    A regional assessment of land‐based carbon mitigation potentials: Bioenergy, BECCS, reforestation, and forest management by Andreas Krause, Thomas Knoke, Anja Rammig

    Published 2020-05-01
    “…The model represents the current state in Bavaria adequately, with a simulated forest biomass 12.9 ± 0.4% lower than data from national forest inventories. Future land‐use changes according to two ambitious land‐use harmonization scenarios (SSP1xRCP2.6, SSP4xRCP3.4) achieve a mitigation of 206 and 247 Mt C (2015–2100 period) via reforestation and the cultivation and burning of dedicated bioenergy crops, partly combined with carbon capture and storage. …”

    Improved LSTM Model for Boreal Forest Height Mapping Using Sentinel-1 Time Series by Shaojia Ge, Weimin Su, Hong Gu, Yrjö Rauste, Jaan Praks, Oleg Antropov

    Published 2022-11-01
    “…Time series of SAR imagery combined with reference ground data can be suitable for producing forest inventories. Copernicus Sentinel-1 imagery is particularly interesting for forest mapping because of its free availability to data users; however, temporal dependencies within SAR time series that can potentially improve mapping accuracy are rarely explored. …”

    Demographic changes in China's forests from 1998 to 2018 by Yanli Dong, Evgenios Agathokleous, Shirong Liu, Zhen Yu

    Published 2023-01-01
    “…Methods: We applied Forest Stability Index (FSI) and the relative change of FSI (%FSI) to describe the population dynamics of tree species and structure in China since 1998, using field-survey data collected from over 200,000 plot-records from the 6th to 9th National Forest Inventories (NFIs). Results: The overall populations of both natural and planted forests have grown rapidly from 1998 to 2018, while the range of changes in the relative tree density was more variable for natural forests (ranging from −8.53% to 42.46%) than for planted forests (ranging from −1.01% to 13.31%). …”
