Perennial: plant that lives for more than 2 years: island biogeography for species preservation. Us national parks become isolated islands of biodiversity and some species in them were. # of species increase with island area. # of species decreases with island isolation. # of species on island represents equilibrium btwn rates of immigration and extinction: earth"s terrestrial biomes.
