Those who monitor global cover, or have any other interest in global should mask global non-forest areas such as by using resources such as the IUCN Global Ecosystem Typology (iucn.org/resources/conservatio) or the RESOLVE Ecoregions 2017© biomes map (ecoregions.appspot.com/). They are much better than the global / maps that so many use.

Stop large-scale in . are NOT "degraded forests".

Stop mapping global "forests" in terms of vegetation height and woody cover alone. That leads to misclassification of savannas as .

Why is there still an obsessive interest in mapping global forests on the sole basis of remotely sensed vegetation height and woody cover?

For example:

sciencedirect.com/science/arti

tandfonline.com/doi/full/10.10

Such outdated approaches are prone to misclassifying as "forest" or "degraded forest".

It's now known that plant functional traits and other data not easily acquired by satellites must be included.

For example:

spj.science.org/doi/10.34133/2

@wclark

Into "savanna states" or into "savanna-like states"? One assumes that forest and savanna are alternate stable states composed of species with very different functional traits. The other does not.

Savannas and other are not "degraded forests".

Important work.

But the analysis depends on how restoration priority areas are determined, which depends on how ecosystems are defined. Strassburg et al. (2020) is seriously flawed in that regard. Their Extended Data Figs 1 and 5 do not distinguish between "forest" and such as savannas, especially in Africa and South America. This leads to intact savanna areas being misclassified as "degraded forest" and mislabelled as "restoration priority areas".

Excellent review of satellite remote sensing for mapping at regional and global scales.

This is crucial for and the prevention of of such as .

The EU and FAO need to read this, and other recent related work, and then realise they need to update their antiquated definition of "forest" based only on veg structure and ignoring .

This is a great resource for learning about tropical and temperate .

The descriptions and maps of savannas are based on current thinking (not the FAO's outdated definitions that perpetuate the misclassification of savannas as "forest" or "degraded forest").
