Protected areas don’t always protect as well as they should, study reveals
Conservation projects often hinge on areas of land being given protection, but little is known about how well many protected areas actually do their job. Studying four of the world’s major moist tropical forests, a group of Duke University researchers led by Stuart Pimm found that inaccessibility can be a tree’s best friend. Protected areas within the Amazon and Congo forests, for example, nestle within largely well-forested surrounding areas, which keeps them relatively safe. The Atlantic Coast and West African protected areas, by contrast, are more fragmented: unfortunate, given their status as biodiversity hotspots. The study, published this week in PNAS, nonetheless throws welcome light on the way that large scale conservation initiatives work, or don’t.
