Collaboratively Forecasting Landscape Change and Population Dynamics of Barren-ground Caribou
Barren-ground caribou, an ecologically and culturally important species in northern Canada, have been in decline and are threatened in the Northwest Territories (NWT). To improve capacity to explore drivers of caribou declines and test management strategies, the ALCES simulation platform was applied to develop a decision-support tool for five central barren-ground caribou (CBGC) herds (i.e., […]
Mapping Seedling Success with Remotely Piloted Aircrafts and Machine Learning
In 2024, IEG developed an innovative remote sensing workflow to identify newly planted seedlings across a reclamation area, classify them by species, and monitor their survival and growth over time. The workflow leverages high-resolution imagery collected by Remotely Piloted Aircraft (RPA) and advanced machine learning techniques. This approach scales seedling analysis from small sample plots to the entire site, delivering accurate, spatially explicit insights into seedling performance under varying site conditions. The result is faster, more informed decision-making that enhances the effectiveness and efficiency of reclamation efforts.
The method was applied to a two-hectare revegetation area planted with aspen, lodgepole pine, and white spruce. Using multispectral RPA imagery, seedlings were automatically detected, classified by species, and assessed for health using Object-Based Image Analysis and Random Forest models. Over 10,000 individual seedlings were geolocated and tagged with species and health attributes.
With precise seedling locations and spatial context, confounding factors such as slope position and microtopography were evaluated. Once these effects were accounted for, key treatment variables—like cover material and bulk density—emerged as strong drivers of seedling performance. For example, bulk density alone explained 71% of the variation in aspen growth within one soil type.
Riding Mountain National Park Vegetation Modelling
Suppression of fire and extirpation of bison have allowed forest to encroach on grassland, and maintenance of grassland is an important management priority for the park. The ALCES Flow landscape simulator was applied to explore fire and vegetation dynamics in the park in order to inform future management actions such as the use of prescribed fire.
