For the Love of Plants (Part 1)

One plant group I love the most are Lichens. Lichens are technically NOT a plant, as they are only occurring thru a photosynthetic partnership between fungi and algae or cyanobacteria. Lichens don’t have a vascular system, and typically spread through spores or fragmentation. Lichens don’t have any organized leaf, root or stem structures; they are only equipped with hyphae and mycelium (which are the vegetative part of the fungus). Lichens grow in 6 different forms, including crusts, scales, leaves, clubs, shrubs, and hairs.

There are over 500 lichens species in Alberta’s forests, but my favourites are Cladina mitis (reindeer lichen) and Cladina stellaris (Northern reindeer lichen). They are very similar to each other, with key distinguishing features being their colour and shape. Reindeer lichen is pale yellowish green, and forms mats on ground, whereas Northern reindeer lichen is yellowish white, grows upright & reminds me of cauliflower.

We will continue with our love of plants posts all month long!

What Are Green Roofs?

Green roofs are a means of utilizing, typically, unused space by growing vegetation on building rooftops. Green roofs are a collection of materials, including vegetation, growing medium, drainage filter, etc. These can be extensive by retrofitting them on existing building roofs or intensive through practices of incorporating them into the design of new buildings. They have a range of applications including capturing excess stormwater, aesthetics, insulation, wildlife habitat, and local food production. Check out the City of Edmonton website for more information and where green roofs are already established in the city.


Bunchberry Meadows now open

The Nature Conservancy and Edmonton Land Trust made this happen. With the warming weather make sure you check out this place. It's a 250 hectare conservation area of native Parkland located just west of Edmonton.

2017 Highlights

Here are a few tidbits from last year's field season!

Shruti, our Sustainable Business Intern in Local Promotion, Marketing and Sales put together this booth for the Bloomin' Garden Show. Thanks so much for your help!

2017 was a final acceptance certification year for our ponds at Aurora-Walker Lakes. So we made sure everything looked the best it could be!

Next up was the Graydon Hill overflow pond. I wanted to make sure I snap a picture of the spring flooding before water disappeared later in the season.

Our 2nd final acceptance certification last year was at the Riverside SWMF in St. Albert. Only two years after construction completion, the site is progressing very well! I would say the life soil transfer was a huge success!

You might have also seen us at the downtown Edmonton and St. Albert farmers markets. I know I know, the hats are awesome!


Bare with me as I am trying edit this video. Apologies for blabbering in German. I was simply wishing Dan farewell ;)

Lastly, we planted a new site in Heritage valley in the fall. Hopefully Towne Centre will flourish next spring!

Happy New Year from Clark Ecoscience!
