Spatial and temporal patterns of recent forest encroachment in montane grasslands of the Valles Caldera, New Mexico, USA

Jonathan D. Coop, Thomas J. Givnish


Summary - what did the authors do and why?

The authors quantitatively assessed the spatial and temporal patterns of tree invasion into montane and subalpine grasslands in northern New Mexico. They further assessed the effects of topography, climate, and land use practices on these changes in grassland structure over time.


Publication findings:

The authors found that the interruption of frequent fire in the late 19th century was the main cause of tree invasion on upper mountain slopes and mountain tops within the region.
