Differential effects of competition or microenvironment on boreal tree seedling establishment after fire We used a combination of surveys of natural vegetation and seed-sowing and seedling transplant experiments to determine the relative importance of competition and microenvironmental modification as mechanisms by which understory vegetation influences the establishment of tree seedlings in an Alaskan postfire boreal forest. Seedlings of white spruce (Picea glauca) and paper birch (Betula papyrifera) became established more frequently than expected in patches that were dominated by horsetail (Equisetum arvense), and less frequently than expected in patches of bluestem (Calamagrostis canadensis) and other vegetation. Similarly, birch and spruce, whether sown directly or transplanted as seedlings into horsetail-dominated...
