Why should I hire an arborist?

A: Trees restore natural harmony in an urban environment, giving scale to human life. Trees are alive, like us, and require an investment and continuous maintenance in order to provide the maximum desired benefits. Some benefits include:

  • Air Filtration? filters out particulate matter and absorbing harmful gases
  • Purifies Water? slows and filters rain water and protects aquifers & watersheds
  • Cost Reduction? reduces yearly heating and cooling costs by 2.1 billion dollars
  • Climate Control? obtained by moderating the effects of sun, wind, and rain
  • Increase Property Value? well-cared landscape properties are 5-20% more valuable than non-landscaped estates.

For a healthy and long life, trees need the proper maintenance. Therefore, in order to provide proper tree care, you should refer to a certified arborist.

National Tree Benefits Calculator
The Tree Benefit Calculator allows anyone to make a simple estimation of the benefits individual street-side trees provide. This tool is based on i-Tree’s street tree assessment tool called STRATUM. With inputs of location, species and tree size, users will get an understanding of the environmental and economic value trees provide on an annual basis. The Tree Benefit Calculator is intended to be simple and accessible. As such, this tool should be considered a starting point for understanding trees’ value in the community, rather than a scientific accounting of precise values.

"The tree which moves some to tears of joy is in the eyes of others only a green thing that stands in the way. Some see Nature all ridicule and deformity, and some scarce see Nature at all. But to the eyes of the man of imagination, Nature is Imagination itself." - William Blake, "The Letters," 1979
