Passionate about trees, passionate about our new street trees!


New trees need to overcome the stress of being moved and planted so give them a little help along the way.As long as the tree pit is well dug and free draining it should be possible to water your tree to full health during the hotter period of establishment in the late spring and summer.The tree will put down a lot of root as late as October but whilst the canopy is converting sugars to energy during its growing period it need to take up water to do this.So watering is vital when rain is at a minimum.

City Cooling by Planting Trees

"Adaptation to climate change is essential in-so-far-as the Earth’s climate is already changing and future change is inevitable. The immediate challenge is to decrease the vulnerability of socio-economic sectors and ecosystems to current climate variability. However, it must be recognized that there are physical, technological, financial, behavioral and institutional limits to adaptation.
The challenge now is to negotiate a long-term global equitable regulatory framework with intermediate targets that can limit greenhouse emissions at a level that limits the increase in global mean surface temperature to 2°C above pre-industrial levels. However, the 2°C target is unlikely to be met and the world should be prepared to adapt to a 3-4°C increase".

The role of community groups in managing Manchester's Trees

This statement speaks for itself.
The city council agrees that there would be considerably fewer trees....if it were not for the willingness of the public to get involved.

What The Manchester Tree Strategy means for Whalley Range

It appears that these two issues are not clearly addressed in the current Whalley Range Strategy because in order to deal with the issue of climate change mitigation and adaptation you would need to clearly understand the current role of the present trees and ensure that the tree canopy volume cover is both maintained and increased by a minimum of 10% by canopy volume - not tree numbers.
Therefore tree replacement may need to be in the region of 27 trees or maybe less allowing for small tree canopy growth but certainly more than the 1.5 trees replanted for every 1 removed at the present time>
