Abstract Native, naturalised, pasture, and new grass
introductions are discussed in terms of concepts of moisture, temperature,
fertility, and utilisation gradients; characteristics of the New Zealand high
country environment; and their utility for introduction into low-input pastoral
systems. The perennial, long-lived habit of native grass is mimicked in
introduced grasses. Poa colensoi is the best native grass. but there is
a need for wider evaluation of seral non-tussock species. There is a greater
frequency of spreading habit and annuals in naturalised low-input species. The
"try it and see" and genotype/environment analysis are advocated for screening
new introductions.
