Abstract or Description
Vernal pools are important pools of water that are only filled during spring and fall months. During the summer months they are typically dry. They are important habitats for many amphibians, reptiles, and insects. This map depicts the significant vernal pool locations in Maine and drought conditions in the month of September 2016 and the amount/location of vernal pools that fell in drought areas. The map was made by overlaying national drought data for the 6, 13, 20, and 27th of September 2016. The data was clipped to the state of Maine and the vernal pools were added along with a halo to enhance visibility. Projection: Transverse Mercator. Coordinate system: NAD 1983 UTM zone 19.
