The given line graph depicts the production of three forest industry products in a European country, namely timber, pulp, and paper over the two-decade period, starting from 1980.
Overall, while the production levels of all three categories experienced notable fluctuations, each showed a substantial overall increase by the end of the period.
In 1980, pulp initially had the highest production, at approximately 5.5 million tonnes, but this figure dropped sharply to just above 2 million tonnes, after which it was overtaken by timber. Between 1982 and 1985, the production of both timber and pulp followed similar upward trends, rising markedly from 6.5 to 10 and 2.2 to 6.5 million tonnes, respectively. From 1985 to 1990, pulp production continued to rise at a slower pace, whereas timber dipped to 8.0 million tonnes in 1987 and remained at that level until 1990. Meanwhile, paper production consistently increased from 4.0 to 6.5 million tonnes during this time.
From 1990 to 2000, timber production declined to about 6.2 million tonnes, rebounded to 8.0 in 1997, and slightly decreased to 7.8 by 2000, finishing as the lowest among the three. In contrast, despite a minor decline in 1997, paper production almost doubled compared to its 1990 figure and became the most produced item in 2000. Pulp also rose steadily throughout the second half of the period, reaching nearly 10 million tonnes by the end.
