Buckthorn Busting and Pot-Luck Lunch Party, Nov. 23

Join us for our last session of the year, Buckthorn Busting on November 23 (RAIN, SNOW OR SHINE). We will celebrate all the great work we have done throughout 2014 at our annual  pot-luck lunch.

Please meet us in front of the Grenadier Restaurant at 10:30 am. We will go to our site from there so please try to come on time so you can find us. If you are bringing food, you may leave it at the Greenhouse, starting at 10:00 am.

Organizing lunch will be easier if when you receive the invite you RSVP (if YES) and enter what you want to bring in the Messages section which will now be visible to you. This way everyone can all tell what is needed based on the replies. If in doubt, don't worry about it, just bring something you would like to share, everyone is welcome and there is always lots of food. Since there is only one small microwave, items that can be served cold or at room temperature are preferred.


If you have any suggestions on improving our program we can share that too. Our winter presentations start on January 11. 2015.

More on Buckthorn: This highly invasive shrub forms dense even-aged thickets that often cause an overall reduction in the establishment of shade tolerant native shrubs and herbs. It rapidly produces seeds early in the season that are highly viable and germinate quickly.

Invasive Species we have come to know very well


Monarch Butterfly larvae can only survive on the Milkweed family of plants. This includes Common Milkweed, Butterfly Milkweed and Swamp Milkweed, all found in High Park. DSV aka Pale Swallow-wort is similar in structure (see the pods) but when Monarch mistakenly lay eggs on them, the larvae die when they eat it. DSV is a major concern as it is extremely aggressive and will grow back multiple plants if some of the root is left behind when pulled.

The Boulevard Bed Squad will be determining their schedule, with monthly maintenance of the beds spring to fall. Contact

Outdoor sessions are dependent on weather and growing conditions and what is determined to be the greatest need for our volunteer efforts.


2013 in Review

In 2013, much of our work took place in the Tablelands, a beautiful example of the remnant Black Oak Savannah, which is an endangered ecosystem that needs to be preserved and protected. Both the spring and fall planting events were held in the fenced restoration area just northwest of the Labyrinth. A secondary spring planting was held in the 10A restoration site near Bloor Street.

The Tablelands, which at one time was a mown lawn, now shows promising signs of natural regeneration of red and black oaks, and rebounding populations of native tall grasses such as Big Bluestem, Little Bluestem, and Indian Grass, as well as typical savanna wildflowers such as Wild Bergamot, Woodland Sunflower, and Black-eyed Susan, legumes such as Showy Tick Trefoil and Round Headed Bush Clover, and shrubs such as New Jersey Tea, St. Johnís Wort, and Smooth Rose.

Invasive species removed this year include: garlic mustard, tall white sweetclover, hedge parsley and Asiatic bittersweet. Native ragweed was also removed in the Tablelands. This fall over 3 sessions, Common Buckthorn was busted in 7B and 8A.

Over the three planting events, we planted a total of 2,575 plants.

Over the three buckthorn busters events, we removed buckthorn from a total of 8,000m2 in 7B and 8A.

These are huge accomplishments, which help to move us forward in our mission of ecological restoration. Much thanks to all volunteer stewards for an excellent season! Enjoy the holidays and we hope to see you all next year.

Sharon Lovett Chair, High Park Stewards,


Many thanks to all of our volunteers who participate in our program. We've weeded, planted, collected and cleaned seeds, provided a native plant sale, maintained the Boulevard Beds, Sculpture Garden and All-Star sites, removed garlic mustard, hedge parsley, Himalayan Balsam and Buckthorn, and learned and taught each other about the flora and fauna found in the park. We also thank the city staff in Urban Forestry and Horticulture who do this work full time and guide us as we improve our stewardship capabilities. We know that we will have another successful year in 2012 protecting and supporting nature in High Park (and beyond).

TWEETERS WANTED. @highparksteward is looking for more people to help with this project. Tweet directly or you can contact us at
