Burning Potential of Fire Refuges in the Boreal Mixedwood Forest
In boreal ecosystems, wildfire severity (i.e., the extent of fire-related tree mortality) is affected by environmental conditions and fire intensity. A burned area usually includes tree patches that partially or entirely escaped fire. There are two types of post-fire residual patches: (1) patches that only escaped the last fire; and (2) patches with lower fire susceptibility, also called fire r...
متن کاملMapping stand-level forest biophysical variables for a mixedwood boreal forest using lidar: an examination of scanning density
Light detection and ranging (lidar) is becoming an increasingly popular technology among scientists for the development of predictive models of forest biophysical variables. However, before this technology can be adopted with confidence for long-term monitoring applications in Canada, robust models must be developed that can be applied and validated over large and complex forested areas. This w...
متن کاملEcosystem Responses to Partial Harvesting in Eastern Boreal Mixedwood Stands
Partial harvesting has been proposed as a key aspect to implementing ecosystem management in the Canadian boreal forest. We report on a replicated experiment located in boreal mixedwoods of Northwestern Quebec. In the winter of 2000–2001, two partial harvesting treatments, one using a dispersed pattern, and a second, which created a (400 m) gap pattern, were applied to a 90-year-old aspen-domin...
متن کاملEvaluating the Ecological Integrity of Structural Stand Density Management Models Developed for Boreal Conifers
Density management decision-support systems (e.g., modular-based structural stand density management models (SSDMMs)), which are built upon the modeling platform used to develop stand density management diagrams, incorporate a number of functional relationships derived from forest production theory and quantitative ecology. Empirically, however, the ecological integrity of these systems has not...
متن کاملForest Stand Dynamics and Ecological Factors in Relation to Dwarf
Dwarf mistletoes are markedly host specific, perennial, obligate parasites. The success of mistletoe populations is tied not only to the suitability of the environment, but also to the availability and conditions of the hosts they infect. Thus, the dynamics of forest stand development and change exert major influences on the capacity of dwarf mistletoes to spread, intensify, and cause damage to...
