It's fitting to remember, this conservation week, that conservation has a long history in New Zealand, and individuals and groups in New Zealand have been promoting conservation for decades. "The Cultivation of New Zealand Plants" by Leonard Cockayne (1855–1934) is a great example. Published in 1923, this little gem lists New Zealand plants suitable for home, garden and park. When it was originally published, Cockayne was Honorary Botanist to the State Forest Service (the Department of Conservation not having been founded yet).
We've recently republished "The Cultivation of New Zealand Plants" as well as "The Vegetation of New Zealand" by Cockayne and the "Manual of the New Zealand Flora" (1906) by Thomas Frederick Cheeseman, one of the most authoritative texts on New Zealand botany.
