摘要

Forest fires affect (to various degrees) the properties of soils, and for this reason, they determine the post-fire regeneration and final restoration of the forest ecosystems. In this study, preliminary results of the project MoRe Forest: “MOnitoring the impact of restoration works in the post-fire forest environment in Greece” are presented with an emphasis on soils. More specifically, the focus was on assessing the impact of the restoration works on some soil properties in three burnt forest areas (located in Attica, Peloponnese, and Western Greece), for three different types of interventions (log-barriers, log-dams, and wattles) that enhance the biodiversity of local flora or fauna and accelerate the total ecosystem restoration. The soil properties chosen to determine were texture, pH, conductivity, organic carbon, and total (Kjeldahl) nitrogen. The drawn conclusions were based on the differences found between the eroded zone and the deposition zone for each intervention type of work. These zones are formed at the area between two consecutive restoration work units. It was found that the three types of restoration (taken as treatments) did not affect significantly the soil properties. However, when each intervention type was examined separately (paired t-test) significant differences were found for some properties. The wattles and log-barriers were the least influential interventions affecting only the conductivity of soil solution and clay parameter, respectively, whereas the log-dams significantly affected the conductivity, organic C, and total N. In the last case, the organic C content increased from 3.2 to 4.2% and conductivity from 1193 to 1800 μS/cm.
