Why Plant Trees ?

Economic & Personal Benefits of Trees
- In urban areas "heat islands" can cause temperatures to be three to five degrees Celsius warmer than surrounding areas, trees help cool the environment
- Deciduous trees can reduce air conditioning needs substantially. Planting trees around your home will conserve energy and lower the cost of utility bills. Three well-placed deciduous (leaf-losing) trees on the east, south, and west sides of a home will shade it from summer sun and lower cooling costs by 10 to 50 percent. In addition to saving money, this conservation of energy directly translates to less carbon dioxide produced at the generating plant that serves your house. Trees can also produce savings in cold weather. Staggered rows of evergreen trees on the northwest side of the house (or the side with prevailing winter winds) will block harsh winds and lower heating costs.
- Evergreens can help to lower winter heating costs 10-15%
- Trees help attract tourists and investors
- Trees can increase the value of homes
- Trees assist with the development of other future resources like wood, agricultural productivity, textiles and medicinal products
- Views of trees contribute to positive human mental health and relief from mental fatigue
- Childhood development where trees and green spaces are present is greatly improved; this is seen in improved attention span, concentration and creative play
- Calculate the tree benefits with the Tree Benefit Calculator (presently operates in the United States)
- The i-Tree suite of software tools was developed to help users—regardless of community size or technical capacity—identify and manage the structure, function, and value of urban tree populations. i-Tree allows you to promote effective urban forest management and sound arboricultural practices by providing information for advocacy & planning, baseline data for making informed decisions, and standardization for comparisons with other communities. Better understanding of benefits and services provided by community trees, increases investment in stewardship, operations, and maintenance.
Reduces the Effect of Global Warming and Improves Air Quality
- Reduce the greenhouse effect by absorbing CO2. By absorbing and filtering out nitrogen dioxide (NO2), sulfur dioxide (SO2), ozone (O3), carbon monoxide (CO), and particulate matter less than 10 microns (PM10) through their leaves, trees perform a vital air cleaning service that directly affects the well-being of people and reduces the greenhouse gases that are a contributing factor to Global Warming.
- An acre of trees can remove over two tons of carbon and generates oxygen for 18 people for a day
- 500 full-sized trees to absorb the carbon dioxide produced by a typical car driven 20,000 km/year
Adds to Water Quality and Biodiversity
- In rural areas without tree cover, the sun bakes the earth and contributes to soil erosion.
- Trees and other green spaces hold ground water, protect soil, filter many contaminants and help keep our water and waterways clean
- Trees along stream and rivers, ponds and lakes prevent soil erosion and protect water quality, fisheries resources and property values
- Trees provide natural habitats, food and cover for wildlife, and the nutrients necessary to sustain ecosystems
- Trees promote biodiversity across ecosystems including the Credit River's highly valued cold water fishery
- Planting trees reduces the spread of weeds according to Farm Forest Line.
Plant Native Tree Species
- Native tree species best support local plants and animals which are under constant threat from other invasive species and development
- Native species that are adapted to our region, are pest and drought tolerant and require less watering and maintenance

- EverGreen.ca Native Plant Database
