Hey Peterborough! Hey Jackson Park! Congratulations! We did it! On December 6th 2021 city council voted to add Jackson Park to the official heritage register under the Ontario Heritage Act. For over 100 years Jackson Park has been a fixture in the Peterborough community. Envisioned by the Nichols Trust as a respite from the growing city; this beloved park has more than fulfilled it’s role.
Tomorrow we’ll get back to work, but let’s celebrate this beloved park. By the numbers, Jackson Park is an impressive place. A summary to date (December 2021):
143 Bird Species have been catalogued on the Jackson Park Ebird hotspot
All of these things add such great value to Peterborough, and it is all worth protecting for the future. There is lots of hard work to be done to further protect and restore this important heritage location. From invasive species, trampling of the undergrowth, to climate change, or even just trails in disrepair there is still lots to do. I’m personally looking forward to tackling these challenges to pass this space along to future generations.
Thanks so much to councilor Kim Zippel to bringing this motion forward from the Heritage Committee. And thank you to council for seeing this motion through to completion.
Monday December 6th 2021 will hopefully be a momentous occasion for Jackson Park. Peterborough City council will sit down to vote on a heritage designation for Jackson Park. The implications of this are huge for one of the most cherished locations in Peterborough. In September 2019 the City’s Architectural Conservation Authority Committee recommended that Jackson Park receive this illustrious designation and hopefully this will come to fruition on Monday.
It should come as no surprise to anyone that Jackson Park more than deserves this designation. The park has been a fixture in the Peterborough ever since it was donated to the city by the Nichols Trust 1893. It features prominently in the shared memory of the city. One is hard pressed to flip through any historical account of Peterborough without stumbling upon several references to the venerated park.
Indeed there are many parks on the continent that have received special protections that Jackson Park does not have. Parks built and designed in the same period by Frederick Olmsted generally receive substantial heritage recognition and protections. Meanwhile, Jackson Park has yet to receive protections (or attention) afforded to significantly younger designs and buildings in the city of Peterborough.
One hopes that this can be a first step towards protecting and enhancing Jackson Park for future generations. There are many threats facing the park, and hopefully this designation can assist in pushing the envelope for greater attention to those threats. If you haven’t already, take a moment to go sign the petition being passed to city council. Or write to your councilor to voice your support for this designation.
If you’re paddling through the Kawartha Highlands or taking a jaunt through Peterborough’s Jackson Park, you may have the chance to bear witness to one of the coolest (spookiest?) adaptations of the plant kingdom, carnivory! I’m sure many of you are aware of the infamous Venus Fly Trap, but perhaps you may not be aware of some of the carnivorous plants that may live in your own backyard. Here in the Kawarthas we are host to several groups of carnivorous plants, all of which have their own unique “hunting” strategies. Generally, carnivorous plants are found in areas that have poor nutrient availability.
Because of their unique adaptation, they are able to gather nutrients from insects (or even salamanders!) and out-compete nearby species that rely on nutrients available in the soil or water. When more nutrients are abundant and available for plants to use, carnivorous plants find themselves quickly out-competed by other vegetation. Therefore, these plants have very specific habitat requirements. Bogs, alvars, and groundwater driven ecosystems are all prime areas in which to find these elusive plants.
Unfortunately, human activities can force these beautiful carnivores out of their habitats. Many human activities mobilize nutrients within the soil or atmosphere allowing other species to out-compete them in their habitat eventually leading to their demise. Agriculture can lead to an increase in nutrients through animal excrement making its way into waterways, fertilizers spreading off farms through rainwater runoff and carried by the wind, or nutrients deep in the soil brought up to the surface through tilling. Urban developments can also lead to an increase in available nutrients, through maintaining landscaping, increased soil erosion, or rainwater runoff carrying sediment.
Surprisingly, it is still possible in some secluded places to find carnivorous plants south of the Kawartha Lakes, in an area dominated by agriculture and urban development. So let’s meet these interesting plants, and learn where might you find them.
In the Kawarthas there are two species of Pitcher Plants that are commonly found. These were my introduction to native plant carnivory for a good reason; they are stunning! Often found in the nutrient poor lakes and bogs of the Canadian Shield, you can often see them peeking out from clumps of moss to show insects the entrance to their watery grave. Fine hairs point downward into the pitcher forcing insects towards a small pool of water filled with digestive enzymes. Once a bug is trapped at the bottom of the pitcher, they are gradually digested and used by the plant for the nutrients that they carry.
South of the Kawartha Lakes, it is possible to find these plants in secluded wetlands that have been mostly spared from human activity. I personally have a hunch that there are pitcher plants hidden somewhere in Harper Park. If you happen find some in there, let me know and there may be a (little) prize for you!
I’ll admit, I often forget about Bladderworts when it comes to local carnivores. Their unassuming little yellow flowers don’t invite much suspicion, until you realize that they’re a plant with no (apparent) leaves! Floating across lakes and ponds, most of this plant’s biomass is beneath the surface. If you look at the plant below the water surface you will see little round clumps that are capable of trapping passers by. Initially, these “bladders” are deflated sacks with tiny hairs that act as triggers. When an unassuming daphnia or other tiny aquatic critter touch one of the hairs the bladder quickly inflates, sucking in the creature to be digested. There are several species of Bladderwort in the Kawarthas and some can be spotted nearby Peterborough, Lindsay, Orillia, or other towns in the Land Between.
Sundews are unassuming little plants, with such a pleasant sounding name. However if you’re an insect tempted by the dew looking nectar on the tips of it’s hairs, you might be in for a sticky surprise! Once insects land on the leaves and are trapped, the sundew secretes enzymes to slowly digest it’s prey. Somehow this plant knows the difference between a tasty treat, and inedible material, as it will not secrete enzymes to digest items such as dirt, or tree bark.
These little plants can often be found clinging on to floating woody debris in wetlands, or among the mosses and lichens commonly found in bogs. There are a few sightings of sundews south of the Kawartha Lakes, but they are much less commonly than in places such as the Kawartha Highlands.
I hope you enjoyed this spooky insight into some of our local carnivores. Happy Halloween!
On August 15th 2021 it was 23.9°C at the Peterborough Municipal Airport. By all respects, an average summer temperature. If you looked at a thermometer outside your house though, it might paint a much different picture. In the downtown core and areas along Lansdowne St. temperatures reached as high as 40°C. This represents over 15°C temperature difference! What is happening and how can it be stopped?
The urban heat island is a phenomenon we’ve long known about. It occurs when natural land cover such as forest or meadows are replaced with surfaces that retain heat such as asphalt, concrete or pavement. These surfaces then radiate the heat back out into the local environment, warming the surrounding area. The effect can increase the cost of heating, and put elderly or other vulnerable citizens at risk of heat stroke, and even death.
The urban heat island effect often puts the most vulnerable populations at risk. Some of Peterborough’s lowest income census areas have the highest recorded temperatures. You’ll notice on the map that areas directly south and north of the downtown which are characteristic as lower income neighborhoods, have some of the highest recorded temperatures, while some of Peterborough’s more affluent neighborhoods have much lower recorded temperatures.
Image #1 characterizes a neighborhood south of downtown. Census Canada considers between 35% and 43% of the population to be low income. This neighborhood is one of the hottest in Peterborough, coming in at a 15°C temperature deviation. Meanwhile Monaghan Ward represented in image #2 only recorded a 5°C temperature deviation. It is clear that land cover and tree canopy have a huge impact on temperature deviation. With the additional pressure of climate change, these deviations are likely to become more pronounced over time.
What can be done about urban heat though? Luckily we have some solutions! Planting trees is once again, a major winner in this regard. Not only does tree planting decrease average temperatures, it can lower heating and cooling bills year round for residents, overall a huge win for the climate. Removing asphalt and other “high heat” surfaces can also benefit neighborhoods, replacing asphalt with grass is even a viable solution for combating urban heat. Depave projects around the country have made major inroads in this regard, and perhaps focusing on lower income neighborhoods could have an additional impact.
In all, reducing the urban heat island effect gives us one more incentive to restore ecosystems, plant trees, and protect our natural areas. Perhaps years from now, when you look at the thermometer outside your house, it may more accurately reflect the temperature across our city.
Back in 2014 I had just graduated from my environmental science degree and was eager to start a career in the environmental sector. I had more ideas than time back then, which is obvious from the notes that I was keeping. Fast forward to 2020, I had just completed my masters in sustainability studies, am looking for work, and there is a province wide lockdown. Despite languishing for most of the year, I figured with the time that the lockdown afforded me, I could try to create something epic. I dusted off my old notebooks, and decided this project was worth my time.
It has become increasingly clear that conservation is no longer enough when it comes to our current biodiversity crisis. We need active environmental restoration to solve the problems we are facing as a society. I wanted to create a tool that could scale to produce results for huge environmental restoration projects and be accessible for people and organizations for a reasonable cost.
For the past 4 months I’ve put in hundreds of hours to produce the Aspen. Its a fully autonomous drone capable of quickly broadcasting seed across large areas. The broadcasting wheel is interchangeable allowing users to spread up to 2.5kg of various seed types including treated tree seed, tallgrass, wildflower, clover and anything else you can imagine! (Edit: The Hopper in the video is a small one for testing) The drone is controlled by a base station that uploads a flight plan to the drone. Once the drone is ready, it takes off and completes the flight plan fully autonomously, spreading seed as it goes. The base station is capable of controlling multiple drones simultaneously, opening up possibilities for multiple drones to work in tandem to cover a huge area for restoration projects.
Broadcasting seed is never going to replace planting trees directly, but there are several methods for treating seed to increase their success rate that I have been researching. The University of Alberta has created an interesting seed coating that seems to increase the success rate of tree seeds to as high as 70%. This is definitely something that I would like to experiment with, as it may also assist with even broadcasting of the seed.
There’s still testing to carry out, and some refining to complete the design, but it is a working prototype ready to be put to the test. Please watch the video and let me know what you think! If you or your organization would like to work together to test the drone out on your project or a portion of your project, please let me know and I’m sure we can come up with an arrangement!
Also, if you or your organization are looking for a talented employee capable of making huge projects like this a reality, please reach out and lets have a conversation!
Bonus FAQ: I don’t understand, but several people have all asked “how high does it go?” Lets just say, I’m not going to test it out, but in theory it could ascend at 2m/s for 20 minutes. That works out to about 2.4km in altitude. At that point it would crash to the ground, probably never to be seen again.
In 2020 the coronavirus devastated economies, put millions of people out of work, all at a time of global climate and ecological crisis. 2020 was also the year we entered into the UN’s Decade on Restoration that aims to “prevent, halt and reverse the degradation of ecosystems worldwide”. No matter where you sit on the political spectrum, you can agree that one way or another, we are in a time of crisis. A term that has been tossed around over the past year as a way out of the crisis is “a nature based recovery”.
Nature based recoveries are not a new idea, we can look to the past for models on what it might look like, putting millions of people to work while restoring our natural environments. One of the most ambitious conservation projects of all time was the Civilian Conservation Corps. Over the course of the program it employed nearly 3 million Americans while planting over 3,000,000,000 (Billion!) trees. A version of this program has been resurrected by the incoming Biden administration and is expected to present a plan within the next several months. It will be exciting to see it take shape over the coming years.
Closer to home, we can look to similar projects that helped employ masses of Canadians while enhancing our natural environment. Following the Guelph Conference and the subsequent establishment of the Ganaraska Region Conservation Authority there was a resolution to seek any practical project that would employ civilians in the post war era. The Ganaraska region had become a dustbowl due to the high rates of erosion caused by rampant deforestation and the underlying sandy soils easily being swept away by wind or rain. Restoring the Ganaraska Watershed seemed like an obvious candidate for the project. Over the next several years the Ganaraska Authority reforested over 10,000 acres of land while employing thousands of unemployed Canadians.
The benefits of these programs have extended far into the future. Today the Ganaraska watershed is a popular outdoor tourism destination, and is no longer subject to the destructive flooding it once was. Indeed, a University of Oregon study found that for every million dollars invested in watershed restoration it resulted in 16 new or sustained jobs and up to 2.5 million dollars in total economic activitiy. There are very few public sector investments that have rates of return that scale in a similar fashion.
Locally, what might a project of this scale look like that could employ many people while creating enormous ecological benefit? One such project that comes to mind is the Kawarthas Naturally Connected. The KNC is a natural heritage system plan developed over the past decade that aims to provide a linked network of conservation corridors across the Kawarthas. Perhaps a project that restores a ecological corridor from the Oak Ridges Moraine or Rice Lake in the south to the Kawartha Lakes in the north could be a great starting point? As an added benefit, perhaps a multi-day hiking trail could follow the corridor similar to the way the Ontario Waterfront Trail is used as a platform for restoring coastal ecosystems along the great lakes shoreline.
History has demonstrated that these environmental projects can have an enormous environmental and social benefit, hopefully our recovery can help lead to a sustainable future for everyone. The Kawarthas is a leader in environmental expertise and stewardship, if anyone can accomplish a nature based recovery, it is us! In 2016, the UN designated Peterborough a Regional Centre of Expertise for sustainability, lets put that designation to use and carry out a decade of restoration.
Over the past several years I’ve been asked by several people, “how much of Peterborough is protected?” Its not a straightforward question to answer; between overlapping jurisdictions, policies and laws and the ways in which they are enforced the area of protection in the city limits changes. Recently Debbie Jenkins reached out to me with a proposal to produce a map that attempted to finally answer the question “How much of Peterborough is Protected?“
I first needed to decide what I would consider as a “protected area” in Peterborough. There are several regulations that do not necessarily act as protections for ecological purposes, but have ecological implications. Meanwhile regulations such as the 120m setback for wetlands are technically required by legislation, but rarely adhered to. I decided to take a qualitative two tier approach to my assessment.
Tier 2 protections were generally identified as areas that have some degree of protection, yet are generally ignored, circumvented, or have limited significance. Examples:
120m setback from Provincially Significant Wetlands although technically required by provinical legislation, are rarely enforced on new building developments.
Alterations to Shorelines and Watercourses Regulations technically prohibits construction within the regulated areas adjacent to wetlands and watercourses, although the conservation authority is generally willing and able to provide exceptions to this rule.
Tier 1 protections were identified as areas with significant hurdles to development, and in my experience are generally spared within development applications. Exceptions to these rules are rarely granted (not never granted). Examples:
Within 30m from Provinically Significant Wetlands I can only think of limited examples in the past decade where this limit has not been enforced.
Parks Canada Land this land is federally protected and I consider unlikely to be developed.
City Parks generally city parks are not developed within the city of Peterborough, in large part due to public outcry and what I consider to be “cultural” protections.
This map is far from perfect and includes several approximations, however it should paint an accurate picture of “protected areas” within the city of Peterborough. It will be interesting to see when the official plan is released how this map might change. Advocating for nature has been a huge part of how many of the protected areas in our city have gained and maintained their status, and I hope this map paints an excellent picture of how that work has pieced together.
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.
Hello Bioblitzers! Hope you are all keeping healthy and well these days. We’re quite lucky that here in Peterborough that our parks and greenspaces have remained open to the public. When I’ve been out and about in our local parks, I’ve been pleased to see nearly everyone respecting social distancing protocols. Hopefully the Self-Isolation Bioblitz we held on March 28th helped keep everyone’s spirits high, and perhaps inspired some of you to participate an citizen science in other ways. Over the past week Jenn Baici produced some excellent charts to share with you as a summary of the bioblitz results!
Scouterderyck ended the bioblitz with the most species sighted (45) and the most total observations (64). The most common species sighted was the American Robin (27), Eastern Grey Squirrel (17), and Black Capped Chickadee (17). I was personally quite excited to see that there were even sightings of fish that were included during the event! By my best guess, well over 100 people participated. Thanks everyone for making this even a huge success! Explore the summary charts below or head on over to the project page to check out the raw data!

I’m going to let you in on a little secret… I didn’t grow up a naturalist. In fact, I wouldn’t have ever dreamed about calling myself a naturalist until my mid-twenties. My main priorities as a teen were to be a top 50 competitive Age of Empires II player and to become a chef. I was successful in both of those pursuits; before retiring.
I’d always enjoyed nature, but I’d have been hard pressed to identify more than 10 bird species. But herein lies my secret, since I started on this journey relatively recently I still remember learning to observe. I’m no master naturalist (In fact I’m probably more of a geographer), but I thought I’d share some tips for how to find as many things as possible in your backyard!
This weekend Peterborough will be having its first ever backyard bioblitz. But some of you may be thinking “nothing lives in my backyard” and that my friends is where you are wrong! Some backyards are more diverse than others, but no doubt, there is life out there waiting to be discovered! I’ll share a few pointers to get you started, but remember to use all your senses, intuitions and you’ll have success!
1. Don’t Dismiss Anything
When you’re making your observations, it is easy to dismiss things as “not important” because they are so common or familiar. Be sure to include everything you see! Grey squirrels are common and easy to ignore, but make sure you include the common things when making your list. You’ll be amazed at the number of species you can already identify if you include everything!
2. Look On Things
It’s easy to look at a tree, identify it and move along. Don’t forget that trees are an excellent source of habitat for a multitude of species. The bark can provide crevices for beetles or lichens to hide in, birds build nests on the branches, or chipmunks build dens among the roots. Remember to look carefully at everything and think to yourself if there are good hiding places for things big and small.
3. Look Under Things
Underneath rocks and rotting logs is home to some of the greatest discoveries you might find! Snakes often hide under warm rocks to capture some of their heat. Salamanders and frogs will be found under rotting logs as moist hiding place. Beetles make their homes in an abundance of different types of cover. Be sure to leave no stone unturned!
Pick a spot, any spot. Sit down. Look in front of you. REALLY look in front of you. Breathe. Look again. Do you see it? A small snow drop hidden in the mud, emerging just in time for you to see it. I’m sure you’ll be amazed what you can find when you look closely. If you don’t know what it is, take a picture and share it on iNaturalist, we’ll see if we can identify it for you! When you really get down into the weeds, you’ll be amazed what you can find!
5. Look Up! Way Up!
Look up into the trees, there’s all sorts of life waiting to be discovered. Among the tops of the trees you might see a squirrel’s drey, a nesting bird or if you’re lucky maybe even a porcupine! Look even further into the sky, what do you see? Perhaps some passing Canadian Geese, or a Gull. Make sure to include everything you see!
6. Come Back Later
Many species of animals enjoy coming out at different times of day so make sure to come back in the morning afternoon and evening to see what different species you can find. Don’t forget to check in at different temperatures. Many species of insects are sensitive to temperature fluctuations, so come back at the warmest part of the day to see what else you can find.
Hopefully these tips help you get started on your journey to discover as many species as you can in your backyard! Don’t forget to log your sightings in one of the many citizen science applications! This March 28th, you can practice with the rest of Peterborough during the first ever backyard bioblitz!
