Planting Layout

Such goals might include producing income from timber or wood fiber, improving wildlife habitat, or windbreaks/shelterbelts. Remember that many goals are compatible with each other, allowing a single forest planting to serve multiple purposes.

Proper spacing for your trees is critical. Because tree seedlings are small, there is a tendency to plant them too close together. Keep in mind the mature size of the trees you will plant, and space them far enough apart so you can maintain them with your equipment.

Planting Spacing Recommendations

Just like in nature, the spacing between seedlings can vary and don't have to be planted in a grid pattern. Matching the right species to the site and picking the best planting spot will help your seedlings grow into healthy trees.

Windbreaks

You can plant seedlings closer to establish in less time but must plan to remove trees as they grow and fill in windbreak.
Shrubs and small stature trees 2-4 4 ~4,000
Spruce/Fir 4-6 6 1,815
Pines 5-8 8 1,090
Deciduous Trees 6-8 8 900
 

Wildlife Habitat

Usually fewer trees per acre than for timber production and create gaps with no seedlings, mixed species recommended. Find a balance of distances.

Fiber Production

Spruce should be planted in thinned areas with some remaining overstory trees or in open areas such as old fields. Do not plant a monoculture of spruce.

Wildlife Habitat

Mixed plantings of trees and shrubs on a 7 by 8 foot or 8 by 8 foot grid pattern—remember you can allow for variation in spacing. Create gaps of unplanted areas so sun-loving plants that wildlife forage on can grow

Fiber Production

The species you plant will depend on the type of fiber you want to produce. Plant seedlings on a 7 by 8 foot or 8 by 8 foot grid pattern—remember you can allow for variation in spacing.


Windbreaks/Shelterbelts

Plant shrubs and trees perpendicular to prevailing wind directions. Plant conifers that keep their lower branches as they mature if you only have room for one row of trees or shrubs. If you have room for two rows, plant slow growing trees or shorter stature trees on the side the wind is coming from and taller trees on the side where the wind is going. If you have room for three or more rows, plant the tallest trees in the middle row to provide stability to your windbreak.

Spacing of seedlings depends on the species you select and how fast you want your windbreak to develop. Windbreaks will develop faster if trees are planted closer together but requires more maintenance to remove declining trees that didn't receive enough resources to grow strong and healthy.
