Monitoring Cumulative Effects of Human Activity on Alberta’s (Canada) Biodiversity

Abstract

Due to its significant natural resource wealth, the province of Alberta in western Canada has experienced rapid expansion of related industrial activities (forestry, agriculture, and oil and gas exploration and development), as well as associated population growth, over recent decades. The resulting rate of conversion of natural ecosystems to support these activities led to increasing concerns regarding their cumulative effects on Alberta's biodiversity. As a result, in 2007, the Alberta Biodiversity Monitoring Institute (ABMI) was formally established to monitor the status and trends of Alberta's species, their habitats, as well as human footprint (HF).

The ABMI is a not-for-profit scientific organization that operates at arm's length from government and industry. The goal of the ABMI is to provide relevant scientific information on the state of Alberta's biodiversity to support natural resource and land-use decision making in the province. To meet this goal, the ABMI employs a systematic grid of 1,656 site locations across the province, spaced 20 km apart, to collect biodiversity information on terrestrial and wetland sites. At each location, data and field samples are collected for a wide range of plant and animal species through on-the-ground measurements, and also using motion-sensitive camera traps and acoustic technology. Since 2007, over 480,000 specimens-data on over 3000 species have been collected and processed, many of which represent new scientific records for the province, sometimes new records for Canada, and even records new to science. Annually, a percentage of the total sites is surveyed, with the sites revisited approximately every 7 years to measure trend in species abundance.

In addition to field surveys, Alberta's land cover and human footprint is monitored using remote sensing technology at two spatial scales. To report on patterns and trend in human footprint, the ABMI classifies human footprint into 115 feature types, which are then rolled up into the categories of energy, forestry, agriculture, residential and industrial, human-created water bodies, and transportation. The ABMI's accumulated biodiversity and HF database supports the creation of predictive species models that provide information on spatial distribution, habitat associations, responses to HF, and predicted relative abundance for over 800 species, including mammals, birds, soil mites, vascular plants, mosses (bryophytes), and lichens.

The scale and depth of the ABMI's monitoring program and biodiversity data make it a unique program nationally, and a leader internationally. In addition to ongoing protocol development and data analysis, the ABMI is committed to deriving value from its data and information for a wide range of Alberta stakeholders through concerted knowledge translation and stakeholder engagement efforts.
