Some of their projects include a smartphone app for East African mangroves that allows anyone to collect data on mangrove health. Medicinal properties from mangroves include relieving pain, decreasing inflammation, treating diabetes, acting as an antitumor drug, ridding the body of parasites, as an antiseptic, and many, many more.

Mangroves further improve water quality by absorbing nutrients from runoff that might otherwise cause harmful algal blooms offshore. After 7 years, all three of Floridas mangrove species naturally re-established.
