Grassland and Grouse Project


The ASCCA is being invaded! By introduced plants to be correct.  Not all of the plants you’ll see at the ASCCA are native to Alberta’s forests and grasslands. Many are invasive species that choke out native plants, and reduce habitat for birds such as the Sharp-Tailed Grouse.  The Grassland and Grouse Project aimed to identify invasive plants, animals at risk, and control strategies. 

This project was in memory of Sandy Cross, who passed away at 89 years of age on December 13, 2003.  He loved both the native grassland and the Sharp-Tailed Grouse.

The Grassland and Grouse Project

The full Project Proposal (staff, 2005) includes the Grassland and Grouse Project goals, background, and action plans, down to the last detail.

As an introduction to the project, the Protection of Native Grassland and Grouse Report (Dankers, 2005) outlines invasive plant species and control methods.  The habitat needs of grouse are introduced, as well as methods for monitoring vegetation.

In the Weed Management Report  (Hermann, 2005) you can find photos and descriptions of the invasive weeds targeted in the Grassland and Grouse Project.  Weed control measures are also discussed.

Our 2006 Bird Survey helped identify which species make their homes in the native grasslands.  It also revealed who might be affected by weed control measures such as mowing.

The Grassland and Grouse Report: Phase 3 (Herberts, 2007) includes statistics on native grassland, monitoring and control of introduced species, pasture mapping, and bird counts.
