Around the Refuge

Life in a Vernal Pool

Egg Mass

Vernal pools are seasonal bodies of water that fill as the water table rises with melting snow and spring rains. They are usually isolated and do not have any fish in them. It is expected that in most years’ they will dry up at some point in the summer ensuring that fish cannot survive in them. Fish would predate the eggs of the amphibians that depend on these pools to survive. Wood Frogs and Spotted Salamanders are the residents of these pools that we are mostly concerned with. They have already migrated to the pools on rainy nights earlier in the season and have been breeding for a couple of weeks by now. In addition to the above mentioned species, we will often find Spring Peepers, Green Frogs, Pickerel Frogs, Red-spotted Newts and Spotted Turtles in these pools. We are participating in a long term research project which was initiated by the United States Geological Survey (USGS) called the Amphibian Research and Monitoring Initiative (ARMI) for the Northeast Region. Early spring is when refuge staff conducts surveys. Information on the size, ph, water temperature and vegetation is some of the data that is collected and submitted to the USGS. We also count the number of egg masses for each species that we find. This information is added to a data base along with that of other refuges and parks in this region. We also use this project as a field biology teaching tool for local high school and college students who visit the refuge and help us perform these surveys.
