Point Lepreau employees give a helping hand to Monarch Butterflies

Point Lepreau employees give a helping hand to Monarch Butterflies

Every summer, Point Lepreau Nuclear Generating Station welcomes some unique visitors. It’s an ideal stop for Monarch Butterflies as they re-fuel for their 3,500 km journey to Mexico for the winter. The butterflies will feast on the fields of Goldenrod, Aster and Thistle, along with Milkweed planted by Station staff.

These plants are both a home and food source for Monarch butterfly eggs, and then the caterpillars which they become. This summer, these caterpillars ate through most of the planted milkweed at Lepreau, helping them grow quickly into their pupal (chrysalis) stage. But, while observing their progress, Point Lepreau Environmental Specialist, Carolyn Campbell noticed that a number of the caterpillars might struggle to find sufficient foliage and secure place to survive their pupal stage and devised a plan.

“After meeting the naturalist folks last year I took a huge interest in monarchs,” said Carolyn. “When I saw the 50+ caterpillars on the small patch of bare milkweed I knew we had to help. As a result of that so many other people are developing the passion that I now have to learn more and help out. It has been amazing to watch.”

In nature, only 10% to 15% of all these caterpillars survive long enough to reach their chrysalis stage.  The caterpillars typically attach themselves to the underside of a leaf, and then shed their striped caterpillar skin, revealing a turquoise-green coloured camouflage which helps protect them against predators while they gradually change into their adult state inside this new cocoon-like state. To help these caterpillars beat the odds, Carolyn and a group of her peers at the Station worked quickly to build a special incubator for the caterpillars. By setting up this habitat for the caterpillars, Carolyn and team expect the likelihood of survival to be closer to 75% for these caterpillars.

Inside their new habitat, the caterpillars are set up on Milkweed clippings. Grated netting seals the top of the aquarium, providing a place for the larvae to weave a tiny silk pad that they’ll anchor the bottom of their abdomen to. They’ll hang here in this upside down position for 12 to 48 hours before extracting itself from its caterpillar skeleton and enter their pupal stage.

The caterpillars will remain in their cocoons for 8 to 15 days before they emerge as adult butterflies.

At first, the butterflies may be a bit weak. To help them get used to their new wings, Carolyn and team set up a special netting structure to place them to keep them safe while they get comfortable.

When they’re ready to take off, these butterflies will be tagged, with the help of the Jim Wilson of the Saint John Naturalists’ Club at their observatory on the Point, who has spent the last 12 years tagging these endangered butterflies. Once tagged, they will begin their journey to Mexico. Tagging helps provides data that is used to learn more about the migratory cycle and to protect it.

Point Lepreau is so important to the Monarch migration,” says Jim. “It has been a wonderful work with NB Power. We are very appreciative for this great relationship.”

The observatory at Point Lepreau is one of only two tagging stations in New Brunswick.

In 2017, Point Lepreau was designated an official Monarch Watch stop for these butterflies, due to all the undisturbed fields of pollinating species and the planted milkweed that the Monarchs need. Monarch Watch is a nonprofit education, conservation, and research program based at the University of Kansas that focuses on the monarch butterfly, its habitat, and its spectacular fall migration.

 

5 types of insulation you need to know to save energy at home

5 types of insulation you need to know to save energy at home

When looking at energy-efficiency upgrades as part of your home renovation, upgrading your home’s insulation will give you the biggest return on investment. In New Brunswick, 50% of an average home’s energy use goes to heating. Only 6% of the housing stock in New Brunswick is insulated up to the current standards of the National Building Code. Choosing the right home insulation type for your renovation will help you save energy at home during both the heating and cooling seasons. Read on to learn more about the 5 types of insulation you need to know to help you save energy at home.

How insulation works

When we heat or cool our homes, and they aren’t well insulated, our homes become less comfortable as the heat finds ways to escape (in the winter), and enter (in the summer). Insulation creates a barrier between the inside and outside of your home to slow heat from leaving or entering.

When looking at upgrading your home insulation, be sure to look at the r-value of your insulation. The r-value varies based on the type, density and thickness of the material being used. The higher the r-value, the better it will perform.

Home insulation types

  1. Blown-in insulation
    This home insulation type is usually made of fiberglass or recycled paper fiber (known as cellulose.) It’s blown or sprayed into place and is ideal for hard-to-reach areas such as attics or wall cavities you don’t want to open up.



  2. Insulation batts
    Precut sections of fiberglass or rock wool insulation. Can be used in floors, walls, attics and ceilings.



  3. Insulation rolls
    Similar to insulation batts, but come in longer lengths- usually 20-40 feet. This insulation type is ideal for attics, floors and other areas where you need longer runs.



  4. Foam board insulation
    This insulation type comes in rigid panels made of polystyrene and polyurethane. Can be used to insulate almost any part of your home, especially exterior walls underneath your siding.

  5. Spray foam insulation
    Latex or polyurethane spray foam can be sprayed either with a can to help seal around windows and doors, or through special equipment in areas like basements and crawlspaces.



How much insulation do I need?

The best way to find out how much insulation you need to add to your home is to have a certified energy advisor come to your home to perform an energy evaluation. You can register through our Total Home Energy Savings program to set up and evaluation and receive money back for upgrading your home’s insulation.

We recommend upgrading your home’s insulation to reach the following r-values to make your home more comfortable and help you save on your bills.

  • Attic: R-60
  • Sloped/Cathedral Ceilings: R-30
  • Exterior/Main walls: R-30
  • Basement/Crawlspace Walls: R-30

The 4th Annual Doug Wallace Memorial Slo-Pitch Tournament was held on August 11 in Saint John. The slo-pitch Tournament is an annual fundraising initiative led by Point Lepreau staff in memory of Doug Wallace, well known union member and long-time NB Power employee.

Eight teams made up of NB Power employees and community members participated in the Tournament, raising a total of $2,850 for Bobby’s Hospice of Greater Saint John.

Team Security came in first place with team Operations coming in second.

 

In first place was Security – Back Row from left to right: Anna-Marie Adams, Keith Garnett, Dylan Jones, Vinnie Hosford, Shannon Tapper, Chris Dempsey, Vance Crozier Bottom row left to right: Katrina MacKinnon, Joe Mahoney, Litsa Dares, Keri Savoie​
