The study quantified the dynamics of native forest cover in Brazil's Atlantic Forest from 1990 to 2017, revealing a stable overall forest cover but with ongoing loss of older forests hidden by increased cover of younger forests. The changes have led to increased forest isolation in 36.4% of landscapes, while the clearance of older forests associated with the recut of younger forests has resulted in a progressive rejuvenation of native forest cover. The inclusion of native forest spatiotemporal dynamics in restoration programs is emphasized to better estimate both expected benefits and unexpected problems.
Understanding the dynamics of native forest loss and gain is critical for biodiversity conservation and ecosystem services, especially in regions experiencing intense forest transformations. We quantified native forest cover dynamics on an annual basis from 1990 to 2017 in Brazil's Atlantic Forest. Despite the relative stability of native forest cover during this period (similar to 28 Mha), the ongoing loss of older native forests, mostly on flatter terrains, have been hidden by the increasing gain of younger native forest cover, mostly on marginal lands for mechanized agriculture. Changes in native forest cover and its spatial distribution increased forest isolation in 36.4% of the landscapes. The clearance of older forests associated with the recut of 27% of younger forests has resulted in a progressive rejuvenation of the native forest cover. We highlight the need to include native forest spatiotemporal dynamics into restoration programs to better estimate their expected benefits and unexpected problems.
