Summary

In the unincorporated Florida Keys (Monroe County), the Land Development Code bans planting invasive exotic species anywhere in the county, naming melaleuca, Australian pine, Brazilian pepper and seven other species outright. The same section requires 100 percent native species for all required landscaping material.

These county ordinances apply to unincorporated areas of Monroe County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Invasive exotic plant species, as defined in Section 101-1, shall not be planted within the County, including but not limited to:(1)Melaleuca, Melaleuca quinquinerva;(2)Australian Pine, Casuarina (Spp.);(3)Brazilian Pepper, Schinus terebinthifolius;(4)Sapodilla, Manilkara zapota;(5)Latherleaf, Colubrina asiatica;(6)Lead Tree, Leucaena leucocephala;(7)Seaside Mahoe, Thespesia populnea;(8)Bowstring Hemp, Sansevieria hyacinthoides;(9)Beach Naupaka, Scaevola taccada; and(10)Guinea grass, Panicum maximum.

Full Breakdown

Section 114-102(h) of the Land Development Code flatly prohibits planting invasive exotic plant species, as defined in Section 101-1, anywhere in unincorporated Monroe County. ), Brazilian pepper (Schinus terebinthifolius), sapodilla (Manilkara zapota), latherleaf (Colubrina asiatica), lead tree (Leucaena leucocephala), seaside mahoe (Thespesia populnea), bowstring hemp (Sansevieria hyacinthoides), beach naupaka (Scaevola taccada), and guinea grass (Panicum maximum), and the word 'including' makes clear the list is not exhaustive; the county biologist can flag other species under the Section 101-1 definition. The same section requires all plant material used to satisfy landscaping requirements to be Florida No.

1 grade or better under state Department of Agriculture nursery standards, free of disease, invasive pests and invasive fungi, and either drawn from the native planting list in Section 114-105 or certified native by the county biologist; Section 114-102(f) separately requires 100 percent of the plant material satisfying landscaping requirements to be native species. Hammock species face an added siting rule: they cannot be planted within 500 feet of native pineland communities under Section 114-102(i). Because tree removal in the Keys otherwise requires a development permit under Section 114-103, the code makes one exception tied directly to this ban: removing ten or fewer stems of an invasive exotic species listed in Section 114-102(h) from a residential developed lot needs no permit at all.

Violations & Fines

Planting a species named in Section 114-102(h), or installing non-native material where the code requires 100 percent native planting, is enforced by Monroe County Code Compliance as a landscaping violation; a landscape plan relying on prohibited species can be rejected outright, and installed violations are subject to Special Magistrate proceedings and required replacement at the property owner's expense.

Frequently Asked Questions

Can I plant Brazilian pepper or Australian pine on my Keys property?
No. Section 114-102(h) of the Land Development Code bans planting invasive exotic species including Brazilian pepper, Australian pine, and melaleuca anywhere in unincorporated Monroe County, and the list also covers seven other named species.
Do I need a permit to remove an invasive tree from my yard?
Not for a small amount. Section 114-103 exempts removing ten or fewer stems of a species listed in Section 114-102(h) from a residential developed lot from the development permit otherwise required for tree removal.
Does all required landscaping in the Keys have to be native?
Yes. Section 114-102(f) requires 100 percent of the plant material used to satisfy landscaping requirements to be native species drawn from the list in Section 114-105 or certified native by the county biologist.
