Last weekend my coworkers and I had the unique opportunity to get our feet wet in Mobile Bay and help our partners build a living shoreline. This amazing restoration project took place at Pelican Point near Fairhope, Alabama. Over 600 volunteers, including 300 airmen from Keesler Air Force Base, turned out early Saturday morning to help construct what in a few years will become an oyster reef teeming with life.

A living shoreline is an innovative approach to protecting an eroding shoreline, as well as creating habitat for the creatures that live in the bay. The Pelican Point living shoreline was created using structures called “oyster castles,” which are made up of interlocking concrete blocks. These concrete blocks weigh about 35 pounds each, so volunteers not only got to participate in building a reef, they also got a great workout!

A total of four oyster reefs will be built with 20,500 of these blocks when the project is complete. These four reefs will protect 329 feet of natural shoreline by helping to minimize erosion from boat wakes and strong waves generated by storms. Baby oysters, also known as spat, will attach to almost any hard substrate. These oyster castles will soon serve as a home for thousands of tiny oysters, and the reef will begin to come alive with all manner of marine life. Oysters are also a great way to improve water quality. Just one of these small bivalves has the ability to filter up to 50 gallons of water per day.

This restoration project is part of the 100-1000 Restore Coastal Alabama initiative. In the wake of the BP oil disaster and led in part by our own Bethany Kraft, the Alabama Coastal Foundation, the Nature Conservancy, Mobile Baykeeper, and the Ocean Foundation came together to launch the 100-100 Restore Coastal Alabama partnership as a first step in restoring the Alabama coast. The initiative will build 100 miles of oyster reefs and living shorelines to promote the growth of 1,000 acres of coastal marsh and seagrass beds. The Pelican Point project puts the 100-1000 initiative over the two mile mark for oyster reef restoration.

Ocean Conservancy would like to send out a big high five to the organizers of the Pelican Point restoration project, as well as to all the volunteers, military personal, contractors and organizations who participated. Keep up the great work, and we look forward to the next 100-1000 project!

Building a Mosaic of Restoration Projects for the Gulf http://blog.oceanconservancy.org/2012/07/19/building-a-mosaic-of-restoration-projects-for-the-gulf/ http://blog.oceanconservancy.org/2012/07/19/building-a-mosaic-of-restoration-projects-for-the-gulf/#comments Thu, 19 Jul 2012 14:38:52 +0000 Denny Takahashi Kelso http://blog.oceanconservancy.org/?p=1807 sea turtle mosaic

The BP Deepwater Horizon oil disaster harmed communities from Texas to Florida and damaged the Gulf ecosystem from the ocean floor to the surface across a vast swath of waters and shoreline. Restoring these damaged resources will require a comprehensive, Gulf-wide restoration plan that covers coastal environments, blue-water resources and Gulf communities.

Because wildlife like birds, fish and marine mammals move throughout the ecosystem making use of coastal, nearshore and offshore environments, effective restoration requires a holistic approach. For example, restoration efforts for oyster reefs or barrier islands in Texas should complement the work done in Alabama or in Florida so that the full suite of species and habitats can recover.

The state and federal officials responsible for creating such a plan, the Natural Resources Damage Assessment (NRDA) Trustees, are making decisions about how to spend the balance of the $1 billion committed by BP for early restoration. The decisions they make about early restoration and about the longer-term restoration program to follow have the potential to pay enormous dividends to the Gulf for generations.

To help the Trustees build an effective plan, a coalition of nonprofit groups, including Ocean Conservancy, has created a portfolio of 39 projects that reflect an integrated and Gulf-wide approach to restoration.

No doubt, other projects could have been included, but the point is to start a conversation about how we collectively fulfill our vision of a healthy and prosperous Gulf. This portfolio is more than a mosaic of projects; it also initiates an ongoing dialogue about how to most effectively restore the damage to the Gulf from the BP Deepwater Horizon tragedy.

Here are a few examples from the portfolio:

  • Sea Turtle Nesting Beach Conservation: The five species of sea turtles found in the Gulf are all either endangered or threatened. This project would protect their nesting habitat and nearby waters as well as provide for rehabilitation and care of injured sea turtles.
  • Large-scale Seagrass Restoration and Protection: Seagrass beds are essential components of healthy, productive and biodiverse aquatic ecosystems. This project aims to restore those areas damaged by vessel traffic, boom placement and other response and recovery efforts in ecologically sensitive areas.
  • Monitoring Marine Mammals, Sea Turtles and Bluefin Tuna: Additional observation and biological sampling in the Gulf will help scientists understand any lingering oil-exposure effects on these species.
  • Oyster Reef Restoration: Rebuilding reefs for juvenile oysters to colonize also provides nursery habitat for fish and nesting area for birds while protecting shorelines from erosion.
  • Threatened Coral Recovery: Restoration of shallow-water corals will provide critical habitat for fishes and other reef inhabitants, improving the health and resilience of this unique reef community.
  • Rebuilding Marsh and Barrier Islands: Marsh areas provide nursery habitat and help prevent dead zones by absorbing excess nutrients; barrier islands provide critical habitat for nesting birds. By restoring these ecosystems, a wide range of Gulf species benefit.
