we have now launched the
Durrell Conservation Learning Network.
In order to be effective, training
courses must be part of a continual
process of capacity building. The Durrell
network has the great strength of being
developed from people who have all
been involved in the training
programme in some capacity. Its main
aim is to be an information exchange:
as well as graduates from Durrell
training programmes, we will be inviting
Durrell staff, members of partner
organisations, and other conservation
professionals who express interest to
join. These are Durrell’s Army - a
powerful force for change.
2009: the new network In 2009 funds
were secured from the HDH Wills 1965
Charitable Trust to promote the
network and support the development
of a new internet-based site, linked to
the ITC webpage.The aim was to
establish a system that is simple and
user-friendly, so that less skilled internet
users or those with limited access will be
20
able to utilise enough of the network to
benefit. The site is accessible to network
members via a password.
As well as the internet home for the
network, a first regional meeting is
proposed for 2010 and north-east India
has been suggested for the venue.
Network mission The DCLN aims to
help ITC graduates to turn their
conservation training into conservation
actions through technical support and
encouragement.
The web-based network site was
launched in October 2009 and offers
several new ways of communicating. A
news section allows both the ITC and
graduates to pass on ideas for funding,
contribute news about conservation
issues, and celebrate activities and
achievements. Discussion forums will
help promote peer learning, generate
new ideas and provide technical
advice and support, while a
downloads section makes documents
such as articles and application forms
easily accessible.
A searchable database of network
members will be added to the website
in 2010, so that members can find other
graduates in their professional and
geographic areas.
Please join! All graduates of ITC
courses can join the network, and
ultimately its success depends on
you! If you are not already
registered, please sign up via the
graduate network section of Durrell’s

Save Eastern Swamp Deer from Extinction Threat - A
Pilot Study
With about 600 individuals left in a single population in
Kaziranga National Park in India, the eastern swamp deer
Cervus duvaucelii ranjitsinhi is facing the threat of extinction,
and creating a second population in a safer habitat has
become a top priority. Manas National Park, where the
species existed until the late 1980s, has been identified as a
suitable location. Although the deer became locally extinct
in Manas as a result of poaching during a period of unrest,
peace has returned to the region, the habitat is probably
intact and a reintroduction is planned.
Rathin’s project involves a pilot study to obtain information ahead of the
reintroduction programme. He will survey potential habitat for the species in
Manas National Park; study habitat utilisation by eastern swamp deer living in
Kaziranga National Park for comparison; assess the health of the parent
population in Kaziranga; record and evaluation protection measures in Manas;
engage stakeholders and decision makers involved in the planning process; list
potential problems and threats and methods of overcoming them; and list the
official formalities that need to be observed so that the reintroduction project
can be properly planned and executed.

Cerro
Colorado
Central Mexico
When the Biosphere Reserve of Tehuacan-Cuicatlan in
Mexico was established, an area of 22,425 ha known as
Cerro Colorado was left out despite its high importance for
conservation and the possibility that it could serve as a
corridor for several species in the region. Local people are
interested in having the area declared protected and
included in the management programme as they will
benefit in terms of government aid, and have agreed to
start a monitoring programme on their properties.
The area is especially important as there are historical reports of jaguars in the
area. Confirmation of the presence of jaguars would modify the current
22
distribution of the species and help to indicate the existence of a corridor in the
area, part of a corridor that in theory connects populations in northern and
southern Mexico.
Camera traps and transects will be used to record the mammal species present
in the area. Monitoring will be done during the dry season. The cameras will be
placed along trails, dry river beds and dirt roads at a height of 30-40 cm and left
for a month, after which they will be rotated to different sites in order to cover
the most terrain possible. Photos will be used to determine relative densities of
the species, and in the case of species where it is possible to recognize
individuals, densities will be calculated. The results will be integrated with those
obtained by other groups and presented to the state authorities in order to
justify the creation of the protected area.

Scientific Publication Writing Course
Kanchana has been involved in various scientific research
projects for the past eight years, some species-specific
and others habitat or community-based. The organisation
she started, Eco-Friendly Volunteers (ECO-V) has just run its
first training course for young people.
The results of the projects carried out by Kanchana and
ECO-V have been used in local awareness programmes
and published as local project reports and some have
been presented at international conferences on
conservation biology. In order to gain more international recognition for ECO-V’s
work, Kanchana now wants to develop her scientific writing skills so that her
team’s research results will be accepted for publication in standard journals,
enabling ECO-V to communicate more effectively with the international
conservation community.
Kanchana hopes to have papers accepted for publication in peer-reviewed
journals and for presentation at international conferences within six months of
completing the course.
