John's Island Environmental Restoration Project

 
John's Island

Project Location
In the central area of the lagoon at the mouth of the West Palm Beach (C-51) Canal.

The Problem
Historically, John’s Island was a small intertidal and submerged shallow water habitat. Over time the island grew to approximately 6.4 acres from the placement of fill dredged out of the Intracoastal Waterway and was taken over by exotic non-native vegetation.

The Solution
Remove exotic plants, return the island to it’s original elevation, and restore native habitats.

Project Overview

  • Removed approximately 6 acres of exotic vegetation including seaside mahoe, Australian pine, and Brazilian pepper.
  • Excavated and transported 17,000 cubic yards of dredge spoil to Snook Islands to create mangrove islands and seagrass habitat.
  • Restored 1.7 acres of existing mangroves through the creation of a series of tidal channels to provide flushing to the mangrove community.
  • Created 1.4 acres of tropical maritime hammock.
  • Planted 3 acres of red mangroves and planted cordgrass along 1,190 feet of tidal channels.
  • Mangrove seedlings used in this project were collected and planted by many volunteer groups including Forest Hill High School and Jupiter High School Environmental Academies and the West Palm Beach Fishing Club.
  • Completed in June 2004.

Benefits

  • Recreates a variety of intertidal habitats for fish, manatee, birds, and invertebrates.
  • Creates increasingly scarce maritime hammock habitat.
  • Provides excavated spoil to create seagrass recruitment at Snook Islands Natural Area.
