Abstract

The Wailukum Mangrove Ecosystem requires a community based environmental management strategy. The purpose of this study was to analyze the characteristics of mangrove roots and stems in medium tide zones, the dominance index of Teredo navalis L and environmental management strategies in the era of the COVID-19 pandemic. This type of research is a case study. The research location is divided into two points, namely in the North and South. Sampling using the line transect method. Root and stem samples were observed using the quadratic method. The results of this study found that there are three types of mangroves that live in the medium tide zone, namely Rhizophora mucronata (Lamk.) Rhizophora apiculata and Rhizophora stylosa Griff. Characteristics of roots and stems have gaps and brittle easily. The dominance index of Teredo navalis L on the roots and stems is in the low category with the index range 0.01-0.62. Strategies that need to be used for environmental management of mangroves in Wailukum, East Halmahera Regency, are to open employment opportunities for the community, organize socialization and training of silvofishery systems for workers, make regulations to control community-based mangrove use and monitor violations of mangrove management.
