The pie chart illustrates how the overall five-year change in volunteer numbers was distributed across five different divisions of the Natural Resource Management Service.
Overall, Forestry accounted for the largest share of the change, while Environmental Education contributed the least. The top three divisions together represented more than three-quarters of the total change in volunteer numbers.
Specifically, Forestry made up 30% of the total change, positioning it as the primary contributor. Water Resources followed closely, being responsible for 25% of the change. Wildlife Conservation also played a significant role, contributing 20%. These three divisions collectively accounted for 75% of the overall five-year change.
In contrast, Parks Management and Environmental Education had much smaller shares. Parks Management accounted for 15% of the change, which was half the contribution of Forestry. The smallest proportion came from Environmental Education, at just 10%.
