Multi-purpose uses of trees in the landscape seen from the road

Abstract

In rural areas at the present time, roadside trees and also trees in the wider landscape visible from the road, are normally planted for a narrow range of purposes. Consequently much of their potential value remains unrealised.

The objectives of this study are two-fold. They are to explore opportunities for planting trees by the roadside in rural areas and on land visible from the road in order to: 1) achieve multiple objectives, 2) enhance landscape values, thus increasing their overall value to the community.

These objectives are embodied in the Town and Country Planning Act (1977) Section 3(1), "Matters of National Importance". a) The conservation, protection, and enhancement of the physical, cultural and social environment. b) The wise use and management of New Zealand's resources.

In the past, environmental and landscape issues have not always been accorded due consideration. However, as Lovejoy explains, the importance of these issues must be recognised:

"Planning, particularly land use and landscape planning, is now basic for human survival”. (p. 3).

The revision of the Town and Country Planning Act in 1977 recognised the importance of environmental matters and gave them greater emphasis (4).

The purpose and characteristics of roads is discussed in Chapter Two. Trees are described in Chapter Three, and the full range of purposes for which they are planted is examined. Finally, their value by the roadside is assessed.

The findings of Chapters Two and Three are discussed in Chapter Four in order to determine the opportunities for multiple objective roadside planting, and also for planting in the wider landscape. The most important issues emerging from this are identified. Examples of recent plantings under the Beautiful New Zealand Scheme which illustrates these opportunities are described in Chapter Five. The present institutional framework is discussed in Chapter Six and the issue of implementation in Chapter Seven.
