The following article was on the BBC News website last week. Its definitely worth repeating. Its clear that Guelph is not the only city dealing with a drastic decrease in its mature tree canopy.

Calls To Green The ‘Concrete Jungle’

Trees can play an essential role in improving the quality of life in UK towns and cities, a report has said.

The Woodland Trust says planting more trees has been shown to improve air quality, reduce ambient temperatures and benefit people’s health.The trend of declining tree cover in many areas needs to be reversed in order to improve access to green spaces in urban areas, the study adds. The trust is also launching a campaign to plant 20 million native trees each year.

“Towns and cities tend to put into sharp relief some of the key problems we are facing as a society,” said lead author Mike Townsend. “So they are a good place to start when try to illustrate just where green spaces can deliver significant improvements for relatively little cost.”

The issues outlined in the report included physical and mental health problems, childhood obesity, air pollution, soaring summer temperatures, flash flooding and diminishing wildlife.

The trust estimated that 80% of the UK population live in urban areas, yet less than 10% of people have access to local woodlands within 500m of their homes.

“If you look back over history, Victorian times saw a real move towards parks and street trees; some of the big street trees that you find in our cities today go back to these times,” explained Woodland Trust conservation policy expert Sian Atkinson.

“What we have seen more recently is that there has been reduction in the number of trees being planted, and there has also been a loss of the lovely Victorian trees with big canopies,” she told BBC News.

“We are starting to miss these from our towns and cities, and not enough thought has been given to replacements and to ensuring that there is going to be enough tree cover in the future.”

‘Slow the flow’
The report also highlighted the role urban trees could play in preventing flash floods.

Ms Atkinson said: “Hard surfaces in towns and cities have increased in recent years, and we are seeing more flooding. One of the problems is surface water drainage. It has been shown that trees and woods are key to help control this sort of flooding. As well as absorbing groundwater, tree canopies help reduce the volume of rainfall hitting the ground and relieve pressure on urban drainage systems.”

She called on civic planners to address the issues highlighted by the report.

“There is quite a lot of talk about green infrastructure,” she observed, “and our message is that we hope that trees and woods are a really big part of that.”

In its Programme for Government report, the coalition government announced that it would initiate a national tree planting campaign.

During a speech in May, Environment Secretary Caroline Spelman said: “If any organism has demonstrated an ability to multi-task, it’s trees. They capture carbon and hold soils together, prevent flooding and help control our climate. They also add immeasurably to the quality of life of our towns and cities.”

She added that in some parts of inner London, it was calculated that each tree was deemed to be worth as much as £78,000 in terms of its benefits.

Ms Atkinson welcomed the government’s announcement: “The UK has very low woodland cover compared with the rest of Europe. We are actually looking for a doubling in native woodland cover. There are some areas that have more cover than others, but – overall – there is quite a big job to do in order to increase tree cover to a level that provides all the benefits outlined in the report.”

To coincide with the publication of the report, the Woodland Trust is also launching a More Trees More Good campaign, which will look to plant 20 million native trees across the UK for the next 50 years.

Guelph’s urban forest canopy sits at 25%, while the desired level is 40%. Guelph citizens have now been waiting for a new stronger protective tree by-law for over 19 years. In the meantime we continue to lose canopy.

Guelph Urban Forest Friends have been advocating for our urban trees, including a strong protective tree bylaw and a separate urban forestry department with a certified forester to more effectively manage tree maintenance and coordinate public education on the value of our mature trees.

Please contact Mayor and Council about this issue. Tell them that our mature urban trees need their help and support. Tell them to get the Strategic Urban Forestry Management Plan completed and a strong and comprehensive protective bylaw passed.
