Small Cat Conservation
Program
By any measure, the taxonomic family that we call the Felidae
has been extraordinarily successful during its brief existence
in Earth’s long history. Just in the past 10 to 12 million
years, a burst of evolutionary divergence from a common ancestor
produced the 36 distinct cat species that we know today. Wild
cats are found on every continent except Antarctica and Australia
and in a diversity of habitats ranging from desert to swamp to
rain
forest
to mountain ranges. The domestic cat sitting on your couch is
one vestige of that felid explosion, being only 3 to 5 thousand
years of domestication removed from its closest wild relative,
the African wild cat.
The world’s cat species share not only a common ancestry and basic body
design but also, unfortunately, an unpredictable future. The plight of the larger
cats, such as the tigers, the cheetahs and the snow leopards, has received most
of the attention in the popular press and conservation circles and justifiably
so since they may be facing the most dire threats of extinction due to habitat
loss and direct human persecution. However, almost totally ignored in this groundswell
of conservation concern are the more diminutive members of the felid family,
those small cats weighing less than 20 kg (~45 pounds) that actually comprise
28 of the 36 cat species of the world. Some may be familiar to you – the
ocelot, the lynx, the bobcat, for example – while others are probably much
more obscure – the flat-headed cat, the kodkod, the black-footed cat – but
all represent important components of the carnivore guilds found in functional
ecosystems throughout the world.
Small cats are survivors, maintaining low profiles and frequently sharing habitat
with their more massive cousins – the tigers, lions and jaguars – while
dining further down the food chain on small birds, rodents, fish and insects.
Like villagers in India or Africa, small cats don’t necessarily enjoy sharing
their backyards with voracious large carnivores but they somehow manage to coexist
because they have little choice to do otherwise.
Conservation of small cats is
hampered by numerous factors, from ignorance about their very existence to lack
of knowledge about their natural history or status in the wild to indifference
about their survival. Education of the public about small cats is critically
important since awareness and knowledge drive our conservation efforts, raising
concerns about extinction, funding habitat preservation, setting research priorities,
just making people care if ocelots or marbled cats still thrive somewhere out
there, anywhere, in the wild.
So why should you care about the survival of any of these small
cats? Undoubtedly, small cats are extremely charismatic, as
any visitor to the Cincinnati Zoo & Botanical
Garden can attest who has ever looked into the eyes of a Brazilian ocelot or
encountered a baby Pallas’ cat up-close. Our world would be greatly diminished
aesthetically if all the small felids were suddenly gone. Of course, we also
have a moral obligation as humans to not carelessly exterminate the world’s
wildlife species, including small cats, just because we can. If further incentive
is required, small cats also play a vital ecological role in their natural environment,
in some cases as the top predators in their specific ecosystem, such as with
Pallas’ cats in Mongolia or possibly ocelots in southern Brazil. Their
extinction can produce cascade effects downstream on predator-prey density and
relationships that can ultimately collapse the entire ecosystem - to the detriment
of all living things, including us.
Small cats definitely have their place in the wild – the problem is that
so little research has been conducted with these species that we lack definitive
information about their conservation status or what makes them tick biologically.
We often assume that preserving adequate habitat for the big cats (as umbrella
species) will have a trickle down effect in conserving small cats or that small
cats require only minimal habitat sizes so they can persist in more restricted
geographical areas. These assumptions ignore the potentially detrimental impact
of interspecific competition between big and small cats and the habitat specialization
common among small felids. The best places for small cats likely are areas that
lack robust large cat populations so just conserving big cats is not the solution.
Although most small cats may require smaller range sizes than big cats (but see
the Pallas’ cat webpage), ecological specialization of some species, like
fishing cats, restrict them to habitat types, such as wetlands, that are not
widely distributed throughout the species’ geographic range.
How are zoos helping to conserve the small cats? The American Zoo & Aquarium
Association (AZA), comprised of 218 institutions in the United States and Canada,
established its first Species Survival Plans (SSPs) for small cats in 2001. Five
species, the ocelot (Leopardalis pardus), fishing cat (Prionailurus
viverrinus),
Pallas’ cat (Otocolobus manul), black-footed cat (Felis nigripes)
and sand
cat (Felis margarita), are managed by SSPs to improve breeding success
and genetic viability in captivity while striving to protect wild populations
in range countries.
The Cincinnati Zoo is one of the world’s leaders in small cat conservation
through our research efforts at CREW, breeding programs in the Cat House, education
initiatives with small felids and financial support for in situ projects. The
Cincinnati Zoo also is the only AZA-accredited institution that houses all five
of the small cat SSP species. In the small cat pages on the Zoo's website, we
hope
to
educate you and other Zoo members about the extraordinary world of small cats
and some
of
the ongoing efforts of the Zoo to broaden our basic knowledge of small cat biology,
connect captive and wild cat populations and conserve these imperiled small felids
in their natural environment.
What can you do to help conserve small cats? By becoming a CREW member or volunteer,
you
can
help
provide meaningful support to an organization that is working
to conserve small cats, and help contribute to the cat research program.
