Analyses of limestone soils under shifting cultivation, involving the growing of sweet potatoes and laros (Colocasia escalenta) for 6-8 months and a natural regeneration period of 15-20 years followed by burning of the secondary forest, showed this system to be sound. The organic-matter content of the A1 horizon shows little variation during cultivation and regeneration, and the acidity of the top soil is directly related to exchangeable-Ca levels.

Abundance And Diversity

Abstract. Ihsan M, Puspitarini RD, Afandhi A, Fernando I. 2021. Abundance and diversity of edaphic mites (Arachnida, Acari) under different forest management systems in Indonesia. Biodiversitas 22: 3685-3692. Edaphic mites play crucial roles in maintaining ecosystem services that are essential to human needs. However, the conversion of natural habitats followed by agricultural intensification may adversely affect edaphic mites. The objective of this study was to investigate the influence of different management systems on edaphic mite abundance, richness, and diversity in tropical rain forests in Indonesia. There were five forest management systems, which were as follows: secondary forest, production forest (pine monoculture), and three agroforestry systems (pine + coffee, mahogany + coffee, and mahogany + new cocoyam). We established a transect containing five research plots for each forest management system. Litter and soil from each plot were collected from December to March 2021. Temperature, relative humidity, and pH of litter and soil, as well as litter thickness, were measured. We found that edaphic mite abundance, richness, and diversity in the secondary forest were similar to managed forests. However, the aforementioned variables were significantly higher in “pine” systems than in “mahogany” systems. Our analysis evidenced positive correlations between litter thickness and edaphic mite abundance, richness, and diversity. Our findings may assist in selecting the appropriate forest management systems to rationalize the conversion of secondary forests to production forests and agroforestry.

This study was aimed to identify the dominant species establishing during regeneration, their species diversity and whether selection thinning could enhance the regeneration of secondary forest species. Chittagong University Forest was selected for the study and harvested and unharvested sites of forest plantations were demarcated and set 30 quadratic plots (3m × 3m) for each site. Ten per cent selection thinning was done in harvested site although a little anthropogenic disturbance was noticed in both the plantations.  Regenerations were identified into species level and their numbers were counted. Shannon-Weiner diversity index for unharvested plantation was 2.21 and it was 1.45 for harvested plantation. Species evenness index was recorded as 0.81 and 0.74 for unharvested and harvested plantations respectively. Both the plantations did not show a significant difference in diversity of species. According to the Important Value Index (IVI) the dominant species in the harvested site were Acacia auriculiformis followed by Acacia mangium and Albizia lebbeck. In the unharvested site, IVI was the highest for Acacia auriculiformis followed by Aphanamixis polystachya and Lagerstroemia speciosa. In both the sites, Acacia auriculiformis had a significantly (p<0.05) higher number of regeneration in harvested plantations than those of unharvested plantations. Therefore, thinning has a positive impact on natural regeneration and Acacia auriculiformis is the best for natural regeneration in plantations.

Tree Crowns

Biological problems which may result from the use of heavy logging equipment are discussed. Scarification from logging rarely produces enough seedbed favourable to natural regeneration. Full-tree logging may cause nutrition problems by removing tree crowns from poor sites. Well designed studies of various kinds of logging systems are needed to assess their effects on the stand, soil and future regeneration. Studies of nutrient cycling in native forest stands might indicate some of the effects of full tree logging.

Mountainous Landscape

Belowground roles of agroforestry in climate change mitigation (C storage) and adaptation (reduced vulnerability to drought) are less obvious than easy-to-measure aspects aboveground. Documentation on these roles is lacking. We quantified the organic C concentration (Corg) and soil physical properties in a mountainous landscape in Sulawesi (Indonesia) for five land cover types: secondary forest (SF), multistrata cocoa–based agroforestry (CAF) aged 4–5 years (CAF4), 10–12 years (CAF10), 17–34 years (CAF17), and multistrata (mixed fruit and timber) agroforest (MAF45) aged 45–68 years. With four replicate plots per cover type, we measured five pools of C-stock according to IPCC guidelines, soil bulk density (BD), macro porosity (MP), hydraulic conductivity (Ks), and available water capacity of the soil (AWC). The highest C-stock, in SF, was around 320 Mg ha−1, the lowest, 74 Mg ha−1, was in CAF4, with the older agroforestry systems being intermediate with 120 to 150 Mg ha−1. Soil compaction after forest conversion led to increased BD and reduced MP, Ks, and AWC. Older agroforestry partly recovered buffering: AWC per m of rooted soil profile increased by 5.7 mm per unit (g kg−1) increase of Corg. The restored AWC can support about a week’s worth of evapotranspiration without rain, assisting in climate change adaptation.

Natural disturbances in European production forests are undesired from an economic perspective but are important drivers of biodiversity. The removal of damaged timber to restore economic value is accompanied by negative effects on various species groups, particularly breeding bird communities, and can hinder natural regeneration. However, little is known about the effect of postdisturbance logging on bird assemblages in winter when temperatures are low and food resources are unpredictable. We conducted fixed-radius point counts of wintering birds in forest stands logged or unlogged after windthrows and in mature forest stands to test our predictions that bird species densities and abundances (i) are lower in postdisturbance logged stands and (ii) depend on the amount of natural regeneration, (iii) which differs between logged and unlogged stands. Our generalized linear mixed model did not support the expected differences in bird abundance or species densities between postdisturbance logged and unlogged stands but indicated that mature forest stands harbor the highest bird abundances and species densities. The number of regenerated coniferous trees significantly positively affected wintering bird abundances in both postdisturbance logged and unlogged stands. Hence, the number of coniferous trees appears to be a main predictor of wintering bird presence.
