then we need to apply Whole of Life costing to them as we do with any other asset.
When we do a business case for a new truck we don't just look at the purchase price. We include depreciation, servicing and running costs over the life of the truck because that's what it will really cost us to own it.
Applying the same thinking to tree planting, we shouldn't be just looking at the cost of planting and watering the trees but also the cost of replacing the ones we lose. Because that's what it's really costing us to establish our urban forest.
It's all pretty obvious really.
Which makes it all the more surprising we're not doing it*.
