Forest management in the islands spans a wide range of objectives including watershed restoration and function, native forest restoration (often including wildlife considerations), invasive species control, timber plantation establishment and management and a variety of agroforestry systems.  Agroforestry intentionally combines agriculture and forestry to create integrated and sustainable land-use systems. Agroforestry takes advantage of the interactive benefits from combining trees and shrubs with crops and/or livestock.

Plant Information, Identification, and Databases

  1. Australian Tropical Rainforest Plants
    Note: many of these species may be invasive or otherwise inappropriate for use in the Pacific Islands Area – this is merely a potential reference for some species that may be typical in the Pacific Islands Area.

  2. Field Identification of the 50 Most Common Plant Families in Temperate Regions (Rutgers University) (PDF; 4.16 MB)
    A nicely illustrated key to selected plant families.  The document was developed for “temperate” settings but the broad plant family characteristics are applicable to PIA locations.  Some of the 50 families are not found in PIA, and there are many other plant families not represented.
