Western Swamp
Turtle
Apperance
The western
swamp turtle or short-necked turtle has a flat shell that ranges in color from
brown to black. Its neck is short, and the head is usually held sideways under
the shell. It is Australia's smallest turtle and the male are larger than the
females.
Length
A mature adult Western Swamp Turtle is
approximately l2.5cm.
Habitat
The Western Swamp Tortoise is confined to a very
marginal habitat. Just like the name states they live in swamps when the swamps
are filled with water during the seasons of winter/spring, the tortoises live an
aquatic life. Shallower
pools in the swamps usually begin to dry up in October, and turtles then move
into deeper pools or other refuges; most turtles are in such refuges by
mid-November or early December. With the summer drying out of the ephemeral swamp at Ellen Brook nature
reserve where it occurs, this turtle aestivates in deep cracks and fissures in
the clay.
Eating and
Diet Habits
The Western Swamp Tortoise is carnivorous. When the water
level in the swamp is high it feeds on insects, larvae, tadpoles, small
crustaceans and aquatic earthworms. During its period of aestivation it does not
eat.
Predators
The small
turtle does not have too many predators but is in danger to crodiles and other
predators in the water..Since they are in a very small confined area they are made
easy food for predators such as foxes , feral cats and
dogs
Breeding Habits
Males and females come together for a
brief mating before the female lays her eggs in the swamp bank. There is no
further parental care. Only one lot of three to five
hard-shelled eggs is laid per season. Hatchlings emerge in May or June following
a gestation period of approximately 180 days.
Locations
The
western swamp turtle is now restricted to the Ellen Brook Nature Reserve near
the city of Perth, Western
Australia.
Numbers
Only
35 or so individuals are believed to occur in the wild and is the most
endangered turlte in the
world.
Problems
- It
occurs naturally in a very small area at Ellen Brook NR.
- Currently
the captive population is maintained at one location, the Perth zoo. In the
event of some unforeseen pathogen decimating this group, the recovery program
will be put back years.
- The
husbandry expertise developed during the recovery program is restricted to too
few people. If they should leave the program, a void in experienced people
would occur.
- The
small area of wild habitat and its proximity to Perth cause it to be
continually under pressure from degradation resulting from the ever increasing
development of surrounding areas.
- The Twin Swamps population has become extinct.
- It has been affected by disease and
since it lives in water near the city the water can become polluted easily
from just one dead animal or anything up stream which will come down and if it
does not destory the turtle itself it may kill its
food.
Solutions
- First there needs to be a buffer between any unforeseen
decimation of the captive population.
- A portion of captive bred individuals must be provided to
other interested zoos both in Australia and overseas.
- Any
reintroduction should not be restricted to areas of habitat similar to Ellen
Brook and Twin Swamps, but also include alternative areas of permanent
water.
- Fifty
pairs initially should be made available to private people who can demonstrate
turtle husbandry capabilities by their local or wider contribution in this
area. These could be sold at say $20,000 per pair (a return of one million
dollars), an investment that would guarantee genuine attempts at breeding. At
a later date, depending on the success or otherwise of the private breeders,
an advertising campaign could be implemented promoting the Western swamp
turtle as a 'state of the art' pet: attractive, easily maintained and owners
would be contributing to its conservation.
- A
predator proof fence is all ready in place.
- Elinimate
all the predators where the turtle lives which would not be hard since they
live in a small area.
- Make
water restricted from boats and vechiles.
- Make
huge fines for any littering or dumping waste near the
turtles.
- Test
the water for any pollutents often and act quickly if something
happens.
- Revegetate
the habitat of the Western Swamp Turtle.
- Start up conservation groups to help save this
species.
- Inform the publis about this
species.
