From his press release:-
“First 1500 of Mayor’s 10,000 street trees are planted across London
Ten boroughs across London are set to become greener and more attractive thanks to the arrival of nearly 1500 new street trees funded by the Mayor of London, Boris Johnson. The Mayor today planted one of the first trees in Islington.
During his election the Mayor pledged efficiency savings would be ploughed into 10,000 street trees to improve Londoners’ quality of life.
The Mayor Boris Johnson said: ‘I have made it a top priority that we make our city a more attractive place to work, live and visit and reversing the decline of street trees is one way for us to do this. I cannot think of a more uplifting way to usher in the spring than the arrival of these brand spanking new trees.
‘This is just the first phase of my programme to make our communities leafier by, during my term of office, planting over 10,000 street trees in areas that have the least.’
The first batch of trees are now being planted in Havering (62 trees), Southwark (122 trees), Tower Hamlets (145 trees), Islington (230 trees), Haringey (250 trees), Merton (47 trees), Brent (100 trees), Redbridge (70 trees), Newham (380 trees) and Hillingdon (51 trees). Londoners say that improvements to their local environment help to make their communities better places to live, and these trees are being planted specifically in areas that will most benefit by boroughs, community groups or charities who applied for funds from the Mayor’s tree programme.”
From a US environmental website:
Benefits of Trees:
Help to settle out, trap and hold particle pollutants (dust, ash, pollen and smoke) that can damage human lungs.
Absorb CO2 and other dangerous gasses and, in turn, replenish the atmosphere with oxygen.
Produce enough oxygen on each acre for 18 people every day.
Absorb enough CO2 on each acre, over a year’s time, to equal the amount you produce when you drive your car 26,000 miles. Trees remove gaseous pollutants by absorbing them through the pores in the leaf surface. Particulates are trapped and filtered by leaves, stems and twigs, and washed to the ground by rainfall”
But air pollution damages them:-
“Air pollutants injure trees by damaging their foliage and impairing the process of photosynthesis (food making). They also weaken trees making them more susceptible to other health problems such as insects and diseases.
The loss of trees in our urban areas not only intensifies the urban “heat-island” effect from loss of shade and evaporation, but we lose a principal absorber of carbon dioxide and trapper of other air pollutants as well.”
Let’s hope that the ones he puts up don’t all die with all the London pollution
and that suitable tough street trees are put up, such as the London Plane tree.
If I see any, I will let you know. A glimmer of progress.
