Chapter 1, Table 1.13B. Shrub species scientific names are according to Wild Species Canada. Information presented in this report was obtained through literature searches, personal communication with experts and reflects the data that is available as of 2012 unless otherwise stated. A jurisdictional survey was conducted with participation from Alberta, British Columbia, Manitoba, New Brunswick, Nova Scotia, Prince Edward Island, Quebec and Saskatchewan, in order to obtain data pertaining to such areas as ex situ and in situ conservation and this data is current as of 2010. 5 Executive Summary Canada is one of a few countries that still have large tracts of forests that are relatively undisturbed by human activity and are believed to contain much of their native biodiversity. In Canada approximately 400 million hectares of land is forested or has forest cover, representing 10% of the world’s forest cover and 30% of the world’s boreal forest. Of this forested land, 93% is owned by the public (77% provincial/territorial and 16% federal), while the remaining 7% belongs to private landowners who range from woodlot owners to forest companies. The provinces and territories have legislative authority over the management and conservation of provincial/territorial owned forest land. The federal government is responsible for matters related to the national economy, trade and international relations, and federal lands and parks, and has constitutional, treaty, political and legal responsibilities related to Aboriginal peoples. Forest ecosystems in Canada contain approximately 126 native tree species, depending on the definition of large shrub vs. small tree. In general, actions taken to survey and inventory intraspecific variation of tree species vary greatly depending on the organization conducting the work and much of the research assessing intraspecific variation is collaborative across various federal and provincial agencies, universities, and industry. Organizations such as the Canadian Forest Genetics Association (formerly the Canadian Tree Improvement Association, which was established in 1939) have had a significant impact in fostering collaborations to—among other research areas—assess intraspecific variation within Canada. Also the pan-Canadian group CONFORGEN (Canadian program for the Conservation of Forest Genetic Resources), a federal–provincial/territorial collaborative group that monitors and reports on genetic resources of native tree species in support of Canada’s national and international commitments promotes, where possible, research assessing intraspecific variation. At a national level, information systems that contain data pertaining to intraspecific variation include NatureServe Explorer and the Canadian Forest Genetic Resources Information System (CAFGRIS) which is deployed through the National Forest Information System. Many jurisdictions and universities maintain databases with information pertaining to intraspecific genetic variation patterns (e.g. University of British Columbia’s Centre for Forest Conservation Genetics and Arborea (Laval University)). Improving the understanding of intraspecific variation is recognized as important for the sustainable management of forest genetic resources. It is recognized that monitoring changes below the species level provides necessary information for ensuring that the species’ adaptive potential is maintained so that species can evolve in response to changing environmental conditions. Ensuring that species can respond to environmental change is a priority for much of the forest genetic resources research conducted within Canada. Furthermore, although it is recognized that landscape-level management of forest genetic resources will ensure the conservation of genetic diversity in some cases, there are forest types occurring over small areas where this approach is not appropriate. Capacity building needs include stable investments in research to develop methods for assessing interspecific
