sustainable design principles - #4

maximise the use of local and sustainably sourced materials
I need to consider the source of materials used in a landscape project for several reasons: 
  1. using local materials (especially plants) where possible ensures a sense of place. The new landscape fits into its surrounds while supporting the local economy.
  2. less time, energy and money are consumed in transporting the material.
  3. materials are produced/harvested in a manner which is not detrimental to its source eg. river pebbles were not harvested from areas which would result in redirecting the course of a river; trees are managed to certified standards in the production of timber.
  4. using local plant species which are suited to the local and surrounding environment... more on that in future posts.
