Abstract
Artificial regeneration has been suggested as one way to increase the oak component of harvested forest in the Central Hardwood Region. Openings in forest stands on the Mark Twain National Forest in southern Missouri were planted to northern red oak seedlings with and without treeshelters. Three years after planting, stem growth, survival, the number of branches, and stem and leaf dry weights were significantly greater for seedlings with treeshelters than for seedlings without them. Root parameters for sheltered seedlings, including root length and total and tap root dry weights, were significantly greater than for unsheltered seedlings. There were no significant differences in diameter growth between treatments. Both temperature and humidity were significantly higher inside shelters than outside. Foliar levels of phosphorus, calcium, manganese, and boron were significantly higher in leaves from sheltered seedlings than in leaves from seedlings without shelters. The use of treeshelters could aid in increasing the oak component of newly regenerated hardwood stands. North. J. Appl. For. 12(1): 36-42.
