Chaparral growth-ring analysis as an indicator of stand biomass development

Chaparral wildfires typically create even-aged stands of vegetation that grow quickly in the first 2 decades following a fire. Patterns of this growth are important for understanding ecosystem productivity and re-establishment success, but are logistically challenging to measure over long time periods. We tested the utility of a novel method of using shrub growth rings...

Response of advance lodgepole pine regeneration to overstory removal in eastern Idaho

Twenty-two stands of advance lodgepole pine released with overstory removal were sampled to determine height growth response. Tree and site characteristics correlated with release response were identified, and a mathematical model was developed to predict height growth in years 6 through 10 after release as a function of residual overstory basal area, height at release...

Response of Douglas-fir advance regeneration to overstory removal

A statistical model is presented that predicts periodic height growth for released Pseudotsuga menziesii var. glauca [Beissn.] Franco advance regeneration in central Idaho. Individual tree and site variables were used to construct a model that predicts 5-year height growth for years 6 through 10 after release. Habitat type and height growth prior to...

Combining ground-based measurements and MODIS-based spectral vegetation indices to track biomass accumulation in post-fire chaparral

Multi-temporal satellite imagery can provide valuable information on the patterns of vegetation growth over large spatial extents and long time periods, but corresponding ground-referenced biomass information is often difficult to acquire, especially at an annual scale. In this study, we test the relationship between annual biomass estimated using shrub growth rings...

Developing resilient ponderosa pine forests with mechanical thinning and prescribed fire in central Oregon's pumice region

Thinning and prescribed burning are common management practices for reducing fuel buildup in ponderosa pine forests. However, it is not well understood if their combined use is required to lower wildfire risk and to help restore natural ecological function. We compared 16 treatment combinations of thinning, prescribed fire, and slash retention for two decades...

TRIM timber projections: an evaluation based on forest inventory measurements.

Two consecutive timberland inventories collected from permanent plots in the natural pine type in North Carolina were used to evaluate the timber resource inventory model (TRIM). This study compares model predictions with field measurements and examines the effect of inventory data aggregation on the accuracy of projections. Projections were repeated for two geographic...

Projecting other public inventories for the 2005 RPA timber assessment update.

This study gives an overview of the current inventory status and the projection of future forest inventories on other public timberland. Other public lands are lands administered by state, local, and federal government but excluding National Forest System lands. These projections were used as part of the 2005 USDA Forest Service Resource Planning Act timber assessment...

A landscape-scale wildland fire study using coupled weather-wildland fire model and airborne remote sensing

We examine the Esperanza fire, a Santa Ana-driven wildland fire that occurred in complex terrain in spatially heterogeneous chaparral fuels, using airborne remote sensing imagery from the FireMapper thermal-imaging radiometer and a coupled weather-wildland fire model. The radiometer data maps fire intensity and is used to evaluate the error in the extent of the...

Case study : performance of a house built on a treated wood foundation system in a cold climate

Performance attributes of a home, constructed in 2001 in Madison, WI, on a treated-wood foundation system were investigated over a multiyear period. Temperature conditions in the basement of the building were, without exception, comfortable, even though the basement was not provided with supply registers for heating or cooling. Basement humidity conditions were...

Conifer root proliferation after 20 years of soil compaction

Soil compaction is known to limit plant growth by reducing soil macroporosity and restricting gas, water, and root movement. Recent evidence from study sites across the United States and Canada, however, suggests that tree growth is not universally affected by soil compaction from forest harvesting practices. Our observational study examined rooting patterns in mixed...

Private timberlands: growing demands, shrinking land base.

By 2050, US timberland area is projected to be about 3 percent smaller than today due to increasing demands for urban and related land uses from another 126 million people. An increasing area of southern planted pine will be accompanied by a reduction in the area of upland hardwoods. Hardwoods will continue to dominate the forested landscape in the South. Plantation...

Assessing fire emissions from tropical savanna and forests of central Brazil

Wildfires in tropical forest and savanna are a strong source of trace gas and particulate emissions to the atmosphere, but estimates of the continental-scale impacts are limited by large uncertainties in the rates of fire occurrence and biomass combustion. Satellite-based remote sensing offers promise for characterizing fire physical properties and impacts on the...

Interaction of fire and community development in chaparral of southern California

Fire is an ecosystem property rather than an exogenous force in southern California chaparral, and it interacts with processes of drought-mediated canopy development, production, and mortality to affect stability of community composition.

The physiological basis for regeneration response to variable retention harvest treatments in three pine species

The role of silviculture in ecosystem management: a practice in transition

The cedar (Thuja plicata) -hemlock (Tsuga heterophylla) -white pine (Pinus monticola) forests are some of the most productive in North America. Silvicultural practices used in these forests originated in Europe and usually concentrated on producing high-value commercial products.

EcoSmart Fire as structure ignition model in wildland urban interface: predictions and validations

EcoSmartFire is a Windows program that models heat damage and piloted ignition of structures from radiant exposure to discrete landscaped tree fires. It calculates the radiant heat transfer from cylindrical shaped fires to the walls and roof of the structure while accounting for radiation shadowing, attenuation, and ground reflections. Tests of litter burn, a 0.6 m...
