While much research has pointed to a steady decline of the Sumatran orangutan as a consequence of habitat loss, a recent study shows population estimates are higher than previously thought. Are these higher estimates enough to preserve the species?
While lion populations in West, Central, and East Africa have all been declining at alarming rates, one study finds that lion populations in fenced reserves, specifically in South Africa, have actually been on the rise.
A new technique to improve conservation programs, known as participatory monitoring, involves collaboration between citizens, government, NGOs, and researchers to assess environmental issues. Since researchers alone might not have enough time or funding to collect adequate long term data, educating and training local people may prove to have more long term potential for conservation goals.
Tropical forests are being lost due to timber harvest and cultivation, and ecosystems are being threatened by the spread of exotic and invasive species that outcompetes native ones. A recent study shows how an exotic plant species can be beneficial in connecting forest fragments, which promotes healthy wildlife populations.
