Zusammenfassung:A new technique for sampling in tree canopies is described. "Sled sweeping" provides replicated estimates of relative insect, foliage or flower abundance in tree canopies in a homogeneous fashion, and can be replicated over many trees in rapid succession. We illustrate its use for estimates of diversity and the relative distribution of insects in tropical forests, as well as a measure of variability of insect abundance among tree canopies. We also discuss applications of the sled for floristic, pollination and taxonomic studies of epiphytes and other canopy phenomena.
