In the limited area from which this type is known in Maine, most of the jack pine forest has been clearcut within the last 25 years and is now growing back as young jack pine forest. In areas where mature jack pine has not been cut, regeneration is primarily red or black spruce.
Climate‐diameter growth relationships of black spruce and ... B.S.P.) trees in boreal Ontario, we modified an existing diameter growth model to include climate variables. Diameter chronologies of 927 jack pine and 1173 black spruce trees, growing in the area from 47°N to 50°N and 80°W to 92°W, were used to develop diameter growth models in a nonlinear mixed‐effects approach. Commercial thinning that maintained species diversity of a ... monospecific stands of black spruce and jack pine are among the most abundant stands in North American boreal forest (MRNF 2009). Moreover, many have reached the devel-opmental stage that is suitable for thinning. We hypothesized that species diversity enhances the pro-ductivity of mixed black spruce–jack pine stands because of a
