Tree & Shrub Survival in Shelterbelt Renovation at the Dickinson Research Extension Center Fall 1997

(This project was a three-credit Directed Study for Environmental Biology, under the supervision of Dr. Dan Noble, Associate Professor of Biology at Dickinson State University and Mr. Jerry Larson, Stark/Billings County Extension Agent, NDSU Extension Service)

The data presented in this report is survival of the various coniferous and deciduous trees observed. Average height of the various trees is given in the Data Charts section (height data includes the height of replants).

The shrubs, American Cranberry, Juneberry and Nannyberry, were an understory planting between a row of Ponderosa Pine and various mature deciduous tree species. One-half of the row of shrubs were prepared by tillage while the second one-half of shrubs were planted directly into kill down smooth bromegrass or into a no-till situation. The shrubs were planted in alternating pairs: 2 American Cranberrybush plants, 2 Juneberry plants and 2 Nannyberry (Viburnum) plants. Tables 1, 2 and 3.

The survival of shrubs planted in the non-tilled pretreatment site were Juneberry and Nannyberry at 100% and American Cranberry at 95%.

Overall performance of the three species were American Cranberry at 96.9%, Juneberry at 97.6% and Nannyberry at 97.5%. The three species of shrubs were slightly better in the tilled pretreatment (98.3%) than the non-tilled (95.7%). However, replants may have confounded these results.

In Tables 4, 5, and 6, we report survival of Ponderosa Pine, Scotch Pine, Colorado Blue Spruce, and Black Hills Spruce in two different planting pretreatment sites in an open plot with no shade. All trees were planted in two different pretreated situations: one row mulched and one row non-mulched for each species.

The survival of trees in the mulched pretreatment was slightly higher than those in the non-mulched area. The survival in mulched pretreatment site was Ponderosa Pine, Colorado Blue Spruce, and Black Hills Spruce at 100%, followed by Scotch Pine at 97.6%. The survival in non-mulched pretreatment site was Ponderosa Pine at 97.6%, Black Hills Spruce and Colorado Blue Spruce at 97.5%, and Scotch Pine at 97.3%.

It appears the mulched pretreatment is more successful, but it is difficult to say because we were unaware of the number of replants.

In Table 7, we determined the survival of Ponderosa Pine, Colorado Blue Spruce and Siberian Larch in an open plot with no shade, planted in a weed barrier fabric. Of the three, Colorado Blue Spruce had the better survival with 100% followed by Siberian Larch at 93.%% and Ponderosa Pine with 66.7%.

In Table 8, we determined survival of Rocky Mountain Juniper and Eastern Red Cedar in a tree shelter area with a weed barrier. Eastern Red Cedar had a survival rate of 100% compared to Rocky Mountain Juniper at 95.5%.

We took measurements on the Black Walnut and Ohio Buckeye, but we were unable to distinguish species due to the time of year. For that reason, we omitted the data.
