Endangered specie is a species whose
population is so low that the species is at
risk of going extinct.
5 of the most common reasons for
endangerment are habitat loss,
pollution, competition from other
species, disease, and predation.
Protect animals habitats
Give the animals space to live
Recycle, reduce, and reuse
Control introduced plants and animals in
an area
Plant plants that are native to the area
Indian bat- human disturbance
Northern flying squirrel- deforestation
Dickcissel- human development
American waterwort- competition from
invasive wetland species
Appalachian oakfern- deforestation
Invasive species are non-native species
that take over an area that was all ready
inhabited by native species
Introduced species are non-native
species that come into an area by
human activity deliberate or some times
accidental
Native species are species that are in an
area for natural reasons
They can hitch rides on ships
They can be in wood products
They can be in ornamental plants
They could be in the pet trade
Some get smuggled illegally into the US
They can carry diseases
They can change the food webs
They can decrease biodiversity
Some can even effect the soil that they
live on
Sea lamprey, Petromyzon marinus, originated
in Lake Ontario, it’s niche in both it’s natural
and introduced environments are as a
parasite, it cause other fish to die.
Asian Clam, Mollusks-Bivalves, originated in
Asia, it’s niche in both it’s natural and
introduced environments are as a food source
for other animals, it decreases biodiversity.
Red-eared slider, Trachemys scripta elegans, it
is native to the southern united states, it’s niche
is to be a predator and a prey in its natural and
introduced environments, it is out competing
the native western pond turtle.
Hydrilla, Hydrilla Verticillata, no one is
exactly sure where it originated but people
think Asia, it’s niche in both it’s natural and
introduced environments are to shade the
species under the water, This is making it
hard for fish to get sunlight.
Purple Loosestrife, Lythrum Salicaria, is
native to Europe, it’s niches are to feed
certain beetles in it’s natural and
introduced environments, it doesn’t give
the native plants places to grow.
Reintroduced species are species that
got put back into the wild in an area
that they formerly lived in.
Extirpated species are species that do
not exist in the wild in one area but can
be found elsewhere in the world.
The river otter was reintroduced into PA
in 1982. The otters were captured by the
method of live trapping
75 otters were reintroduced into PA
