Wolf Reintroductions

Wolves were once the most widely distributed mammals on the planet. With its excellent adaptability, wolves occupy almost all habitats except the tropical jungle. However, with the advent of humans, the number of wolves has decreased. The eradication program of this system covers the largest predators and eliminated wolves by population invasion, overpopulation of prey populations, and loss of habitat by the 1940's. In 1973, the wolf was finally protected by the Endangered Species Protection Act, and recently the number of wolves has increased due to the recovery and reintroduction of wolves.

Indeed local industry and environmental groups have struggled with Yellowstone and Idaho for reintroducing wolves for decades. The idea of ​​reintroducing wolves was first submitted to Congress by biologists in 1966. These biologists were concerned about the extremely high elk population of Yellowstone and the ecological destruction of excessively large land. According to official statistics, the year 1926 was the year when the last wolf was murdered at the Yellowstone border. When the wolves were eradicated and hunting was eliminated, the elk population prospered. In the coming decades, the number of elk populations has become very large, and the balance of the local ecosystem has been lost. The number of elk and other large prey increased to the extent that they gathered at the bottom of the valley and overgrazed the newly grown vegetation. Due to overgrazing, deciduous woody plant species such as Highland poplar and Kawanagi poplar are drastically decreasing. This change also affected other species.

Umbrella seeds wolves and other ultramarine animals can successfully control prey populations (such as umbrellas). Have you heard about the influence of Yellowstone reintroducing the wolf? The number of deer will decrease. Then grass and trees are higher and create new habitat for insects. Due to the presence of wolves, park biodiversity has increased. After obtaining these data, ecologists will analyze them. They use the index to evaluate the similarity of plants and animal communities, such as Shannon and Evenness indexes. They use maps to associate habitat quality with spatial distribution of species. They also examined the rarity of the habitat and the specificity of the species. They studied vulnerability of species carefully as to whether they were on the red list or whether they were sensitive to interference.

Reintroduction of wolves involves the rebuilding of some of the gray wolves in the area where local wolves are extinct. Re-introduction only takes into account that a large area of ​​appropriate wilderness is still present, and certain bait species are rich enough to support the intended wolves. According to the agreement between the United States and Mexico to rescue highly endangered variants, the last five wild wild gray wolves were captured in 1980. Between 1982 and 1998, a comprehensive breeding breeding program restored the Mexican wolves from extinction crisis. More than 300 captured Mexican wolves are part of the recovery plan
