GLAD deforestation alerts update weekly, showing areas of recent lost to forest defenders across the tropics to encourage action.

Fires, pest infestations and stunted tree growth— climate change could have big negative impacts on the forests we know and depend upon.

Tracking tree growth will help us understand whether those trillion trees are growing and whether our efforts to fight climate change are on the right track.

In India, tree cover is on the rise, but primary forests continue to be lost. This piece is part of GFW's Global Insights series.

The world lost 3.8 million hectares of primary rainforest in 2019. How can effective forest policy halt further deforestation?

New data from the University of Maryland (UMD), released on Global Forest Watch, shows that tropical primary forests sustained high losses in 2019. But what does this data show about the causes of loss, and how does it compare to the other estimates of loss out there? Here’s what you need to know about the […]

What is tree cover loss? Tree cover loss is not the same as deforestation. “Tree cover” can refer to trees in plantations as well as natural forests, and “tree cover loss” is the removal of tree canopy due to human or natural causes, including fire. The data presented here do not take tree restoration or […]

Primary forests are some of the densest, wildest and most ecologically significant forests on Earth. They span the globe, from the snow-locked boreal region to the steamy tropics, though 75% of them can be found in just seven countries. But what sets these forests apart from your average backyard woodlands, making them so critical to […]

Forests are crowded places, home to roughly 80% of the world’s terrestrial biodiversity, with millions of species competing with and depending on each other for survival. This incredible biodiversity is often one of the key reasons for protecting forests— to preserve the vast variety of life on Earth. But just what is biodiversity anyway, scientifically-speaking? How do biologists […]
