The graph illustrates the generation of three forest-sector products – pulp, timber, and paper – in a European country between 1980 and 2000.
Overall, the production of all three forest industry products rose over the period. Paper output increased steadily and became the highest by the end of the period, while timber showed considerable fluctuations and pulp experienced moderate but consistent growth.
To begin with paper, at the beginning of the period it had the lowest production level, with 4 million tonnes, but during the years it increased steadily until 1995 with about 9 million tonnes. In the next 5 years it increased sharply with some fluctuation to 12 million tonnes, and had the highest production level.
Timber started as the second most produced product, at 5 million tonnes. However, quickly became the most produced product and stayed until 1990, despite an decrease to 8 million tonnes. After this, timber was the lowest production product than other two, finishing the period with just above 7 million tonnes.
Moving to the pulp, it started with a drop from 6 million tonnes in 1980 to 2 million tonnes in 1982. Then the product increased sharply by 7 million tonnes in 1995 and stayed steady and consistent, reaching 10 million tonnes at the end of the period.
