The webinar by Land & Carbon Lab on 18th July on mapping the world's trees should be interesting, especially for those doing #SavannaScience who know that tree height and cover are not sufficient metrics for defining forests. #SavannasMatter

The authors provide evidence that vegetation changes in SE Asia during the Last Glacial Maximum involved "fluid" transitions between lowland rainforest, seasonally dry forest and tropical montane forest, not switches between forest and savanna. However, their depiction of the alternative stable state model of forests and savannas is flawed. It doesn't consider recent insights and is based on erroneous interpretation of earlier studies in #SavannaScience.

Excellent review of large herbivore impacts.

The worst ever map of global #forest cover is in Fig 1 of this paper:

There is interesting circularity in the use of global forest/non-forest (FNF) and global forest change (GFC) products. FNF maps are used to mask non-forest areas in studies of global forest change, and GFC maps are used to update FNF maps, yet both types of map are almost always based only on vegetation structure (height or tree cover). The situation is analogous to using the wrong screwdriver on a screw that will never tighten, even with the correct screwdriver.

I don't, but I'm interested to know if you find out.

Almost everyone who is anyone in #SavannaScience attends the Savanna Science Network Meeting in Skukuza, Kruger National Park.

I'll be posting updates from this year's meeting, which is the 20th edition.

Great piece of #SavannaScience work by Corli Wigley-Coetsee and others showing factors other than large mammal herbivory, such as dispersal limitation, seed predation, or drought, may limit woody plant populations and communities in semi-arid #TropicalGrassyBiomes.
