Historical deforestation in Madagascar may not be as bad as commonly believed
The long-held assumption that Madagascar has lost 90 percent of its forest cover due to fire and slash-and-burn agriculture may be overstated, argues new research published in Conservation Letters. Analyzing 6000-year pollen records in four sites, Malika Virah-Sawmy of Oxford University found evidence that vegetation in southeast Madagascar has for millennia been a mosaic of forests, woodlands and savannas, rather than continuous forests as generally believed. "Dry woodlands were once connected to humid forests in southeast Madagascar but disappeared in response to extreme dryness over the last 6000 years," Virah-Sawmy told mongabay.com. "By contrast, the humid forests were more resilient to these climatic shifts. Thus the current distribution of forest types in Madagascar may well be a function of climate change, rather than necessarily the product of human activities." Virah-Sawmy nonetheless notes that deforestation on the California-sized island has been extensi...
