Freshwater
Shrimp is
only two
inches long.

California Freshwater Shrimp plays a vital role in the aquatic
ecosystems, living in lowland streams and feeding on
decomposing plants. California Freshwater Shrimp are highly
adapted to the environment and employs a number different
techniques to survive. It is nearly transparent. When caught the
shrimp will jab the top of its spine into the roof of the fish’s mouth to
escape. It only gets one chance to reproduce, and doesn’t
produce nearly as many eggs as other species of shrimp do.
Female shrimp swim with her eggs stuck onto her legs in the winter
and spring months so the eggs won’t wash away in a flood. I the
summer, when water levels decrease and water temperatures rise,
the juvenile shrimp will feast on the carcasses of fish that have
suffocated in that environment.
California freshwater shrimp still survive but on private land, and
the population is threatened by landowners.
The degradation of the riparian zone around these streams force
the shrimp to lose their habitat. Keeping aquatic systems in tact
and minimizing the waste of water.

Saber Tooth Tiger

This classic saber tooth tiger
roamed in Western North
America (California) and
South America (Argentina). It
had a short tail, and a huge
pair of teeth on the upper
jaw were serrated along their
back edges, allowing it to
easily pierce the flesh of its
prey more easily. With its
muscular shoulders and
neck, it most likely feed on
slow moving large prey in
which it could sink its large
teeth into.


The Saber Tooth Tiger is
a (K)strategist and has a
low reproductive rate.
And because of the
overhunting of their large
prey there was less food
and the population of the
saber tooth tiger began
to dwindle. And they
could not live without the
source of food. The saber
tooth tiger also had
problems with living in
the new environment.

Purple Star Thistle
This is where it could be found.
This is the Purple Star Thistle

A native of southern Europe, purple star thistle
produces prolific seeds and often invades
floodplains, dry forests and grasslands. This
plant is common in many western states and may
occasionally be found in some Midwestern and
Mid-Atlantic States. The best way to prevent
these invasive species is to recognize the species
before it becomes installed into the habitat. Also
you can revive the site of the land that the plant
is. Since it has no natural predators it wont be
easy to control the way that this species grows.

Florida Wood Stork




The Florida Wood stork indicates if most of the small fish in waters are dying off
from changes in mercury levels to rising temperatures in the water.
Storks are birds of freshwater and estuarine wetlands, primarily nesting in
cypress or mangrove swamps. They feed in freshwater marshes, narrow tidal
creeks, or flooded tidal pools. Particularly attractive feeding sites are
depressions in marshes or swamps where fish become concentrated during
periods of falling water levels.
The generally accepted explanation for the decline of the wood stork is the
reduction in food base (small fish) necessary to support breeding colonies. The
reduction of wetland habitat as well as to changes in water levels from draining
wetlands and changing water flow by constructing levees, canals, and floodgates.
To protect these animals flooding may be necessary to stimulate nesting and
prevent predators from destroying nests. Periodic drying also may be necessary
to prevent trees from dying and to allow recruitment of new trees.

Beavers are keystone species because they benefit
everything around them, even humans.
Beavers produce food for fish and other animals
.Support biodiversity, including 43% of our
endangered species, create vital habitats, preserve
open space, maintain stream and river flow, and
provide greater opportunities for : Wildlife
observation, Hunting and trapping, Fishing, and
Photography. They also lesson erosion, raise the
water table by the building of dams.

The Ptunarra brown butterfly is threatened because its natural habitat is
disappearing. It is a Tasmanian endemic species which means it is only
found in Tasmania. It lives in our native grasslands and grassy woodlands
in the Midlands, and Northwest Plains. Loss of this habitat through land
clearing, grazing by stock and the introduction of exotic pasture grasses
have caused the numbers of butterflies to decline.
“The recovery plan requires good habitat management for this species.
This requires such strategies as deliberate burning of grassland areas to
encourage fresh growth and maintain grassland species diversity whilst
reducing invasion by shrub species. These actions are taking place in
consultation with timber companies, forestry and private land owners.
Areas of grassland have been set aside from plantations to provide
grassland and butterfly conservation. Also in specific areas, plant species
which promote and encourage the Ptunarra brown butterflies are being
planted.”
