Varied motivations for secondary forest reclearing among landholders make forest persistence challenging

open access: yesPeople and Nature, EarlyView.
Abstract Remote sensing studies show that ephemeral forest regeneration is widespread in the tropics, limiting the climate and biodiversity benefits from net increases in forest cover. Socioeconomic, biophysical and landscape variables can help explain the spatial distribution of reforestation reversals.
