[CANUFNET] Urban Trees Are Infrastructure--Green Infrastructure (again)

Mon Feb 22 20:18:04 EST 2021

Just as a point of history, my belief (I could be wrong about this) is that the term "green infrastructure" was only adopted rather recently in the Clean Water Act in the U.S. by the USEPA and is used primarily for CWA regulations and permitting and thus has a rather heavy stormwater management focus. A similar phenomenon has occurred with the term Low Impact Development--it is frequently used very narrowly for stormwater management facilities. My recollection is that "green infrastructure" has been in use since the 1990s or perhaps earlier in the broader sense of infrastructure--i.e., the foundational support system for something, often cities or more broadly, life on earth. I have noted that virtually everyone defines it before talking about it, perhaps realizing that the term is used in a variety of contexts for different purposes. I know I certainly do!

One could argue that the confusion makes the term less useful. Nonetheless, the concept has been found useful for emphasizing that trees and soils etc. do not need to be wiped away in order to build something, but are instead a critical foundational system. Whether this helps protect trees... I suppose the jury is out on that one. -Susan Day

Dear Tenley, Ian, Alex and Erna:

It is always interesting to present provocative thoughts to see where the resulting dialogue leads.

I follow the postings on canufnet religiously as there are often interesting questions posed and answers  / opinions offered.

I am actually located in Switzerland and involved with European Urban Forestry and Arboriculture as well as remaining active in the US arboricultural / UF community and I have yet to see appreciable results from adopting the language preferred by Planners / Architects / Landscape architects - that is, Green Infrastructure as their equivalent of Urban Forest. 

What I see, for the most part, is spatial development happening the same old way and trees being removed that could have been protected, preserved and retained for lack of Best Management planning and design during the design phase of public infrastructure projects. It?s one thing to have laws and ordinances, it?s quite another to see that realized before damage is done and trees are removed. We have many strategies to enable a Building WITH Trees approach to ecological design but realizing those strategies and making them required is a whole another ball game.

Please let me know me if my observations are not, for the most part, correct.

In addition, let?s really look at the term Infrastructure as it is applied to trees and the landscapes they populate, aka soil. When we construct a building, we do that with people?s needs in mind in addition to all the regulations and standards. We consider the building infrastructure but do we also consider people infrastructure? They are, according to the dialogue offered, part of the construct but we never assign infrastructure to people as a descriptive. 

Now, if we look at how we might design a sidewalk if we wish to accommodate trees. We might construct root paths or soil trenches or we might install a structural substrate such as CU? soil underneath the sidewalk. This is definitely infrastructure but we are doing that, as with building construction, to accommodate the living organism we are asking to exist in this location. How is that different than the people who will occupy the building that?s been constructed?

Last, yes, trees and other flora are used in bioswales and bio retention constructions but when you study this with Penn State Extension and Philadelphia Water, which I have, only the water retention part of the construct is referred to as Green Infrastructure. The plants and the soil are not, as they are not construction elements in the infrastructure sense but rather functional living elements that enhance the ability of the construct to retain water and facilitate filtration.

In most of Europe, Urban Forestry is not readily available as an area of study in universities and many of the BMPs known in the US and Canada are not known here. Planners, Architects and Landscape Architects are still dictating the HOW we Build WITH Trees but affording our urban trees their preferences is not yet the order of business. Here in Switzerland, there is a continuing education initiative that?s getting under way to remedy that situation and actually create the profession of Urban Forester. The term Green Infrastructure was successfully challenged and it?s control of the dialogue diminished.

Just some food for thought.

Kind regards from Luzern Switzerland
Naomi

While the US EPA?s stormwater definition is dominant in the US, in Europe green  infrastructure is typically considered networks of connected green space that provide multiple ecosystem services and support biodiversity, and increasingly is broadly discussed as a process for strategic landscape planning.  My research on Canada (primarily focused on Ontario)  is that different definitions are used within and between different governments/municipalities, although trees are often front and center.

While cities also benefit from ?natural capital? such as intact watersheds that provide clean water, there?s a lot of ?green infrastructure? being installed and maintained to provide benefits such as storm water management. This includes trees, bioswales and other vegetation. It?s installed and maintained just like other infrastructure.

I suspect your comment might ruffle more than a few feathers in the Canadian urban forestry community, many members of which have been working long and hard for our urban forests to be recognized precisely as such. I would argue that the distinction of whether something is a human physical construct or not is an arbitrary and outmoded way to define infrastructure ? what counts is why and how those assets are managed for the services they provide to communities and the environment.
>  
> While neither your citation nor mine are from Manitoba?the home of Trees Please Winnipeg?it may be of interest to you to note that Ontario Regulation O. Reg. 588/17: Asset Management Planning for Municipal Infrastructure under the Infrastructure for Jobs and Prosperity Act, 2015, S.O. 2015, c. 15 defines a green infrastructure asset as:
>  
> ?an infrastructure asset consisting of natural or human-made elements that provide ecological and hydrological functions and processes and includes natural heritage features and systems, parklands, stormwater management systems, street trees, urban forests, natural channels, permeable surfaces and green roofs.?
>  
> Perhaps Manitoba has similar legislation?that I don?t know. Regardless, the whole objective is to recognize trees and urban forests as the vital community infrastructure assets they are so that they will be managed using some of the same principles and approaches as more ?traditional? human-constructed municipal infrastructure . In fact, the above-cited regulation compels Ontario municipalities to do just that by 2023, and with very good reason.
