Lethal soil temperatures during burning of masticated forest residues
Mastication of woody shrubs is used increasingly as a management option to reduce fire risk at the wildland-urban interface. Whether the resulting mulch layer leads to extreme soil heating, ifExpand

Glyphosate toxicity and the effects of long-term vegetation control on soil microbial communities
Abstract We assessed the direct and indirect effect of the herbicide glyphosate on soil microbial communities from ponderosa pine ( Pinus ponderosa ) plantations of varying site quality. Direct,Expand

Soil compaction effects on growth of young ponderosa pine following litter removal in California's Sierra Nevada
Increased use of heavy equipment and more frequent entry into forest stands has increased the potential for soil compaction and decreased productivity. We examined compaction and tree growthExpand

Assessing Soil Quality: Practicable Standards for Sustainable Forest Productivity in the United States
Productive soils form the foundation for productive forests. But unfortunately, the significance of soil seems lost to modem society. Most of us are too far removed from the natural factors ofExpand

Long-Term Soil Productivity: genesis of the concept and principles behind the program
The capacity of a forest site to capture carbon and convert it into biomass defines fundamental site productivity. In the United States, the National Forest Management Act (NFMA) of 1976 mandatesExpand

Understory vegetation response to mechanical mastication and other fuels treatments in a ponderosa pine forest
Questions: What influence does mechanical mastication and other fuel treatments have on: (1) canopy and forest floor response variables that influence understory plant development; (2) initialExpand

Microbial community responses in forest mineral soil to compaction, organic matter removal, and vegetation control
We tested three disturbance hypotheses in young conifer plantations: H1: soil compaction and removal of surface organic matter produces sustained changes in microbial community size, activity, and ...

Seedling Root Growth as a Function of Soil Density and Water Content
Compaction caused by some intensive forest management practices can reduce tree growth, but growth reduction is the result of complex interactions between soil properties and tree physiologicalExpand

Effects of organic matter removal and soil compaction on fifth-year mineral soil carbon and nitrogen contents for sites across the United States and Canada
This study describes the main treatment effects of organic matter removal and compaction and a split-plot effect of competition control on mineral soil carbon (C) and nitrogen (N) pools. TreatmentExpand
