Impact evidence

Describes programs. Its tax return describes what it does but we have found no measurable results in it.

Programs described in its return (3)
  1. $18,231 spent. See detail in attachment Achievements.pdf Provide Environmental Education - As a leader in the community, we will raise awareness of important environmental issues in the county and region and promote environmental ethic of Calvert County residents and visitors. We will do this both as a partner to the county nature parks and as a stand-alone organization. The Society is an advocate for public access to natural lands and waterways in the county. The Society supports the activities led by Calvert County Department of Parks & Recreation Natural Resources Division. Our nature parks, and the programs that are provided through them, are second to none. We encourage residents and visitors to the county to enjoy these parks and activities to the fullest. Our goal is to have a series of programs that inform and connect the community to its natural heritage and create a passion for the environment.
  2. $7,019 spent. See detail in attachment Achievements.pdf Preserve Natural Areas: As the pace of development increases, it is critical that natural resources are set aside for future use. 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.
  3. $6,234 spent. See detail in attachment Achievements.pdf Engage An Active Volunteer Corps: The Society provides opportunities for the community to embrace stewardship of the countys public parklands that will benefit private lands as well. It is important to foster the environmental stewardship ethic in Calvert County. Our goal is to build a pipeline of volunteers for the parks, via Calvert Stewards and youth programs.
