We are just about to start to work on open spaces around Waterloo and I thought as a preparation for my site which is a street and will almost certainly involve trees it would be good to try to learn more about what you need to consider when designing with trees.
Trees are the new black
Went to one of the breakfast talks at the NLA. The subject was trees and held by Martin Kelly from Lovejoy and Jim Smith from the Forestry commission. Both are involved in the Trees and Design Action Group TDAG. The main points they emphasized were:
Trees need space and need to be managed right.
The importance of putting an actual value to a tree, to make other professions understand their value
Promoting an understanding of trees
The cost of manging the tree in relation to the value of the tree. A high value tree might cost more to maintain, but there are solutions to avoid and help management issues for the future.
At the moment there are more trees being planted in London than ever before. The problem is that it is not always the right kind of trees and the way and space where they are planted are not right.
Trees are identified as playing a major part in the climate change scenario. Trees can help to decrease the Urban heat island effect. They are also important to health and wellbeing. They provide shade, but you also need to consider where trees are planted in relation to buildings, not to shade too much sun, that is valuable for the building to absorb heat from the sun to heat the buildings. But at the same time you would want the tree to provide shade in the summer to keep the building from getting too hot.

Right Tree Right Location - to ensure future tree planting in London is appropriate, sustainable, considered and permits the long term survival of those trees planted so that they fulfill their growth potential and make the maximum contribution possible without causing many of the problems traditionally associated with planting trees in urban areas.

Trees also absorb CO2 from the atmosphere (but CO2 are also released during deforestation). There is also research supporting trees role in absorbing NO2 from the atmosphere to reduce pollution.
The average value of a tree in London is £8000 - £10 000. The total value of all street trees in London are £2.9 billion. And that is not including the parks. The value of a tree is done by the CAVAT system which can be read more about on the London tree officer website.
For me this has left me with a lot of reading and a better understanding of trees and some of the things that you need to consider when consider planting trees in designs especially in an urban site. I think it will be really important to provide management plans for trees in your designs, so that councils know how to look after the trees and to avoid future problems that the trees could occur. But also trying to sort out existing problems and provide solutions, for example root pruning and extension of existing tree grills. Even though you will probably work with a tree officer on your schemes in the real world I think a good understanding of the basics is very important.
Also promoting new developments to include trees in their schemes and to work with architects to change the building foundations to work with trees.
At another level there is also the opportunities of promoting fruit tree orchards to come to the UK, since a lot have disappeared over past years. I would love to have the opportunity to promote an urban orchard to highlight the issue of the future importance of local food production.
