Impact of land-use on savanna vegetation and populations of non-timber forest product-providing tree species in West Africa [PDF]
, 2011 Savannas are the most important timber and non-timber forest products (NTFPs) providing ecosystems in West Africa. They have been shaped by traditional human land-use (i.e. agriculture, grazing, and harvesting) for thousands of years. In the last decades,

PLANTS, PEOPLE, PLANET, EarlyView.Fonio (Digitaria exilis and Digitaria iburua) cereals are valued for their drought resilience, adaptability to poor soils, and cultural importance. In Nigeria, where both species are cultivated, fonio has declined due to labor‐intensive processing, lower yields, and changing livelihood choices. By documenting 21 landraces (15 D. exilis and 6 D. iburua),

Niche‐tracking as a collecting method: Habitat‐targeted search strategies for taxon‐focused botany
PLANTS, PEOPLE, PLANET, EarlyView.Biodiversity science depends on more than collecting plants—it depends on how we search for them. Although GPS and digital maps have transformed fieldwork, they can also encourage repeated visits to the same easy‐to‐access sites, leaving other habitats and populations unknown to science.

Remote Sensing in Ecology and Conservation, EarlyView.Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...

Grass Species Flammability, Not Biomass, Drives Changes in Fire Behavior at Tropical Forest-Savanna Transitions [PDF]
, 2018 Forest-savanna mosaics are maintained by fire-mediated positive feedbacks; whereby forest is fire suppressive and savanna is fire promoting. Forest-savanna transitions therefore represent the interface of opposing fire regimes.
