The bar graph illustrates the area of forest logged in the Southwest region during the years 1990, 1995, 2000, and 2010, while the accompanying table shows the number of forest-dwelling species—mammals, birds, and amphibians—over three different years: 1998, 2002, and 2008.
Overall, the logged forest area increased steadily over the given period, while the variety of species in the region experienced a significant decline. Notably, the logged area saw a dramatic increase from 1990 to 2010, and simultaneously, all three categories of species recorded notable reductions, with birds facing the steepest decline.
In terms of the forest area, 75,000 acres were logged in 1990, which increased by a third to 100,000 acres by 1995. This upward trend continued, with 150,000 acres logged in 2000, and by 2010, the logged area had tripled compared to 1990, reaching 225,000 acres.
Meanwhile, the number of forest-dwelling species followed a consistent downward pattern. Mammals decreased from 13 in 1998 to 11 in 2002 and dropped further to 7 by 2008. Similarly, the bird species underwent a sharper decline, falling from 27 in 1998 to 15 in 2002, and then to just 11 by 2008. Amphibians also saw a reduction, though more gradual, with their numbers decreasing from 15 in 1998 to 12 in 2002, and further to 9 in 2008. This decline reflects the ongoing impact of forest logging on the region’s biodiversity.

Sample Answer 2
The bar graph provides information on the area of forest logged in the Southwest region over four distinct years: 1990, 1995, 2000, and 2010. Meanwhile, the accompanying table displays the number of forest-dwelling species—mammals, birds, and amphibians—across three selected years: 1998, 2002, and 2008.
At a glance, the bar graph reveals a steady increase in forest logging over the given years, while the table shows a corresponding decline in the variety of species. It is evident that as the logged area expanded, the population of mammals, birds, and amphibians consistently diminished throughout the period.
When it comes to the forest area, 1990 saw 75,000 acres logged, and by 1995, this figure increased by one-third. Logging activity accelerated further by 2000, with the total logged area reaching 150,000 acres. Finally, in 2010, the logged area peaked at 225,000 acres, which was three times the size of the area cleared in 1990.
In terms of the number of forest-dwelling species, the decline was prominent. Mammal species dropped from 13 in 1998 to 7 by 2008, showing a gradual reduction. Similarly, the bird population plummeted dramatically, decreasing from 27 species to just 11 over the same span. Amphibians, though not as severely affected as birds, also saw their numbers dwindle from 15 in 1998 to 9 by 2008, further reflecting the impact of expanding deforestation on biodiversity.

The bar chart depicts the area of forest logged in Southwest region during four specific years—1990, 1995, 2000, and 2010—while the accompanying table provides data on the number of forest-dwelling species, namely mammals, birds, and amphibians, across three years: 1998, 2002, and 2008.
Broadly speaking, the diagrams highlight a significant increase in deforestation activities over the years, with a parallel decline in the populations of forest-dwelling species. The expansion of logging in the region coincided with a marked reduction in the variety of mammals, birds, and amphibians, suggesting that these changes occurred steadily throughout the reported period.
In greater detail, the forest logged initially measured 75,000 acres in 1990, which rose substantially to 100,000 acres by 1995. This upward trend continued into 2000, when the total deforested area reached 150,000 acres. The peak was observed in 2010, with a total of 225,000 acres logged—triple the size of the original area cleared two decades earlier.
Concurrently, the number of forest-dwelling species saw noticeable reductions across all categories. Mammal species declined from 13 in 1998 to 7 in 2008, while bird species fell from 27 to 11 during the same timeframe. Amphibians experienced a similar pattern of decline, decreasing from 15 species to just 9 within a decade. This consistent downward trajectory underscores the negative impact of logging on biodiversity in the Southwest region.
