The Hidden Threat in Miami’s Urban Forest
South Florida is home to some of the most aggressive invasive tree species in the United States. These non-native trees displace native vegetation, damage infrastructure, alter ecosystems, and can dramatically reduce property values. As a Miami homeowner, knowing which trees are invasive – and what to do about them – protects both your property and the broader environment.
Australian Pine (Casuarina equisetifolia)
Despite its name, Australian pine isn’t actually a pine tree – it’s a fast-growing coastal invader that has colonized shorelines, vacant lots, and disturbed areas throughout Miami-Dade. Australian pines are extremely wind-vulnerable due to their shallow root systems and brittle wood, making them one of the most dangerous trees in hurricane conditions. They were responsible for a disproportionate share of property damage during Hurricanes Andrew and Irma. It’s illegal to plant Australian pine in Florida, and removal is strongly encouraged. No permit is needed to remove them in most jurisdictions.
Brazilian Pepper (Schinus terebinthifolia)
Often called the “Florida holly” for its bright red berries in winter, Brazilian pepper is classified as a Category I invasive by the Florida Invasive Species Council – the most harmful designation. It forms dense thickets that crowd out native plants, produces chemicals that inhibit the growth of neighboring plants (allelopathy), and its sap can cause skin irritation similar to poison ivy. Brazilian pepper spreads aggressively via birds that eat its berries. Removal is encouraged and typically doesn’t require a permit since it’s classified as an invasive exotic.
Melaleuca (Melaleuca quinquenervia)
Originally planted in the early 1900s in a misguided attempt to dry up the Everglades, melaleuca has become one of Florida’s most notorious invasive trees. A single tree can produce millions of seeds, and it can grow 3–6 feet per year. While massive eradication efforts have reduced its spread in natural areas, melaleuca still appears in residential and commercial landscapes throughout Miami-Dade. The good news: when removed, melaleuca wood makes excellent mulch.
Carrotwood (Cupaniopsis anacardioides)
This attractive shade tree from Australia was widely planted in South Florida landscapes before its invasive potential was recognized. Carrotwood produces large quantities of seeds that are spread by birds and have invaded natural areas, particularly coastal hammocks and mangrove margins. It’s now listed as a prohibited species in Florida. If you have carrotwood on your property, removal and replacement with a native alternative is recommended.
Java Plum (Syzygium cumini)
A large evergreen tree that produces messy purple fruit and has escaped cultivation to invade natural areas across South Florida. Java plum forms dense canopy cover that shades out native understory plants. Its aggressive root system can also damage sidewalks and foundations.
Bishopwood (Bischofia javanica)
This fast-growing Asian species was introduced as an ornamental but has become a serious invader in South Florida hammocks and disturbed areas. It produces copious quantities of small fruits that stain surfaces and attract pests, and its aggressive growth habit allows it to outcompete native species for light and resources.
What to Do If You Have Invasive Trees
The good news about removing invasive trees is that most municipalities not only don’t require permits for their removal – they actively encourage it. Some areas even offer assistance programs or reduced disposal fees for invasive species removal. When removing invasives, stump treatment with an approved herbicide is often necessary to prevent regrowth, particularly for Brazilian pepper and melaleuca.
After removal, consider replanting with native species like gumbo limbo, pigeon plum, paradise tree, or green buttonwood. These provide equivalent or better shade, are hurricane-resistant, and support local wildlife.
