Endangered Specie of California
“The Santa Barbara County population of the
California tiger salamander (Ambystoma
californiense) was federally listed as endangered
on September 21, 2000 (65 FR 57242). The
Sonoma County Distinct Population Segment (DPS)
of the California tiger salamander was listed as
endangered on July 22, 2002 (67 FR 47727). The
Central California DPS of the California tiger
salamander was proposed for listing as
threatened on May 23, 2003 (68 FR 28648). The
Santa Barbara and Sonoma County DPSs were
proposed for reclassification from endangered to
threatened, on May 23, 2003 (68 FR 28648). The
California Department of Fish and Game
(Department) considers the California tiger
salamander throughout its entire range to be a
species of special concern (Special Animals List
July 2003
http://www.dfg.ca.gov/whdab/html/lists.html).”
What we can do
Protect their habitat by reducing unnecessary
Sprawling of humans, also reduce the use of
pesticides in Pesticide Reduction Campaign.
Threatened and native to California
Dudleya, Santa Cruz Island
“Dudleya stolonifera is a narrow
endemic found only in six occurrences,
all on northfacing sandstone surfaces
in steep-walled canyons near Laguna
Beach, Orange County, California
(CDFG 1987, p. 1). Three of these
occurrences are on lands managed by
Orange County Parks, two are on
private lands, and one is on land
owned by the City of Laguna Beach
(CNDDB 2010a).
Dudleya stolonifera was listed as
threatened under the California
Endangered Species Act (CESA) in 1987
and as threatened under the Act in
1998.”

Franklin Tree extinct native to the us
•
•
•
Franklinia is a genus of the tea plant
family.
The sole species in this genus is a
flowering tree, Franklinia alatamaha,
commonly called the Franklin tree, and
native to the Altamaha River valley in
Georgia in the southeastern. It has been
extinct in the wild since the early 19th
century, but survives as a cultivated
ornamental tree.
The Franklinia genus differs in having
evergreen foliage, flowers with longer
stems, winged seeds, and conical seed
capsules. (Franklinia was often known as
Gordonia pubescens until the middle of
the 20th century.)

A globally known indicator species is
Indicator Species
•
Native frog populations are plummeting all
over the world there are only observations of
what could be the cause:
•
Destruction of wetlands
•
contamination of water supplies by biocides,
pollutants, and acid rain
•
introduction of non-native predators such as
voracious game fish from hatcheries, as well as
bullfrogs and crawfish that eat the eggs of
native frogs
•
natural population variation
•
fungal disease called Saprolegnia, which has
long plagued hatchery fish and recently spread
to the wild, where it is suspected of affecting
frogs as well as fish
•
depletion of the ozone layer: Now that it is
known that sunbathing sets the stage for skin
cancer, many scientists wonder what the
effects are upon frogs, whose bodies are
protected from the elements by a thin skin
permeable to both water and gas.
•
What we can do: stop the purchasing of frogs
as pets, the eating of frog legs and the use of
pesticides and herbicides, don’t put nonnative
fish in ponds or lakes.

Keystone Species
•
•
•
Scientists have proven that beavers are a Keystone specie
meaning that beavers play a crucial role in biodiversity
many species rely on beaver ponds, many of them
threatened or endangered
•
Therefore, whenever we can coexist with beavers, we are
providing the habitat necessary for supporting many other
species, and protecting the web of life
•
In addition to the very important biodiversity issue, most
people are not aware that there are many other benefits to
beaver ponds
For example
Benefits to us
•
Decrease in floods
•
Recharge drinking water aquifers
•
Remove pollutants from surface and ground water
•
Protection from drought
•
Decreased erosion
Further Benefits
•
Produce food for fish and other animals
•
Support biodiversity (43% of endangered species)
•
Support necessary habitats
•
Maintain stream and river flow

Invasive Species
•
Burmese python is native to Asia
but now found in south Florida.
The release of Burmese pythons in
South Florida is especially
troublesome because the
subtropical climate and the vast
undisturbed habitats of the
Everglades enable the species to
thrive. they have been known to
eat and kill alligators and other
native species to the everglades. To
stop the spreading of these
pythons we can stop the releasing
of them into the wild and raise
awareness of places people can
take them as an alternative to
releasing them from captivity.
