  • Hutchins, Sir David Ernest Hutchins (1850–1920)
    Hutchins, Sir David Ernest Hutchins (1850–1920) By the death of Sir David Hutchins, which took place at Wellington, New Zealand, on the 11th November, modern scientific forestry has lost one of its greatest exponents. Sir David’s professional life was singularly rich in opportunity and variety, and he has left his mark on the forests of many countries separated by a hemisphere. Sir David, who at the time of his decease had reached the allotted span of three score years and ten, received his professional education at the famous École Nationale des Eaux et Forêts, at Nancy, France. From there he proceeded to India, where he joined the Indian Forest Service, retiring after years of work which stamped him as a forester of outstanding qualities. From India he proceeded to South Africa, becoming Conservator of Forests in Cape Colony, a position from which he retired after holding the appointment for some thirty years. To him the Cape is indebted for its fine forests of eucalypts, now rapidly maturing, and yielding to-day a revenue to the Cape Colony of something like £20,000 per annum. From the Cape he proceeded to British East Africa, where he was Conservator of Forests for a number of years, and here, too, he introduced the growing of the Australian eucalypt. In retiring from the East African appointment Sir David, whose reputation as a forester of unusual capacity was known throughout the Empire, undertook quite a number of engagements as consulting forester, advising Governments and Administrations in various parts of the British Empire. His report on the forests of Cyprus and the prospects that modern scientific forestry had in an island, once rich in timber, but long denuded of its forest wealth, determined the future forest conditions in that possession.

Colonial Forestry at its Limits: The Latter Day Career of Sir David Hutchins in New Zealand 1915–1920 MICHAEL ROCHE School of People Environment and Planning Massey University PB 11-222 Palmerston North New Zealand 4442 Email: [email protected] ABSTRACT This paper explores imperial forestry networks by focusing on a single indi- vidual, Sir David Hutchins, who spent the final years of his life in New Zealand extolling the need for scientific forest management in the Dominion. Hutchins’ career had taken him from India to Southern Africa, to British East Africa and Australia, then finally to New Zealand. In New Zealand he advocated a colo- nial forestry model derived from his Indian and African experience. Whereas in Africa Hutchins was regarded as a champion of exotic afforestation, in New Zealand he was closely identified with indigenous forest management, further reinforcing Sivaramakrishnan’s ideas about how colonial location reshaped the appearance of scientific forestry. Hutchins focused much attention of the Kauri (Agathis australis) forests but encountered unexpected opposition and resist- ance from settler farmers, local politicians, and the local scientific community such as it was.

  • Interpreting Exotic Plantation Forestry in 1920S New Zealand
    (RE)INTERPRETING EXOTIC PLANTATION FORESTRY IN 1920S NEW ZEALAND MICHAEL ROCHE School of People, Environment and Planning, Massey University, Private Bag 11-222, Palmerston North. [email protected] Abstract Environmental historians who have contributed to the understanding of ‘eco- nationalism’ in New Zealand and within the sub-area of forest history have shown how deforestation produced a preservationist impulse and an exotic afforestation response to timber famine. My own work, in partial contrast, has tended to explore the largely unsuccessful efforts at indigenous forest management for production in the nineteenth century as well as suggesting that the large-scale afforestation boom of the 1920s and 1930s was a departure from the anticipated direction of state efforts when the Forests Department was established in 1919. Previously I have argued that the New Zealand State Forest Service under its first director L. M. Ellis initially favoured an orthodox state forestry model anchored on sustained-yield management of indigenous forests, and only later turned to large-scale exotic plantations, in order to forestall a projected timber famine by 1965, and to buy time to enable the mechanisms for regenerating indigenous forests to be understood. This paper looks more closely at Ellis’ initial statements about the role of plantation forestry and suggests that a partial change of interpretation is needed. Keywords: state forestry, historical geography, environmental history, afforestation, New Zealand. Introduction This article grows out of some of the differences in, emphasis on, and interpretations of New Zealand’s forest history that exist in the publications of New Zealand historians and my own writing as an historical geographer working in the field typically labelled ‘environmental history’.

  • Edward Phillips Turner: the Development of a ‘Forest Sense’ in New Zealand 1890S to 1930S
    Proceedings 6th National Conference of the Australian Forest History Society Inc, Michael Calver et al. (eds) © 2005 Millpress, Rotterdam, ISBN 90 5966 026 9 Edward Phillips Turner: The development of a ‘Forest Sense’ in New Zealand 1890s to 1930s Michael Roche School of People Environment and Planning, Massey University, Palmerston North, New Zealand Peer reviewed contribution Keywords: Phillips Turner, New Zealand, forest sense ABSTRACT: Edward Phillips Turner served as the second Director of Forests in New Zealand from 1928 to 1931. This was the culmination of a long public service career dating back to the 1890s. Although his formal qualifications were in surveying in many ways Phillips Turner became a forester. As such his career is a window onto changing official attitudes to forests and forestry in New Zealand from the last decade of the 19th to the first decades of the 20th century. This paper will consider events that drew Phillips Turner towards forestry, briefly discuss his main interests, and conclude with some observations on his post-retirement reflections on the management of forests in New Zealand. 1 INTRODUCTION A brave life; a true soul; an eye for the skies; a carriage distinguishing him in the forests of the world through which he trudged. Such was Edward Phillips Turner, gallant gentleman, surveyor, forester E. H. F. Swain I nominated Edward Phillips Turner for inclusion in The Dictionary of New Zealand Biography but he did not make the final selection. As Secretary of Forestry (1920 to 1928) and as Director of For- ests (1928 to 1931) he was regarded as a gentleman and he would have doubtless taken this rebuff with dignity.

  • 'Good Forest' in Kenya, C.1890-1963
    1 The pursuit of the ‘good forest’ in Kenya, c.1890-1963: the history of the contested development of state forestry within a colonial settler state. Ben Paul Fanstone University of Stirling PhD History Submitted 27th October 2016 Author’s declaration The work contained in this thesis is entirely my own. The views expressed are entirely my own, and not those of the University of Stirling. 3 Abstract This is a study of the creation and evolution of state forestry within colonial Kenya in social, economic, and political terms. Spanning Kenya’s entire colonial period, it offers a chronological account of how forestry came to Kenya and grew to the extent of controlling almost two million hectares of land in the country, approximately 20 per cent of the most fertile and most populated upland (above 1,500 metres) region of central Kenya . The position of forestry within a colonial state apparatus that paradoxically sought to both ‘protect’ Africans from modernisation while exploiting them to establish Kenya as a ‘white man’s country’ is underexplored in the country’s historiography. This thesis therefore clarifies this role through an examination of the relationship between the Forest Department and its African workers, Kenya’s white settlers, and the colonial government. In essence, how each of these was engaged in a pursuit for their own idealised ‘good forest’. Kenya was the site of a strong conservationist argument for the establishment of forestry that typecast the country’s indigenous population as rapidly destroying the forests. This argument was bolstered against critics of the financial extravagance of forestry by the need to maintain and develop the forests of Kenya for the express purpose of supporting the Uganda railway.

  • Sir David Hutchins and Kauri in New Zealand
    Sir David Hutchins and kauri in New Zealand Michael Roche School of People Environment and Planning, Massey University, New Zealand Key words: kauri, Sir David Hutchins, New Zealand Introduction The kauri (Agathis australis), found only in New Zealand, is one of 21 species comprising the genus Agathis that along with Araucaria and Wollemia make up the Araucariaceae family. Mature kauri is notable for its massive almost cylindrical branchless trunk reaching over 13 metres. Tane Mahuta in Waipoua forest estimated at 1500 years old, is the largest living kauri. It has a girth of 13.77 metres, a trunk height of 17.68 metres, a total height of 51.5 metres and a volume of 244.5 cubic metres (Halkett and Sale 1986, p.173). The species is currently found in the North Island of New Zealand as far as 38ºS or approximately a line drawn from Kawhia to Maketu. Kauri formed the basis of a spar trade from the 1820s to 1850s and efforts were made to reserve kauri forests for Royal Navy purposes when New Zealand was colonised by the British in 1840. A Conservator of Kauri Forests was appointed as early as 1841 but he was accidentally drowned and no replacement was ever made. Kauri sawmilling was an important 19th century industry. The timber was highly valued and was the one species to command colony wide sales. It was also exported in quantity particularly to Australia. The Kauri Timber Company established in 1888 which became the dominant player in the industry was Melbourne based. In 1885 Thomas Kirk the Chief Conservator of Forests estimated that kauri would be exhausted in 26 years.

  • Forestry and Forest Governance: a Brief Interpretive History
    International Forest Fire News (IFFN) No. 39 (January–June 2010), p. 2–19 ISSN 1029-0864 (web) Forestry and Forest Governance: A Brief Interpretive History “The Forester is a soldier of the State, and something more …” Sir D.E. Hutchins (1916)1 As long as humans have lived in or around forests, they have practiced means to govern their usage. Customary law is thick, empirical, and tenacious. But the modern epic of forestry emerged in 18th century Europe. It hammered ancient lore into new forms on an Enlightenment forge, made a devil’s bargain with the state, and during Europe’s global sprawl during the 19th century, became an instrument of imperial rule. It rose during the colonial era, and it has fallen with the decolonizing impulses that have succeeded it. The former lasted 50-80 years; the latter, still underway, enjoyed a brief revival in the postwar years and now promises a similar cycle of declension. Like the forests they oversee, institutions of forestry, it would seem, grow, mature, either senesce or are felled, and then regenerate or die. Folk Customs and Agronomic Concepts Europe’s notions of forest and governance matter especially because they have spread, for good or ill, throughout the Earth. Prior to its Enlightenment reformation, Europe had basically two notions of the woods. One was that wooded wildlands – dark, unbroken and uncultivated – were dangerous places full of masterless men. The English term “savage”, for example, derives from the Norman French sauvage, which derives from the Latin silva, or woods. A savage was someone who lived in the forest and by the chase, seemingly without a fixed residence or social order.
