Description

Natural ecological communities are defined as recurring assemblages of plant species; the species occurring together because they respond similarly to a variety of site attributes (Grossman et al 1994). The species that make up the assemblage often show an affinity or association with each other (Kent and Coker 1992). To develop an initial tracking list of natural ecological community elements, publications describing vegetation in Alberta were reviewed and discussions were held with knowledgeable individuals. Community types that have been described as 'unusual', 'uncommon', 'of limited extent' or 'encountered infrequently' by vegetation experts were considered for inclusion on the Ecological Community Tracking List. Community types that have been described as 'in decline' or 'threatened' by vegetation experts were also considered for inclusion. Only natural communities were considered. The assistance many individuals in developing this tracking and watch list is gratefully...

Description

Alberta Sustainable and Resource Development initiated an inventory of small-flowered sand verbena and tiny cryptanthe in southern Alberta in July 2007, in order to obtain additional information on their populations, abundance and distribution. Priority areas for this survey included the Bow River populations, north of Medicine Hat, and near McNeill. Prioritization of these areas occurred because of the absence of other survey efforts covering these known populations of tiny cryptanthe and/or sand verbena.

Description

Several reports have been prepared on the status of Alberta's native plant species. More recently, nonvascular plants have been given some attention and tracking lists have been developed. There is a relatively good information base for rare vascular species but a very limited one for rare non-vascular plants. This report analyzes the vascular plant species and discusses potential approaches to research, monitoring and conservation of vascular and non-vascular plants in the Grassland Natural Region. There is a fundamental recognition that habitat or landscape level approaches are preferred but that some single species attention may still be required. One hundred and twelve vascular plant species were selected for detailed analysis and preparation of protocols based on their distribution within the Grassland Natural Region.
