CIMP187: Shrub Stem Data, 2018-2019

This data provides characteristics of shrub stems measured and sampled in 2018 and 2019 as part of a project aimed at characterizing the nature of woody plant dynamics across the treeline ecotone in central Northwest Territories, Canada. Two types of sites were targeted for sampling: "Greening" sites, where satellite remote sensing detected a significant increase in maximum productivity since year 2000, and "No Change" sites where no change had been detected. A total of 29 sites (15 'Greening' and 14 'No Change') were sampled. Four 100 metre transects were established at each site. Each transect was comprised of 11 sampling points separated by 10 metres yielding 44 sampling points per site. Measurements associated with each stem contained in the database include species, size (diameter and length), year of establishment, and vertical growth rate. Details on sample collection and processing used in the generation of the data are described in the associated publication. The data were collected as part of Project #187 (Changes in Vegetation Productivity and Phenology Across the Bathurst Caribou Range) of the Government of the Northwest Territories Department of Environment and Natural Resources Cumulative Impact Monitoring Program.
