Abstract

© 2018 Society for Ecological Restoration Recent land cover analysis reveals significant forest recovery around the world, suggesting that some countries may be in a forest transition. However, remotely sensed imagery does not reveal the driving causes of forest recovery, which may be due to active reforestation efforts or natural successional processes (passive reforestation). We aimed to distinguish these two processes in the priority temperate forests surrounding the Monarch Butterfly Biosphere Reserve (342,773 ha) in central Mexico. We combine an analysis of remotely sensed imagery with field interviews (n = 43) to examine the mechanisms and drivers of observed forest recovery. Our analysis of the satellite imagery revealed a net increase of 3,798 ha of forest between 1986 and 2012, yet the rate of recovery is slowing. Our interview data revealed that the vast majority of the recovered forests are the result of natural regrowth (passive reforestation), and most of this regrowth is observed on previously degraded forest lands. We estimate that between 58 and 429 ha have been recovered from active reforestation efforts in the 1986–2012 period. We find that reduced logging and grazing pressures are important drivers of forest recovery, while agricultural abandonment may be less influential than often believed. Our results suggest that reforestation investments might be wisely spent supporting and maintaining the natural resilience of forests rather than on costly reforestation programs.
