Abstract We measured forest-floor accumulation in ponderosa pine forests of central Oregon and asked whether selected ecological functions of the organic layer were altered by thinning and repeated burning. Experimental treatments included three thinning methods applied in 1989 (stem only, whole tree, no thin—control) in factorial combination with prescribed burning (spring 1991 and repeated in 2002; no burn—control). Forest-floor depth and mass were measured every 4–6 years from 1991 to 2015. Without fire, there was little temporal change in depth or mass for thinned (270 trees ha−1) and control (560–615 trees ha−1) treatments, indicating balanced litterfall and decay rates across these stand densities. Each burn consumed 50–70 percent of the forest floor, yet unlike thinning, postfire accumulation rates were fairly rapid, with forest-floor depth matching preburn levels within 15–20 years. Few differences in forest-floor function (litter decay, carbon storage, physical barrier restricting plant emergence, erosion protection) resulted from thinning or burning after 25 years. An exception was the loss of approximately 300 kg N ha−1 because of repeated burning, or approximately 13 percent of the total site N. This study documents long-term forest-floor development and suggests that common silvicultural practices pose few risks to organic layer functions in these forests. Study Implications: Mechanical thinning and prescribed fire are among the most widespread management practices used to restore forests in the western US to healthy, firewise conditions. We evaluated their effects on the long-term development of litter and duff layers, which serve dual roles as essential components of soil health and as fuel for potential wildfire. Our study showed that thinning and burning provided effective fuel reduction and resulted in no adverse effects to soil quality in dry ponderosa pine forests of central Oregon. Repeated burning reduced the site carbon and nitrogen pools approximately 9–13 percent, which is small compared to C located in tree biomass and N in mineral soil. Litter accumulation after burning was rapid, and we recommend burning on at least a 15–20-year cycle to limit its build-up.

Abstract The ability to estimate plant biomass is important for a wide range of ecological and land-management applications. Species-specific allometric equations for estimating plant biomass still have not been established for hardwood seedling and sapling resprouts in southeastern US Coastal Plain upland pine forests managed with frequent fire. We developed equations to estimate leaf, woody, and total biomass from stem diameter at the base for plants with diameters ranging from 0.1 to 3.3 cm for 14 species of hardwoods commonly found in this forest type. Between 21 and 53 plants per species were measured, collected, and weighed to calculate best-fit regression equations. Fitness indices for equations predicting total biomass ranged from 0.80 to 0.96 among species and was 0.83 for all species combined. Equations were generally very similar among species. Equations were most similar among species that are relatively fire tolerant and typically occupy relatively xeric sites, which had lower levels of leaf and woody biomass per stem diameter at higher diameters. These equations provide reliable estimates of understory hardwood stem biomass for common species in Coastal Plain upland pine forests managed with prescribed burning.

Abstract Analysis of covariance methods applied to long-term loblolly pine spacing trial growth data showed that the orientation of rows with regard to a particular azimuth direction had no significant impact on either basal area or dominant height growth through the age of 20 years. Results were consistent for a range of planting densities and spacings and across a range of ages that included very young ages before crown closure. These results suggest that for loblolly pine growing in the Piedmont and Coastal Plain areas of Virginia and North Carolina, the selection of row orientation at plantation establishment can be made based on criteria other than growth.

Long Term Studies

Abstract Empirical yields for a 36-year management period are presented for seven long-term studies on similar sites in loblolly-shortleaf pine (Pinus taeda L.-P. echinata Mill.) stands on the upper southern coastal plain of southern Arkansas and northern Louisiana. Total merchantable cubic-foot yields are highest for conventionally managed even-aged plantations; sawtimber cubic-foot yields are highest for intensively managed even-aged plantations and intensively managed uneven-aged stands. However, uneven-aged stands have higher board-foot sawtimber yields than the most productive even-aged stands, particularly in comparisons using the Doyle log rule. It is hypothesized that the even-aged plantations have higher cubic-foot yields because they are more fully stocked with trees of merchantable size. Conversely, the uneven-aged stands have higher board-foot yields because of the greater proportion and continuous supply of sawtimber basal area, especially in stems of large size, which can be developed using the uneven-aged selection method.
