In general, this is an area between latitudes of 25 degrees north and 25 degrees south, however, geographical limits are highly variable depending upon the area of the world and local climates. Part of her research includes carefully dosing individual mangrove trees with small amounts of nitrogen and phosphorus to understand howexcess nutrients, which are a major global threat to mangroves and other coastal ecosystems like those from industrial, residential, and agricultural sourcesaffect mangrove ecosystems.

Most pneumatophores, however, grow between 8 and 20 inches (20 and 50 cm). As the leaves age, the cells grow in size since more water is needed to dilute the accumulating salt.
