The Hackfalls Arboretum Catalogue documents an outstanding achievement. New Zealand farmer, dendrologist, and IOS member Bob Berry has amassed a collection of over 3,000 taxa at the homestead of his family farm in Tiniroto, near Gisborne, and now has published his database, including many photos of trees and close-ups of leaves.

This book is a thorough account of the 150-year tradition of Hillier’s and treats readers to the people, the places, and the plants that gave rise to this great nursery and gardens known throughout the world and shows that such success only comes through hard work, perseverance, and a love for what you are doing.  

Aubrey Streit Krug's review of IOS member Jack Phillips' book.

Many common native trees are just as beautiful as cultivated exotics. Since they have evolved with local conditions and are well adapted to their climate, they often require less maintenance and won't escape to invade a balanced ecosystem.
