Description :
Input of terrestrial coarse particulate organic matter (CPOM : leaves and small wood,>1 mm) adds food resources and habitat to streams. The AA. investigated retention characteristics under base-flow conditions in 65 stream reaches in pasture, native forests and pine plantations in 5 contrasting New Zealand regions, using 3 CPOM analogues, namely 30 cm dowels, soaked ginkgo leaves and waterproof paper triangles. These differed significantly in geometric mean retention distance. A comparison with results from Spain showed similar relationships between retention distance of plactic CPOM analogues and dicharge under base-flow conditions.
