Will Silva Cells help improve Toronto's urban forest?:
The city's Official Plan calls for the extension of the city's tree canopy from its current 17% to 30%. One of the major issues limiting the current tree canopy is the difficulty in growing healthy trees along the city's main thoroughfares. Urban trees face several difficulties, but the most intractable issue is the problem of soil compaction. Trees are healthiest when they are planted in uncompacted soil because this allows water, air and nutrients to reach their roots. However, an urban environment requires hard surfaces to support people and vehicles, and hard surfaces naturally compact soil. Silva Cells are a potential solution to this problem.
