Logan Green Tree Planting

Eco-Buffers

The AWSA partnered with the City of Yorkton’s Environmental Services Department and Agriculture and Agri-Food Canada’s (AAFC) Agroforestry Development Center in Indian Head to plant over 3000 tree and shrub seedlings around the Logan Green Water Management System located along Queen Street in Yorkton in June of 2013. The seedlings, supplied by the prairie shelterbelt center, were planted as Eco-Buffers. Eco-Buffers are unique as far as shelterbelts are concerned, instead of planting multiple rows each    consisting of a single different species (e.g. a row of spruce, a row of caragana, a row of poplar), each of the 5 rows in an Eco-Buffer contains a mixture of many different tree and shrub species. The Eco-Buffers planted at Logan Green each consisted of 5 rows of various native Parkland species (a total of 17 different species were planted). Another key difference between Eco-Buffers and traditional shelterbelts is the spacing between trees. Eco-Buffers use a tight 1meter in-row and 2meter between-row spacing to   encourage quick ground coverage which minimizes weed growth and maintenance. The tight spacing is facilitated by the nature of the planting scheme- small and tall shrubs alternating with larger trees.  The idea is to create a natural looking planting that is more    resistant to devastation from insects or disease (e.g. if a spruce tree disease breaks out, only those single trees within rows will be affected as opposed to the entire row if planted as a traditional shelterbelt). Seedlings were planted using a tree planter pulled behind a tractor-over 600m of 5-row Eco-Buffers were planted.

 After the seedlings were planted they were covered with black plastic ‘mulch’. This mulch, which looks similar to a roll of black poly, is applied via a special applicator pulled behind a tractor that rolls the mulch over top the trees, burying the edges as it goes. Small holes are cut in the mulch and each individual seedling is pulled through. The idea is to create an in-row barrier that eliminates weed growth and thus increases seedling growth by eliminating competition. The black plastic mulch also reduces evaporation of water from the soil and warms the soil sooner in the spring, leading to an increased growing season for the seedlings. 

 A huge ‘Thank You’ goes out to Janna Lutz from AAFC for providing the seedlings and technical expertise required to make this  project possible, as well as Michael Buchholzer and Glenda Holmes  and their Environmental Services staff at the City of Yorkton for all their help with the planting/mulching and on-going care of the Eco-Buffers. This project was definitely a group-effort success!



Canon Evergreen "Logan Green-up" Project

The AWSA and the city of Yorkton were once again busy Sept. 17th, 2013 planting more trees around the Logan Green site. The planting was made possible thanks to a success AWSA proposal to Canon Camera's Take Root Program, presented by Evergreen. The AWSA received $5000 towards the tree planting and a Canon Powershot camera to photo-document their planting. 200 Balsam Firs and 250 Burr Oak were planted on areas disturbed by construction activities.
