Climate change impacts on growth of black spruce in western Canadian boreal forest
This study explored the effects of changes climate on the growth rate of black spruce in western Canadian boreal forests over a 55-year time from 1950 to 2005. A multiple linear regression model was run for tree ring data, mean annual temperature, and precipitation from three sites at different lati...
