In Clam Bayou, less than 5% of the shoreline has a canopied red mangrove shoreline. Degradation of the red mangrove habitat was caused by recent hydrological impairment (2000-2006) exacerbated by hurricane damages (2004). Seasonal flooding and poor water quality resulted in the loss of large areas, which are now covered by standing dead trees. In 2006, a culvert was installed to relieve the hydrological impairment, but the biological components have not recovered and ecological function has not been restored. Specifically, in Clam Bayou, there were very few reproducing red mangrove trees until recently (first reproductive trees spotted in 2010). Without a source of propagules within the bayou, it is a “propagule limited” system (Lewis 2005). During the past few years (beginning in 2006) we have successfully planted red mangrove seedlings and propagules using volunteers and community members for four years. However, we have only covered a very small area of the total potential shoreline within Clam Bayou. We are proposing to continue our shoreline enhancement work by engaging members of the community and directing them to Clam Bayou to plant mangroves and to learn about the ecology and ecological services provided by a healthy lagoon/estuarine system.
