Efforts need to be stepped up to map, track, and re-colonize these underwater meadows. Eagles 2017 Article The following is an excerpt from the full updated article. Field data were collected at the five potentially viable sites in order to evaluate habitat conditions and rank the sites with respect to habitat quality for eelgrass. In summer 2010 these sites were monitored to determine which would provide the most suitable habitat conditions for eelgrass test plantings.
