Tree Diversity: New Solutions To Current Homogeny and Loss
Summary
Tree diversity concepts are becoming more critical within communities and among tree health care providers. This presentation will concentrate on new ideas from research attacking tree diversity issues in community forest and landscape management. Tree diversity measures are a combination of the number of different species (richness) and their abundance (evenness). In many communities, species numbers alone are considered to be the same as diversity. Across North America, Europe, and the Pacific Rim, cities are undergoing a number of tree diversity-related changes including species and family homogenization and loss, structural diversity and ecological volume loss, genetic diversity loss, and tree habitat loss. To counteract these changes, simple enrichment planting programs have been proposed and implemented— some of which tend to make diversity loss problems even greater. In addition, the balance within tree diversity management remains compromised by reducing cost (ease) of maintenance and associated loss of tree provided benefits. This presentation will discuss tree diversity definitions, the three types of tree diversity (spatial, taxonomic, and genetic), and provide a number of real solutions to tree diversity change and loss problems.
