Calvert Nature Society is positioned to be an advocate for public access to natural lands and waterways in the county. Our goal is to support and enhance these efforts in general throughout the county. Through our Land program, the Society will help protect natural spaces and local streams from stressors from development, climate change and invasive species. Because we will not, in most cases, be the owner or manager of these properties, we will work with partners to support land conservation and work to influence outcomes and set the stage for successful land protection initiatives. |
