Easter rains bring relief to Doñana, but more rainfall is needed this spring

145.3 l/m2 have been collected during March, mostly during Easter, according to ICTS-Doñana data. Rains come late for wintering, but will still be useful for waterfowl breeding. The annual hydrological cycle, which runs from September to August, has already accumulated a precipitation of 404.4 l/m2. This exceeds that of the three previous years at this time, but still does not reach the historical average per cycle, which exceeds 500 l/m2.
