The face of nature in our city has changed over the past 50 years, just as our streets and buildings have. But few changes in nature are as bizarre as the Britannia pine forest that crossed a lake.
Ottawa naturalist Dan Brunton has been visiting the forest around Mud Lake since the mid-1960s. It is an ecological hot spot, whose combination of different soils, along with the Ottawa River and the small, warm lake, sustain some 640 types of plants and more than 100 birds.
Brunton recently compared photos taken in 1968 to the forest today. What he found was a striking change that almost no one had noticed.
