摘要: Abstract All vascular plants recorded in the lower Orongorongo Valley DSIR study area (1100 ha) are listed with notes on their status and distribution. Of 501 taxa, 355 native, 128 naturalised, 18 have probably been deliberately introduced or cultivated. Ofthe native 35% woody plants, but only 75 of these (or 60% taxa) common thus make up bulk vegetation structure. By contrast, less than 9% naturalised species all except two — gorse buddleia either uncommon rare. Annuals comprise 5.6% dicotyledon herbs 49% herbs. The history area, public use, animals, tectonic events, particularly earthquake-induced landslides mid-nineteenth century, outlined discussed relation to adventive flora. Exotic herbivores, especially possums (Trichosurus vulpecula), greatly reduced abundance some ...
