In this project I looked into White spruce productivity in Alberta (data collected by the ABMI) in order to understand its relationship with various climate variables. This topic is of particular importance due to the imminent effects of climate change on the boreal forests. As high temperatures and droughts are becoming more prevalent throughout Alberta, white spruce is showing signs of decreased productivity and increased tree mortality. A possible mitigation that could combat climate change negative effects is assisted migration. This practice demands a thorough understanding of the effect of climate variables on white spruce to insure an appropriate seed donor selection for the new site. The results of this project show that precipitation are likely to have greater influence on white spruce productivity than that of temperature, and adaptations to moisture levels should be given priority when selecting for seed donor sites. In addition, when comparing the effects of temperature, the mean annual coldest month temperature appears to play a more significant role than the mean annual warmest month temperature, which suggests other factors might be important for understanding productivity (likely insect infestation). Yet, further analysis of temperature effect in hotter habitats is needed. I conclude that the factors that are most important to look for in donor populations are adaptations to dry conditions and drought, and possibly resistance to insect infestations since winter temperatures will fail to remove this threat as it used to in the past.
