Our Very Own Vernal Pool

If it wasn't for a lecture at one of the Ontario Woodlot Association meetings, I would likely never have found out about the vernal pool. Vernal is commonly used since these pools typically fill up in spring from snow melt and runoff. The pool in this picture is definitely vernal, since by summer time it will be completely dry.

The periodic drying up of the pool is what makes this pool special. It will not support fish and other predators which allows certain woodland creatures to lay eggs etc in relative safety. Next time I am back to this spot I will wear some rubber boots which will allow me to wade in a ways to observe the pool from a closer vantage point. These sneakers were keeping me away and confined to high and dry ground.

It would be interesting to see some salamanders. The only such amphibian I have ever seen was the quite common redbacked salamander up on the mountain in Ile Perrot where I grew up west of Montreal Quebec.
