Seeing Beyond the Obvious
Nature’s beauty often catches our eye in the towering canopy of a forest or a grassland filled with colourful wildflowers. These habitats provide us with the life-sustaining ecosystem services we all depend on. From soaking up stormwater to filtering our drinking water, to cleaning the air we breathe, nature provides us with important benefits. Yet, there are many unassuming and overlooked habitats that also support a healthy watershed. Here are five habitats that deserve a closer look.
1. Old Fields
Old farm fields or clear spaces feel forgotten but they are undergoing ecological renewal. These grassy expanses, dotted with goldenrod, milkweed and wildflowers, provide nesting areas for grassland birds like eastern meadowlarks and bobolinks while offering a vital food source for pollinators.
Our restoration teams often use old fields as stepping-stone habitat and with restoration efforts, they can be further transformed into thriving habitats, helping to reconnect fragmented landscapes and support biodiversity across the watershed.
2. Vernal Pools
At first glance, a shallow puddle in the woods might seem insignificant but vernal pools are among the most important seasonal habitats in the watershed.
The word vernal comes from the Latin term vernalis, meaning ‘of the spring.’ In English, we use it to describe things associated with springtime. Vernal pools are small, temporary ponds that form in spring from rain and snowmelt, then dry up by late summer.
Because fish can’t survive in these seasonal pools, they provide safe nurseries for amphibians like wood frogs and spotted salamanders to breed and grow. We monitor vernal pools as part of our long-term amphibian surveys, tracking how species respond to changes in climate and land use.
3. Riparian Zones
If you’ve ever walked beside a creek or river, you’ve been in a riparian zone. It’s the lush, green strip of vegetation that hugs the shoreline. These zone provide more than beauty to the landscape. Riparian zones stabilize stream banks, filter pollutants and provide the shade that keeps water cool.
While the best practice is a 30 metre buffer, even a few metres of native shrubs and trees can make a big difference to reducing erosion and boosting biodiversity.
4. Shrub Thickets
Shrublands are often overlooked because they don’t fit our picture of a tidy landscape. Dense and brushy, these thickets offer perfect nesting spots for songbirds like gray catbirds and yellow warblers, and provide essential winter cover for rabbits, deer and other small wildlife.
Many shrub thickets grow naturally in old fields once farming stops. In some places, thickets also form in wet areas where it’s too damp for trees. Both types create important early habitats that are becoming rare in southern Ontario due to urban development, natural succession into forest and the loss of open fields across the landscape.
5. Groundwater Seeps
Hidden beneath your feet, groundwater seeps are small spots where cool water emerges from the ground. This creates moist areas that support mosses, ferns and cold-water streams. In winter, they become vital places for wildlife to drink and find food in snow-free patches. Many are protected as Significant Wildlife Habitat because of their importance.
Our real-time monitoring network tracks groundwater flow to better understand how these seeps respond to changing weather patterns and climate impacts.
Take a Closer Look on Your Next Hike
Every natural space of the Credit River Watershed has a role to play. Protecting and restoring these hidden habitats means protecting our biodiversity and the foundation of a resilient watershed. The next time you’re out on the trail, take a moment to look closer. You might be surprised by what’s quietly thriving at your feet.
