Scientists at the Canadian Forest Service - Atlantic Forestry Centre (CFS-AFC) have compared whtie pine (Pinus strobus (L.)) productivity from large, central Ontario (ON) and small, isolated Newfoundland (NL) populations from different latitudes. The declining population numbers and sizes of NL white pine have become an important conservation issue because they pose a threat to its survival as a naturally occurring species on the island (Newfoundland Forest Service 1997). A common garden experiment was used to quantify and compare adaptive traits of white pine from the two regions. The information gathered begins to address an issue of pressing concern to forest professionals: what are suitable seed-source (provenance) deployment strategies in light of climate change predictions?
