Plantations development in KPH UPTD Boalemo Unit V area should be supported by community readiness and land suitability. This study analyzed the potential of masoyi plantations in the UPTD KPH Boalemo Gorontalo Unit V based on community readiness and land suitability. The level of community readiness was measured through in-depth interviews with key informants. Land suitability analysis was carried out using species matching method on the plant growth requirements of masoyi. Land characteristics were obtained from secondary data, direct field measurements, and soil analysis. The results showed: 1) community readiness is at level seven to nine; Ayuhulalo Village, Bendungan Village, Botumoito Village, and Rumbia Village have the highest community readiness, 2) land suitability is divided into: suitable 15.93%, moderately suitable 53.82%, and 24% unsuitable, 3) an area of 22,644 ha have the potential for development of masoyi plantation because it has a high level of community readiness and land suitabiliy level at moderately suitable, 4) an area of 7,041 ha is a priority area for the development of masoyi because it has a high level of community readiness and land suitability class at suitable, 5) Bendungan Village and Butomoito Village have the best community readiness and land suitability, 6) production forest area is dominated by marginally suitable land; land improvement/ manipulation is needed towards the limiting factors to support successful planting.
Natural regeneration depends on surviving propagules in the soil, seed sources from a surrounding landscape mosaic, and dispersal agents. We compiled and analyzed four sets of case studies varying in degree of disturbance, for secondary forests recovering from logging, fire, and conversion to agroforest in Sumatra or Kalimantan (Indonesia) on mineral and peat soils. Data on tree species diversity, wood density frequency distribution (indicative of successional status, databases with over 6000 species exist), and dispersal modes were compared with those for less disturbed comparator forests for the same landscapes. Undisturbed lowland dipterocarp forest in Kalimantan had close to 200 species of trees of more than 10 cm diameter at a 1 ha sample scale (and 450 at a 10-ha scale), regulation-based logging had little impact. Still, after the repeated fire a sample area of 2 ha was needed to reach the same species numbers. After forest conversion to low-management-intensity rubber agroforest, 50 tree species were found at a ha scale and close to 100 species in 3 ha. Peat swamp forest in Kalimantan and the Sumatra forest samples had close to 100 species in 1 to 2 ha. The Kalimantan forest after a repeated fire had a markedly higher fraction of low-wood-density trees (40%), but otherwise, all forests sampled were similar in overall wood density profiles. Logged-over forest managed by community (village forest) and rubber agroforest in Sumatra contained larger fractions of heavy-wood-density trees (including rubber). The majority of trees (50-70%) had birds, bats, and primates as dispersal agents in all sites. Logged-over forests on mineral soil had higher fractions of autochorous species (15%) compared to other sites. Anemochorous (wind-dispersed) species were most common (20%) in undisturbed lowland Dipterocarp forest and peat swamp forest recovering after logging and fire. Comparison between secondary forests and agroforests showed the influence of farmer selection regarding what is allowed to grow beyond the pole stage. Wood density and seed dispersal profile can be used as degradation indicators of species assemblages across various disturbance levels and types. They can also reflect the habitat quality of the surrounding forming restoration options.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
