A comparison of sap flux-based evapotranspiration estimates with catchment-scale water balance

Many researchers are using sap flux to estimate tree-level transpiration, and to scale to stand- and catchment-level transpiration; yet studies evaluating the comparability of sap flux-based estimates of transpiration (E_{) with alternative methods for estimating E_t at this spatial scale are rare. Our ability to...}

Plot size recommendations for biomass estimation in a midwestern old-growth forest

The authors examine the relationship between disturbance regime and plot size for woody biomass estimation in a midwestern old-growth deciduous forest from 1926 to 1992. Analysis was done on the core 19.6 ac of a 50.1 ac forest in which every tree 4 in. d.b.h. and greater has been tagged and mapped since 1926. Five windows of time are compared?1926, 1976, 1981, 1986...

Abundance and Size Distribution of Cavity Trees in Second-Growth and Old-Growth Central Hardwood Forests

In central hardwood forests, mean cavity-tree abundance increases with increasing standsize class (seedling/sapling, pole, sawtimber, old-growth). However, within a size class, the number of cavity trees is highly variable among 0.1-ha inventory plots. Plots in young stands are most likely to have no cavity trees, but some plots may have more than 50 cavity trees/ha....

Forest fuel reduction and biomass supply: perspectives from southern private landowners

Removing excess biomass from fire-hazardous forests can serve dual purposes: enhancing the health and sustainability of forest ecosystems and supplying feedstock for energy production. The physical availability of this biomass is fairly well-known, yet availability does not necessarily translate into actual supply. We assess the perception and behavior of private...

“Have not our weary feet come to the place for which our fathers sighed?”: heirs’ property in the southern United States

Heirs? property is inherited land or real estate owned by two or more people as tenants in common. The property is typically passed to heirs without a will or with ?clouded title? outside the formal probate process. This type of land tenure presents problems to its owners because it is very difficult for heirs to leverage such assets to enhance property values?for...

Guidelines for sampling aboveground biomass and carbon in mature central hardwood forests

As impacts of climate change expand, determining accurate measures of forest biomass and associated carbon storage in forests is critical. We present sampling guidance for 12 combinations of percent error, plot size, and alpha levels by disturbance regime to help determine the optimal size of plots to estimate aboveground biomass and carbon in an old-growth Central...

Ground cover in old-growth forests of the central hardwood region

Differences in ground cover (percent cover of litter, percent cover of vegetation and litter weight) in old-growth forests across this region are not well understood. We initiated a long-term study in a three-state region to enhance knowledge in this area. We present baseline results for ground cover and compare these data across productivity regions. Thirty 0.25-ac (0...

Distribution of biomass in an Indiana old-growth forest from 1926 to 1992

We examined the structural and spatial distribution of woody biomass in relationship to disturbance in an Indiana old-growth deciduous forest over a 66-year period. Analysis was done on the core 7.92 ha of a 20.6 ha forest in which every tree 10 cm dbh and over has been tagged and mapped since 1926. Five years are compared - 1926, 1976, 1981, 1986 and 1992....
