forest fire and soil erosion


Hello from Praia De Barra again!
Last week we left the cool coast behind us to drive deeper inland. On our way we picked up Jacob from the Aveiro Unversity who led us the way into the carboniferous, on winding roads up the mountain hills covered by eucalyptus and pine forests.
To be more precise: Eucalyptus globulus and Pinus pinaster forests which were planted mainly for the paper industry. The natural forest would mainly consist of Quercus suber (cork oak). Jacob told us that since in the last years the frequency and number of forest fires has increased, he was able to get funding for his research on soil erosion after severe forest fires. Togehter with PhD-students he not only monitores the extent of soil transport from the bare and burnt hill slopes but also the re-growth of vegetation.


That day started of very warm; but only shortly after we had started our "guided tour" a cooling thunderstorm built up and gave us quite some millimeters of rainfall.....
Jammer, that this didn't occur in ower own catchments - some people with very little discharge (greetings to Chris ;) ) would have been very delighted indeed. We made the best out of it (see photo) and continued our excursion with some nice fresh "after-thunderstorm" air.
lots of greetings,
Vanessa
