Environment Cardinal Creek Wildlife Conservation The City of Ottawa and the Rideau Valley Conservation Authority have launched a Stream Watch program to assess the health of the Cardinal Creek. We are seeking volunteers and accepting pictures! Tree Planting Plan Tree Planting Plan - Fall 2007 (PDF) Following up a meeting with the Forestry Services of the City of Ottawa, we received a draft tree planting plan.

Each spring we go around our parks, streets, but most importantly around the Cardinal Creek ravine area and pick up litter. Don't miss the next Spring Clean up event!
