Hydrology Paper of the Day @bkshriver.bsky.social on why woody plants are apparently more prevalent in dryland areas: long-term increases in tree population are responsible for more young trees, and low rates of tree establishment over the past 400 years in the Great Basin and Colorado Plateau.

Bob Shriver @bkshriver.bsky.social · May 1

Why has woody plant density been increasing in dryland ecosystems? In a new paper in @pnas.org we show that increasing tree density in pinyon-juniper woodlands could largely be a result of long-term population growth, rather than recent anthropogenic effects. www.pnas.org/doi/10.1073/...
