Maine Amphibian Monitoring Program (MAMP) volunteers collect information about the abundance and distribution of calling amphibians (frogs and toads) on road-side survey routes across the state every spring.
MAMP was established in 1997 and is a joint effort between
Maine Audubon and the Maine Department of Inland Fisheries and Wildlife.
It is also part of a larger national effort, the North
American Amphibian Monitoring Program (NAAMP), which coordinates similar
surveys in more than 25 states.
MAMP was one of the first participants in NAAMP and remains
one of its most successful partners, with over sixty routes across the
state, most of which are run every year by dedicated and enthusiastic
volunteers like you.
MAMP volunteers are assigned a road route with ten survey stops identified
at or near wetlands. The routes are run three times a year, once in
early spring, once in late spring and once in early summer.
Each run is designed to capture a different group of calling amphibians.
The routes are run after dark and take between two and three hours.
At each survey stop, volunteers listen for five minutes and record
the relative abundance and the species of amphibians they hear.

The state has been divided into three zones (coastal, interior, and
northern). Each zone has slightly different guidelines for when to survey
for calling amphibians. There are 61
