The provided line graph illustrates the percentage of land in four nations that was covered by forest between 1600 and 2000. A glance at the figure reveals that all the countries experienced a decline from 1600 to 1850, followed by a growth in the last years of the given time span.
The given data shows that the United States accounted for the highest share of land covered by trees over the whole period. Indeed, it started from roughly 46% in 1600, experiencing a decline to almost 33% until 1990, when a slight increase to 35% can be observed. Additionally, it can be observed that France ranked second in terms of proportion of zones covered by forest, remaining above 10% throughout the time span. However, at the end of time period, it ended closer to the United States, showing a marginal difference between both countries. While America presented 35%, France showed 30%.

On the other hand, Scotland started with 5% in the given period, but ended approximately with 13%. In fact, the positions of both countries switched, and England finished the given period as the lowest nation in terms of land covered by trees.
