As mentioned before, the animals at Durrell form a safety net population; should their genetic information ever be called upon, as well as being ambassadors for their species. An area of the world that is developing extremely fast and pushing several species to the brink of extinction is the poorest island in the world – Madagascar. This is an island which Gerald Durrell felt extremely passionate about. It is in such major trouble due to agricultural practices being forced upon the Malagasy people to provide more of the things that the richer parts of the world desperately crave such as cinnamon, cocoa and coffee. Lemurs are endemic to Madagascar, as are all terrestrial mammals found there and Durrell boasts six different species in its collection including the aye-aye. Lemurs form part of the suborder Strepsirhini (prosimians) within the order Primates and have evolved into an extremely diverse collection of species, each of which has very specific habitats and niches.
The mixed group, whose territory
spans one whole side of the lake, consists of two Black-and-White ruffed
lemurs, one Red-fronted Brown lemur and seven Ring-tailed lemurs. The group has access to several trees,
the tallest around 15-20m in height, of which, some are used for feeding via an
attached rope-and-pulley system; delivering fruit high into the tree top.
It’s fantastic to see the lemurs
make full use of the natural resources that are available to them, especially
in this recent heat-wave. During my day off today I spent some time at the park
watching the way the different animals behave over long periods of time, as
well as how the public feel about the various exhibits and animals they see.
Whilst watching the lemurs today, at some points it appeared to fellow
observers that what they were seeing was an outdoor area which had been
abandoned by its usual inhabitants. Only when the ruffle of leaves was seen and
heard was the audience engaged. Simultaneously the black and white extremities
that hung from the Ring-tailed lemurs suddenly became clear and the finger
pointing began, with keen-eyed parents pointing out to their children the
locations of the arboreal acrobats.
Environmental enrichment (EE) can
be any process or item that an animal is exposed to, with the aim of encouraging
natural behaviours whilst preventing boredom and stress. According to the zoo keepers I have been
working with, visitors commonly ask what sort of EE programme the lemurs in
this area of the park are in receipt of. The answer is that there is no structured
EE plan other than a diet that varies on a daily basis. The reason for this is that
the lemurs are kept in a fairly wild environment, regularly encountering plenty
of wild animals such as moorhens, seagulls, rabbits and countless invertebrate
species; not to mention the other species of lemur that share the enclosure.
With all this activity going on it would be more difficult to switch off than it would be to remain active and engaged in these busy surroundings!
British wildlife a few inches away
from the lens is no problem for my Samsung PL80. The sort of photography needed
to capture certain environments such as this exhibit, on the other hand, is embarrassingly
beyond the capabilities of my compact camera. The photos I’ve taken don’t do
justice to how imaginative and complex the lemurs’ outdoor area is, however,
they do show the scale of the area and how it engages the visitors, so much to the
point that, in my opinion, they almost forget they are in a zoo. I believe that
the large (in zoo terms) distance between animals and visitors becomes less of
an issue when animals are seen behaving so naturally in their naturalistic
habitat. The fact that there is no visual barrier, e.g. glass; mesh; netting, whatsoever
between “us and them” must surely assist in reducing visitor frustration when
trying to capture that perfect action-shot.
I hope this exhibit is a shining example to other zoos; that both maximum animal welfare and visitor satisfaction can be achieved when an enclosure is really well thought through and animal welfare is at the top of the agenda. Too often zoos appear to be “animal collections”; cramming in as many species of mega-fauna as possible to better appeal to the public, rather than having a strong mission statement, which the zoo itself reflects. I have realised that an investment should really be made by zoos to provide the best possible enclosures for a select few species rather than mediocre facilities for several. We already know that better captive conditions, backed up by strong research, correlate with reproductive success and low aggression levels (to name just two), so why not listen to what the results are telling us? This is why I believe that Durrell is setting the benchmark for so many zoo practices; it looks at what the animals need and everything else comes second (…third, fourth, fifth etc).
