Canopy walkways are wooden platforms and connecting bridges that provide access to the upper canopy of mature trees. Canopy walkways were constructed at the Coweeta Hydrologie Laboratory in the Southern Appalachian mountains to study canopy arthropods and leaf area removed in deciduous forest stands. A pole pruner/plastic bag method was used to sample branches bearing leaves and their attendant arthropods. The arthropods were picked from the samples and the leaves were photocopied. Photocopies were measured for percentage of leaf area removed. An advantage of the canopy walkway method is that foliage and leaf-dwelling arthropods from the upper canopy can be sampled simultaneously, thus providing information on arthropod density per weight of leaves. Vertical stratification of arthropods can be studied by sampling from smaller platforms built higher in the crowns and by using pole pruners to sample the lower canopy.
