Natural Resources Section
Share |

ORPA's Natural Resources Section (NRS) is a special interest network for professionals who are responsible for enhancement, management, and long-term viability of natural areas and open spaces. The focus of this group is to promote an environmental stewardship ethic, with emphasis on habitat restoration, management, and protection of ecosystems and natural processes within the framework of conservation biology and open space planning and management.

The Natural Resources Section is led by Tonia Williamson, Natural Resources Coordinator of North Clackamas Park and Recreation  District.  NRS typically provides two workshops per year, one in the spring and one in the fall that are targeted to natural resource professionals. Workshop topics vary based on members' needs and focus on information related to trails, species conservation, wetlands restoration, invasives, and more.

Contact Tonia Williamson to learn more about the Natural Resources Section and to get involved with NRS.
