    Definition criteria determine the success of old-growth mapping by Jamis M. Bruening, Ralph O. Dubayah, Neil Pederson, Benjamin Poulter, Leonardo Calle

    Published 2024-02-01
    “…In the first part of our analysis, we classify forests throughout the eastern US as old or not with respect to each old-growth dimension using existing old-growth definitions and data from the US Forest Inventory and Analysis (FIA) program. We estimate the proportion of forest classified as old within a hexagon grid, resulting in a unique map of old forest proportion (OFP) for each dimension. …”

    Allometric models and aboveground biomass stocks of a West African Sudan Savannah watershed in Benin by Adéyèmi Chabi, Sven Lautenbach, Vincent Oladokoun Agnila Orekan, Nicholas Kyei-Baffour

    Published 2016-08-01
    “…The accuracy of biomass density maps depends on the availability of reliable allometric models used in combination with data derived from satellites images and forest inventory data. To reduce the uncertainty in estimates of carbon emissions resulting from deforestation and forest degradation, better information on allometric equations and the spatial distribution of aboveground biomass stocks in each land use/land cover (LULC) class is needed for the different ecological zones. …”

    Assessing the Accuracy of GEDI Data for Canopy Height and Aboveground Biomass Estimates in Mediterranean Forests by Iván Dorado-Roda, Adrián Pascual, Sergio Godinho, Carlos A. Silva, Brigite Botequim, Pablo Rodríguez-Gonzálvez, Eduardo González-Ferreiro, Juan Guerra-Hernández

    Published 2021-06-01
    “…The proposed models could also be used to monitor biomass stocks at large-scale by using GEDI footprint level in Mediterranean areas, especially in remote and hard-to-reach areas for forest inventory. The findings from this study serve to provide an initial evaluation of GEDI data for estimating AGB in Mediterranean forest.…”

    Published 2020-01-01
    “…Biomass estimated from cover-based allometry was higher than estimates from the Forest Inventory and Analysis Program (FIA) at the plot-level (bias = 5 Mg ha ^−1 and RMSE = 15.5 Mg ha ^−1 ) due in part to differences in tree-level biomass allometrics. …”

    Forecasting the Cumulative Effects of Multiple Stressors on Breeding Habitat for a Steeply Declining Aerial Insectivorous Songbird, the Olive-sided Flycatcher (Contopus cooperi) by Andrea R. Norris, Leonardo Frid, Chloé Debyser, Krista L. De Groot, Jeffrey Thomas, Adam Lee, Kimberly M. Dohms, Andrew Robinson, Wendy Easton, Kathy Martin, Kathy Martin, Kristina L. Cockle

    Published 2021-05-01
    “…To predict the occurrence of olive-sided flycatcher we developed a suite of habitat suitability models using point count surveys (1997–2011) spatially- and temporally-matched with forest inventory data. Flycatcher occurrence was positively associated with small (∼10 ha) 10- to 20-year-old clearcuts, and with 10–100% tree mortality due to mountain pine beetle (Dendroctonus ponderosae) outbreaks, but we found no association with roads or distance to water. …”
