When Beavers Abandon Their Dam: Heron Pond, South March Highlands

This summer a breach in the dam at Heron Pond in the South March Highland was discovered that appeared to be a natural occurrence. In such cases the beavers will usually repair the dam, but this did not happen and it appears they have abandoned the dam and the pond. This has caused the water levels in Heron Pond to drop dramatically so that what once appeared to be a lake now appears to be drying up.

This has caused concern amongst nature lovers and others who appreciate hiking and biking along the pond, but in reality it might provide an opportunity to observe and study a changing ecosystem if the beavers do not return to the pond and it gradually reverts to forest or pasture or a yet to be determined other natural state.

The following photos were taken before and after the beavers abandoned the pond. The first two in each series were taken from what mountain bikers call The Shield, a flat rocky area on the trail that goes through the Metcalfe Realty lands northeast of the pond. The last three photos in each set were taken from what mountain bikers call Pete's Wicked Trail in the city-owned South March Highlands Conservation Forest southwest of the pond.

What are the odds of Metcalfe Realty v. Beavers to recover damages due to decreased property values from the water going away?
