The canopy surface and stand development: assessing forest canopy structure and complexity with near-surface altimetry
A first-return laser rangefinder deployed from a low-flying helicopter provided inexpensive, repeatable, and high-resolution measurements of the shape of the outer forest canopy in stands of four successional stages on the Maryland coastal plain. The traces of canopy height in these stands revealed structural characteristics such as cover, maximum and mean heights which were consistent with cor...
متن کاملForest Stand Structure and Development: Implications for Forest Management
A general premise of forest managers is that modern silviculture should be based, in large part, on natural disturbance patterns and species' adaptations to these disturbances. An understanding of forest stand dynamics is therefore a prerequisite to sound forest management. This paper provides a brief overview of forest stand development, stand structures, and disturbance regimes and discusses ...

متن کاملSimulating Ozone Effects on Forest Productivity: Interactions among Leaf-, Canopy-, and Stand-level Processes
Ozone pollution in the lower atmosphere is known to have adverse effects on forest vegetation, but the degree to which mature forests are impacted has been very difficult to assess directly. In this study, we combined leaf-level ozone response data from independent ozone fumigation studies with a forest ecosystem model in order simulate the effects of ambient ozone on mature hardwood forests. R...
متن کاملPercent Canopy Cover and Stand Structure Statistics from the Forest Vegetation Simulator
He has been an active participant in the development of the Forest Vegetation Simulator and its extensions since 1978. Estimates of percent canopy cover generated by the Forest Vegetation Simulator (FVS) are corrected for crown overlap using an equation presented in this paper. A comparison of the new cover estimate to some others is provided. The cover estimate is one of several describing sta...
