New Report Outlines Restoration Activities to Speed Seagrass Recovery in Florida Keys National Marine Sanctuary

17.12.2010
Results of a five-year monitoring effort to repair seagrass damaged in a boat grounding incident suggest that restoration techniques such as replanting seagrass can speed recovery time. The finding is included in a new report released today by NOAA’s Office of National Marine Sanctuaries.

The National Marine Sanctuaries Conservation Series report, “N-Control Seagrass Restoration Monitoring Report Monitoring Events 2003-2008,” presents results of efforts to repair a nearly 1,000-square-foot (92.8-square-meter) swath of seagrass that was damaged on May 29, 2001, when a 45-foot power boat, the N-Control, grounded in Florida Keys National Marine Sanctuary.

Seagrass beds are an important habitat in the sanctuary. They provide nurseries and homes for numerous species of fish and invertebrates and serve as storm surge buffers for the low-lying Florida Keys. However, shallow seagrass beds in the Florida Keys are being damaged by vessel groundings. In 2007, an estimated 217 reported boat groundings occurred in the sanctuary, with approximately 80 percent occurring on seagrass beds. Vessel groundings damage seagrass, leaving barren areas where marine life once flourished.

Restoration techniques at the N-Control grounding site included replanting seagrass and installing stakes for birds to roost on. The use of stakes to attract birds provides a natural way to fertilize seagrass beds as bird feces are high in nutrients needed by the growing seagrass. Among the key findings in the report:

After five years, the damaged area is gaining seagrass and coral coverage, though it hasn’t reached pre-grounding baseline levels.

Rather than leaving the site to recover on its own, restoration activities have significantly reduced the amount of time required for damaged seagrass beds in the monitoring area to recover.

“This report highlights the critical science needed to understand and restore our sensitive marine habitats,” said Sean Morton, superintendent, Florida Keys National Marine Sanctuary. “It’s also an important reminder that boaters need to know where they are going before heading out on the water to prevent groundings in the first place. Make sure you have up-to-date NOAA nautical charts, and always pay attention to the signs, channel markers and informational buoys.”

Currently, more than 30 seagrass restoration projects are underway at the sanctuary.

Florida Keys National Marine Sanctuary protects 2,900 square nautical miles of critical marine habitat, including coral reef, hard bottom, seagrass meadow, mangrove communities and sand flats. NOAA and the state of Florida manage the sanctuary.

NOAA’s mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Find us online and on Facebook.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
