Abstract. Wasis B, Saharjo BH, Putra EI. 2019. Impacts of peat fire on soil flora and fauna, soil properties and environmental damage in Riau Province, Indonesia. Biodiversitas 20: 1770-1775. Land fires set by communities can result in the death of flora and fauna, damage the soil, and cause smoke disasters. In this study, we focused on the burnt community land in Riau Province, where we conducted a soil analysis through purposive sampling to highlight the effect of the fires on the environment. Our findings showed that fires caused a decrease of peat soil thickness of 10-15 cm, and resulted in 100% mortality of soil flora and fauna. We found a significant increase in the Ca and soil pH after a fire, but total microorganisms, total fungi, and soil respiration are found decreased. Our results strongly showed that the soil and environmental damage of burnt peat soil on community land exceeded the minimum criteria to be classified as "environmental damage" as defined by Indonesian Government Regulation No. 4/2001 (PP No 4/2001) for the parameters of bulk density, porosity, pH, organic C, N, total microorganisms, total fungi, and respiration.

Forestry-drained peatlands occupy approximately 15 million ha in boreal and temperate zones. In Finland, they represent almost one-fourth of the total forest area. They are subjected to the same harvesting operations as upland forests. Although the soil deformation caused by timber harvesting is well documented in upland forests, the knowledge on the soil disturbance induced by the harvesting machinery on peat soils is still lacking. To address this, we collected soil samples from six peatland sites that were thinned using a harvester–forwarder combination. Peat samples were taken from the trails formed by the machinery and outside the trails to a depth of 10 cm. To assess the recovery of soil properties after the disturbance, we sampled sites along a chronosequence with respect to time since harvesting. Soil deformation under the machinery appeared to increase the bulk density and field capacity of peat and decrease its total porosity; however, disturbed plots and control plots started to resemble each other in their soil properties within 15 years. The results imply that peat soil is sensitive to disturbance but has a high recovery potential.

The relative abundances of arabinose, xylose, mannose, galactose, glucose, total pentoses, total hexoses and total sugars in 50 soil horizon samples derived from two groups of Canadian peat soil profiles have been correlated with five characteristic soil properties, namely, fiber content, pyrophosphate index, ash content, C:N ratio and cation exchange capacity. The correlation coefficients demonstrated that of the monosaccharides or sugars examined, glucose and total sugar contents correlated best with the five soil properties. The coefficients also showed that sugar analysis is as reliable as the five soil properties for assessing the degree of decomposition of peat. Sugar analysis, therefore, can be used to differentiate peats. Key words: Peat, monosaccharides, soil properties, correlation, decomposition

Greenhouse gas emissions from drained agricultural peatlands contribute significantly to global warming. In a laboratory study using intact cores of peat soil from eight different sites in Sweden, factors controlling the emission of the greenhouse gases nitrous oxide (N2O) and methane (CH4) were examined. Soil properties, and the abundance of the total microbial community (16S rRNA gene abundance), and genes encoding for functions controlling N2O emissions (bacterial and archaeal amoA, nirS, nirK, nosZI, and nosZII) were analyzed and compared against measured greenhouse gas emissions. Emissions were measured at different drainage levels, i.e., higher soil water suction values, since drainage is an important factor controlling greenhouse gas emissions from peat soils. The results showed that N2O and CH4 emissions were generally low, except for N2O emissions at near water-saturated conditions, for which three soils displayed high values and large variations in fluxes. Relationships between N2O emissions and soil properties were mainly linked to soil pH, with higher emissions at lower pH. However, specific assemblages of nitrogen cycling guilds that included nosZII, typically present in non-denitrifying N2O reducers, were detected in soils with low N2O emissions. Overall, these results indicate that both pH and biotic controls determine net N2O fluxes.
