|Title:||Seeding and mulching + seeding effects on post-fire runoff, soil erosion and species diversity in Galicia (NW Spain)|
Vega, J. A.

|Abstract:||The effects of two different soil rehabilitation treatments on runoff, inﬁltration, erosion and species diversity were evaluated in a shrubland area in Galicia (NW Spain) after an experimental ﬁre by means of rainfall simulations. The treatments compared were: seeding, seedingþmulching and control (untreated). Rainfall simulations were conducted 9 months after ﬁre and the application of soil rehabilitation treatments. A rainfall rate of 67mmh 1 was applied for 30min to each runoff plot. Seeding signiﬁcantly increased plant species richness in the treated plots relative to the control plots, although it had no effect on diversity or evenness. Rehabilitation treatments did not signiﬁcantly increase soil cover or affect runoff and inﬁltration. Soil losses were low in all cases, varying from 75 6kgha 1 in the seededþmulched plots to 212 1kgha 1 in the untreated plots. However, there were no signiﬁcant differences in sediment yields between treatments. The percentage of bare soil appeared to be a critical variable in controlling runoff and erosion.|
