Seedling morphology of 210 species (173 trees and 37 lianas) was studied from a community perspective to identify major patterns of seedling functional types in a Mexican rain forest. Five types of seedlings were distinguished: cryptocotylar with reserve storage or absorption cotyledons (epigeal [CER] and hypogeal [CHR]), phanerocotylar epigeal, either with photosynthetic cotyledons (PEF) or wi...

In a context of risk of forest fire, the development of actions concerning wildfire prevention and land management is necessary and essential particularly in wildland urban interfaces (WUI). The term ‘WUI’ always includes components such as human presence and wildland vegetation. Both the hazard (probability of fire outbreak, distribution) and the vulnerability of urban areas can be characteriz...

Half of all Swedish forests are owned by private individuals, and at least 215,000 people work in these privately owned forest holdings. However, only lethal accidents are systematically monitored among self-employed forest workers. Therefore, data from the registries of the Swedish Work Environment Authority, the Labor Insurance Organization and the regional University Hospital in Umeå were ga...

RESUME Wide swath imagery of the ENVISAT Advanced Synthetic Aperture Radar (ASAR) may be used to study and map biophysical parameters of the Siberian forest. Within this study multi incidence-angle capacities of the ASAR Wide Swath (WS) mode for deriving forest types and biomass parameters are assessed. For this purpose a processing chain was set up to manage orthorectify, calibrate and analyse...

Timber suply modeling has evolved from examining inventory sustainability based on growth/drain relationships to sophisticated inventory and supply models. These analyses have consistently recognized regional, ownership (public/private), and species group (hardwood/softwood) differences. Recognition of product differences is fundamental to market analysis which traditionally focus on sawtimber ...
