Stand performance of revegetation of post coal mining

Abstract

The success of revegetation can be monitored by an assessment of the performance of the revegetation stand. This study aims to analyze and comparing the performance of post coal revegetation stands conventional cropping patterns and hydroseeding planting patterns. The research location is revegetation area of PT. Adaro Site Tanjung Tabalong. The research took place for 2 months from data collection, analysis of data and reporting article. Data is collected using nested plot, the main plot size used is 10 m x 40 m. The main plot is divided into 4 measuring plots measuring 10m x 10m. The main plot measuring 10m x 40m was purposively placed on 2 locations of conventional cropping revegetation stands and 4 locations for revegetation stands of hydroseeding planting patterns. Data collected are stand dimensions data in the form of individual numbers, diameter and height of trees. The composition of plant species was analyzed by tabulation matrix, the percentage of plant growth was calculated based on number of plant growth/ha, stand diversity was assessed by the Shanon-Wiener index (H '), stand volume was analyzed by volume formula, plant health was analyzed qualitatively from observations of visualization of revegetation stand. The composition of plant species used in revegetation is 6 species. The percentage of planting success for conventional planting patterns is 93.5%, while the hydroseeding planting pattern is can’t be determined by the percentage of growth. The number of revegetated plants compared to the two cropping patterns has exceeded the established revegetation success rules (625 individuals / ha). Conventional plants have fewer plants/ ha than the hydroseeding pattern, but have a higher average diameter, height, stand volume and diversity index value. Based on visual observations, there was no difference in plant health between the two revegetation plots. The revegetation stand performance from the results of this study can be categorized as good
