How do #Deforestation frontiers relate with #Conservation priorities, and different forms of protection in #TropicalDryWoodlands worldwide?

A thread on our paper "Tropical dry woodland loss occurs disproportionately in areas of highest conservation value" led by Ana Buchadas, with @TobiasKuemmerle @BiogeoBerlin https://dx.doi.org/10.1111/gcb.16832
(thread written by Ana for Twixxxx, reformulated here for the greater good)

We found that global #Conservation priorities were overrepresented in tropical dry woodlands, yet ~ 40% of all dry woodlands were under some form of #Deforestation frontiers.

Such deforestation frontiers were overrepresented in #conservation priority areas threatening the #Biodiversity and carbon rich areas of world’s tropical dry woodlands, yet the pattern of deforestation differs across geographies meaning different impacts levels

We also show that #IndigenousPeople s’ lands and #ProtectedAreas showed lower proportion of deforestation frontier than other areas, and thus remain important areas to support in protecting these ecosystems

By understanding #deforestationpatterns and the interaction with protected areas and #IPLs, we can better understand how to tailor conservation strategies and support these unique #SocioEcologicalSystems.

@pmeyfroidt Thx for sharing as someone that does not do research on this topics I find this interesting and noted the switch to "forest loss" to "deforestation frontiers"

> Much woodland loss is concentrated in deforestation frontiers, places where woodland loss is progressively expanding, typically translating into rapid or sustained processes of tree loss

@defuneste Thanks!,
technically, the raw data used measure "tree cover loss", which can correspond to various processes including e.g. harvesting planted trees in plantations rotations. We move to "Forest" or "woodland" loss when aggregating to larger grid cells.
Deforestation frontiers are more specific, as areas with large and fast forest/woodland loss that is not part of management rotations, typically due to agricultural expansion.
