In the last few years, a team of Vancouver Lower Mainland residents has yanked 74,500 pounds of invasive plants out of area parks, planting in their place 7,100 native trees and shrubs. The cost to taxpayers for all that time and effort? Absolutely nothing. The hugely successful so-called Green Team germinated in 2011 and...
