Global Forest Map


A gorgeous new tool for assessing gain and loss in global forests was released this week by University of Maryland researchers, the result of a five year, broad-based collaborative project. The interactive map of Global Forest Change is powered by Google’s computing cloud will offer a means to establish forestry baselines around the world, with a great amount of detail.

This excellent article quotes the project’s lead author Matthew Hansen on the map and accompanying study (published in Science): “This is the first map of forest change that is globally consistent and locally relevant. Losses or gains in forest cover shape many important aspects of an ecosystem including, climate regulation, carbon storage, biodiversity and water supplies, but until now there has not been a way to get detailed, accurate, satellite-based and readily available data on forest cover change from local to global scales.”

It didn’t surprise me that Brazil and Indonesia are among the top five countries with the highest level of deforestation since 2000. The policies of those countries favor development of heavily forested, biodiverse areas.

As an Indonesian palm oil representative once told me, we shouldn’t worry about the loss of rainforest because it was mostly all cut down already, anyway. In its place, palm oil plantations. “Trees are trees, so we have offset deforestation with sustainable new forests.”

The new Global Forest Change tool accounts for this as well, with layered levels of data allowing users to see whether the forests in question are old growth, diverse habitats, or newer second-growth utility forests.

It did come as a surprise that Russia has lost more forest than any other nation, and that the top five are rounded out by the United States and Canada.

From, “Improved understanding of the state of forests through tools like these should boost the ability of decision makers — from lawmakers to business leaders — to establish policies that better protect forests.”
