KEYWORDS:

habitats, community structure, silviculture, ecology, biomass, resource management, disturbance, ecosystems, invertebrates

PURPOSE:

To provide data on the abundance and diversity of litter and bark-dwelling arthropods as ecological indicators of forest conditions. The bark arthropod data were also collected to provide information on the potential food availability to bark-gleaning birds.
