Ecological Evaluation of a Beach Nourishment Project at Hallandale (Broward County) Florida. Volume II. Evaluation of Benthic Communities Adjacent to a Restored Beach, Hallandale (Broward County), Florida.
Abstract
Benthic communities adjacent to a restored beach at Hallandale (Broward County), Florida were analyzed and compared to similar communities at nearby Golden Beach (Dade County). Five sand stations and four reef stations were sampled at each locality along a transect from the intertidal zone through the second reef. This study assesses the postnourishment condition of sandy-bottom and reef-dwelling communities approximately 7 years after beach nourishment and offshore dredging. The study also provides prenourishment data for an impact analysis of a fill project underway at Hallandale in September 1979. Core samples at sand stations yielded 114 invertebrate species, not including nemerteans and oligochaete annelids. More than 90 percent of the fauna occurred at the two outer stations in densities of up to 17,144 individuals per square meter. Quadrat samples of reef biota showed a maximum abundance and diversity of corals, alcyonarians, and sponges in the middle and outer regions of the second reef. The reefs appeared in good condition, and showed no apparent effects from a 1971 beach nourishment project. (Author)
