2 CABE Space Design Scholarship Designing a compatible treescape Objective: To undertake research to enable the production of best practice guidance in the principles and technologies associated with design, establishment and compatible longevity of trees planted in urban, hard landscaped open space.

4 CABE became one of the logs on the coalition’s quango bonfire

5 Tree people like talking to tree people

6 The arboricultural profession has failed to deliver a sustainable urban treescape… …Why?

7 We need to plant less trees in our urban environment.

8

9 Tree officers should spend less time looking at trees

10

11 Arboricultural consultants should invest more time in selling the principles of arboriculture to their clients and to other professional disciplines

12

13 Our research organisations need to be more focussed on topical issues, providing the practitioner with credible evidence of the value and viability of the urban treescape

14 Our professional bodies are failing their membership in their duty to raise the profile of our profession in the political and policy making arenas

20 Root system of an open grown tree

21 A daunting density and complexity of constraints

22 Too frequently this is the norm for the tree pit spec.

23 Bespoke species selection and bespoke pit design for each site

24 No vision No provision No chance!

25 Soil volume standards adopted as policy

26

27 Root deflectors direct roots to growing medium below and prevent conflict with paved surface

28 Rainwater from adjacent roofs is directed into tree pits

30 Millennium Park, Chicago A impressive feat of engineering creates a complex blend of architecture, art and nature

31

32

33 Linear crating systems provide the tree with in excess of 20 cubic metres of growing medium beneath the pavement for each tree

36 We need to plant less trees in our urban environment. Promote trees at design stage as a critical element of urban infrastructure Deter numbers driven political agendas Invest resources wisely – make better provision for fewer trees Design bespoke tree pits that are integrated with other infrastructure and compatible in the long term

37 Tree officers should spend less time looking at trees Play a more strategic role within the organisation Raise the profile of specialist services Influence policy and strategic objectives Adopt minimum soil volume standards (SVS) as policy

38 Arboricultural consultants should invest more time in selling the principles of arboriculture to their clients Invest in education of the user to promote the service Secure the respect of other disciplines and work along side them Promote the benefits, particularly financial ones, to sell the principles

39 Our professional bodies are failing their membership in their duty to raise the profile of our profession in the political and policy making arenas Two way process – members need to get involved with their organisation We need to be recognised as a credible profession that has a will to influence policy at a national level Duty to promote the profession to the member’s customers

40 Conclusions Latest technology and design enables compatible integration of grey, blue and green infrastructure Its implementation requires greater synergy between the multiple disciplines involved in urban design, construction and management There is considerable scope to further develop the concept of ‘Sustainable integrated infrastructure (Sii)’

41 Look outside the tree pit Sii –The Future Sii – The Future
