Roots are claws that hold the earth in place

Waterside tree planting is important both to the local waterways and the people who live adjacent to them. Tree roots hold onto soil, preventing unnatural amounts of sand and dirt from entering the water systems, which can have a negative impact downstream and damage aquatic ecosystems. Trees provide organic material and habitats for animals, and their shade acts as a temperature monitor for aquatic wildlife.

Trees and other natural vegetation create a buffer between land use and natural habitats. They also benefit us by reducing the impact of flooding, a trend which is becoming more commonplace due to the pressures of climate change.

Riparian buffer zones
The figure above shows a cross-section of a stream and the adjacent riparian area. The sketch shows four zones and the vegetation associated with each. Moving from the water to the upland, the first zone is the aquatic zone and is populated with aquatic plants such as sedges and reeds. The next zone, Zone 1, is an undisturbed forest. Zone 2 is a managed forest of shrubs and trees and Zone 3 is a mix of grasses that help control runoff from neighbouring fields. (Image courtesy Agriculture and Agri-Food Canada)
