Estimate of plant canopy cover at wetlands in the oil sands region by Alberta Environment and Parks for the OSM program. Used as an estimate of plant community productivity. Used to validate lidar measurements.

Usage Considerations or Constraints Five LAI measurements were taken along three transects at each wetland site extending from upland toward open water (shallow open water wetland), or toward the centre of the wetland (bog, fen). Therefore, canopy cover was not present at many locations. Readings were taken at all plots to establish baseline. If numeric readings are present there was sufficient canopy cover for LAI data collection, any other reading (i.e., 'nodata') indicates no canopy cover or associated measurement. Data are single time-point in situ measurements collected mid-growing season; Data are collected with a hand-held plant canopy analyser (Licor LAI-2200C; non-destructive sampling) that may affect accuracy; Data are collected mid-July to end-July to estimate max. canopy extent, but will vary across the growing season particularly for deciduous vegetation.
