Volunteers identify the species based on their breeding season call or songs<br />
and determine the abundance of each species using a call index of 1 (1-5<br />
individuals), 2 (6-12 individuals) & 3 (unable to count individuals).<br />
In the Tri-County area, anuran species include the Wood Frog, Western<br />
Chorus Frog, Spring Peeper, Northern Leopard Frog, American Toad, Gray<br />
Tree Frog, and Green Frog. Volunteers are unable to observe the other<br />
species shown in Figure 3-6 because they are primarily found along the lake<br />
shore, in the Upper Peninsula, or their population is declining in Michigan.<br />
Volunteers monitored the frogs and toads primarily in Watertown Township<br />
and Meridian Township. Approximately 4 sections within the <strong>Looking</strong> <strong>Glass</strong><br />
<strong>River</strong> <strong>Watershed</strong> were surveyed by 12 volunteers. Tri-County area data from<br />
the frog and toad surveys are available from the MDNR going back to 1996.<br />
