Live tree biomass estimates are essential for carbon accounting, bioenergy feasibility studies, and other analyses. Several models are currently used for estimating tree biomass. Each of these incorporates different calculation methods that may significantly impact the estimates of total aboveground tree biomass, merchantable biomass, and carbon pools. Consequently, carbon markets, bioenergy projects, and similar efforts may be affected. In addition to differences in allometric equations, the various methods are most suitable for particular geographic scales of analysis. We examine three approaches that might be used for midscale analyses (e.g., 25,000 to several million acres) and compare the regional models with equations developed by Jenkins et al. and with the component ratio method (CRM). These three methods produce relatively similar estimates of total aboveground biomass for softwood species in Oregon, but substantially different estimates for the proportion of total biomass that is merchantable . For the major softwood species in Oregon, the total aboveground biomass using the CRM is 3 percent lower than estimates with regional equations, and the Jenkins models produce estimates that are 17 percent higher. However, on average, the proportion of softwood merchantable biomass computed with CRM is about 83 percent of the total aboveground biomass with little variation from species to species, whereas regional models estimate that 72 percent is merchantable, and the Jenkins equations estimate that 78 percent is merchantable.

Timber availability, aboveground tree biomass, and changes in aboveground carbon pools are important consequences of landscape management. There are several models available for calculating tree volume and aboveground tree biomass pools. This paper documents species-specific regional equations for tree volume and aboveground live tree biomass estimation that might be used to examine consequences of midscale landscape management in the Pacific Northwest. These regional equations were applied to a landscape in the upper Deschutes study area in central Oregon. We demonstrate an analysis of the changes in aboveground tree biomass and wood product availability at the scale of several watersheds on general forest lands under an active fuel-treatment management scenario. Our approach lays a foundation for further landscape management analysis, such as financial analysis of timber product and biomass supply, forest carbon sequestration, wildlife habitat suitability, and fuel reduction related studies.

Advances in close-range and remote sensing technologies are driving innovations in forest resource assessments and monitoring on varying scales. Data acquired with airborne and spaceborne platforms provide high(er) spatial resolution, more frequent coverage, and more spectral information. Recent developments in ground-based sensors have advanced 3D measurements, low-cost permanent systems, and community-based monitoring of forests. The UNFCCC REDD+ mechanism has advanced the remote sensing community and the development of forest geospatial products that can be used by countries for the international reporting and national forest monitoring. However, an urgent need remains to better understand the options and limitations of remote and close-range sensing techniques in the field of forest degradation and forest change. Therefore, we invite scientists working on remote sensing technologies, close-range sensing, and field data to contribute to this Special Issue. Topics of interest include: (1) novel remote sensing applications that can meet the needs of forest resource information and REDD+ MRV, (2) case studies of applying remote sensing data for REDD+ MRV, (3) timeseries algorithms and methodologies for forest resource assessment on different spatial scales varying from the tree to the national level, and (4) novel close-range sensing applications that can support sustainable forestry and REDD+ MRV. We particularly welcome submissions on data fusion.

Photo imagery is a promising non-destructive method for estimating the above-ground biomass of tree seedlings. This report describes a test of this new method using 9-year-old naturally regenerated white spruce seedlings growing in the understory of a mixed conifer shelterwood. The seedlings were exposed to one of three mechanical release treatments to examine the effects of seasonal timing of release on physiology and growth of white spruce. Two photographs of each seedling were taken in the field and used to measure the vertical projected area of the seedling crowns. The seedlings were then harvested, separated, and dried to estimate total above-ground and component biomass. Regression analysis was used to determine the relationship between seedling biomass and projected area. The results indicate the usefulness of photo imagery as an alternative to traditional methods of biomass estimation.
