Influence of Tree Vegetation and The Associated Environmental Factors on Soil Organic Carbon; Evidence from “Kulon Progo Community Forestry,” Yogyakarta, Indonesia

This study aimed to assess the influence of tree vegetation and some environmental factor on soil organic carbon (SOC), which is part matter (SOM). Vegetation survey sampling were carried out in five stand types protected forest Kulon Progo Community Forestry, including Pinus (PN), Aleurites-Swietenia (AS), Swietenia-Acacia (SA), Melaleuca-Acacia (MA) Tectona-Dalbergia (TD). Tree composition characteristics (diversity, basal area, density, canopy height cover), SOC SOM analyzed using comparative analyses. The factors related topographic, edaphic anthropogenic aspects was performed by employing principal component analysis (PCA) redundancy (RDA). Our result confirmed that species among significantly different. Characteristically, PN relatively close MA, having similarities cover, area. While AS, SA TD similar each other diversity, density cover. Moreover, MA similarly hold less compared TD, while AS showed not different from TD. RDA high vegetation, where most influencing for an interaction below-stand utilization, cover directly proportional increased with decreasing utilization. We concluded small variations factors, selecting dense-canopy trees adaptive management utilization promised sequestration storage. findings provide fundamental information maximizing potential meet global payments ecosystem services contribute low-carbon development strategies emission reduction.
