Flowering Records of Some Sub-Alpine Trees and Shrubs at Arthurs Pass, New Zealand
The flowering periodicity and intensity of some subalpine trees and shrubs at Pegleg Flat, Arthur's Pass National Park, was recorded from 1981/82 to 1984/85. Moderate to heavy flowering of most species in 1981/82 was followed by two years of little or no flowering in 1982/83 and 1983/84; almost all species observed flowered heavily in 1984/85. No clear correlation was found between flowering intensity and mean summer temperatures of the previous growing season, when flower buds were initiated.
