July 19, 2019 – It’s a great time to be outdoors, but be aware: certain pests and poisonous plants are getting in on the action, too.

As you hit the trails, remember to stay on the path and dress appropriately to protect against ticks, poison ivy, wild parsnip and other hazards.


Black-legged ticks are on the rise in Eastern Ontario and can carry Lyme disease, which is passed to humans through tick bites. Left untreated, Lyme can cause chronic neurological and physical problems including memory loss, mobility issues and heart conditions.

But don’t let that keep you inside! Reasonable precautions should prevent most tick bites. When you’re in the woods, stay on the path, wear long pants and sleeves, tuck your pants into your socks and use bug spray with DEET or picaridin. A quick sweep of your clothes with a sticky lint roller before you go home will help catch errant ticks. When you get home, do a thorough tick check of your entire body, including in your armpits, groin area, behind your ears and along hairlines.

If you do find a tick attached, remove it as soon as possible. Contact your doctor if the tick looks engorged or you think has been attached for a long time, to see if you need antibiotics.

If the tick was attached for less than 24 hours and its body does not appear swollen from feeding, you should still be on the lookout for signs and symptoms of Lyme disease for the next 32 days. If you do develop symptoms, see a doctor.

Poisonous plants:

Poison ivy, wild parsnip and giant hogweed all have a presence in Eastern Ontario, lining roadside ditches, taking over empty fields and popping up along nature trails and woodlots.

Touching these plants or their sap can result in painful skin rashes and burns, particularly wild parsnip, which is sun-activated and can cause severe burns and even blindness in extreme cases.

Wear long pants and sleeves, close-toed shoes and socks. The sap from these plants can contaminate your clothes, so be careful when undressing and handling your clothes after an outing.

If you do come in contact with the plants, wash the area with soapy water and stay out of the sun. If the sap gets in your eyes, wash immediately and contact a doctor.

Of course, it’s important to know what to look for so you can avoid these issues altogether.

Poison ivy is perhaps the best known of the three plants. It can grow between 10 and 80 centimetres high, and its leaves range from 8 to 55 millimetres long. Poison ivy leaves feature three pointed leaflets – usually toothed – with the middle leaf being much longer. The leaves are reddish in the spring, turn green in the summer, and become various shades of yellow, orange, or red in the fall. The plant produces clusters of cream to yellow-green flowers.

Wild parsnip can grow up to 1.5 metres tall, with a thick, smooth stem topped with green-yellow flowers forming clusters up to 20 centimetres across.

Giant hogweed looks similar to wild parsnip but grows up to five metres tall in some cases. Its white flowers are clustered in groups between 30 and 90 centimetres across, and its thick stem often features prominent purple blotches.

Remember: There’s so much to see and do in the Rideau Valley watershed – don’t let these spoilsports get in your way! Take precautions, stay on the path and, most importantly, have fun.

June 24, 2019 – Ah, summer: a time for relaxing with friends, soaking up the sun and, of course, hitting the beach.

But sometimes beach days are more hassle than relaxle: fighting traffic, circling for parking and dodging rogue frisbees while you defend your tiny square of sand from the hordes of other beachgoers. Some fun!

But there’s a solution: instead of wasting 30 minutes parking, spend it heading to Baxter Conservation Area in Osgoode, Rideau Ferry Yacht Club Conservation Area near Smiths Falls or Foley Mountain Conservation Area in Westport for a beautiful beach day away from the crowds.

Just 20 minutes from urban Ottawa, Baxter offers one of the cleanest, prettiest beaches along the Rideau River, complete with ample picnic tables, barbeque pits and green space to settle in for the day.

When you’re tired of toasting your toes in the sun, you can stretch your legs along five kilometres of easy walking trails and boardwalks through sun-dappled forests, meadows and wetlands. And kids (or kids at heart) can scan the buzzing Baxter Pond for leopard frogs, minnows and other curious creatures, too.

Rideau Ferry wins our Best Beach award: the beautiful, clean swimming area on Lower Rideau Lake is hardly ever crowded, and is less than an hour from urban Ottawa. Make a day of it and enjoy the many picnic tables and grill pits.

Foley Mountain’s beach is also well worth the drive to Westport considering the property includes 11 kilometres of trails and a stunning view of the region from the famous Spy Rock. Work up a sweat before diving into the refreshing waters of Upper Rideau Lake!

Honestly, with all these fun activities, you may never want to leave (but please do, because the parks close at dusk).

And on top of all that, it’s great bang for your buck: parking is only $7 for the day or $50 for an annual pass, valid at all of our paid parking lots across the watershed.

See you on the sand!


June 21, 2019 – Twelve classes of low-income students will experience the natural world first hand – some for the very first time – thanks to a generous grant from the Ottawa Community Foundation.

The Rideau Valley Conservation Foundation is campaigning to help 50 disadvantaged classes access its outdoor education programs during the 2019/2020 school year. The grant of $9,420 from the Ottawa Community Foundation will cover tuition and transportation costs for 12 schools from the city of Ottawa.

Each year, the Rideau Valley Conservation Authority welcomes more than 10,000 elementary and secondary school students to its Outdoor Education programs at Baxter and Foley Mountain conservation areas. The curriculum-based sessions taught by certified teachers give students hands-on experiences in nature while they learn about natural science, our role in the natural world and how we can protect it.

But not all students can afford the same experiences as their peers; there are at least 37 priority schools in the Rideau Valley region where funding simply isn’t available for “extras” like outdoor education. Unfortunately, it’s these students who are often missing natural experiences the most: many of them are new to Canada or live in urban communities where walking among the trees, exploring a wetland or catching frogs is completely unknown to them. That’s where the Foundation and its generous donors come in.

There is a growing body of evidence that learning through outdoor active play has positive effects on a child's physical, emotional, and intellectual health. More and more, children suffer from “nature deficit disorder” – a lack of connection with the natural world.

Staff use the Ministry of Education’s list of priority schools – determined based on national census income data – and work with local school boards directly to identify schools that would benefit from financial support to get their students outside and into nature.

ATR - May June 2019

June 19, 2019 – Our hardworking forestry team has wrapped up another successful tree planting season, and they’re already looking ahead to next year.

The Rideau Valley Conservation Authority (RVCA) is now booking site visits with landowners wishing to reforest their retired farm fields or otherwise empty and idle lands.

The low-cost, full-service program includes free site visits, custom planting plans, site preparation, tree planting, follow-up assessments and maintenance to give the seedlings the best chance of survival. All of this is available for only $0.15 per tree, or $120 an acre!

“Increasing forest cover is critical to watershed health, but so much of the land is privately owned,” said forestry program manager Scott Danford. “This program offers landowners easy and affordable tree planting services while helping us meet our larger watershed management goals.” 

This year Danford’s team planted about 200,000 trees across the region. The RVCA has planted 6.4 million trees since 1984 and aims to hit 6.5 million in 2020.

“The RVCA staff have been a pleasure to work with since we started in 2014,” said Maberly landowner Peter Ginsberg. “I'm very happy with this program that made it possible for us to help support the planting of almost 12,000 trees on our property.”

The forestry team is booking site visits this summer to plan for the 2020 spring planting season. The planting area must be at least one acre in size, suitable for tree planting and the landowner must be willing to plant 1,000 trees or more.

Typical costs are $0.15/tree ($120/acre). The RVCA and its planting partners cover all other costs.

“We have several community-minded partners who support our tree planting program,” said Danford.

Planting partners include the City of Ottawa’s Green Acres program and Forests Ontario, Mississippi Valley Conservation Authority, Eastern Ontario Model Forest, Pratt & Whitney Canada, McGarry Funeral Homes, Stingray LiVE 88.5, Carleton Refrigeration, Pratt & Whitney Canada and the Rideau Valley Conservation Foundation also contribute to the forestry program to keep costs low for landowners.

Tree planting is one of the most practical ways to take care of our watershed and the wider environment. RVCA’s reforestation programs are a great way for landowners to improve their property by:

  • Protecting soil from erosion
  • Improving water quality
  • Reducing the risk of flooding
  • Carbon sequestration
  • Improving wildlife habitat
  • Increasing biodiversity
  • Water conservation and so much more!

If you want to plant trees, book a site visit or to get more information, call Scott Danford at 613-692-3571 or 1-800-267-3504 ext. 1175 or email .


June 14, 2019 - Everyone wants a nice, quiet spot where they can get away from it all, without driving hundreds of kilometres into the woods. That will become a reality this summer at Chapman Mills Conservation Area with the installation of a new, accessible public dock.

Thanks to a generous donation to the Rideau Valley Conservation Foundation (RVCF) from Cabela’s Canada Outdoor Fund, the installation will replace the conservation area’s old dock in a more accessible location, creating a better place to catch a fish, launch a canoe or just dip your toes in the mighty Rideau River.

The Rideau Valley Conservation Authority (RVCA) owns and manages the conservation area off Winding Way and Prince of Wales drives. Conservation Lands technician Megan Dunster said the property’s current dock and water access set-up is damaging the fragile shoreline as anglers and paddlers find more convenient ways into the water.

The new dock will protect the shoreline and intends to meet accessibility standards for slope and width. 

Dunster said there’s a shortage of public fishing spots in the city of Ottawa, particularly along the Rideau River. The new dock will allow the thousands of families who live in south Ottawa to take part in the sport – some for the very first time.

“I firmly believe the more that people can experience the outdoors, the more they will care about maintaining a healthy environment for themselves and for future generations,” said Dunster. “This connection is essential to the RVCA’s goals for a healthy, sustainable watershed.”

The dock project will include interpretive signs about fishing in the Rideau River.

Cabela’s Canada Outdoor Fund provided more than $4,800 for the project through a partnership with the RVCF, a registered charity which supports the RVCA’s conservation and watershed management goals.

June 10, 2019 – Planting trees and shrubs along your shoreline can protect your property from flood damage – and the Rideau Valley Conservation Authority is now booking site visits to help get the job done.

The RVCA’s Shoreline Naturalization Program offers landowners low-cost technical guidance, project management and all the native trees and shrubs you need to build a robust natural buffer along your waterfront.

These strategically-placed plants have hearty roots that hold soil in place so it doesn’t wash away during periods of high water, or in high-wake areas. There’s no need for expensive rock “rip rap” or other high-tech engineering – Mother Nature already knows what to do.

A three-metre natural buffer also discourages geese, reduces runoff and provides crucial wildlife habitat.

This spring, RVCA staff installed a total of 11,500 native plants on 63 private properties across the watershed. They also worked with a number of community groups to naturalize public shorelines.

Staff are now booking site visits for the 2020 spring planting season, and this year waterfront residents in the Tay Valley subwatershed can participate completely free of charge.

How does it work?

RVCA staff will visit your property between June and October to discuss your vision and assess planting potential. Then they’ll develop a unique plan for your property, including recommendations for the best native species for your property’s growing conditions. They’ll also discuss how you’d like to maintain your water access, seating areas and view.

From there, you can choose which subsidized plants you’d like based on your custom planting plan and the RVCA’s available species list, and staff will order them for you. In spring 2020, staff will deliver your plants and, if you choose, even do the planting for you!

Why naturalize?

Ninety per cent of all river life depends on a healthy shoreline to survive. But this “ribbon of life” also plays a crucial role in filtering out pollutants, reducing erosion and easing flood risks. By adding a natural buffer between your home and the water, you are protecting the health of our drinking water, ecosystems and shores.

JUNE 6, 2019 – A  new batch of butternut seedlings have been sent into the world to help pull the endangered tree back from the brink – but this spring’s lot may have been the last.

Landowners flocked to the Rideau Valley Conservation Authority’s specialized cold storage facility on Dilworth Road this spring to pick up their baby butternut trees, carefully grown at the Ferguson Forestry Centre from resilient seeds harvested across Eastern Ontario.

Butternut trees in Canada and the US have been decimated by the butternut canker, an incurable fungal disease scientists believe originated in Asia.

Since 2005, the RVCA has planted a total of 29,000 new butternuts across Eastern Ontario, partnering with landowners and other groups willing to plant the fragile trees on their properties.

But that could end now that proposed changes to the provincial Endangered Species Act have been signed into law.

The new rules, included in the Province of Ontario’s Bill 108: More Homes, More Choice Act, will allow developers to pay into a province-wide conservation fund instead of supporting localized, targeted efforts to save or replace the threatened species they disrupt. It’s unclear how the provincial pool of money would be doled out: money paid for local butternut destruction may no longer fund local butternut recovery.

That could leave the RVCA’s program without the critical funding it needs to collect resilient seeds to nurture new seedlings for reforestation. And it’s been a hugely successful model, if only because landowners have been so eager to plant the disappearing trees.

“I haven’t had a butternut on my property for more than 60 years,” said Mountain resident Fred Baker, who participated in the program for the first time this spring. He picked up 20 seedlings on May 10. “It’s a good, natural food for animals and wildlife, beautiful wood to work with, great saw logs if you can get them to that size. They’re beautiful to sit under.”

But even so, progress is achingly slow: of the 2,000 free seedlings handed out this spring, only about 30 per cent will live to age five, according to program manager Rosemary Fleguel.

“It’s a slow, steady drip to get butternuts back onto the landscape,” she said. “It’s still 30 per cent more than what was there, and they’re from genetically superior parent trees. What we don’t know is how many of these seedlings will be able to fend off the canker disease into maturity to produce seeds of their own.”

Fleguel estimates that 50 to 60 per cent of the population in eastern Ontario has died or is no longer reproducing since she started monitoring the trees in 1992.

“I’d say about 50 per cent still exist as viable trees, but every year a certain percentage fall off the edge,” she said. “The urgency to find these tolerant trees cannot be overstated.”

Model for the future

Fleguel’s job is largely focused on searching out healthy, pure butternuts that show signs of resisting or tolerating the canker disease.

She collects their leaves for DNA testing to ensure they are pure butternut and then collects their seeds to produce vigorous seedlings destined to replace the dead and dying butternut populations in the region. The RVCA recovery program also partners with the Forest Gene Conservation Association (FGCA) and assists in the cloning of these tolerant trees to save their genetic material. The clones are planted in five archives across southern Ontario and produce seeds for new, tolerant seedlings.

All of this takes place at a special greenhouse at the Ferguson Forestry Centre, where professional forestry technicians care for the grafts and tend them for years after they’ve been planted into the archives.

Fleguel said this is the program’s real success story.

Archiving material from disease-tolerant trees is a safeguard against extinction, she said, for two reasons. First, the saved genetic material will increase researchers’ full understanding of the disease and the butternut species so they can develop new and novel ways to save the species. For instance, DNA markers could more accurately identify tolerant trees, which would streamline the cloning process and capture many more trees for archiving.

“Seed collection can then increase 100-fold, because we’ll know for sure which trees have the DNA to reject the disease,” Fleguel said.

The genetic research has yet to catch up; butternut isn’t highly valued the way oak or maple is, so very few research dollars are funnelled into its salvation.

But the model for butternut can be applied to other endangered trees in the future.

“The template we’re developing can be transferred to other struggling tree species in the queue, like beech or ash,” Fleguel said. “If we are successful, people will be looking at this program in 50 years and saying ‘Wow, we really did something special here.’” The children and grandchildren of this year’s landowner participants might enjoy some quiet reflection under the shade of one of those trees in 50 years, or collect nuts from them in 30 years.

Fleguel called proposed changes to the Endangered Species Act “extremely short sighted,” noting residents and developers are just starting to see environmental protections as necessary and the norm – just as it took time for seatbelt laws to become the norm in the 1970s.

“To take it away now, we’re undoing a lot of progress at a time when biodiversity needs to be championed, not abandoned,” Fleguel said.

June 4, 2019 – The Rideau Valley Conservation Authority (RVCA) is maintaining a High Water Safety message for properties around Bobs Lake and Christie Lake.

The water levels on Bobs and Christie Lakes continue to decline slowly but both lakes are still above average for this time of year. This water levels are expected to gradually drop down to seasonal levels soon. Parks Canada staff are closely monitoring the water levels in these lakes.  Operations at the Bolingbroke Dam will take place as required to balance the levels in Bobs Lake and Christie Lake.

Water levels continue to be at seasonal values in the rest of the Rideau Valley Watershed.

Everyone needs to be cautious around lakes and streams with the fluctuating water levels. Children need to be educated about the hazards and kept away from all watercourses.

This watershed conditions statement is in effect until Tuesday June 11, 2019 at 5 PM. No further updates will be issued unless the forecast or conditions change.
