I am currently researching the effects Russian thistle (Salsola kali), an invasive weed plant species, on native montane grasslands communities in Jasper National Park
Invasion of non-native plant species can have a significant impact on the function and integrity of natural ecosystems. In Jasper National Park, large areas of Russian thistle have been observed in native montane grassland communities used for winter grazing by bighorn sheep and other ungulates. There is concern that these areas of invasion may be increasing in size. Areas invaded by Russian thistle appear to coincide with areas subject to sustained use by sheep, elk and possibly deer. Critical areas are believed to be overgrazed, reducing range condition and permitting Russian thistle to become established and compete with, or replace, already stressed native plant species and reducing wildlife forage.
To manage and protect the ecological integrity within Canada’s National Parks it is important to fully understand how native plant communities within the parks respond to the influence of alien species and the role of herbivores in this process. Increasing the knowledge of native plant community response to a particular invasive species may lead to improved ecological restoration, and management methods. Potential overgrazing of winter range habitats may be facilitating the establishment of Russian thistle in native montane grasslands. This study examines the role of wildlife grazing and range condition on Russian thistle establishment. Outcomes from this study will assist park managers in determining appropriate Russian thistle control, as well as identifying ungulate management strategies for winter range use.
Specifically, this research project attempts to address the extent and character of Russian thistle infestations in the park, mechanisms of Russian thistle invasion, the role of wildlife grazing on Russian thistle establishment, how Russian thistle impacts native plant communities, and strategies that may aid in managing this species. Research results will benefit land managers within the park, and other park managers and land managers who are involved with ungulate grazing and invasive species.

Climate change has become a prevalent topic in ecological research since we are beginning to see the effects of warming temperatures on plant populations. In western Canada, research has already identified climate change as a cause for loss of local tree populations, for example through extreme drought events or indirectly through range expansion of pests and diseases. The International Panel on Climate Change suggests that the global temperature will continue to rise approximately 0.2oC per decade which raises the question if tree populations in a protected by a static network of reserves and parks are adequately protected.
The aim of my research is to determine how adequate the current network of protected areas w ill be in protecting native tree species in Alberta, British Columbia and Saskatchewan as Canada faces climate warming. By modeling tree species habitat under a variety of climate change projections, I will be able to identifying (1 ) how long the current network of protected areas will be able to protect native tree, and (2) whether any “future proof” reserves exist that maintain habitat under most or all scenarios. Conservation efforts should be targeted toward those areas.

Marilou Bourdages, Université Laval
CCEA is pleased to announce that Marilou Bourdages, a Master’s candidate with l’École supérieure d’aménagement du territoire et de développement régionalde l’Université Laval (Québec) is the second recipient of the Stan Rowe Home Place Graduate Award. The Award was originally established in 2006. Marilou was selected from a field of 13 applicants from across the country and covering a diversity of interests in protected areas design and management. Marilou’s research, which is being supervised by Dr. Claude Lavoie will focus on ” la flore vasculaire du parc national québécois de l’Île-Bonaventure-et-du-Rocher-Percé”. We look forward to hearing about progress on Marilou¹s research at the next CCEA AGM/Conference scheduled for Quebec City for September 17/18, 2008.
The applications for the graduate award were reviewed by a committee consisting of Dr. Joyce Gould, Alberta Parks, John Vandall, CCEA Treasurer and Dr. Rob Wright, Saskatchewan Environment.
The deadline for the next round of applications for the Stan Rowe Home Place Graduate Award is December 15, 2008.
Lee Anderson, University of Alberta
CCEA is pleased to announce that Lee Anderson, an MSc Candidate in Conservation Biology with the Department of Renewable Resources at the University of Alberta is the first recipient of the Stan Rowe Home Place Graduate Award for 2007. Lee was selected from a field of 17 applicants from across the country and covering a diversity of interests in protected areas design and management. Lee’s research, which is being supervised by Dr. Fiona K.A. Schmiegelow, will focus on the design of a network of protected areas in the boreal forest. The work complements a recent CCEA initiative dealing with “Protect Areas in Northern Canada:Designing for Ecological Integrity” We look forward to hearing about progress on Lee’s research.
The applications for the graduate award were reviewed by a committee consisting of Nik Lopoukhine, Chair of the IUCN World Commission on Protected Areas, John Vandall, CCEA Treasurer, Dr. Rob Wright, Saskatchewan Environment, and Peter Jonker, University of Saskatchewan.
