Local Enhancement & Appreciation of Forests
LEAF is a non-profit organization dedicated to the protection and enhancement of the urban forest. We offer programs that help you plant, care and give.
Did you know that LEAF uses an assessment tool called Neighbourwoods© to conduct annual tree health assessments on a number of Toronto’s street trees? This year, we conducted assessments on 513 trees, in support of the Adopt-A-Street-Tree program. Learn more about this Toronto-developed assessment tool, and how we use it to advance our stewardship work in the urban forest.
The fall season is here - a time of year where it is very common for homeowners to rake up those colourful autumn leaves after they have fallen. But did you know that leaving fallen leaves in garden beds and around trees, shrubs and other plants over the winter can actually yield many benefits?
Fall marks a time of many magical changes. Trees that were once lush green transform into brilliant shades of yellows, golds, oranges and reds, creating an extraordinary spectacle. But, have you ever wondered why some leaves turn yellow while others lend themselves to bright reds? The mixture of the vibrant fall colours we see is actually a result of complex chemical processes that take place inside the tree as the season changes from summer to winter.
