Scientific research for the conservation of the species
Activity necessary or beneficial to the species

The purpose of the study is to identify criteria for critical habitat designation for this species. We want to determine how much habitat and what configuration is required to maintain a population of plants. We will test for differences between population patches, particularly the importance of size and distance between patches. We will compare plants protected or not protected from seed predators, plant productivity, and the effect of year to year variation. Plant patches will be compared for genetic diversity. For germination testing, an experiment will involve monitoring approximately 200 plants growing in-situ, for 3 years. Approximately 10% of the seed produced by each of the 200 plants (2000 seeds) in 2008 and 2009 will be taken to the lab for germination testing. To determine how microsites affect seed germination in-situ, approximately 10% of the seed produced by up to an additional 10 plants in each of 2 population patches will be collected in 2008 and 2009 (for a total of 1500 seeds). 50 seeds will be scattered on the soil surface in fifteen 25cm x 25cm microsite plots and lightly raked in, preferably on the same day that seed collection occurs. Seedlings that emerge in 2009 and 2010 will be monitored. For genetic analysis, a single leaf from 25 individual plants in each of 25 population patches (for a total of 625 leaves) will be collected once in 2008, and stored in a dried state at AAFC Plant Gene Resources Canada in Saskatoon for up to 2 months prior to destructive sampling of DNA for population genetics analyses.

Affected Species:

Information is urgently required for recovery planning for the species and identification of critical habitat. This is the minimum sample size needed to test for differences between population patches. No impacts on any other protected species are anticipated from the proposed activities. All access to field sites will be on-foot, mostly in July and August after the nesting season of most migratory birds. No other plant species at risk have been identified in this study area. The collection of single leaves, on this perennial plant, for genetic analysis will have minimal effect on plant survival. All monitored seedlings will be left in-situ after 2010 to continue contributing to the population from which they originated. Raking will be carefully done to minimize disturbance to existing plants. By working with the largest known metapopulation in Canada, and making collections from less than 1% of that population, it is anticipated that impacts on the species will be undetectable. A portion of the seed collected is temporary and that seed will be returned to the same population.
