1. 1. Investigation of above-ground biomass with terrestrial laser scanning : A case study of Valls Hage in Gävle

   Magister-uppsats, Högskolan i Gävle/Samhällsbyggnad

   Författare :Mathias Billenberg; [2023]
   Nyckelord :TLS; tree species; QSM; AGB; volume; wood density; biomass; allometric; point cloud;

   Sammanfattning : The thesis investigates above-ground biomass (AGB) with terrestrial laser scanning (TLS) for estimating AGB in a study area in Valls Hage, Gävle. The study used TLS for field measurements to collect highly detailed point clouds of two tree species for AGB estimation and comparison against validation data. LÄS MER

3. 2. Forest Aboveground Biomass Monitoring in Southern Sweden Using Random Forest Modelwith Sentinel-1, Sentinel-2, and LiDAR Data

   Magister-uppsats, Högskolan i Gävle/Samhällsbyggnad

   Författare :Wan Ni Lin; [2023]
   Nyckelord :Aboveground biomass; Sentinel-1; Sentinel-2; LiDAR; random forest; GEE;

   Sammanfattning : Monitoring carbon stock has emerged as a critical environmental problem among several worldwide organizations and collaborations in the context of global warming and climate change. This study seeks to provide a remote sensing solution based on three types of data, to explore the feasibility and reliability of estimating aboveground biomass (AGB) in order to improve the efficiency of monitoring carbon stock.

4. 3. Advancing understanding of tropical forest carbon dynamics through improved allometric models for palms: A case study with Prestoea montana in Puerto

   Magister-uppsats, Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildning

   Författare :Paschalis Chatzopoulos; [2021]
   Nyckelord :Above ground biomass; allometry; Luquillo Forest Dynamics Plot; Palms;

   Sammanfattning : Tropical forests are major components of Earth’s carbon stocks, but their diversity and structural complexity pose major challenges for making accurate estimates of their above ground biomass (AGB). Palms, in particular, are prominent and unique components of many tropical forests that have anatomical and physiological differences from dicot trees which affect their height - diameter allometry and consequently, our ability to accurately estimate their AGB.

5. 4. Increased Drought and Fire Intensity Regimes Reduce the Ecological Resilience of Mediterranean Forests in the South-West Australian Floristic Region

   Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

   Författare :Shareen Sanders; [2020]
   Nyckelord :Allometric models; Above-ground biomass AGB ; drought; fire; disturbance; understorey; resilience; Mediterranean.;

   Sammanfattning : Future climate projections suggest an increase in average temperature as well as a decrease in average winter rainfall across the south-west Australian floristic region (SWAFR). These adverse future climatic conditions will amplify the intensity and frequency of disturbance events such as drought and fire. LÄS MER
