Species
Grace Whitworth
 Enlisted
as an Endangered Specie in 1998
 Only comes out during the hot summer months of
California; spends remainder of time underground
 Listed as “Endangered” due to the threat of
mining in the Elisnore Mountain Range of
California and the loss of habitat from human
development
 The population has risen in recent years because
California has set aside more protected land for
natural habitat development. If this trend were to
continue, then the Munz’s Onion species could
again thrive

Lives in Old Growth Forests of North America (Northern
California, Pacific Northwest, South Canada).
Identified by large brown and white stripes on the large body;
is one of the largest types of owls in North America.
The population of the Spotted Owl directly correlates with the
population of tree species in Old Growth forests; this is the best
explanation of the Indicator species role the Spotted Owl
plays.
The Spotted Owl is most likely to be affected by global climate
change from deforestation of Old Growth forests. The most
crucial step is to prevent habitat fragmentation and
destruction from deforestation. This may be by finding
alternates to paper products or using tree farms with more
biodiversity instead of logging in Old-Growth areas.

Original range was in Eurasia; now plagues freshwater
waterways of US
Were introduced as escapees or intentionally introduced for
breeding in aquaculture c. 1830’s
Are considered invasive because they feed on Benthic and
photosynthetic zooplankton in freshwater systems and
compete with native fish species. Can also tolerate both fresh
and brackish water.
Scientists are trying to naturally rid the carp from freshwater
areas so as not to disturb the natural conditions of sensitive
native animals.
One method of control suggested is use of pheromones, or
hormones which trigger certain responses, which repel the
carp out of an area but have no effect on native species.

Dependent on Old Growth forests for its habitat.
Logging destroys its natural habitat and specific niche in
Old Growth forests. Can be affected by hunting
They are considered a keystone species because their
nests are used by many other birds and small mammals in
Old Growth forests as well as reptiles and amphibians
along riparian zones, which the bird is known to occupy.
Conservation methods include abstaining from forestry of
Old Growth Habitats, hunting laws forbidding the hunting
of the species, and abstaining from the use of monoculture
forestry (the woodpecker depends on a variety of trees,
none of which are used in monoculture.)

A small herb that grows in mainly along the Pacific Coast
in sandy or gravelly soils of granite rock.
Threatened by: cattle trampling (which causes soil
compaction, erosion, and degradation), the planting of
non-native vegetation that occupies the habitat of the
pussypaws, and acid deposition from fuel, which the
pussypaws may not tolerate due to its sensitivity to its
environment.
One management tactic was to fence in certain areas
so cattle and livestock could not trample the plant. Other
possible management techniqus include increased
monitoring and awareness which thus far, have not been
granted to the pussypaws mariposa.
