Today, it is a rare habitat (as fires have become rare and many pine forests have been cut down for agriculture) and is commonly found on land occupied by US military bases, where pine forests are kept for military training purposes and occasional bombings (also for training) set fires that maintain pine savannas.
Moreover, destruction and fragmentation create smaller habitats.
Smaller habitats support smaller populations, and smaller populations are more likely to go extinct.
Examples of habitat loss include deforestation, agricultural expansion, and urbanization.
Habitat destruction and fragmentation affect wildlife because the resources available to wildlife are reduced.
This is sometimes preferable to focusing on a single species especially if the species in question has very specific habitat requirements or lives in a habitat with many other endangered species.
The latter is often true of species living in biodiversity hotspots, which are areas of the world with an exceptionally high concentration of endemic species (species found nowhere else in the world).A 2019 UN report assessing global biodiversity extrapolated IUCN data to all species and estimated that 1 million species worldwide could face extinction.Yet, because resources are limited, sometimes it's not possible to give all species that need conservation due consideration.Main article: Culling Culling is the deliberate and selective killing of wildlife by governments for various purposes.An example of this is shark culling, in which "shark control" programs in Queensland and New South Wales (in Australia) have killed thousands of sharks, as well as turtles, dolphins, whales, and other marine life.Overexploitation is the harvesting of animals and plants at a rate that's faster than the species's ability to recover.While often associated with overfishing, overexploitation can apply to many groups including mammals, birds, amphibians, reptiles, and plants. Pollutants affect different species in different ways so a pollutant that is bad for one might not affect another., because of human activities, current species extinction rates are about 1000 times greater than the background extinction rate (the 'normal' extinction rate that occurs without additional influence) .However, because not all species have been assessed, these numbers could be even higher.The leatherback sea turtle faces numerous threats including being caught as bycatch, harvest of its eggs, loss of nesting habitats, and marine pollution.In the US where the leatherback is listed under the Endangered Species Act, measures to protect it include reducing bycatch captures through fishing gear modifications, monitoring and protecting its habitat (both nesting beaches and in the ocean), and reducing damage from marine pollution.
