Worldwide, invasive non-native plant and wildlife species critically degrade natural processes within
ecosystems and are a direct result of human influence. Often they do not have the natural checks and
balances (diseases, pests, climate factors, predators, etc.) found in their native habitats.
Invasive non-native plant species in RBNERR are a significant management issue. Dominant invasive species
include Australian pine, Brazilian pepper, melaleuca, latherleaf, climbing fern and a number of other
non-native plants that are disrupting the native biodiversity of RBNERR natural communities. Natural
communities that are at highest risk include those located on barrier islands and within transition zones
such as freshwater marshes.
Invasive animals found in RBNERR include feral hogs, found on barrier islands and uplands within RBNERR.
Feral hogs have recently been observed by staff depredating sea turtle nests on Keewaydin Island, located
within RBNERR boundaries. Other non-native animals observed in RBNERR include spiny iguanas, Burmese pythons
and marine invasives such as the Asian green mussel or African cichlids.
