So long, shrubs! – Part 2

Identified in both the terrestrial and aquatic Great Lakes Conservation Blueprints, this area is a prime example of globally-threatened alvar habitat, characterized by thin soils over limestone bedrock. The 12,000 hectare (30,000 ac.) property is made up of various native grasslands, forests and wetlands, supporting species such as the eastern loggerhead shrike, bobolink and Olympia marble butterfly. Vulnerable to invasive species like dog strangling vine and buckthorn, the Carden Alvar is a key target for biodiversity within the Great Lakes.

We will hike 2 km through scenic alvar to and from the work-site with equipment and all personal items. Using hand saws and loppers we will remove woody vegetation from the site and pile them in designated areas. By removing shrubs, we will help to maintain the open conditions that many alvar and grassland specialist species require.

Spend the day on the alvar surrounded by birdsong and the hum of grassland insects! By removing shrubs from alvar habitat, we will be mimicking natural processes such as fire to improve the habitat for grassland birds such as loggerhead shrike.
