Large scale windstorms disturbed forest ecosystems in the Tatra Mountains in 2004, and were followed by a severe fire in 2005. A long-term study on the vegetation successional dynamics of the area was launched immediately after the 2005 event. Relevé plots were established under five different disturbance and management treatments: windthrow left, windthrow removed, hydrologically managed, burnt and reference. We used weighted Ellenberg's indicator plant values for ordination analyses of the following environmental gradients: light, temperature, continentality, moisture, acidity, nitrogen. Successional patterns depended on the management treatment. Heavily burnt areas were colonized by plants disseminated by airborn diasporas, mainly by Chamaerion angustifolium, less burnt or unburnt localities were settled by plants germinating from the soil seed bank or by plants surviving by root system. Nitrophilous weed vegetation invaded plots with increased moisture (fallen or standing overstory vegetation or irrigated by man-made system) and nitrogen (burnt or windthrow removal). The felled-area species were recorded in each plot. Abundant natural regeneration was observed in plots with increased moisture. The moss layer disappeared soon after the disturbance events. The results presented here refer to a very early successional stage, new insights into initial successional paterns are gained.

“…Ms explained 14 % of the high CO 2 flux class (2.11 µmol CO 2 m −2 s −1 ) ( Figure 3A). Similar results were found by Ryu et al (2009) in soils in California (U.S.A.), where Ms explained 14 % of the CO 2 flux variability and showed a negative correlation with CO 2 . Epron et al (2006) also found a negative correlation between CO 2 and Ms in a study on CO 2 fluxes from forest soils in French Guiana.…”

The harvesting system of green sugarcane, characterized by mechanized harvesting and no crop burning, affects soil quality by increasing the remaining straw left on the soil surface after harvesting, thus, contributing to the improvement of physical, chemical, and microbiological soil attributes, influencing CO 2 fluxes. This study aimed to evaluate CO 2 fluxes and their relation to soil properties in sugarcane crops under different harvesting managements: burned (B), Green harvesting for 5 years (G-5) and Green harvesting for ten years (G-10). For this, a 1 ha sampling grid with 30 points was installed in each area, all located in the Northeast of São Paulo State, Brazil. In each point, CO 2 fluxes were measured and the soil was sampled to analyze the microbial biomass, physical (soil moisture and temperature, mean weight diameter, bulk density, clay, macroporosity and microporosity) and chemical characterization (pH, organic C, base saturation and P). The CO 2 fluxes were divided into four quantitative criteria: high, moderate, low and very low from the Statistical Division (mean, first quartile, median and third quartile) and the other data were classified according this criterion. The Principal Component Analysis (PCA) was used to identify the main soil attributes that influence CO 2 fluxes. The results showed that G-10 CO 2 fluxes were 28 and 41 % higher than those in the G-5 and B treatments, respectively.The PCA analysis showed that macroporosity was the main soil attribute that influenced the high CO 2 fluxes.

“…Based on these observations, some studies examined the effects of forest thinning on soil CO 2 efflux with equivocal results ranging from positive effect on soil carbon release [14], negative effect [5,15] and no effect [16][17][18]. Others reported that intensive biomass harvesting may negatively impact carbon stocks in forest soil and vegetation [11], forest thinning did not have a significant impact on carbon stocks or fluxes [19], and remaining residues after harvesting increased carbon storage [20].…”

Forest thinning is a silviculture treatment for sustainable forest management. It may promote growth of the remaining individuals by decreasing stand density, reducing competition, and increasing light and nutrient availability to increase carbon sequestration in the forest ecosystem. However, the action also increases carbon loss simultaneously by reducing carbon and other nutrient inputs as well as exacerbating soil CO 2 efflux. To achieve a maximum forest carbon budget, the central composite design with two independent variables (thinning intensity and thinning residual removal rate) was explored in a natural pine-oak mixed stand in the Qinling Mountains, China. The net primary productivity of living trees was estimated and soil CO 2 efflux was stimulated by the Yasso07 model. Based on two years observation, the preliminary results indicated the following. Evidently chemical compounds of the litter of the tree species affected soil CO 2 efflux stimulation. The thinning residual removal rate had a larger effect than thinning intensity on the net ecosystem productivity. When the selective thinning intensity and residual removal rate was 12.59% and 66.62% concurrently, the net ecosystem productivity reached its maximum 53.93 t·ha −1 ·year −1 . The lower thinning intensity and higher thinning residual removal rated benefited the net ecosystem productivity.
