  1. 1. Post-Fire Vegetation Recovery Monitoring using MODIS Time Series: A Case Study in California

    University essay from KTH/Geoinformatik

    Author : Julia Edje; [2023]
    Keywords : vegetation recovery; MODIS; HRT; EVI; fire; burn severity; land cover; climate zone; California;

    Abstract : Human-caused forest fires have increased in magnitude and frequency, affecting global vegetation and requiring a re-evaluation of fire regimes. Changing fire regimes have led to reduced burned areas in fire- dependent ecosystems and increased areas in fire-independent ecosystems, resulting in changes in land cover and posing a threat to native plant communities.

  3. 2. Exploring the factors affecting tree establishment after wildfire in a boreal forest in Sweden

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Robert Pim; [2023]
    Keywords : tree regeneration; tree establishment; wildfire; boreal forests; disturbance; sapling regeneration; generalized linear mixed models;

    Abstract : The factors affecting tree establishment in boreal forests after fire will help determine the community composition of the regenerating forest. These may have large consequences on the community dynamics for years after the fire disturbance. READ MORE

  4. 3. Differences and similarities in stand characteristics after prescribed burning and wildfire : implications for conservation of forest biodiversity

    University essay from SLU/Dept. of Ecology

    Author : Hannah Sophie Jakob; [2023]
    Keywords : coarse woody debris; conservation; biodiversity; boreal forest; Daldinia loculata; Fennoscandia; prescribed burning; regeneration; wildfire; woodpecker;

    Abstract : 1. Wildfires are a natural disturbance in the boreal forests of Fennoscandia and have shaped and formed forests in the past, resulting in very heterogeneous forests containing large amounts of dead and living trees in various age classes. READ MORE

  5. 4. Evaluating forest wildfire effect on tree increment patterns for boreonemoral forests in Sweden: A pilot study using remote sensing

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Joanna Eaton; [2022]
    Keywords : Physical Geography and Ecosystem analysis; Remote sensing; Sentinel-2A; Forest wildfires; dNBR; NDVI; dNDVI; Dendrochronology; Atmospheric science and biogeochemical cycles; Earth and Environmental Sciences;

    Abstract : The release of anthropogenic greenhouse gases (GHGs) has substantially increased the global mean surface air temperature. Increases in global mean surface air temperature will lead to warmer and drier conditions, promoting more frequent, long-lasting, intense forest wildfires. READ MORE

  6. 5. Post-Wildfire Debris Flows: Mapping and Analysis of Risk Factors in Western North America

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Annejet Tuinstra; [2021]
    Keywords : wildfires; debris flows; water repellent soil; North America; skogsbränder; jordskred; vattenavvisande jordlager; Nordamerika;

    Abstract : Climate change is leading to in an increase in frequency and severity of wildfires, which in turn can result in the formation of runoff-initiated post-wildfire debris flows. This type of debris flows is, like most debris flows, triggered by heavy precipitation events. READ MORE
