Park Management

Park staff monitor and protect natural communities in many ways to help deal with threats from non-native invasive plants and insects, diseases, and more.

Here are a few ways Park staff are managing some of the ecological threats to the Chestnut Oak / Mountain Laurel Forest:

You Can Help, Too!

If you are interested in helping to take care of the natural communities of Rock Creek Park, here are some ideas:


In the Park


Stay on trails and respect fences. Park staff sometimes put up fences to keep out deer or to discourage foot traffic in erosion-prone areas. You can help by staying out of fenced-in areas.


Keep your pet on a leash so that it does not disturb animals or dig up plants. Clean up after your pet to help keep streams and rivers clean.

Keep Your Eyes Open:

Alert park staff if you see any of the following along the trail: diseased vegetation, infestation by non-native insects, invasion by non-native vegetation (especially Early Detection Rapid Response species), trash, unauthorized trails, or anything that looks amiss. Make a note of your location, take a picture if you can, and contact Rock Creek Park’s Chief of Resources Management at 202-895-6010.

At Home

Landscape with Natives:

Many non-native invasive plants started out as—or still are—popular landscaping plants, so you can help limit their spread by choosing native plants for your yard. If you do plant non-natives, remove seeds and berries before wind and animals spread them. English ivy won’t produce berries unless it’s climbing a vertical surface, so keep it off trees and walls.

Protect Streams:

Keep litter, fertilizer, pet waste, and yard waste off the streets where it can wash into the storm drains that lead directly to creeks. Consider installing a rain garden in your yard to slow down stormwater run-off and help recharge the groundwater.
