GLARO GIS: Conservation And Recreation Lands (CARL)

The CARL GIS layer created by specialists in DU's Great Lakes/Atlantic Regional Office

What is CARL?

CARL (Conservation And Recreation Lands) is a GIS (Geographic Information Systems) layer that contains information on conservation and recreation lands in the Great Lakes. It can be used in conjunction with other GIS layers for developing landscape and long-term planning perspectives for conservation activities. CARL was developed by incorporating existing GIS layers with hard-copy maps and online information.

Why is CARL important?

Knowing where existing conservation and recreation lands are located and what level of protection exists can have a profound impact the ability of organizations that own land to plan and implement conservation activities. A consistent and complete map of these areas will be a powerful tool for developing strategic plans, coordination and education for conservation at the local, regional and state levels.
