Effects of logging debris treatments on five-year development of competing vegetation and planted Douglas-fir
Although considerable research has focused on the influences of logging debris treatments on soil and forest regeneration responses, few studies have identified whether debris effects are mediated by associated changes in competing vegetation abundance. At sites near Matlock, Washington, and Molalla, Oregon, studies were initiated after timber harvest to quantify the effects of three logging de...
متن کاملSoil and Douglas-fir (Pseudotsuga menziesii) foliar nitrogen responses to variable logging-debris retention and competing vegetation control in the Pacific Northwest
Experimental treatments of logging-debris retention (0%, 40%, or 80% surface coverage) and competing vegetation control (initial or annual applications) were installed at two sites in the Pacific Northwest following clearcutting Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) stands to assess short-term effects on tree N acquisition, soil N supply, and total soil N. Vegetation...
متن کاملFoundation species loss affects vegetation structure more than ecosystem function in a northeastern USA forest
Loss of foundation tree species rapidly alters ecological processes in forested ecosystems. Tsuga canadensis, an hypothesized foundation species of eastern North American forests, is declining throughout much of its range due to infestation by the nonnative insect Adelges tsugae and by removal through pre-emptive salvage logging. In replicate 0.81-ha plots, T. canadensis was cut and removed, or...
متن کاملSeasonality, Rather than Nutrient Addition or Vegetation Types, Influenced Short-Term Temperature Sensitivity of Soil Organic Carbon Decomposition
The response of microbial respiration from soil organic carbon (SOC) decomposition to environmental changes plays a key role in predicting future trends of atmospheric CO2 concentration. However, it remains uncertain whether there is a universal trend in the response of microbial respiration to increased temperature and nutrient addition among different vegetation types. In this study, soils we...
متن کاملThe effect of changing forest vegetation to rangeland on soil flora and fauna activities of the mountainous part of Kinj-Nowshahr
Soil flora and fauna play an important role in nutrient cycle and ecosystem sustainability. With the aim of investigating the changes in the activity of these soil organisms as a result of the change of vegetation from forest to rangeland in the mountainous regions of the north of the country, the present study was considered. For this purpose, in the Kinj region of Nowshahr, a forest habitat d...
