Calculating wood mass for harvesting

The animation shows what a forester does to calculate wood mass. Animacja przedstawia czynności, które wykonuje leśniczy w celu obliczenia masy drewna.
Measuring the diameter at breast height and the height in the tree stand
A forester instructs an intern how to measure the diameter at breast height of standing trees. The forester presents a caliper and informs that the measurement of the diameter at breast height is an element of stock survey, necessary to establish the growing stock. The height is measured with a clinometer and a measuring tape, or by cutting down a few trees and taking direct measurements.
Leśniczy instruuje praktykantkę w jaki sposób dokonuje się pomiaru pierśnicy drzew stojących. Prezentuje tzw. klupę, czyli średnicomierz. Leśniczy zwraca uwagę, że pomiar pierśnicy to element wykonania szacunków brakarskich, niezbędnych do określenia zasobności na hektar. Wysokość mierzy się za pomocą wysokościomierza i taśmy, lub ścinając kilka drzew i dokonuje pomiaru bezpośredniego.
Forester: Today, I will acquaint you with the practical side of taking measurements in tree stands during stock surveystock survey. General information on each tree stand, i.e. height, indexindex, growing stock and many other, is written down in the valuation descriptionvaluation description of the forest. However, when planning the harvestharvestof wood material, we can’t use descriptive data. We need to take measurements of the height of the tree stand and thediameter at breast heightdiameter at breast height, and decide what assortments we will obtain.
Intern: Do we always need to measure all of the trees?
Forester: The traditional measurement of the diameter with a calipercaliper is the most accurate method. We embrace the tree with the calipercaliper at the height of about 130m above ground. The results are written in the field diarydiary. Then, we measure the height for individual thickness classes. We use the clinometerclinometer to measure the height. The measurement consists of measuring about 20 linear meters from the stump and reading the result on the appropriate scale. First, we look at the butt logbutt log and then at the top. The sum of these two measurements gives us the height of the tree. In case of doubts, we can always take the measurements by cutting down the tree and measuring it with a measuring tape along the trunk.
Intern: What mistakes should we avoid?
Forester: Firstly, the measurements of height need to be taken in representative parts of the tree stand, and with a verified true measurement. A 1m error in height can overestimate the mass by about 7% per ha. Secondly, in pine tree stands of the IV and V class, we check whether there is butt log rotrot. If there is, we need to increase the percentage of the stacked assortments at the expense of sawmill wood. And thirdly, in younger age classes we use combined methods. We measure part of the tree stand with a caliper and compare the result with the data obtained by the computer .

Stock survey at a felling site using the single‑tree method
The hypertext material is a dialogue between a forester and a deputy forester. The forester informs the deputy forester that they have to take stock survey in the pine tree stand of age class V, at felling site IB. The deputy forester prepares the field diary, where data will be entered from the recorder. They decide what needs to be done.

Forester: Good morning, miss Barbara.
Deputy forester: Hello, mister forester.
Forester: We are gathering the equipment we need in the officeoffice and then we are going to district 512d. There, we will take stock surveystock survey using the single‑tree methodsingle‑tree method in the tree stand of age class V at felling site IB. You will write down the diameters at breast heightdiameters at breast height in the diarydiary. Then, we will measure the height for individual thickness classes. When providing the diameter at breast height, I will also provide the quality class of the sawmill wood, or the pine plywoodplywood. Maybe you would be tempted to determine the percentage of the stacked assortmentsassortments in the whole mass, with a division into pulpwoodpulpwood S2a and firewoodfirewood S4?
Deputy forester: In my opinion, we should assume 20% of the stacked assortments with a division into 15% of pulpwood and 5% of firewood.
Forester: I agree. That’s a good estimation. Even more so that the division of the stacked assortments was the same in the previous plot.
Deputy forester: The height from the field height measurement practically doesn’t differ from the one stated in the valuation descriptionvaluation description. Maybe we should take the measurement one more time?
Forester: There is no need. However, for the most numerous thickness classes we will cut down some trees and measure the length of the trunks. Ready field materials will be processed in therecorderrecorderusing the stock surveyorstock surveyor program. Then, we will send the data to the National Forest Information System.
Deputy forester: Almost all of the information has already been entered into the recorder. Please, have a look** and check if we can enter the data into the system.

Calculating the surface area of a working plot using the traditional method
The hypertext material is an office instruction. A forester commissions measuring the area of the cut out shelter wood at felling site III B. The forester informs the deputy forester how to measure the surface area.
Hipertekst jest dyspozycją w kancelarii. Leśniczy zleca wykonanie pomiaru powierzchni wyciętych gniazd w rębni III B. Informuje w jaki sposób podleśniczy ma zmierzyć powierzchnię.
Dear miss Barbara,
Please, go to the areaarea in district 136b tomorrow to measure the 4 cut out shelter woodshelter wood at felling sitefelling site IIIb. That way, we will be able to calculate the amount of mesh netmesh net needed for the enclosuresenclosures.
It’s easy with the first shelter wood. The two borders there are drawn by drainage ditchesdrainage ditches of equal length. That will give us a shapely square. Unfortunately, the other two pieces of the shelter wood aren’t regular rectangles. They are more elliptical. As a result, we have to measure the longer and shorter diameter. Then, the data needs to be substituted into a geometrical formula. The last shelter wood is a circle, so we need to measure the radius. Here comes geometry again! Once you are back at the officeoffice, thanks to the obtained data, we will calculate the surface area of the two pieces of shelter wood and their circumference.
Miss Barbara, please, remember that we always need to verify the measurementmeasurementtaken with a GPS. It has happened before that when the sky is cloudy, the obtained resultsresults are inaccurate. Verification is done traditionally: using measuring tapemeasuring tape. Please, take it with you.
See you tomorrow.
