Ecological Aspects of Climate Patterns within the Kaimai Ranges, North Island, New Zealand

Meteorological data from stations around and within the Kaimai Ranges and data from temporary sites are used to characterise the climate of the ranges. Lowland climate is warm temperate with ample rainfall but the upland region is cooler, wetter and frequently enveloped in fog. Frequent fog plays an important part in the climate of upland regions. By modifying light, moisture and temperature regimes fog may be a significant determinant of plant associations and may severely restrict growth. The absence of fog during prolonged drought may accentuate plant water stresses and appears to playa significant role in the occurrence and location of forest mortality.
