Land-cover changes during the past 50 years in the semi-arid tropical forest region of northern Peru

Abstract: Dry forests are under much higher pressure from deforestation than humid forests, yet less attention has been paid to these forests. To develop better management strategies, it is necessary to analyse the dynamics of these forests at different scales and to assess their potential to recover from natural or human disturbances. This study combines broad and fine scales to investigate temporal changes: at broad scale we use aerial photos (from 1949, 1962, and 1999) and GIS to document land-cover change during a long-term period of 50 years; at fine scale we use spatial gradient analyses to document changes in species composition during a short-term period of four years. Re-sampling of the same elevational gradient (100–460 m a.s.l.) provides both a spatial and temporal gradient. Plausible causal links between human impact and documented changes are evaluated by means of ordination and Monte Carlo permutation tests. Density and diversity of seedlings, juveniles, shrubs, and trees were .... https://www.erdkunde.uni-bonn.de/article/view/2700
