An endangered species is a species of organisms facing a very high risk of

extinction. The phrase is used vaguelly in common parlance for any species fitting this description, but its use by

conservation biologists typically refers to those deigned Endangered in the IUCN Red List, where it is the second

most severe conservation status for wild populations.

There Are Currently 3070 animals,

And 2655 plants classified as endangered worldwide,

Compared with 1998 levels of 1102 and 1197, respectively.

To prevent the extinction of species need to know their environment and

learn to live with it unchanged, avoiding sudden changes in the environment and prevent the

disappearance of some species, living things need to adapt to changes in

their environment for long periods of time, if the changes are aburt and no

adapt perish as a species.

CausesSpecies are extinct or have reduce populations

for several reasons, but the main cause is: Habitat destruction due to human Habitat destruction due to human activities.activities.

• As they envolve different species, most of wich are adapted to specific habitat or environment that best meets their needs for survival.

• Human activities as pollution, deforestation, destruction of coral reefs, etc...

• Habitat fragmentation, isolation and division of habitats into smaler areas, have led to

speciers of plants and animals kept in these “islands” of habitat lose contact with others

of their own kind.

Sometimes fragmented habitats become so small that they can maintain a sustainable

population.

Consequences Upon termination of a species is altered

throughtout an entire ecosystem, and this results in a lack of balance in the proliferation of other species still exist, whether plants, animal or both, to be affected the ecosystem is also affected being human and planet as such, not only living things.

The conservation status of a species is an indicator of the likelihood of that endangered species becoming extinct. Many factors are taken into account when assessing the conservation status of a species, including statistics such as the number remaining, the overall increase or decrease in the population over time, breeding success rates, known threats, and so on. The IUCN Red List of Threatened Species is the best-known worldwide conservation status listing and ranking system.

It has been estimated that over 40% of all living species on Earth are at risk of going extinct. Internationally, 199 countries have signed an accord agreeing to create Biodiversity Action Plans to protect endangered and other threatened species. In the United States this plan is usually called a species Recovery Plan.

Endemic Species• Endemic species constitute 40% of the flora of

the island. In this group we pine (Pinus occidentalis), royal palm (Roystonea hispaniolana), palm or coconut catey macaque (Bactris plumeriana) and guano (Coccothrinax montana).

Native species• The species of this group are corn pineapple,

guaiacum, ceiba, mahogany (national tree), the guava, the guayiga, soursop and snuff.
