As a volunteer, you'll pioneer the work of Earthwatch's Urban Forest Project. In Cambridge, we will be comparing our findings with those of a study done five years ago. The objective of the project is to draw statistical comparisons over time that will allow city officials to relate changes in the urban forest (tree species and size) to changes in environmental conditions (road traffic density, height of surrounding buildings, and surface composition).
