Aerial Riparian Assessments


Lesser Slave Lake (2005)

The Alberta Conservation Association used aerial videography to broadly quantify the health of LSL’s shoreline habitat with respect associated landuse. The information was intended to enable regulatory and community groups to make informed decisions regarding the development of LSL’s shoreline. 

The majority of the Riparian Management Area (hereafter riparian zone) at Lesser Slave Lake was classified as healthy (78.7% of the total length of the shoreline) with lesser proportions identified as moderately impaired (12.5%) or highly impaired (8.8%).

Swan River Including the Moosehorn and Inverness Rivers (2010)

The main objectives of this project were to visually document and assess (qualitative and quantitative) the Swan River and 2 tributaries’ riparian habitat. Low-level aerial videography, and the accompanying Riparian Health Score Sheets (assessed from collected aerial video) and GIS mapping were used to collect and display this information. This information can be used to monitor the results of habitat conservation efforts, facilitate aquatic habitat protection and promote low impact development of the shoreline.

South Heart River & West Prairie River (2009) 

Low-level aerial videography was used to assess the health and integrity of riparian areas along selected reaches of the South Heart and West Prairie Rivers. The South Heart River, a major tributary to Lesser Slave Lake is a key walleye spawning river for this watershed (Osokin and Tchir 2006). It’s association with the Horse Lakes complex and Buffalo Bay also contributes to its importance to many wildlife species including migratory waterfowl. Concerns have been raised over the continued habitat viability of this river for walleye due to  agriculture operations, including cattle grazing and haying of the riparian areas.
