drought susceptibility

Notes on the influence of drought on the bush remnants of the Manawatu lowlands.

The data of Atkinson and Greenwood (1972) on drought damage to trees in 1969-70 in two bush patches in the Manawatu district are reassessed, and an index of drought susceptibility based on their data used to classify species into three categories of susceptibility. The results of this categorisation are compared with independent data on the effects of the 1972-73 drought on the nearby bush remnant at Ashhurst Domain. The behaviour of species in all three bush patches is shown to be similar.
