Abstract

Climate change causes forest fires that impact land cover damage, which can cause damage to soil properties and disrupt hydrological characteristics such as loss of spring or discharge depletion. This study aimed to assess the influence of land cover and rainfall on soil physical properties and spring discharge in the Cempaka Forest area. The study was conducted on three land covers, i.e., shrubs, pine, and non-timber forest products (NTFPs) in the Cempaka Forest area, Curah Tangkil Block, Pasuruan Regency, East Java Province. The measured parameters were soil bulk density, permeability, porosity, infiltration, daily rainfall, and spring discharge. Data analysis used analysis of variance (ANOVA) test at a 5% level, correlation test, and regression. The results showed that differences in land cover had no significant effect on soil physical properties. The correlation and regression results between rainfall and spring discharge showed that rainfall influenced spring discharge by 4%. The correlation and regression results in the medium-heavy rainfall categories influenced spring discharge by 38%.

Abstract

This study contributes to understanding ecological changes in land use following slash-and-burn land clearing. This study aimed to compare the richness and density of plant species and soil fertility in farmland cultivated for one year (1 Y), three years (3 Y), and five years (5 Y) after slash-and-burn, with the conditions in the secondary forest (SF) in Berau Regency of East Kalimantan. Understory plant taxon types, numbers, and soil organic matter were measured in each region using a series of nested plots. The size of each observation plot was 20 x 100 m. Data on understory vegetation composition was collected using 1 x 1 m mini plots at 20 sampling points and divided into five blocks, with a 10 m spacing between sampling points on each property. Understory vegetation species and cover percentage, litter cover percentage, open soil percentage, and soil fertility were measured for each observation plot. The results showed that the land cover percentage increased each year during the 5 years transition from secondary forest to farmland. Furthermore, within the 5 years, there was a change in understory species, particularly the presence of grasses and sedges at 3 and 5 years after the land use change. However, the transition from secondary forest to farmland within 5 years did not alter soil organic matter and total nitrogen.

Abstract

Forest fires have become a vital issue causing various hydro-meteorological disasters. Many parties have carried out efforts. This study aimed to analyze the impact of land covers due to reforestation on infiltration rate and other soil physical properties related to hydrological conditions. The research was conducted in the Cempaka Forest area. There are four observed land covers, i.e., Timber Forest Products (TFP), Non-Timber Forest Products (NTFP), Pine, and Shrub. The results showed that land cover significantly affected the infiltration rate (p <0.05). The infiltration rate of Pine was not significantly different from NTFP but significantly different from TFP and Shrubs. The infiltration rate of Pine, NTFP, TFP, and Shrub land cover was 76.2 cm hr-1, 48.1 cm hr-1, 32.7 cm.hr-1, and 40.0 cm hr-1, respectively. The infiltration correlated with soil bulk density at two depths (0-15 cm and 16-30 cm) with r values of 0.614 and 0.595, respectively. Infiltration rate also significantly correlated with water content at pF 0 and pF 2.5 in the second soil depth. Additionally, soil bulk density is correlated with soil particle density with r  = 0.621. Soil particle density also correlated with clay content with r equal to 0.726.
