Humans have altered, degraded, and destroyed habitat in many different ways. Logging around the world has destroyed forests that are habitat to many species. More than a fifth of the planet’s bird species face extinction as humans venture further into their habitats and introduce alien predators.
The main factors that cause species to become endangered are habitat destruction, invasive species, pollution, and over exploitation. No doubt there have been success stories of the species that have reappeared but the overall situation of the world’s birds is worsening.
Which are the nation’s most threatened bird habitats?
U.S is on the top of the list. Open ocean and bird nesting islands including Hawaii territory come next .Sagebrush areas in Western States (Washington, Oregon, Montana) come at the third position. On the fourth is the Edwards Plateau Savannah of Texas.
Before the arrival of humans in archipelago there were 140 native breeding species and subspecies out of which more than half are extinct. Despite the efforts of the government agencies and private organizations, the threat to birds’ habitat in Hawaii continues.
Michael Parr, vice president of the Washington-based American Bird Conservancy said:
It isn’t that government agencies aren’t doing what they should about saving habitats and birds, but more money is needed to make those efforts a success.
Government agencies are doing a lot about saving habitats and birds but more money is needed to make the efforts a success moreover the expectations should be kept realistic.
Lot of efforts is to be done which include:
Partnerships with private landowners to conserve habitat: a system of natural area reserves; projects to fence off areas from invasive species, such as goats, that destroy native plants, and a recovery plan for forest birds.
