OSU study: Bird species losses on remote island in Panama point to lack of habitat connectivity

Losses top 25% as bird population is drying out
CORVALLIS, Ore. (KTVZ) – Free from human disturbance for a century, an inland island in Central America has nevertheless lost more than 25% of its native bird species since its creation as part of the Panama Canal’s construction, and scientists say the losses continue.
The Barro Colorado Island extirpations show how forest fragmentation can reduce biodiversity when patches of remnant habitat lack connectivity, according to a study by researchers at Oregon State University.
Even when large remnants of forest are protected, some species still fail to survive because of subtle environmental changes attributable to fragmentation, and those losses continue over many decades, the scientists say.

program be eliminated by the present funding of only $3 million in the present bill before us. the program partners with the states to protect environmentally sensitive program. it is a partnership program which states are permitted to accomplish this very important goal. it is a vom unitary program that encourages the private owned land and easements without removing the land from private ownership. the easements protect air quality from threatened and endangered species. this particular program is important for the state of hawaii. we have more endangered species per square mile than any other place on the planet, we claim 75% of the endangered plants in the united states. we are the most unique archipelago. a watershed, which was an easement which is strategic watershed. this was done in 2010. this produces the large part of fresh water that contributes to the recharging of the aquifer to the forests and streams that are preserved and sustains the residents of the island.
