Wildlife populations decline in Kenya’s national parks

Tuesday, July 21st, 2009

This study represents the first time, researchers looked at population changes within a national park system relative to all of the wildlife populations across the whole country. “And we found that wildlife populations inside and outside of the parks are declining at much the same rate,” according to David Western, an adjunct professor of biology at University of California, San Diego and the founding executive director of the African Conservation Center in Nairobi, who headed the study published in the July 8 issue of the journal PLoS One.

Ecosystems respond well to restoration

Friday, July 17th, 2009

Surveying 240 studies, scientists at the Yale School of Forestry & Environmental Studies found that the speed of recovery depended upon the type of ecosystem and the growth rate of the organisms within it. Forests recovered within 42 years, but ocean floors in less than a decade. Polluted ecosystems – those plagued by oil spills, mining, trawling, or invasive species – could recover in just five years. Only 15 percent were deemed beyond recovery.

Uganda likely to lose all forest cover in 50 yrs

Forests and tree planting can help mitigate the effects of global warming by increasing carbon storage and cutting greenhouse gas emissions, experts say. Tropical deforestation accounts for a fifth of emissions from human activities.
