Throughout our 38 year history in Central Kentucky, sustainability in the urban landscape has been a fundamental and guiding principle for Dave Leonard Tree Specialists. Before sustainability was a catch phrase, we have been spreading the word and putting it into practice in our everyday operations. To us, promoting sustainability in the urban landscape means that we raise awareness of the importance of trees in our communities. It also means that all work is completed using the most up-to-date and sound arboricultural and horticultural practices in order to ensure the healthiest landscapes, while minimizing chemical use and treating pests only as needed and in a targeted manner.
In addition to adopting an important or noteworthy tree in the public space on an annual basis and providing for its care, Dave Leonard Tree Specialists has pledged to plant more trees in our community than we remove. It is true that Lexington has an aging urban forest that is in decline, so we decided that it is more important than ever to commit to this sustainability initiative. Beginning in 2013, we will track all tree removals and tree installations and promise to make up the difference, if any, by planting trees in public space where it is needed.
With the addition of Kentucky’s most complete organic lawn and landscape care services, Dave Leonard Tree Specialists has taken its long-standing dedication to sustainability to a new level.
From Davey Resource Group: The presence of trees and forests is an indicator of the economic and environmental quality of a community. Trees provide significant and measurable benefits to a community such as reducing stormwater flow, improving water quality, and increasing property values. The following are examples of some of the many benefits trees provide to the quality of life in our communities.
Trees help manage stormwater flow by intercepting rainfall and slowing the rate at which it runs over the surface of the land and seeps into the ground. When trees are present, the flow of water is spread over a greater amount of time (time of concentration), and the impact of a storm on the facilities built to handle it at any one time is smaller. -American Forests, www.americanforests.org
Trees act as natural pollution filters by using by-products of urban living that can pollute streams such as nitrogen, phosphorus, and potassium. Their canopies, trunks, roots, and associated soil and other natural elements of the landscape filter polluted particulate matter out of stormwater flow before it enters storm sewers. - American Forests
Research by the USFS shows that in a 1-inch rainstorm over 12 hours, the interception of rain by the canopy of the urban forest in a city reduces surface runoff by about 11.3 million gallons, or 17%. These values would increase as the canopy increases. -American Forests
In laboratory research, visual exposure to settings with trees has produced significant recovery from stress within five minutes, as indicated by changes in blood pressure and muscle tension. – Dr. Roger S. Ulrich, Texas A&M University
Trees can be a stimulus to economic development, attracting new business and tourism. Commercial retail areas are more attractive to shoppers, apartments rent more quickly, tenants stay longer, and space in a wooded setting is more valuable to sell or rent. -The National Arbor Day Foundation, www.arborday.org
Trees properly placed around buildings can reduce air conditioning needs by 30 percent and can save 20 to 50 percent in energy used for heating. -USDA Forest Service, www.fs.fed.us
Healthy, mature trees add an average of 10 percent to a property’s value. -USDA Forest Service
The planting of trees means improved water quality, resulting in less runoff and erosion. This allows more recharging of the groundwater supply. Wooded areas help prevent the transport of sediment and chemicals into streams. -USDA Forest Service
Over a 50-year lifetime, a tree generates $31,250 worth of oxygen, provides $62,000 worth of air pollution control, recycles $37,500 worth of water, and controls $31,250 worth of soil erosion. – USDA Forest Service
