Learning from Spring Wildflowers, and how We Bring Them Back

Every year myself and many others eagerly await the arrival of the ephemeral spring wildflowers. In the past few days I’ve been out scouting for them around Peterborough, and it appears they will be in full bloom soon! In Peterborough it is possible to see these ephemeral forest flowers in Burnham Woods, the Trent Nature areas, the Fleming College Property, and some places in Jackson Park. When visiting these places, be sure to tread carefully and take nothing but photographs.

Being more than just photogenic and beautiful to look at, early spring wildflowers can be an excellent indicator of forest health. These early wildflowers support insects and pollinators of many different varieties. Notably, many of these spring wildflowers are pollinated by various ant species, instead of other flying insects. A good reminder to not forget about ants as an important pollinator in our ecosystems! Beyond pollinators, many larger animals rely on these plants as a source of forage. Many spring flowers produce fruit, and leaves that forest animals will feast upon.

These flower species are often sensitive to environmental changes and human activity, which also makes them an early indicator of a declining forest health. Changes in the water cycle due to nearby construction, trampling of plants by humans, and invasive species can all have an impact on the health of these wildflower and forest communities.

Here in Peterborough’s Jackson park, these spring wildflowers are few and far between. The forest has experienced many of the impacts mentioned above, and trampling of the forest floor has reduced the chances of their revival to a minimum. It does not need to be this way, communities in other parts of the province have created simple and effective ways of managing the human impact on the forest ecology.

In urban forests, often the forest undergrowth becomes trampled by people walking through the forest. The trampling of the undergrowth results in a decline of flowers, and the remaining flowers are often picked by visitors. In London Ontario, along the Thames River the Garden Club of London had an elegant and beautiful solution to this problem. Last year I visited their woodland garden to explore this oasis in the middle of their city. By strategically placing fencing throughout the forest and adding pathways where people frequently passed through the forest, the woodland garden was able to revive the local forest ecology while still providing opportunities for visitors to pass through the forest and marvel at the beautiful flowers.

Urban forests, although not pristine, do not need to be resigned to an eternity of ecological degradation through human use. With some tender care the Garden Club of London shows us how some careful planning can bring back the wildflowers for all of us to enjoy. It is my personal hope that in the coming years we can bring the flowers and pollinators back into Peterborough’s own Jackson Park.

Field Notes: Signs of Spring in Jackson Park

Field notes are brief reports I occasionally publish that describe the local environment. Subscribers to Stewards Notes do not receive and email when field notes are published and they are not listed on the front page. Follow along if you like.

Spring wildflowers are appearing in Jackson Park. Today (April 14th) on our outing we noticed Colt’s Foot, Trout Lilies and Wood Lilies. Additionally we noted an Osprey overlooking the Old Mill Pond near the pagoda bridge. Over the past week we have also noticed a Blue Heron in the pond during the evening hours. Looking forward to more flowers coming in to bloom!

Spring Wildflower Scouting in Jackson Park

This time last year, wildflowers were in full bloom across the Kawarthas. This spring has been rather slow to start the bloom. I wanted to be prepared for the eventual blooms of wildflowers throughout the city, so I started with the closest park. Jackson Park isn’t exactly prime wildflower habitat, I suspect that nearly a century of heavy human use has probably had an impact on their diversity in the area. Nevertheless I was able to find some early signs that Trout Lillies and Marsh Marigolds will be blooming soon in Jackson Park!

The willow is starting to put out buds and the poplars and birches have catkins weighing down their branches. I also noticed that two of the mighty white pines adjacent to the pond are in rough shape, and may in fact be dead… A sad day for sure. Also plenty of signs of woodpeckers in the park. Noticed a beautiful Pilliated Woodpecker high up on a dead tree.

I’m a sucker for little streams and creeks. So beautiful and peaceful.

Jackson Creek Pollution – Final Update

Today I took a stroll up to the Lilly Lake Subdivision to discover what had come of last week’s events. I knew that on Friday there had been activity on site, but I didn’t feel like popping my head into an active construction site, one that my actions may have precipitated. It seems that the construction company has fixed the giant hole in their sediment fencing by adding several more layers. Sections of the fence now are 4 layers thick. In addition, a wall of boulders was constructed at the outlet of a giant erosion scar. It will be interesting to see if even they can hold the water back. (more…)

See How The Lilly Lake Subdivision is Impacting our Waterways

This past week my partner alerted me to the fact that things in Jackson Creek looked a little off. “Like chocolate milk” is how she described it. I’ve seen rivers that looked like chocolate milk before, but never Jackson Creek. I decided to go have a look to see what was causing the phenomenon. First I went down to the creek near the entrance into Jackson Park. Indeed the water was murky with silt and mud.

Murky water like this is bad for fish and other aquatic organisms. It can suffocate fish, decrease light reaching into the water to allow plants to grow and can mean increased nutrients will lead to algae blooms and decreased oxygen concentrations.

After discovering the milky water that had found its way into creek I wanted to see what the water looked like upstream of any housing developments. I drove outside of town to see what the water looked like where the river crosses under Ackinson Road.

Sure enough the water was clear and crisp. Some tannins were in the water that gave the water a “tea like” appearance. This is a natural phenomenon and no immediate cause for concern. It was obvious that there was something along the banks of Jackson Creek that was causing the pollution in the area.

Flowing into a small tributary along the North side of the housing development on Lilly Lake road was one of the most egregious cases of poor sediment control. Along the slopes of the new construction, huge gullies of sediment had been carved out of the embankments and sediment was pouring into a failed stormwater pond to be deposited in Jackson Creek.

I’m not sure what how to fix this situation, city council is consistently unwilling to take action on these issues, Peterborough is home to several failed stormwater ponds. And it seems like the problem is not getting better any time soon. Perhaps a new city council will be willing to make the changes required to ensure the continued health and wellbeing of our waterways, and ultimately our community as a whole.

This Is Why Jackson Creek Matters

This spring so far has not given us much in the way of precipitation, but that’s not to say that we can’t see our surrounding environment hard at work. In Peterborough we have a long history of flooding in our downtown and surrounding neighborhoods. Looking at old maps of Peterborough, it is easy to see why this is the case. When the area was first settled 200 years ago, Jackson Creek meandered through a wetland located where the downtown currently resides. The river still carries memories with it, when the downtown flooded in 2004 the path of the stream passed through buildings and shops in much the same way as it did in times gone by. (more…)
