Carp River iNaturalist Projects

To encourage and support citizen science, we have created seven projects in iNaturalist to capture observations made in and along the river and its four main tributaries.  Any observation made (except one that is obscured or private) is automatically added to one or more of our Carp River projects depending on where the observation is located.

One project is the Carp River Conservation Area, which covers the 2 kilometer restoration site between Richardson Side Road and the Queensway (Hwy 417).  It will support education and outreach programs for the Carp River Living Classroom.

Read more about the projects and how you can contribute on our Citizen Science page.

Signs of Spring at the Carp River Conservation Area

View over the wet meadows flooded by the spring freshet.

21 March 2020 – Early morning on the third day of spring felt like winter redux with an air temperature of -10C and a wind chill of -20C due to the icy blast from the northwest.  But the sun was too bright and too high on the horizon for winter.  Sunlight sparkled on the open water of the Carp River’s spring freshet flowing through the restoration site in Kanata.  Despite the cold and patches of snow, could signs of spring be found?



Honking. Quacking. Conk-la-ree! Early spring migrants blared a cacophony of bird calls.  Canada Geese and Mallards rested in the open water of the river and its wetlands.  Although some will stay through the summer, these birds are likely just passing through on their way north.  However, other birds have arrived from the south to make a home here.  A pair of male Red-winged Blackbirds wheeled over the marsh in a territorial battle, while another male nearby perched on a cattail and proclaimed his ownership of a plot of flattened rushes by the river.

Infinite Geese!

The large flocks all looked like Canada Geese, but close examination can sometimes reveal different species that travel with them like Brant Geese and Snow Geese.  Among all the black, brown, and white geese a leucistic individual was found.  Leucism is a genetic condition that affects the goose’s ability to produce the dark Melanim pigment so it appears white, light brown, or grey.

Red Osier Dogwood stabilizes the shoreline.

Yellow, red, orange, chartreuse. Willow twigs retain their colour in winter, but the colour brightens as sap begins to flow and buds swell. Willows are one of the first woody plants to bloom in the spring, providing much-needed nectar for early pollinators. Thirteen native species of willows grow in Ottawa, some as trees and some as shrubs. Common shrub willows at the restoration area include native Bebb’s Willow and Sandbar Willow. The large trees that grow on the site are non-native Hybrid Crack Willows, so called because their branches easily break.

Red Osier Dogwood’s pinkish-red twigs also brighten marshes and shorelines during winter, but these shrubs bloom and leaf out much later. Its white berries (bitter and mildly nauseating to humans) are eaten by a large variety of birds and provide a valuable source of energy for fall migrants.

Both willows and dogwoods stabilize shorelines to prevent erosion and sedimentation of the river.  They provide food and habitat for many species.

Don’t run away!  “Scat” is a term biologists use for animal poop. Piles of scat, some quite substantial, were deposited at intervals along the pathways. Close examination revealed these were from coyotes, not dogs. Coyotes are omnivorous.  Their scat looks dog-like, but it consists of seeds, hair, and bones, and it tapers to a long tail. Coyotes will use scat piles repeatedly to mark territory, hence the size of the piles. Red fox scat is similar, but smaller.  Coyotes inhabit the area all year round, but these scat piles were recently deposited on the bare pathway pavement.

Pack your binoculars and camera and visit the Carp River Conservation Area to see what you can discover.  Find out more about its pathways and how to access it here:  Carp River Conservation Area.

iWonder? Arcadia River Chase Park

Arcadia lies on the Ribbon of Life of the restored Carp River.

Greek mythology imagined Arcadia as a vision of pastoralism and harmony with nature*.  In Kanata, the new community of Arcadia lies on the doorstep of a riverine and wetland natural setting – a ribbon of life – along a two kilometer restored section of the Carp River.  How fortunate Arcadia is to be part of this large and unique natural area in suburban Ottawa.  What are its possibilities for realizing harmony with nature?
The Friends of the Carp River are working with the Mississippi Valley Conservation Authority, City of Ottawa, and Ottawa Stewardship Council to animate the restored river and its wetlands for education and discovery, a Living Classroom along the Carp River:

  • an education resource for schools,
  • a place for families to learn about wetlands and biodiversity,
  • a site for citizen science and research,
  • perhaps eventually an eco-tourism experience for visitors to Ottawa.

Beside the Living Classroom on the restored river lies a 6 acre parcel of land designated for a park in the Arcadia subdivision. River Chase Park will be built with recreation amenities to meet Arcadia’s needs.  But it can be so much more than just another suburban park.  It’s a gateway to nature, connecting the community to the pulsing vitality of riparian shorelines:  wading birds, pollinators and wildflowers, basking turtles, river otters, and the seasonal rhythm of migrating birds.

The Carp River Living Classroom lies on a 2 km section of restored river beside Terry Fox Drive between Richardson Side Road and the Queensway. Arcadia and its park lie to the south of the river.
Arcadia’s River Chase Park will be a gateway to the Living Classroom and Ribbon of Life along the Carp River.



iWonder – How can Arcadia’s park be:

  • a place for inspiration, recreation, gathering, and learning?
  • integrated with the river, wetlands, and wildlife?
  • a celebration of the ribbon of life?
  • an experience that is about more than just playing or watching a game?
  • a place for meditation, contemplation, and well-being.

The community will decide what play structures, sports, and other recreation activities go into River Chase Park.  However, the community also has an opportunity to enhance their park experience by incorporating design features that integrate the park with its remarkable surroundings, within budget constraints.
This opportunity comes about through the partnership of organizations who are developing the Living Classroom.  We are talking with Councillor Jenna Sudds and the Arcadia Community Association to explore the possibilities for the park.
The Living Classroom is a multi-year project that will be launched later in 2020 along with a fundraising campaign.  Part of the Living Classroom vision requires a River House – a gathering and education place.
This is Arcadia’s opportunity to create a unique park experience in Ottawa.  We will continue to explore the possibilities with the community to live in harmony with and celebrate the ribbon of life in its backyard.
Councillor Sudds will be hosting a community session in Spring 2020 and a consultation website will be launched to gather community input.
