Forest Assessment and Observation,s and remote-sensing data collected by FAO together with regional partners. These reports provide rough estimates about changes in forest areas. Detailed descriptions of the structure and species composition of the world’s forest ecosystems that are based on high-resolution sensors and large networks of field plots are also beginning to emerge.

Forest Assessment and Observation,ning forest ecosystems. Specific issues of forest assessment (a brief reference to the nested plot design and to the sampling of low woody vegetation) are included here, but the main focus of this section is on continuous observation of the biological and structural dynamics of forest ecosystems by

Forest Production,and models of forest production. Harvest events that cause abrupt modifications in the distribution of temperature and radiation with associated changes in competition, growth, soil processes, and habitat availability are among the most important ecological disturbances. Modeling harvest events is t
