| Zusammenfassung |
| Wildfires affecting forest ecosystems and post-fire silvicultural treatments
may cause considerable changes in soil properties. The capacity of different
microbial groups to recolonise soil after disturbances is crucial for proper
soil functioning. The aim of this work was to investigate some microbial soil
properties and enzyme activities in semiarid and dry Aleppo pine
(Pinus halepensis M.) forest stands. Different plots affected by a
wildfire event 17 years ago without or with post-fire silvicultural
treatments 5 years after the fire event were selected. A mature Aleppo
pine stand, unaffected by wildfire and not thinned was used as a control.
Physicochemical soil properties (soil texture, pH, carbonates, organic
matter, electrical conductivity, total N and P), soil enzymes (urease,
phosphatase, β-glucosidase and dehydrogenase activities), soil
respiration and soil microbial biomass carbon were analysed in the selected
forests areas and plots. The main finding was that long time after this fire
event produces no differences in the microbiological soil properties and
enzyme activities of soil after comparing burned and thinned, burned and not
thinned, and mature plots. Moreover, significant site variation was generally
seen in soil enzyme activities and microbiological parameters. We conclude
that total vegetation recovery normalises post-fire soil microbial
parameters, and that wildfire and post-fire silvicultural treatments are not
significant factors affecting soil properties after 17 years. |
