The Many Benefits Of Trees

Have you ever watched the sun’s rays burst through the trees on a crisp winter morning or lay beneath the comforting branches of a shade tree on a breezy summer afternoon? Have you ever breathed in the scent of the forest after a soaking rain? Have you allowed your senses to be aroused to contentment by simply standing among the trees?

If so, then you are fully aware of some of the numerous and far-reaching benefits that trees provide. Trees play an important part in our lives, not only environmentally, but also psychologically and economically.

The environmental contributions of trees are consequential in our individual lives as well as the municipalities in which we live and in our wildlife communities. Most importantly, trees absorb carbon dioxide from the air and convert it into the oxygen that we breathe. A mature tree provides enough oxygen per day to support four humans; one acre of trees provides enough oxygen for the survival of eighteen adults yearly.

Environmentalists have noted that carbon dioxide levels are increasing, and this leads to warmer temperatures and other changes in our climate. Trees help to mitigate those effects. One mature tree can store forty-eight pounds of carbon annually and an acre of trees can absorb 2.6 tons of carbon each year! That is approximately the amount of carbon emitted by a car that is driven 14,000 miles.

Trees also benefit our environment by reducing the amount of erosion and rainwater run-off. Tree roots keep soil in place and provide space for the ground to absorb rain. Pollutants contained in rainwater are dispersed as they travel through the tree roots prior to flowing into various waterways. Trees also benefit our waterways by providing cover, thus keeping water temperatures cool enough during the summer months to support aquatic life, which in turn keeps the ecology of our waterways healthy. Without trees and other vegetation, rainwater run-off would cause significant flooding, thus increasing costs related to mitigating excess levels of rainwater in our communities.

Trees planted within our municipalities help to keep temperatures cooler during the summer months. Tree-friendly landscapes keep temperatures 3-10 degrees cooler than properties without trees. Trees planted strategically around your home can reduce both heating and cooling costs. Cooling costs may decrease by up to 30% with adequate shade from trees. Heating costs are reduced when planted trees serve as a wind blocker during the winter months. Trees add curb appeal which may increase the value of a property by approximately 15%,

These are just a few of the most important benefits that trees provide to us in various aspects of our lives. Once you as a homeowner have decided to avail yourself of some of the above-mentioned benefits of trees on your property, there are several things to consider. As a first step, it is crucial to pinpoint the desired benefits you hope to gain in planting one or more trees. For example, if the benefit you seek is a large amount of shade covering, a Juniperus virginiana (Eastern Red Cedar) would be a poor choice whereas Acer Rubrum (Red Maple) provides much more shade cover.

Always take into consideration the mature size of a tree as you determine the location for planting. This requires researching your tree choices to discover the anticipated height as well as how widely the root system will develop. Root systems require room to grow to maintain the health of the tree, so planting too near a structure or sidewalk should be avoided.

When selecting a tree, it is also important to determine its soil and light requirements. For example, planting a tree that requires well-drained soil in a continually wet area may cause tree health to deteriorate and eventually the tree may die.

It is also important to learn what time of year is best for planting. Many trees are planted toward the end of the dormant season, in March and April, when temperatures are cooler and rain more prevalent. This allows time for the roots to begin developing prior to the dry months of summer.

If you are looking to plant multiple trees, Pennsylvania has a state nursery offering seedlings in January of each year. For more information, visit the following site:

If we take care of our trees, they will give us many years of enjoyment aesthetically, environmentally and economically.
