Green Frog lounging in a vernal pond- photo by Geoff Carpentier Right now is an excellent time to go out and check out these ponds because the frogs, toads and salamanders are out there starting their breeding cycle. These may sound like small things but they can have a huge impact. don’t drain ponds or alter the surrounding watershed.don’t add or remove plant debris from the ponds.Here’s what you can do if you own land that hosts a pond: It may not be long before we simply can’t find salamanders in southern Canada (especially near large built-up areas), nor enjoy the spring frog chorus. Most of our salamanders and many of our frogs can’t survive without them.Īs we continue to develop land, they will become increasingly important and, unfortunately, increasingly rare. One source indicates that the amphibian species developing in ponds generally amount to more vertebrate biomass than the mass of all the birds and mammals in a forest. All these indicators can lead you to these ponds. Look for compressed black leaf litter, greyish soil, watermarks on surrounding tree trunks and moisture-tolerant vegetation. In a way, but they likely won’t have water in them. Often the edges are heavily foliated with small shrubs and flowering plants.
Generally, these ponds are quite small (15 to 20 metres wide and one to 1.5 metres deep). In central Canada, we have been heavily glaciated and forested, so we have many of these places where water can pool. Local geology makes it possible for these to persist, since shallow depressions in the landscape are essential so the water has somewhere to collect. It’s filled with water from rainfall or spring melt that simply collects in a hollow or depression and slowly evaporates until gone. It’s not stream-fed, nor does it rely on a lake’s overflow. It’s a temporary water body that seems to have no beginning or end. Meanwhile, the pond dries up slowly until the fall rains come and it slowly recharges, ready for next year. You might also find a green heron, a snake or raccoon coming to dine on the adult frogs and salamanders that might still be nearby.īy late spring or early summer, hundreds of young frogs and salamanders leave the pond and complete their life cycle in the surrounding forests. Of course all this food attracts predators, so it’s not uncommon to find turtles feasting on the eggs of the various frogs and salamanders. These ponds are magnets for many salamanders, such as the spotted salamander and red-spotted newt, that lay their egg masses along small twigs in the water. Juvenile stages of dragonflies, caddisflies, mosquitoes, backswimmers and diving beetles breed in there as well. Right now we can hear the peeping of the spring peeper that breeds in vernal ponds and small lakes and bogs. Wood frogs sing out their spring songs, sounding like a flock of ducks from its banks, while grey tree frogs, American toads and green frogs lay eggs and live and feed here. Fairy shrimp and other invertebrates abound. Strings of floating amphibian eggs can be seen in its depths. Myriad wildlife use this habitat – frogs, toads, salamanders, insects and other invertebrates teem in vernal pools, depending on where you live in the country.
