Monarch Butterflies: Take a closer look

July 15, 2021

Upcoming Event!

Join us on July 26th to conduct some citizen science of the monarch life cycle along the Nashwaak River in Fredericton. We will count stems of milkweed and examine them for eggs, caterpillars, chrysalises and adult butterflies. This will be part of the Mission Monarch International Monarch Monitoring Blitz.

Did you know milkweed is the only plant that provides food for the caterpillar of the monarch butterfly?

Keep reading to learn more about monarchs and what you can do to support their habitat!

Monarch butterflies are an iconic species at risk in Canada. Each fall, these beautiful butterflies set out on a 4,000-to-5,000 kilometer journey from Southern Canada to their wintering sites in the mountain forests of central Mexico. This is one of the longest insect migrations in the world! Each spring they make their way through the United States and back to Canada. To learn more about this endangered species, check out the WWF page on monarchs.

Milkweed is the only plant that provides food for the caterpillar of the monarch butterfly. Monarch’s lay their eggs on milkweed, and once they have hatched, the juvenile caterpillars feed on milkweed leaves. The caterpillars grow dramatically over 2 weeks, and then forms a chrysalis. After another 2 weeks, the adult butterfly emerges.

Unfortunately, this beautiful and resilient species is threatened by habitat loss. Disruptions to their migration are caused by climate change, and by the loss of native plants (including milkweed species) along their migratory corridors. Deforestation of their overwintering sites also threatens this species. Read more about monarchs and their journey to New Brunswick.

Planting either swamp or common milkweed, the two native species in New Brunswick, helps to provide this butterfly with much-needed habitat. Swamp milkweed is often preferable in a garden setting because it does not spread throughout the site. It requires moist soil to become established, so watering it throughout the first few years is recommended.

How to identify Swamp vs Common Milkweed.

It is Tree Planting Season!

May 17, 2021

Our 2021 spring planting season is off to a great start, with over 2300 native floodplain species including maples, oaks and planted at our Greenway restoration sites along the Nashwaak river.

Community volunteers hard at work during one of our popular tree planting events, May 10th, 2021. Thank you to all the amazing volunteers that helped!

Over the past two weeks, with the help of more than 50 volunteers, we have planted over 1693 native floodplain trees at Marysville and Neil’s Flats. These two properties, located north of downtown Fredericton and owned by the City are being stewarded by NWAI as part of our Nashwaak Greenway Project.

Most of the trees planted were silver maples, a native species that predominates in floodplain forests and bottomlands of the Nashwaak and greater Wolastaq watersheds. Red maple, and red oak were also planted.

Around vernal ponds and along the riverbanks in Marysville Flats 650 red-tipped willow and red osier dogwood shrubs were staked.

Together the trees and shrubs we have planted will serve to restore function to our floodplain and help mitigate both flooding and erosion, while also creating valuable habitat to support greater native biodiversity.

A big thank you to all our community volunteers, as well as the teams from the Department of Justice and Public Safety and the Gaia Project that came out to help! We could not do it without you!

This work is supported by the New Brunswick Environmental Trust Fund, the New Brunswick Wildlife Trust Fund, and WWF-Canada.

Tree planting can reduce flood risk, say wildlife and watershed groups (April 12, 2021)

April 13, 2021

Maples, oaks, willows and grasses touted to restore flood plains, reduce property damage and save wildlife

CBC News · Posted: Apr 12, 2021 5:02 PM AT | Last Updated: April 12

Simon Mitchell, the lead freshwater specialist with the Canadian World Wildlife Fund, says river restoration projects are urgently needed to reduce the impact of climate change and save aquatic species. (Shane Fowler/CBC)

The spring melt is winding down on the St. John River and so far there’s been no major flooding.

The Public Safety Department reports the river is well below flood stage and the five-day forecast calls for levels to continue to drop. Experts in river restoration say there’s a way to increase the chance future freshets will go smoothly, too. Simon Mitchell of the World Wildlife Fund and Natalie Deseta of the Nashwaak Watershed Association say planting trees, shrubs and grasses along the river and its tributaries can help reduce the risk of bad flooding in spring and from extreme rain events.

“When we’re thinking about flooding,” said Mitchell, “our biggest issue is the frequency and intensity at which these events come.” Mitchell is a habitat specialist who studies the St. John River and a vice president with the Canadian WWF based in the Nackawic area.

“We need to do everything we can to hold the water on the landscape,” he said, “whether it’s trees or wetlands which act as a sponge and then slowly release that water.” Mitchell commends groups like the Kennebecasis Watershed Restoration Committee and the Nashwaak Watershed Association for the work that they have been doing.

Turning Soggy Lawns Into An Oasis, Daily Gleaner (April 5, 2021)

April 8, 2021

John Chillibeck, Daily Gleaner

At this time of year, the small trench dug into a hillside doesn’t look like much, just a line with some withered plants breaking up the monotony of the lawn. But look closer, and you’ll notice the yellow grass just downhill from the channel isn’t soggy and pooling water like the dip in the lawn just a stone’s throw away. Walk over there, and your shoes are sure to get a muddy soaker.

The small project, about the length of a canoe, is an example of a rain garden, populated with native, perennial plants. The Nashwaak Watershed Association created it a couple of summers ago behind its offices at the Ville in Marysville, the old Alexander Gibson Memorial School, with the help of about 20 volunteers in about three hours. This week the organization launched an appeal to local businesses and organizations that want to build something similar that could act as a demonstration site and provide homeowners the opportunity to learn how to do such a garden themselves.

“A rain garden that contains native vegetation and grasses will capture runoff, be it from your roof or the surface of your lawn, and channel it to an area where it can accumulate and be sucked down by these plants into the water table, as opposed to it just flowing off into a drain somewhere,” says Natalie Deseta, the group’s restoration and outreach co-ordinator. “By filtering that water that would normally sog out or flood your property, you’re taking out a lot of things we don’t want in our water table.”

Those nasty things include road salt, dirt, oil, even feces that might pollute areas and be harmful to humans and animals alike. The plants also serve a dual purpose. “A modern lawn garden isn’t very friendly toward songbirds and insects,” Deseta says. “They are kind of deserts, in that they have so little biodiversity relative to native organisms. They starve the environment of food. So by planting one of these gardens, it’s a food resource and shelter for these organisms.”

The Ville’s rain garden contains only native plants, such as bladder sedge, red currant, Jack-in-the-pulpit, ostrich fern and Joe-pye weed, all purchased from Dave Smith who runs his Save a Native Plant business right out of his backyard in Fredericton. The association enlisted a permaculture designer who used a surveying tool to show them where to put the trench.

The garden now forms a barrage between runoff from a parking lot up above, preventing the tainted water from flowing to a storm drain in another parking lot below. Marieka Chaplin, the organization’s executive director, encourages people who are interested in rain gardens to check out the association’s brochure or look online for ideas. In some cases, water has to be channeled to the best spot, ideally on a hillside. Once the plants or rocks are put in, they do the rest of the work.

The cost of a rain garden depends on the size and scale, Deseta says. “If you really want to have a beautiful rockery and make it ornamental, you can spring big bucks for it. But it can also be something relatively cheap. Native species aren’t particularly expensive, and they’re not rare.” Beyond being good for the environment, she says such gardens are great for peace of mind. Even the tiny garden at the Ville is a riot of colour midsummer, with buzzing insects and chirping songbirds.

The more we naturalize our lawns, the more connected our habitats are for insects and our songbird friends. If everyone has even just a small patch in their lawn that’s friendly to native organisms, we’re helping the overall habitat.”

Our water temperatures are heating up! As summer gets into full swing, you will notice the water temperatures increasing. While this weather is great for people, it can cause extreme stress to a variety of animals, including species-at-risk Atlantic salmon. NWAI is working hard to remove barriers to vital cold water refugia that are essential to these animals for species survival. For more information on Salmon and thermal refuge, check out information from our collaborators at the Atlantic Salmon Federation . Much of our water quality monitoring work is funded, in part, by the Government of New Brunswick and NB Wildlife Trust Fund. www.asf.ca/news-and-magazine/in-the-field/cold-water-enhancement#atlanticsalmonconservation #climatechange #watershed #wolastoq #conservation #protection #ASF #ASCF ...
