Evaluasi Pertumbuhan Anakan Mangrove Hasil Restorasi di Suaka Margasatwa Pulau Rambut, Kepulauan Seribu

Abstract

Pulau Rambut Wildlife Reserve (SMPR) is a conservation area located in the Thousand Islands. The status of a conservation area makes Pulau Rambut an area that must be preserved so its ecosystem functions can run optimally. One of the efforts to restore the function of the mangrove ecosystem in SMPR is to carry out the restoration. This study aims to determine the success rate of mangrove planting in the Pulau Rambut Wildlife Reserve (SMPR) and measure the growth and health condition of the planted seedlings. The data taken in this study were the number of seedlings, the height of the shoots of the seedlings, the diameter of the seedlings' stems, and the seedlings' health conditions. Mangrove planting at SMPR showed a low survival rate of 27,19% at Station I the northwestern part of the island) and 13% at Station II (northern part of the island). Station, I had an average height of seedlings of 31,08 cm, lower than the average height at Station II, which was 43.48 cm. The average diameter of seedlings at Station I (0,76 cm) is relatively the same as the average of seedlings at Station II (0,75 cm). In contrast, the proportion of healthy mangrove seedlings at both stations is relatively low (<11%).
