Limber Pine Habitat Model Using 25-Meter DEM Data

Alberta's Limber Pine habitat model was developed for the Alberta Forestry and Parks Forest Management Branch in 2015-2016. It predicts habitat suitability using variables like elevation, aspect, slope, and landscape mesotopography derived from a 25 m² resolution Digital Elevation Model. The accompanying report includes accuracy assessments against field observations.

Use Cases

• Predict habitat suitability for Limber Pine using elevation, aspect, and slope variables from the DEM.
• Assess model accuracy by comparing predicted habitat with field observation data referenced in the report.
• Analyze the influence of landscape mesotopography features like ridge and upper slope on species distribution.
• Identify areas of potential habitat where LiDAR canopy height data is unavailable, as noted in the model's methodology.

Strengths

• Model accuracy is assessed against field observation data with a detailed report.
• Spatial resolution is specified as 25 m² pixels for the DEM data.

Limitations

• Sample size and row count for the underlying model data are unknown.
• Canopy height was excluded from the model due to reliance on LiDAR data not available in all areas.
• Primary data collection occurred in 2015-2016, which may not reflect current conditions.
