Estimation of standing volume of natural forest across different forest types in Yellapur forest division
Abstract
Forest plays a vital role in mitigating the climate change. Forest can act as a carbon sink and carbon source. The estimation of volume in different forest types act as an important variable to estimate the biomass accumulation and carbon sequestration potential of forests. The objective of the study was to estimate the standing volume in different forest types of Yellapur forest division by laying permanent plot. The total of 9 permanent plots, three plots each in dry, moist deciduous and semi-evergreen forest, each of 1ha (100 ×100 m) were laid out. The trees having girth at breast height30 cm within the plots were given number using paint. The total of seven sub plots in each forest types were selected from permanents plots for the enumeration. The observations on growth parameter (tree height, girth at breast height and girth at base), were recorded. The findings of the study indicated that the highest number of stems were recorded in semi evergreen forest (578 stems ha-1) and lowest was recorded in moist deciduous forest (439 stems ha-1). The study revealed that the maximum average height was recorded in moist deciduous forest (13.61 m). It was observed that higher basal area (47.21 m2 ha-1) and volume (612.33 m3 ha-1) was recorded in semi evergreen forest and the lowest volume was recorded from dry deciduous forest (269.86 m3 ha-1). There was a significant difference in basal area and volume across different vegetation types in Yellapur forest division.
