Abstract

ABSTRACT The Hawaii Multiple Use Area (HMUA) belongs to the urban community of Chiquimulilla. It is located between the Chiquimulilla Canal and the Pacific Ocean at an average elevation of two meters above sea level, with an average annual temperature of 27 degrees Celsius (°C) and an average annual precipitation of 1,805.5 millimeters. It features five species of mangrove. This research was conducted in the period of September to October 2021, with the support of the National Forestry Institute (INAB) and the Wildlife Rescue and Conservation Association (ARCAS). Mangrove restoration projects have been carried out in the AUMH without an evaluation of their results. Therefore, the objective was to assess the restoration processes implemented in the area. Data on the survival of mangrove plants in the restored areas were obtained using simple random sampling and Pearson correlation. Additionally, the physicochemical parameters of interstitial water (temperature, electrical conductivity, hydrogen potential, and total dissolved solids) were analyzed. The survival rate of seedlings under each restoration technique (chinampas technique and Riley) used in the El Salado and El Papaturro areas was estimated, with results showing that the survival of red mangrove plants in the chinampas of El Papaturro was 26%, in the chinampas of El Salado was 42%, and with the Riley in El Salado was 71%, with the latter technique showing the best results. This study found that the physicochemical parameters do not influence the survival rate of red mangrove plants in the restoration areas.
