Abstract

 Questionnaires were sent to almost 50 forestry representatives of federal, provincial, and territorial governments, industry, and universities across Canada, seeking information on eight categories of conservation activity: genetic/ecological conservation areas, reserved stands, seed production areas, seed orchards, clonal archives, provenance tests, seed banks, and "other." Information on national parks, wilderness areas, ecological reserves, and other in situ conservation activities outside the jurisdiction of forest services was obtained from published sources.
 Almost 676 000 km2, or 6.8%, of Canada's land area lies within currently designated parks or other reserves, and for 255 000 km2 no logging or other disturbances are permitted. Approximately 4% of the productive forest area is estimated to fall under the "highly protected" status for which no disturbance is permitted. In seed banks across Canada, 33 500 forest tree seedlots are in storage, comprising over 3.1 billion seeds, with an additional 260 tonnes of seed for which numbers of seeds were not reported. More than 28 000 familes are represented in more than 1800 ha of seedling seed orchards across the country. Clonal seed orchards contain almost 14 000 clones and cover over 1000 ha, while 43 100 clones are preserved in clonal archives. Although the peak period of seed orchard and provenance test establishment has passed, such activities will continue and represent an enormous capital of ex situ genetic conservation.
