NEXT LWLI Habitat Working Group September 2018 This group was created as an informal forum for the exchange of information about the Lake Worth Lagoon. We hope to increase our collective awareness of enhancement and monitoring efforts and discuss opportunities and methodologies to restore and protect Lagoon resources. Everyone with an interest in the Lagoon is encouraged to attend and participate. Though we do not vote on any issues, nor make recommendations as a group to any decision-making body, we do expect that ideas generated by these discussions will result in collaborative efforts that enhance the Lagoon and raise public awareness of its valuable resources.
