Trees can be of great benefit to building a natural foundation that conserves water, and reduce soil erosion.  If planting trees on your own land, consider planting varieties that root well in a variety of soil conditions, and perhaps those that bear edible fruit.  Properties that are constructed on the sides of steep slope, or high bank, will need to consider planting the proper types of trees that reduce the amount of erosion.  Homes that are located in zones that are prone to natural erosion will need to do the same.

The best trees to consider are those that closely match the natural surrounding area.  Planting trees that are not native to your zone, may inhibit, or even prevent, growth habits that are needed to establish early root development.  Below is a list of trees that do well in conserving water, have reliable root systems, provide either decorative or dense foliage, and help to naturally reduce soil erosion:

Dogwood – Dogwood trees create a beautiful display in the spring, and its roots travel deep into the soil.  Dogwood trees do not have hard wood, but they do very well in a variety of soil conditions with minimal fertilizer.  When planting Dogwood trees, be sure to plant them far away from drain pipes since its’ roots can travel long distances. Pine – Pine needles may need to be raked in the fall, but can provide suitable nesting places for birds and grow tall with deep roots.  Pine trees, like Oak, can live for many years.  If they get too high, or start to encroach upon power lines, they will need to be trimmed. Oak – Oak is a hard wood, and is used for a variety of purposes including making furniture.  It is well suited to all types of weather, and grows well in most hardiness zones across the U.S.  Oak trees will need to be maintained to ensure their height does not pose a risk to overhead lines, and other homes. Magnolia – While this tree is not often used for its softer wood, it maintains a thick trunk, long branches, and large, fragrant flowers that can accentuate a landscape Black willow – Often found along river banks, Black Willow trees are shade tolerant and do well in moist soil conditions.

While there are many other options, the goal is to select a tree that is tolerant to varying weather conditions, and has root systems that are strong, and deep.  In addition to planting for soil conservation purposes, trees can add shade, provide a beautifully decorated lawn, and help retain water in areas where there is too much moisture.  Be creative when selecting which trees to plant.  Always speak to a local greenhouse, or tree service, for tips on tree maintenance, and make sure to research which types of trees grow best in your zone.
