Q. Where can I find the oyster reefs and other BUG projects, such as the various islands and marshes?
A. There are currently a total of 172 acres of created oyster reefs. Click here for coordinates of the reef and other features of the BUG project.
Q.
What animals should we look out for at the new marsh?
A. Inter-tidal salt marshes are an ideal nursery area for marine
fish and shellfish as well as an important habitat for birds and
other wildlife. Observers of the new marshes have seen small finfish,
shrimp, crabs, various mollusks, small mammals such as marsh rice
rats, raccoons, dogs and cats, and over 100 bird species.
Q.
How long does it take to construct a marsh?
A. The marsh is constructed in different stages. First, the levee
is placed. Once this is done, shoreline protection is placed around
the levees to help protect them from erosion. When all the levee
material has settled, the marsh itself is then filled with material.
This too must settle before the area is vegetated. When the vegetation
is established, parts of the levees will be breached allowing for
full tidal interaction between marsh and bay. The entire process
takes approximately two to three years.
Q.
How much material has been dredged?
A. The dredge machines move an average of 1,300 cubic yards of silt
and clay per day. Since this expansion project began in December
1998, dredging crews have removed more than 16 million cubic yards
from the Houston-Galveston Navigation Channel.
Q.
What is the Beneficial Uses Group?
A. The Beneficial Uses Group (BUG) is an interagency team created
in 1990 to determine environmentally responsible and economically
sound ways to use materials dredged during the expansion of the
Houston-Galveston Navigation Channel.
Q.
How did the BUG form?
A. The Beneficial Uses Group is a subcommittee of the Interagency
Coordination Team (ICT). The ICT is a problem-solving group responsible
for the planning, engineering and post-project monitoring of the
dredged materials from the Ship Channel and bay.
Q.
What projects are the BUG overseeing?
A. The Beneficial Uses Group has a number of environmentally beneficial
projects underway, including: construction of 4,250 acres of inter-tidal
salt marsh; construction of a six-acre bird nesting and habitat
island; construction of an underwater berm to enhance habitation
for fish species; restoration of two previously existing islands:
Goat Island in Buffalo Bayou and Redfish Island in Galveston Bay;
and construction of new access channels and anchorages for recreational
boaters in mid-and lower Galveston Bay.
Q.
Why marshes?
A. Because they help the ecological system of the bay. Marshes help
wildlife by providing food, protection from predators, and spawning
and nursery habitats for many fish and wildlife species. Marshes
improve water quality by filtering out pollutants in the water,
helping to produce high-quality fish populations. Marshes prevent
erosion by absorbing wave energy in areas prone to loosing land
to the ocean. Marshes form buffer zones during storms and protect
lands from flooding by intercepting storm runoff and gradually releasing
floodwaters to downstream systems. Marshes provide many recreational
activities, such as opportunities for bird and wildlife observation,
hiking, hunting and fishing. Despite these benefits, either natural
threats or human impact destroys wetlands throughout the United
States. Marsh restoration is essential to maintaining the delicate
ecological balance along the coastlines in the United States and
around the world. Organizations such as the Beneficial Uses Group
are working to combat the destruction of wetlands and restore those
that have been lost.
