Masigit Kareumbi Game Reserve (MKGR) is a conservation area managed for the protection <br /> <br /> and utilization of biological resources, including hunting tourism. One of the hunted animals <br /> <br /> developed is the javan deer (Rusa timorensis). However, the presence of invasive species is at <br /> <br /> risk of decreasing the availability of feed for the javan deer, so managers must supported the <br /> <br /> needs of feed from outside the region. The handling of invasive plant problems needs to be <br /> <br /> supported by adequate information on ecological aspects, including the association of invasive <br /> <br /> species with other plants. This study aims to determine the species of feed and non-feed that <br /> <br /> associate most negatively with invasive species as a recommendation in increasing the <br /> <br /> availability of deer feed while controlling the presence of invasive species. Associations occur <br /> <br /> because of the attraction between species to live within a community. This association can be <br /> <br /> positive and negative. Research on this association is done in Cluster I area of hunting area <br /> <br /> planning with an area of 200 ha. The data collection of vegetation analysis was conducted on <br /> <br /> 60 plots measuring 400 m² spread over natural forest, secondary forest, and open area for <br /> <br /> determined INP species and Diversity Index (H’) of feed plants. The highest diversity is in <br /> <br /> natural forest (H’= 3,048), open area (H’= 2,872), and secondary forest (H’= 2,446). Invasive <br /> <br /> species tend to have the highest INP in secondary forest (1,399), natural forest (1,262), and <br /> <br /> open area (0,443). Based on the highest INP invasive species, selected Ageratina riparia and <br /> <br /> Clidemia hirta for the association. The association analysis was done through the 2x2 <br /> <br /> Contingency Table, then calculated its association strength using the Ochiai Index (OI). The <br /> <br /> strength of the association lies in the range 0-1, with 0 having very low association strength <br /> <br /> and 1 having very high association strength. The selected species are the types associated <br /> <br /> negatively with the invasive species and have high associative strength. Thus, it was found that <br /> <br /> the most associated plants associated with Ageratina riparia were Etlingia coccinea (1), <br /> <br /> Oplismenus compositus (1), Clidemia hirta (0,756), Austroeupatorium inulifolium (0,926), <br /> <br /> Lantana camara (0,707), Melastoma malabathricum (0,5), and Rubus moluccanus (0,5). Some <br /> <br /> of the most associated with Clidemia hirta is Oplismenus compositus (0,756), Carex baccans <br /> <br /> (0,756), Austroeupatorium inulifolium (0,535), Schima wallichii (0,535). Based on this <br /> <br /> information, to increase the availability of feed for javan deer, needs to be enrichment with <br /> <br /> species Oplismenus compositus, Melastoma malabathricum, Rubus moluccanus, Carex <br /> <br /> baccans, and Dysoxylum arborescens because in addition to having high OI value and the <br /> <br /> species is not classified as invasive species in the area of TBMK.
