People will have a chance see the results of a decade of development at the Guthrie-Smith Arboretum when the 90ha site at Tutira, which now has over 20,000 trees, opens to the public on Sunday.
The arboretum spreads over the rolling hills bordering Lake Tutira and Lake Orakai and is planted with trees from New Zealand, Australia, China, Japan, the Himalayas, Europe, Mexico, North America, and Mediterranean.
Each group of trees is linked by walking tacks, with one of the most dramatic The Hanger, which follows through a 10ha hill-face area left largely untouched by human intervention for over 115 years.
The origins of the arboretum date back to when naturalist and farmer Herbert Guthrie-Smith, who farmed Tutira Station from 1882 to 1940, owned over 60,000 acres (24281ha) of land.
He died in 1940, and two years later his daughter Barbara Absolom donated 800ha for New Zealanders' benefit and, particularly, for educational and recreational purposes. The Guthrie-Smith Trust was set up to administer the land. The trust sold all but 80ha in 1997 and the money was used to develop the property. A 10ha block of Redwoods and pines was subsequently purchased.
