Vegetation of Guam
Plant communities and vegetation resources of Guam have been studies by Fosberg (1960), Raulerson and others (1978), Mueller-Dombois and Fosberg (1998) and US Department of Agriculture (20002). According to these researchers, Guam hosts a diverse flora of over 600 species of vascular plants, including more than 100 species of trees. The distribution of vegetation is influenced by
two main factors, the sharply contrasting soil types between the north and south and anthropogenic (e.g. urban development and fire) and
natural (i.e. windthrow from hurricanes) disturbances.
