Erosion is caused by water and wind, not trail users. Responsible riding minimizes impact. Patrollers must learn the environmental concerns and be prepared to respond to objections. All trail users loosen soil and speed erosion.
Limited funding compounds the problems of the park.
Deer consume the undergrowth and destroy young plants. Exotic species have gained a foothold and uncontroled vine growth destroy native plants. Some species use the park for breeding and many are not found anywhere else in the city. Although formerly a polluted industrial corridor, years of preservation effort has restored this resource. Patrollers need to explain, tactfully, to other mountain bikers why they should follow these rules and the consequences of breaking them.
