Australian pine (Casuarina equisetifolia) is an invasive species in Florida:
-
-
Threatens native plant and animal species
Australian pines can displace native plants and wildlife habitats, which are critical for threatened and endangered species.
-
Causes beach erosion
Australian pines have shallow root systems that contribute to beach erosion.
-
Hazards during high winds
Australian pines are prone to toppling during high winds, which can be a hazard to coastal storm evacuation routes.
-
-
Interferes with nesting
The dense root system of Australian pines can interfere with the nesting activities of endangered American crocodiles and sea turtles.
-
Produces toxic leaves
The leaves of Australian pines contain a chemical that kills native plants growing below.
Australian pines were originally planted in Florida in the 1890s for shade, lumber, and as a windbreak. However, they have since spread beyond their intended area and are now considered a category I invasive species in Florida.
