The urban reef at Isla Verde supports various species of protected corals, sea turtles, and crustaceans, as well as many Caribbean fish. It also protects the International Airport and numerous homes and resorts on the coast.

RestoreNet locations are testing commonly used restoration techniques, including pitting, mulching, and above-ground micro sites. Here, pits have filled with water, illustrating how this technique increases soil moisture by capturing rainwater.

RestoreNet locations are testing commonly used restoration techniques, including pitting, mulching, and above-ground micro sites. Here, metal crosses create an above-ground microsite that can increase soil moisture by providing shade and collecting debris under some conditions.

RestoreNet locations are testing commonly used restoration techniques, including pitting, mulching, and above-ground micro sites. This photo shows the mulching treatment, which can increase soil moisture and lead to higher plant survival under some conditions.

USGS staff survey the Mill River near the former Hopewell Mills Dam site in Taunton, Massachusetts. Surveys at the dam-removal and culvert-retrofit sites provided topographic and bathymetric data for hydraulic models developed for the study.

A broken concrete foundation and some shattered floor tiles were all that remained of the sea turtle researchers' field station and home base after Category Four Hurricane Michael struck Cape San Blas on Oct. 10, 2018.
