  • Strategies for sampling and estimation of aboveground tree biomass

    Creator:
    Poudel, Krishna Prasad
    Abstract:
    The issue of global climate change and an increasing interest in the reduction of fossil fuel carbon dioxide emissions by using forest biomass for energy production has increased the importance of quantifying forest biomass in recent years. The official U.S. forest carbon reporting is based on the forest biomass estimates...

  • Error propagation in estimating aboveground biomass using terrestrial LiDAR

    Creator:
    Shettles, Michael A.
    Abstract:
    Broad-scale estimates of above ground forest biomass (AGB) are typically produced by applying individual-tree equations to inventory data consisting of measurements from probabilistically or purposively selected trees. The associated uncertainty for these estimates depends primarily on three sources of error that interact and propagate: (1) measurement error, the quality of...

  • Evaluating the accuracy of imputed forest biomass estimates at the project level

    Creator:
    Gagliasso, Donald
    Abstract:
    Various methods have been used to estimate the amount of above ground forest biomass across landscapes and to create biomass maps for specific stands or pixels across ownership or project areas. Without an accurate estimation method, land managers might end up with incorrect biomass estimate maps, which could lead them...

  • Quantifying Aboveground Biomass for Common Shrubs in Northeastern California

    Creator:
    Huff, Steven
    Abstract:
    Quantifying biomass is important for sustainable forest management. The purpose of this study is to obtain allometric relationships for seven species of shrubs common in northeastern California so that estimates of carbon and fuel loading may be better realized. Although some shrub biomass equations exist, such equations are limited in...

  • Examination of imputation methods to estimate status and change of forest attributes from paneled inventory data

    Creator:
    Eskelson, Bianca N. I.
    Abstract:
    The Forest Inventory and Analysis (FIA) program conducts an annual inventory throughout the United States. In the western United States, 10% of all plots (one panel) are measured annually, and a moving average is used for estimating current condition and change of forest attributes while alternative methods are sought in...

  • Predicting urban tree attributes for major species in urbanized areas of the western Pacific states

    Creator:
    Jeroue, Lacey M.
    Abstract:
    Urban forests are an essential green infrastructure of our cities. Due to the proximity of urban trees to more than 250 million people and the grey infrastructure within United States cities, urban forests are uniquely positioned to provide a host of social, environmental and economic benefits. Careful management that maximizes...
