The line graph shows how the amount of three forest industry products changed over the 1980-2000 period. Overall, figures for all groups changed dramatically, with the timber observing the most alterations. What is more, paper manufacture rates increased consistently over the years, dominating over other categories in the final year.
Focusing on the most inconsistent figures first, timber ranked as the second most produced material in 1980. Initially, the figure jumped from about 5 million tonnes to just 10 million by 1985 before seeing a gradual decline to around 6,5 million tonnes in a 10-year period. Finally, production of timber slightly increased and ended with approximate figures of 7,8 million in 2000.
With regard to paper manufacture, the figures for this industry in the first year exhibited the lowest rates (4 million tonnes), but were able to take precedence over miscellaneous sectors coming to the end. In 20 years the production of paper grew to approximately 8.5 million before undergoing a marginal drop of 5 thousand tonnes by around 1997. However, the figure, then, saw a sharp rise, reaching 12 million tonnes by 2000.
In contrast, pulp production declined dramatically from 6 to 2.5 million by about 1983, bucking the upward trend. However, the figure quickly recovered to 7 million tonnes and remained stable till about 1997 before going up to just shy of 10 million by the final
year.
