Soil respiration is the most important terrestrial source of CO2, which contributes significantly to climate change. A number of factors influence the size of soil respiration, the most important are the temperature and soil moisture, the type and condition of vegetation, the physical and chemical properties of the soil. Usually, not only the total soil respiration is changed, but also the proportion of its components, i. auto and heterotrophic components. In spruce forests of the High Tatra Mts. research areas have been established in the past for long-term monitoring of the CO2 emission dynamics from soil after natural disturbances, especially by wind, fires and nowadays mainly by bark beetle insects. The aim of this work is to contribute to the knowledge of the influence of different disturbance types on the size of soil respiration and its spatial characteristics, which is essential for optimal measurement design. Based on this knowledge, we state that the amount of CO2 emitted from the soil 14 years after being damaged by wind and insect pests is almost identical from these sites. At the same time, we found extraordinary large differences in spatial variability. While on the wind-damaged area the coefficient of variation of soil respiration is 63%, on the area damaged by wind is 41%. The rate of autocorrelation on the wind-damaged area is 10 m, but only 1.8 m on the site damaged by the bark beetle insects. High degree of spatial variability stresses the need to measure soil respiration on a finer scale and on a denser network, to make forest sequestering more reliable.
