The line graphs compares the production rates of timber, pulp, and paper in the forest industry of an unspecified European country from 1980 to 2000. Overall, all three products saw an increasing trend, albeit to varying degrees, with paper becoming the dominant product on the chart.
In 1980, 6 million tonnes (mt) of timber were produced in this country – the largest volume in that year. Over the ensuing five years, this figure reached its peak of 9 mt, after which there was a steady decline to around 6.5 mt. From 1995 onward, timber production picked up again, closing at nearly 8 mt.
The volume of pulp production also rose by 2 mt over the study period. It started off lower at 4 mt and, despite a period of slight decline between 1985 and 1990, gradually went up to 6 mt, making it the least produced product in the country’s forest industry.
Paper, though comparable to the previous two products, was something of an outlier. Its production started at a chart low of 3 mt in 1980 and, rising steadily, closed at 10 mt: the largest volume in the study.
