Pruning trees can be dangerous work. If pruning involves working on large trees the knowledge and use of specialized equipment is very important, not only for the safety of the person(s) pruning the tree but also for the surrounding property where the tree stands; homes, businesses, automobiles, on lookers and passers by can be put at serious and unnecessary risks'. Other considerations need to be taken as well when working on trees that are next-to or near-by electrical power lines or have electrical lines running through their branches.
A professional arborist can provide the services of a trained crew, all the required safety equipment, liability insurance and of course the knowledge and experience that can only come with the job |

A single tree will absorb one ton of carbon dioxide over its lifetime. Trees alter the environment in which we live by moderating climates, improving air quality, conserving water and harboring wildlife. Climate control is obtained by moderating the effects of the sun, wind and rain. Radiant energy from the sun is absorbed or deflected by leaves on deciduous trees in the summer and is only filtered by branches of deciduous trees in winter. We are cooler when we stand in the shade of trees and are not exposed to direct sunlight. In winter, we value the suns’ radiant energy.
Air quality can be improved through the use of trees and shrubs. Leaves filter the air we breathe by removing dust and other particles. Leaves absorb carbon dioxide from the air to form carbohydrates that are used in the plants structure and function. In this process, leaves also absorb other air pollutants- such as ozone, carbon monoxide and sulfur dioxide – and give off oxygen.
So plant a tree, take care of the ones you have and help keep our earth GREEN  |
