HNC Stewardship Activities

An important component of Hartley’s mission is to be good stewards of Hartley Park and its natural resources. From big projects to the everyday maintenance, we strive to meet our mission with the help of volunteers, corporate service teams and community partner organizations. Through ecological restoration, biological monitoring, trail improvements, park user interactions and stewardship education, our aim is to ensure Hartley Park remains a community asset for generations to come. Take a look and see what we’ve done to make your park a better place.

You can also review our 2011 HARTLEY ENVIRONMENTAL STEWARDSHIP PLAN which was developed to guide our actions for many years to come.

Invasive Species Work

We are currently engaged in multiple efforts to preserve native species and control invasives, both native and non-native. The major force behind Hartley’s restoration efforts comes from the work of dedicated volunteers. Hartley volunteers work hard to remove existing invasive species and replace them with native species. Invasive species that receive the bulk of our efforts to date include:

  • Common and Glossy Buckthor
  • Common Tansy
  • Reed Canary Grass
  • Earthworms
  • Japanese Knotweed
  • Purple Loosestrife

Along with the invasive work in Hartley Park, Hartley Nature Center at various points in the year offers community informational/educational opportunities to learn about combating invasive species in their neighborhoods. Additionally Hartley rents plant pullers to encourage removal of buckthorn and other invasive plants.
