In the USVI, trees play a vital role in our ecosystems. However, many people aren’t aware of the native tree species growing all around us. In a recent Science Saturday episode, Division of Territorial Parks and Protected Areas Director Kitty Edwards was once again joined by Rudy G. O’Reilly, Jr. to explore the variety of native trees across the territory.

Mr. O’Reilly explains that native plants and trees have probably been here longer than people. As our environment changes, the plants and trees adapt.  Rudy mentions, “When we look at our landscape today, a number of plants that we see in that landscape are actually introduced species.” When land is cleared, it leads to vegetation loss, habitat destruction, and soil erosion. As mentioned in last month’s Science Saturday episode, soil erosion allows sediment to flow into our ghuts and waterways, harming native fish and other species that live there.

And it’s not just fish. Native birds have evolved to depend on native plants for food. When there are changes to their habitats, their food source is affected. Imported plants impact food sources because they alter the integrity of the local genetics. Some invasive species spread unchecked, disrupting entire ecosystems. This leads to what Rudy calls “habitat competition” between native and exotic plants.
