Managing the Dry Douglas-fir Forests
Uneven-aged interior Douglas-fir stand structure and dynamics are complexas a result of irregular fire history, insect and disease outbreaks, and variousforms of partial harvesting and range use. Stocking, crown closure, canopylayering, size-age relationships, and spatial distribution are highly variablefrom one stand to another and within any one stand. Many different factors<l...
متن کاملEffects of Cattle Grazing on Birds in Interior Douglas-fir (Pseudotsuga menziesii) Forests of British Columbia
Livestock grazing is a dominant land use across North America and although the effects of grazing on birds have been studied in grassland, shrubland, and riparian habitats, studies of the effects in forests are rare. We investigated the effects of cattle grazing in forests on vegetation, the relationships between vegetation characteristics and the abundance of foraging and nesting guilds of bir...
متن کاملLidar Remote Sensing of the Canopy Structure and Biophysical Properties of Douglas-Fir Western Hemlock Forests
Scanning lidar remote sensing systems have recently and leaf area index (LAI) over a wide range, up to 1200 become available for use in ecological applications. UnMg ha21 of biomass and an LAI of 12, with 90% and like conventional microwave and optical sensors, lidar 75% of variance explained, respectively. Furthermore, we sensors directly measure the distribution of vegetation were able to mak...

متن کاملForest Stand Structure and Pattern of Old-Growth Western Hemlock/Douglas- Fir and Mixed-Conifer Forests
With fire suppression, many western forests are expected to have fewer gaps and higher stem density of shade-tolerant species as light competition becomes a more significant influence on stand pattern and composition. We compared species composition, structure, spatial pattern, and environmental factors such as light and soil moisture between two old-growth forests: Pacific Northwest western he...
