Mesgie: Forest Mapping: What is the metes & bound rectangle system of survey? Baseline and PM principle meridian
What is a Township? A Township has 36 sections, each section is 1 mile square. A section is numbered starting from the right side going left, a section being 640 acres. What is a 1/4 section? = 160 acres = 1/2 mile = 40 chains What is a 1/16 of a section? = 40 acres 1/4 mile is 20 chains, 10 square chains is an acre. a chain equals 66 feet and there are 100 links in 66 feet. When scaling a log that is 32 feet, what is the trim allowance for two logs? A two inch trim allowance would give you a 14' & 16' logs. What is a taper curve? Depicts the height and diameter of the bole of a tree for selected years. What are the four growth curves of a tree? A. The first graph is the growth curve of dbh over age in years. B. Periodic board foot volume. C. The percent of board foot growth over mid-period age, D. Based on diameter growth of breast height, show the relationship between current annual increment and mean annual increment. What is the Dot System used on a timber cruise date sheet? 1 . 2 : 3 :. 4 :: I haven't been doing this stuff for over thirty years so you better wait until a young forester gives you the info. My Forest Mensuration course took me on the road for over two weeks. When we visited saw mills, pulp mills, particleboard plants, plywood plants, stud mills, match stick Companies etc. we had to show a flow chart of the raw product with all the people involved right up to the end product. We also helped the company do quality control work while we experienced the operation. We also learned what is involved in a timber sale. We learned about all the stages of a timber sale which took about five yeas to complete. 1. Stage two print out. In this stage all the timber is examined. The timber is divided into three parts, compartments (3000 - 4000 acres), sub-compartments, then into stands. The stands are examined to determine height, age, dbh, and species. 2. Compartment Prescription Exam, involved the study of wildlife, water, range, recreation, and timber for the next ten years. 3. Environmental analysis report and sale area planning report. The first report gives a description of the area and the impact the cut will have on the area. The second report tells how the cut should be made. 4. Mark and cruise the area. 5. Appraisal, this give them an idea of what to advertise the timber for. 6. Contracts. 7. Sell. Selling is always done by bidding. The forest service feels that the areas that they put up for sale, are areas that need management and through the sale, the land will be improved. We all did a timber cruise of 40 acres and did a logging proposal that was best suited for the area. We also did field trips to many different types of logging operations. Our day would would start at 6:00 am and usually end around 9pm. If one was smart, they would finish most of the assignments which would take you into the early morning hours. A Forest Mensuration report was due after the wood science camp ended.
