For day 7 of #30daymapchallenge on Twitter on the topic of "green", we created a map of Intact Forest Landscapes in South America.
The Intact Forest Landscapes (IFL) data set identifies unbroken expanses of natural ecosystems within the zone of forest extent that show no signs of significant human activity and are large enough that all native biodiversity, including viable populations of wide-ranging species, could be maintained.
You can read more about Intact Forest Landscapes on intactforests.org.
The data comes from intactforests.org/data.ifl.html.
