1. Total volume of trees in Finland is 2357 milj. m³ with an annual growth 105,5 milj.m³ year 2017. How much did the fellings account for?

86 milj m³

79 milj. m³

68 milj.m³

2. From the forest industry and end product point of view the most important properties of the raw material are the density, knots and possible defects. That's because of (choose 3)

as the density grows the strength properties of wood also improve.

knots have only an effect on visual grades of timber.

knots weaken the strength properties and result in changes during the kilning.

as the density grows the weight grows and so does the logistic expenses too. That reduces the price of sawn timber.

bow and gradient lower the production yield in the sawing.

compression wood may result in splits and shakes.

3. Standing sale is the most common way of trading. It means:

trading the wood delivered to the roadside

the seller contractually gives the buyer the right to fell and transport the sold wood from the forest.

transferring the ownership of standing trees to a forest company

4. The volume is the most important factor affecting the value of the log.

correct

incorrect

5. Knots

causes resin flows.

weaken the strength properties and result in changes during the kilning.

have an effect on visual grades of timber and reduces the value of a product.

6. Sawn logs yield roughly:

1/2 centre cut pieces and 1/2 sideboards

2/3 centre cut pieces and 1/3 sideboards

1/3 centre cut pieces and 2/3 sideboards

7. In whitewood there being less difference in quality properties, the size tends to be the key factor in determining the added value worth.

correct

incorrect

8. Redwood log qualities:
A - sound knotted top log
B - dry knotted middle or bottom log
C - knotless bottom log

correct

incorrect

9. By-products are an important part of any sawmill’s profitability, because about 15% of sawmills’ revenues come from the by-products. The most important by-product economically is

sawdust

chip

bark

10. Value yield is the maximum value that can be obtained from sawn timber. When sawing is optimised on the basis of the value yield, the value produced by by-products, such as chips and sawdust, can be factored in.

correct

incorrect
