| Title: |
Clear-cut Studies
|
| Objective: |
To monitor regeneration of birch trees growing on clear-cut
areas. The data collected provides an excellent demonstration
of the financial and silvicutural capabilities of the management
programs. |
| Year Established: |
1968 |
| Year Completed: |
expected to continue |
| Site Description: |
Original stand was northern hardwood forest between 90 and
200 years-old (old growth). Composition dominated by yellow
birch and beech with >10% paper birch and even less of sugar
maple, red maple, white ash, and hemlock. |
| Statistical Design: |
Compartment 18 and 20 = 1 area of 7.1 acres
These 2 areas were the site for 3 blocks with 4 0.44-acre plots. |
| Likelihood of Locating Study Areas: |
80% |
| Experimental Treatments: |
100% cruise to determine merchantable volume: 1967.
Merchantable wood was logged in compartments 18 & 20
(7.1 acres). Scarification occurred in 5.28 acres of this
area (95% of ground surface was scarified). The study area
was surveyed to establish boundaries for treatments. Applied
4 treatments: 1) control (no treatment), 2) seed only, 3)
light fertilization, 4) heavy fertilization. Fertilizer =
NPK15-10-10 and limestone was dolomitic. Seeding was applied
using a cyclone seeder with a mix of seed and sawdust: 1968.
Herbicide was applied: 1969.
All remaining live trees 1" tall were injected with herbicide:
1989.

pin cherry included height (feet) and (cm), stocking levels
(% birch), and basal area (feet squared per acre): 1970, 1972,
1974, 1980. |
