The aim of this research is to determine the structure and composition of mangrove forests in Hatusua State, Kairatu District, West Seram Regency. And vegetation analysis was carried out by collecting data on the type, number, diameter and height of trees. In this research, the path method was used by carrying out a 100% inventory. The measuring plot area for the vegetation growth level of Seedlings, Saplings and Trees is 20 m x 20 m, a total of 46 plots for a total area of 1.84 ha. The research results show that the mangrove forests in Hatusua State can be divided into two from inundation, namely the middle zone and the distal zone, where in this mangrove forest there is no proximal zone because there are no mangroves that face the sea. The stratification of Hatusua State's mangrove forests is simpler than that of mainland natural forests. Mangrove trees in Hatusua Country can reach a tree height of 15 – 25 meters, which are dominated by Rhizophora apiculata, Heritiera littoralis, Parmentiera cereifera, and Intsia bijuga. The Hatusua State mangrove forest diversity index value of 1.37 seedlings, 2.30 saplings and 1.36 trees is categorized as medium because the value 1 <H' < 3.

Agarwood (Aquilaria malaccensis) is a non-timber forest product commodity that has a high selling value. Indonesia is the largest agarwood producer in the world. By the end of 1990, Indonesia could produce more than 600 tons of agarwood annually. The research was carried out in the nursery of the Forestry Department, Faculty of Agriculture, Patimura University. This research was carried out from February to May 2024 to determine the effect of shade on the growth of gaharu seedlings (Aquilaria malaccensis). The percentage of shade supports the growth of (Aquilaria malaccensis). The experimental design used was a Completely Randomized Design (CRD) with 4 treatments, namely no shade, 50% shade, 65% shade, and 75% shade. The research results show that gaharu seeds are a semi-tolerant type, or a type of gaharu tree that can grow in open and shaded areas.

This study evaluates the success and failure of mangrove rehabilitation in Inner Ambon Bay, focusing on environmental factors, planting techniques, and habitat conditions. The research was conducted over 12 months, from May 2022 to April 2023, using descriptive quantitative and qualitative methods. Primary data were collected through field observations and interviews, while secondary data from relevant institutions were analyzed using Survival Rate and Growth Rate formulas. Out of 1,260 planted mangrove seedlings, only 29 survived, yielding a success rate of 2.3%. Failure factors include inadequate substrate, narrow intertidal zones due to reclamation, and wave disturbances. Proposed solutions include substrate modification, species zoning adjustments, and mechanical protection for seedlings. These findings highlight the importance of ecologically integrated approaches in mangrove rehabilitation programs to ensure long-term success.

Mangrove forests are one of the unique and distinctive forest ecosystem forms found in coastal areas or small islands as highly potential natural resources. Mangroves have high economic and ecological value but are vulnerable to damage if not utilized wisely. Mangrove ecosystems have important functions and benefits in coastal environments consisting of three main functions: physical, biological, and economic. Physical functions include erosion prevention, seawater intrusion barriers, wind barriers, and CO₂ reduction. Plant identification can be defined as an activity to reveal and establish the identity of plants, which in this case is determining the correct plant names and their proper place in the classification system. This research aims to identify mangrove species found in Hatusua State, Kairatu District, West Seram Regency. Based on the identification results of mangrove plant species at the research location, 15 plant species were found, divided into two groups. The true mangrove group consists of 5 species: Rhizophora apiculata, Sonneratia alba, Bruguiera gymnorrhiza, Bruguiera sexangula, and Avicennia lanata. The associate mangrove group consists of 7 species: Excoecaria agallocha, Xylocarpus moluccensis, Heritiera littoralis, Cerbera manghas, Dolichandrone spathacea, Aegiceras corniculatum, and Xylocarpus granatum. Additionally, understory plants were also found, such as Acrostichum speciosum, Acanthus ilicifolius, and Derris trifoliata. The results of this study indicate relatively high mangrove species diversity at the research location and can serve as a foundation for conservation efforts and sustainable mangrove ecosystem management.
