The effects of long-term reforestation on soil microbial communities and biomass are poorly understood. This study was conducted on two coniferous plantations: Cunninghamia konishii Hayata, planted 40 years ago (CONIF-40), and Calocedrus formosana (Florin) Florin, planted 80 years ago (CONIF-80). An adjacent natural broadleaf forest (BROAD-Nat) was used as a control. We determined microbial bio...

In this study the potentialities of ERS/ENVISAT-SAR multitemporal data for the analysis of the reforestation process over burned areas are investigated. The summer 2000 fire devastating a large part of the Castel Fusano pinewood (near Rome) is the selected test case. A first objective is to evaluate the capability of detecting the boundaries of the burned area only using SAR imagery and conside...
