The decline in the ecological function of mangroves is due to the reduced area of mangroves in Cengkrong Beach, Trenggalek Regency due to deforestation, to improve environmental quality, the researcher wants to examine the ecological function of mangroves in carbon absorption and carbon storage. The purpose of this study was to analyze the ecological function of mangroves based on the ability to absorb carbon dioxide and to analyze the carbon storage capacity of mangrove forest stands at Cengkrong Beach, Trenggalek Regency. This type of research is descriptive quantitative. The population in this study were all types of mangrove trees and litter in the research plot. Research on tree diameter, tree species and number, wet weight of litter was carried out randomly using simple random sampling. The data analysis technique was correlation test using SPSS 21. The results found 8 types of mangroves, namely Avicennia marina, Bruguiera gymnorrizha, Ceriops decandra, Ceriops tagal, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, and Sonneratia caseolaris. Carbon sequestration in Cengkrong, Trenggalek Regency has a total average of 33.963.42 tons/ha per year, equivalent to standing biomass of 20.136.6 tons/ha. The carbon storage capacity of trees is 9.262.9 tons C/ha, while the carbon storage capacity of litter is 225.48 tons C/ha.

“…Potential plants with high density can be ideal conditions for Javan langurs because tree crowns can overlap, which is helpful for moving from one tree to another (Sari et al 2020). Forest communities with vegetation structures such as natural forests can be a habitat for Javan langurs trees to provide protection, food, shelter and breeding (Diniyati 2015;Tolangara et al 2019).…”

Abstract. Wardhana HD, Muttaqin T, Aryanti N, Kurniawan I. 2022. Potential feeding plants of Javan Langur (Trachypithecus auratus) in the eastern slope of Biru Mountain, Batu City, East Java, Indonesia. Biodiversitas 23: 4216-4222. The Javan langur (Trachypithecus auratus) is an endemic animal in Indonesia and is located on the island of Java. Javan langur is an endemic primate and an officially endangered species. The purpose of this study was to determine the potential of forage plants in the area that will be used as a Javan langur release location so that it becomes one aspect of assessing whether or not it is appropriate for a Javan langur release. This research was conducted in Gunung Biru, Batu City, East Java, Indonesia. The method used is wandering quarter to determine the species composition. The analysis used is vegetation analysis, Morisita distribution index, Shannon-Wiener diversity index, Evenness index, Margalef wealth index, and Sorensen similarity index. The results of this study obtained 45 species of plants from the level of the pole and tree. Some of the dominant species are Homalanthus giganteus, Quercus sondaicus, Engelhardia spicata, and Trema orientalis. All types of plants found during the study were included in the Javan langur forage plants. The distribution index was clustered at the pole and tree level with a value of 0.081 at the pole and 0.106 at the tree. The diversity index was high at the pole level with a value of 3.272, while the moderate tree level with a value of 2.539. The species richness index showed high at the pole and tree level, with a value of 6.916 at the pole level and 4.461 at the tree level. The evenness of the pole-level vegetation is 0.874 and the tree-level vegetation is 0.789, so it includes a high evenness value. The similarity value between paths below 50% indicates that the similarity is low. Knowing that all species in the area are a source of forage for langurs, it can be said that the forage sources for Javan langurs are very abundant and it can be said that the area is very suitable for the release area of ??Javan langurs.

“…Tree species composition was considered to be an assemblage of tree species that characterized the forest vegetation (Ifo et al, 2016). Tree species encountered in each plot were counted, and the composition measures in Equations 1 to 5 were considered in the calculation of Important Value Species Indices (IVI): Density (D), Frequency (F), Relative Density (RD), Relative Frequency (RF) and Relative Dominance (RDn) following methods by Tolangara et al (2019) and Reshad et al 2020).…”

Tree species composition and diversity were assessed in Agoro-Agu Central Forest Reserve located in Lamwo district-Northern Uganda. Fifteen transects, each 2 km long, were established in the reserve. A procedure of nested quadrats was employed for a systematic sampling of mature trees, saplings and seedlings at 100 m interval(s). Vegetation analysis was conducted in Species Diversity and Richness (SDRiv) software. A total of 100 species of trees belonging to 36 families were recorded. The dominant tree species, also with high Importance Value Indices were Combretum molle G. Don, Albizia grandibracteata Taub. and Vachellia hockii De Wild. Tree species diversity was higher in the intact part (H'=3.46) than in the degraded part (H'=2.86). Lower diversity in the degraded part of the reserve could be due to human disturbance and resulting conducive condition for the early establishment of pioneer species during succession. The occurrence of mixed species with indicator species for both savannah woodlands and Afromontane tree species indicates that Agoro-Agu is an enriched forest for enhanced conservation. Management options that limit continuous degradations such as the enforcement of environmental laws, tree enrichment planting, and ex-situ conservation should be undertaken to restore the status of trees in the degraded part of the reserve.
