This in turn has resulted in reduction in no. This occurs on land in the form of overhunting, excessive logging, poor soil conservation in agriculture and the illegal wildlife trade. Replanting of trees in a forest is a slow and expensive process but it is very important part of conservation. Forest management :- Conservation of trees can be done by replacing trees that are cut regularly. Preventing overgrazing :- Grazing animals eat or trample young trees , destroy leaves on lower branches and injure roots and trunks.

Preventing forest fires:- A forest fire destroys standing timber and consumes the seeds and young trees of the future forests. Lightning is a natural cause of forests fires. The increasing human pressure on wildlife has led to the extinction or disappearance of some of the species. This pressure is in the following form:The destruction of habitats by deforestation to make houses or farmlands.


The overexploitation of animals species for commercial use, such as the selling of the skins of leopards, cheetahs and tigers. Even their teeth and claws are sold. Red Data Book species are classified into different categories of perceived risk. Each Red Data Book usually deals with a specific group of animals or plants. They are plants and animals that exist in small numbers that may be lost forever if we do not take quick action to stop their decline. If we cherish these species, like we do other rare and beautiful objects, these living organisms become treasures of the highest magnitude.

OR An extinct species is a species that has completely disappeared from the planet i. The term could refer to an animal, a plant, a fungus, or even a micro-organism.

Reasons Why We Need to Save Wildlife

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. A wide range of pollutants negatively impact wildlife health. For some pollutants, simple exposure is enough to do damage e. For others, its through inhaling e. Pollutants affect different species in different ways so a pollutant that is bad for one might not affect another.

Present day climate change is a man-made phenomenon currently changing Earth's environmental conditions.

It's related to some of the aforementioned threats to wildlife like habitat destruction and pollution. Rising temperatures, melting ice sheets, changes in precipitation patterns, severe droughts , more frequent heat waves , storm intensification, and rising sea levels are some of the effects of climate change. Meanwhile, a warming climate, fluctuating precipitation, and changing weather patterns will impact species ranges. Overall, the effects of climate change increase stress on ecosystems, and species unable to cope with rapidly changing conditions will go extinct. It's estimated that, because of human activities, current species extinction rates are about times greater than the background extinction rate the 'normal' extinction rate that occurs without additional influence.

A UN report assessing global biodiversity extrapolated IUCN data to all species and estimated that 1 million species worldwide could face extinction. Deciding which species to conserve is a function of how close to extinction a species is, whether the species is crucial to the ecosystem it resides in, and how much we care about it.

The leatherback sea turtle Dermochelys coriacea is the largest turtle in the world, is the only turtle without a hard shell, and is endangered. The leatherback sea turtle faces numerous threats including being caught as bycatch , harvest of its eggs, loss of nesting habitats, and marine pollution. Habitat conservation is the practice of protecting a habitat in order to protect the species within it.

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.

Wildlife conservation

Habitat conservation is usually carried out by setting aside protected areas like national parks or nature reserves. Even when an area isn't made into a park or reserve, it can still be monitored and maintained. The red-cockaded woodpecker Picoides borealis is an endangered bird in the southeastern US.

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. In an effort to increase woodpecker numbers, artificial cavities essentially birdhouses planted within tree trunks were installed to give woodpeckers a place to live.

An active effort is made by the US military and workers to maintain this rare habitat used by red-cockaded woodpeckers. Conservation genetics studies genetic phenomena that impact the conservation of a species. Most conservation efforts focus on ensuring population growth but genetic diversity also greatly affect species survival.

High genetic diversity increases survival because it means greater capacity to adapt to future environmental changes. Though not always the case, certain species are under threat because they have very low genetic diversity. As such, the best conservation action would be to restore their genetic diversity. The Florida panther is a subspecies of puma specifically Puma concolor coryi that resides in the state of Florida and is currently endangered. In the early s, only a single population with individuals were left. The population had very low genetic diversity, was highly inbred, and suffered from several genetic issues including kinked tails, cardiac defects, and low fertility.

The goal was to increase genetic diversity by introducing genes from a different, unrelated puma population. By , the Florida panther population had tripled and offspring between Florida and Texas individuals had higher fertility and less genetic problems.

In , the US Fish and Wildlife Service estimated there were adult Florida panthers and in , there were signs that the population's range was expanding within Florida. According to the National Wildlife Federation, wildlife conservation in the US gets a majority of its funding through appropriations from the federal budget, annual federal and state grants, and financial efforts from programs such as the Conservation Reserve Program , Wetlands Reserve Program and Wildlife Habitat Incentives Program.

In the late s, as the public became dissatisfied with government environmental conservation efforts, people began supporting private sector conservation efforts which included several non-governmental organizations NGOs. Many NGOs exist to actively promote, or be involved with, wildlife conservation:. From Wikipedia, the free encyclopedia. Main article: Leatherback sea turtle. Main article: Red-cockaded woodpecker.
