Welcome! Explore Natural Communities will help you see the world through the lenses of a naturalist. You’ll learn how to identify natural communities—predictable combinations of plants and animals that occur in predictable physical settings. In so doing, you’ll learn how to read the landscape—to notice patterns and draw conclusions. Looking at the world this way will open up a whole new dimension. It will enrich the time you spend outdoors—especially at the parks featured in this website!

Where to Begin?

There are four main ways to dive into this information-rich website. Pick any one that interests you:

  • Explore a particular park.

Click on Parks & Places in the menu at the top of the page. Choose Rock Creek Park to learn more about the Park and its trails, natural communities, natural history, ecological threats, and management/stewardship.

  • Explore the park's interactive Map Viewer.

Anywhere inside Parks & Places that you see the blue globe Map Viewer Icon, you can click on it to go to a park's interactive Map Viewer. Use the interactive map it to find trails, good places to see certain natural communities, points of interest, picnic areas, bathrooms, historic sites, soils, geology, and much more. Dig deeper with Details to learn more about these features. The map can show you your location in the park; tap your location on the map to learn about it. Or use the map to plan a hike through the park ahead of time: using the Measure/Analyze tool, you can "See What's Here" to learn about features along your desired path. 

To get the most out of the map viewer, explore the Map Viewer Tutorial.

  • Explore a natural community.

Click on Natural Communities in the menu at the top of the page. From there, choose a natural community—say the Chestnut Oak / Mountain Laurel Forest—to read a short description about it. Then follow a link to explore how that natural community looks in a particular park—say the Chestnut Oak / Mountain Laurel Forest in Rock Creek Park.

  • Explore the basics of ecology.

Click on Ecology Basics in the menu at the top of the page to learn about how natural communities are classified, named, and mapped. Learn more about how plants, animals, physical setting, and natural processes are all the ingredients of natural communities. Discover different factors that threaten the health of natural communities—from non-native invasive plants to fire-suppression—and what can be done to address those factors.
