To evaluate the effects of avian-derived N deposition on forest C and N status, we investigated quantity and quality of litterfall, and chemical quality and N transformations in the forest floor from five sites that had been exposed to waterbird breeding colonies to differing degrees. The highest litterfall input of 2.6 t ha(-1) month(-1) was observed in the forest stand (Site 2) where intense bird breeding activity had been observed. Litterfall C/N was highest at the control site (no breeding activity) and decreased as the colonization stages advanced. Nitrogen concentration in litterfall and the forest floor was higher at those sites (Sites 3 and 4) where bird breeding had ceased and which represented the 'post-colony' situation, and consequently C/N and lignin/N of forest floor decreased. NH4-N pool size in the forest floor was higher at Site 2, probably due to ongoing input and mineralization of bird excreta. Nitrification rate and percent nitrification were highest at Sites 3 and 4. From these results we conclude that study sites exposed to bird colonies show signs of N excess even after colonies are abandoned.
