Pengaruh pembebasan terhadap riap diameter tegakan di hutan alam bekas tebangan di Kalimantan

This study was aimed to investigate the growth rate of residual stands of logged-over forest in West Kalimantan in response to competition. The analysis was carried out based on trees growth data from six permanent sample plots which comprised three treated plots (size of 80 m x 80 m each) and three untreated (control) plots (size of 50 m x 50 m each). The plots were established in 1993 (six years after logging) and re-measured in 1995, 1997 and 2000. The treated plots received liberation refinning of potential crop trees from competition of less undesirable neigbours. The results showed that liberation refinning could significantly affect to the growth rate in diameter (diameter increment). The diameter increments in treated plots were ranged from 0,43 cm/yr to 0,54 cm/yr in mean, whereas the diameter increments in control plots were ranged from 0,29 cm/yr to 0,37 cm/yr in mean. In logged-over forests, the post-logging treatment could be aimed to improve the growth of the residual stands in order to reduce the cutting rotation length. From the results, the bigger the diameter increment or the faster the growth, the shorter the cutting cycle.
