Down about 85% from their levels around 130 years ago, according to researchers from the US, China, Italy, Uruguay, and Australia, the decimation of native oysters — a contributor to healthy ecosystems and an indicator of ecosystem health — has largely been caused by overharvesting, disease, and introduction of exotic species.

A US Forest Service report indicates 4,600+ threatened species live in more than 90% of the country’s watersheds, discusses problems as well as a number of plausible solutions, and includes several maps that allow you to quickly determine if at-risk species are in your audience area.
Two recent studies — one examining problems in urban and natural forests, and the other on microbial pests in various settings — reveal the latest knowledge on insect and microscopic invasive species.

The timing of a U.S. Fish and Wildlife Service decision to propose listing of the greater sage-grouse as a threatened or endangered species is coinciding with the presidential election and the rapid expansion of the influential oil and gas industry.
This invasive grass that already has a grip on about 2 million acres in the West makes the rangeland it invades virtually worthless for grazing, harms many animals that contact it or try to eat it, increases wildfire risk, and creates monocultures that have very low biodiversity and crowd out numerous native plant and animal species.
The map and report on known greater sage grouse high-density breeding populations is a starting point that can be refined with the input of state fish and wildlife agencies. But you can use it right away as you cover various land use and environmental issues.Region:
Land owners signed up to protect 272,762 acres, which in one year adds about 12% of the total acreage covered during the 15-year history of the voluntary Wetlands Reserve Program. Funding for the 1,414 contracts totaled $592,562,106.
