【 摘 要 】

Degraded mangrove areas can be restored and rehabilitated. In Indonesia, one of the main recommended of mangrove species for restoration of degraded was Rhizophora mucronata. The purpose of the study was to evaluate R. mucronata growth at first-year mangrove restoration at abandoned shrimp ponds, Pulau Sembilan village, Langkat, North Sumatera, Indonesia. The recovery area divided into three zones based on the salinity concentration, landward, middle, and seaward zones. The evaluation parameters of mangrove reforestation consist of seedling diameter and height, leaves number, and seedling growth rate. Results showed that 3 of 4 evaluation parameters of R. mucronata growth belong to landward zone, namely seedlings diameter, the number of leaves, and percentage of growth. By contrast, height R. mucronata seedlings dominated in the middle area. The study also found that the proper zone for mangrove restoration with R. mucronata was in the landward with 96% growth rate and 30 part per thousand salinity concentration. The present study, therefore, suggested that the recommended species for the degraded area was the prerequisite for successful mangrove restoration.
