Catalog #53

Shelterwood Removal and Mowing Study
1) To determine the amount of damage to the understory caused by the removal of a holdover stand.
2) To determine the effect of complete exposure on the survival of various species in the understory.
3) To determine the effect of cutting back the understory in order to produce a seedling sprout stand and to influence stand composition.
4) To serve as a roadside demonstration of shelterwood and the cutting back of advance growth.
1936, 1982
The plots (4 + 5) are located on Compartment 11 in the Kane Experimental Forest. Plot 4 lies 1 chain south of the Seven Mile Road an 1.5 chains west of the road to the Lockheiser special use. Site elevation is 2040' and gradient is uniform of about 1% to the south. Soil is Clymer silt loam which is recognized as being relatively fertile. In 1937, the understory was dense w/ tolerant species and the overstory was considered old growth.
8 square 0.25-acre subplots.
Sawlogs and cordwood were removed from overstory: 1937. Understory on subplots 2 and 4 was mowed to produce an even-canopied stand in which the trees will train each other, and to favor the vigorously sprouting maples and cherries at the expense of the less desirable and weakly sprouting beeches and birches: 1938.
Before treatment, 1937, 1) d.b.h. was measured for all trees > 3.5" in diameter, 2) complete reproduction tallies were made on each of the 4 subplots, 3) photo points were established.
stand table: species: 1957, 1972. 
100% inventory: species, d.b.h., frequency: 1978, 1984.
Data visually checked during computer entry.
Raw data by plot reside on DG and tally sheets are kept with written instructions and detailed maps to each stand. Annually, the raw data are transformed using the REGEN1 program in DG Info. System. Summarized data by plot and by stand reside in a DG-based program that can output to ASCII text files.
