Vegetation of the sand country bordering the Waitakere Range, Auckland: Piha Beach.

[First paragraph(s)...]
Sand has been laid along most of the west coast of North Auckland, mainly in long stretches such as at Ninety Mile Beach, Kaipara North Head and Muriwai. Piha Beach is one of the few places where sand has been deposited in a bay. This paper traces changes in topography and vegetation of this beach from 1940 to 1974.

The practice of forestry within Auckland's operating water catchment.

Part of Auckland's water supply is obtained from 16,190ha in the Hunua ranges. Some 7600ha of this area is suitable for production forestry. The desirability of forestry practice within an operating water catchment is discussed, experimental work being done is outlined and tentative conclusions drawn. Providing adequate safeguards are maintained there appears to be no reason why forestry should not be practised within catchments operated for domestic water supply.
