A Foul Wind in the Willows

The New Zealand Herald is reporting that Waitakere City is considering doing aerial spraying of herbicide to combat invasive willow trees. The targeted invaders are grey willow (Salix cinerea) and crack willow (Salix fragilis) trees growing in areas that are hard to reach on foot. The willows, which can regenerate easily from broken branches or even bark, cause flooding in the area by growing over and blocking drains.
