BC GRASSLANDS The Grasslands Conservation Council of British Columbia (GCC) became a society in August 1999 and a registered charity on December 21, 2001. We are dedicated to promoting education, conservation and stewardship of British MAGAZINE OF THE GRASSLANDS CONSERVATION COUNCIL OF BRITISH COLUMBIA Columbia’s grasslands in collaboration with our partners, a diverse group of organizations and individuals that includes government, range management specialists, ranchers, agrologists, ecologists, First Nations, land trusts, conservation groups, recreationists and grassland enthusiasts. GCC MISSION: • to foster greater understanding and appreciation for the ecological, social, economic and cultural importance of grasslands throughout BC; • promote stewardship and sustainable management practices that will ensure long-term health of BC’s grasslands; and • promote the conservation of representative grassland ecosystems, species at risk and their habitats.

Message from the Program Manager Spread the Conservation Message! Brad Arner T his past year many people tried to battle the COVID-19 blues by getting out in nature. That can be a double-edged sword. More people will, supporters can play is share our social media pages and submit pictures of grasslands.

We are fortunate to have such a group that willingly volunteer their time and their collective wisdom to guide diversity of landscapes in BC. We can hope with us through the challenges of running a non-governmental organization. Our increased activity in our grasslands will come a greater appreciation, and members and volunteers give their time because they believe in the cause that’s where GCC can play a role. and it is inspiring to see such commitment.

Lifelong Learning and its Place in Range Management By Rachel Whitehouse Range Agrologist (P.Ag), CNRD Ministry of Forests, Lands, Natural Resource Operations and Rural Development (FLNRORD) A lmost 40 years ago, Schaffer (1985) noted that “ecologists will probably never be able to write down the complete governing equations for the order in chaos that is any natural system”. This continues to prove true as This was attributed to the reduction in the seed input via grazing and the removal of the the natural systems around us continue to change despite our best efforts. litter bed and associated seeds The British Columbia Institute of Agrology mandates a minimum number of via burning. professional development hours we must complete to maintain our status While this is only one study, as professional agrologists.

It is generally thought in PHOTO: Rachel Whitehouse cheatgrass management that if you can control the cheatgrass seed source for three years, you will see a downward trend by the fourth year. This project is in its early proposal stage and we hope to move forward and collaborate with First Nations, other government branches and Thompson Rivers University students. We hope this novel approach will remove a significant quantity of cheatgrass seeds and stop the positive feedback loop of cheatgrass encroachment in this grassland. As our remaining grassland fragments continue to degrade, now is not the time to sit back and watch what happens. Now is the time to seek solutions and implement the vast amount of research that has already been completed. REFERENCES Schaffer, W.M 1985. Order and chaos in ecological systems.

Trans Mountain Completing Work in the Lac du Bois Grasslands Protected Area By Trans Mountain D uring planning for the Trans Mountain Expansion Project (the Project), Trans Mountain identified potential environmental impacts associated with construction and determined mitigation methods to reduce those effects. Trans Mountain’s goal is to protect the environment, have as little impact as possible and, where we do have an impact, ensure we are returning the land to its original function. Trans Mountain has an area-specific reclamation plan for the Lac du Bois Grasslands Protected Area (Protected Area). The plan was prepared to meet Trans Mountain’s commitments to reclaim all areas disturbed by the Project, and has been created using best industry practices, in consultation with BC Parks and consideration of input from a variety of interest groups and stakeholders. The primary role of the Lac du Bois Grasslands reclamation plan is to protect the native grassland communities and dry parkland forests that occur in Trans Mountain Pipe proximity to the pipeline within the Protected Area.

A seed lot will not be accepted or used if it contains Prohibited Noxious or Noxious weeds; seeds from species not known to occur in the BC Interior; or seeds from species that may impact revegetation success (e.g., cheatgrass). Native seed mixes and a short-lived cover crop will be used to inhibit weed establishment, reduce soil erosion and re-establish species common to the Protected Area. Seeding will occur as soon as practical after construction following final clean-up activities – ideally, immediately following topsoil replacement. If final clean-up does not occur at the opportune seeding time, a cover crop will be seeded, and the final seed mix will be applied at the appropriate time.
