It provides a snapshot of the current condition of the environment and the pressures that impact it. This document examines the state of the environment in Lacombe County through a scientific and socio-economic planning structure. The scientific approach focuses on analysing available data to identify and assess changes in the environment over time. The planning approach uses social norms to compare and rank alternative choices, to balance environmental, economic and social objectives, and to initiate management options. The report outlines community perception, scientific data, current environmental legislation and environmental extension programs. It is a compilation of information gathered from various sources and provides us with a baseline. It does not include management recommendations or future planning considerations. This document is a snapshot in time; it represents only the data that is available at the time of writing. Lacombe County is located in Central Alberta, straddling six towns and villages and bordering five counties. The County is mostly rural, with a strong industry component along the Queen Elizabeth II Highway and Highway 597. The County has approximately 10,000 residents and covers 712,960 acres or 2,885 km2. It is situated in both the Boreal Forest and Parkland Natural Regions of Alberta. It boasts a wide diversity of ecosystems, including numerous water bodies, and is home to the popular summer destinations of Gull, Buffalo and Sylvan Lakes. J.J. Collette Natural Area, which boasts a number of rare and special plants and animals, is also found within the County boundaries. Due to the geographic location and abundance of fertile farmland, the County faces some unique challenges. A very high percentage, 84%, of land is used for either agriculture or development, leaving only 16% of the lands in a natural ecological state. There is also a very large component of linear disturbance in the County, with up to 9.3% of the land within the County used by pipelines, transmission lines, roads etc. Nine environmental indicators were chosen to measure and report on the state of the environment. These indicators are based on various sources such as the Alberta Environment and Sustainable Resource Development Water Quality Guidelines, Alberta Agriculture, and previously published State of the Watershed reports in the province. The indicators are grouped in four categories: land use, water quality, bio-indicators and human impacts. Where relevant, a three point scale of good, fair and poor was used to rank the indicators. Of the nine indicators, one indicator was measured ‘good’, two indicators were measured ‘fair’ and three were measured as ‘poor’. The remaining three indicators were not ranked, due either to insufficient data or the lack of a scale that was appropriate for the County. The following table summarizes the rankings. For indicators that lack a scale, the measurement in future reports will be based on the percentage of change that occurs between the years of reporting.

This information, along with views collected from the community in an extensive consultation process conducted in 2012, will help to determine priorities and make decisions. Lacombe County is developing an Environmental Management Plan, which is scheduled to be completed and released in 2014. This document will be distributed for public comment before it is adopted by Council. This is the first State of the Environment report to be written for Lacombe County. We will update this document on a regular schedule to accurately reflect changes in the environment in Lacombe County.
