“…Gross forest growth rates are estimated as the net annual growth in growing stock volume plus the percentage of annual growing stock removed for all purposes (industrial wood and fuel wood). The gross growth for the Northeast is estimated to be 2.0% per year, with gross growth slightly higher in softwood species (Table 4- 1950 1955 1960 1965 1970 1975 1980 1985 1990 1995 Based on the growing stock volumes provided in Table 4-2 above, there are approximately 1.8 billion tons C in live above-ground biomass in the northeastern region (Table 4-5) (Smith et al, 2003). Based on the growth calculations presented in Tables 4-2 and 4-4, carbon is accumulating in the region at a rate of about 0.5% per year currently, or around 8.9 million tons C per year (Table 4-5).…”

The Nature Conservancy is participating in a Cooperative Agreement with the Department of Energy (DOE) National Energy Technology Laboratory (NETL) to explore the compatibility of carbon sequestration in terrestrial ecosystems and the conservation of biodiversity. The title of the research project is "Application and Development of Appropriate Tools and Technologies for Cost-Effective Carbon Sequestration".The objectives of the project are to: 1) improve carbon offset estimates produced in both the planning and implementation phases of projects; 2) build valid and standardized approaches to estimate project carbon benefits at a reasonable cost; and 3) lay the groundwork for implementing cost-effective projects, providing new testing ground for biodiversity protection and restoration projects that store additional atmospheric carbon. This Technical Progress Report discusses preliminary results of the six specific tasks that The Nature Conservancy is undertaking to answer research needs while facilitating the development of real projects with measurable greenhouse gas reductions. The research described in this report occurred between January 1 st and March 31 st 2006. The specific tasks discussed include:• EXECUTIVE SUMMARYThe Nature Conservancy, partners and collaborators had another productive quarter conducting research under this cooperative agreement.Inventory and remote sensing work for carbon analysis has continued in California in the North Yuba area. The University of California team used likelihood analysis and Akaike's Information Criterion to fit allometric equations of biomass vs. height and biomass vs. crown diameter for the calculation of biomass from LIDAR and QuickBird data. The team from Carnegie Institution of Washington and Stanford University has also now used an automatic crown detection algorithm on the North Yuba Quickbird data.The Nature Conservancy hosted a very successful Technical Advisory Panel meeting with 35 participants. Excellent presentations were delivered and discussion sessions convened on both project and national level approaches to measuring and monitoring carbon stocks. Expert speakers presented on the results of research sponsored by this co-operative agreement, whilst others were brought in to talk on other leading research initiative underway in the field of monitoring and measuring carbon stocks in the land-use and forestry sector.Considerable progress has been made on the Northeast feasibility study. Parts 1 and 2 of this study were submitted to John Litynski as milestone reports. Substantial analysis has already taken place for parts 3 and 4, which look at the opportunities for improving carbon storage and management on agricultural and forest lands. 6 EXPERIMENTAL Task 1 Carbon Inventory AdvancementsCarbon Inventories can be increased and costs lowered through improved techniques. Forest Inventories have been carried out for a number of reasons; to use for M3DADI calibration (task 2), for use in carbon baseline development (task 3) and for development of new...

“…It has been estimated that there are over 12.7 million ha of ponderosa pine forests in the western U.S. (Smith et al 2004). The benefits of uneven-aged management of ponderosa pine have been demonstrated for decades and provide a context for exploring the effects of alternative forest management practices on stand growth (for examples see Covington and Moore 1994;Covington et al 2001;Arno and Fiedler 2005;Fule et al 1997).…”

“…If the forest management strategy of adopting possibly more resilient uneven-aged stand structures across landscapes is to be more widely adopted by the forestry profession, tools for projecting stand growth are necessary. Because most forestland in the U.S. is owned by private citizens (Smith et al 2004), the efficacy of alternative forest management paradigms may need to be evaluated both ecologically (e.g., invasive pest resistance) and economically (e.g., wood production and carbon credits).…”

“…Forest ecosystems across the U.S. have been providing a myriad of resources (e.g., clean air, water, recreation, wildlife habitat, wood, fuel, aesthetics) to the populace for centuries (Smith et al 2004). Substantial portions of U.S. forestland have been directly managed for resource extraction or indirectly altered through fire suppression and fragmentation.…”

Effects of tree size and spatial distribution on growth of ponderosa pine forests under alternative management scenarios

2008

Forest ecosystems may be actively managed toward heterogeneous stand structures to provide both economic (e.g., wood production and carbon credits) and environmental benefits (e.g., invasive pest resistance). In order to facilitate wider adoption of possibly more sustainable forest stand structures, defining growth expectations among alternative management scenarios is crucial. To estimate the effect of tree size and spatial distributions on growth for forest structures commonly considered in uneven-aged forest stand management, large (0.2 ha?) plots were established in 14 uneven-aged ponderosa pine stands in eastern Montana. All study trees were stem-mapped and measured for diameter and 10-year sapwood and basal area increment. A generalized growth model was developed to predict both total and merchantable 10-year basal area increment for nine hypothetical stand structures [three diameter distributions (reverse-J, irregular, flat) 9 three spatial distributions (clumpy, partial clumpy, uniform)]. Results indicate that the size and spatial distributions of individual trees have a considerable effect on overall stand growth. The greatest total stand growth was in stands with reverse ''J'' shaped tree size distributions, while the greatest merchantable stand growth was in stands with ''flat'' diameter distributions and uniform spatial distributions. Through better comprehension of generalized uneven-aged stand growth dynamics, forest managers may better assess the effects of alternative stand structures on stand growth while providing forest stand structures that may be more resilient in a changing climate.

“…As of 2002, nonindustrial private owners held over 151 M ha, or 49% of forestland in the nation (Smith et al 2004), with about 10.3 M family forest owners holding 40% of the forested area (Butler and Leatherberry 2004). Industrial owners held an additional 9%, and public forestland accounted for the remainder (Smith 2004).…”
