Gary: Red pine is a difficult species to follow in the fossil record, because its pollen is not differentiated from jack pine. However, pollen viewer does show the millennial changes in distribution of red plus jack pine. They made the most northward retreat at the peak of the Holocene warm period, about 7,000 to 5,000 ybp, and then started advancing south and west during the last few thousand years. That advance has now halted due to habitat conversion, Diplodia blight, fire suppression, and reversal of the natural cooling trend in the climate. We do expect red pine to be one of the most sensitive to species to warming climate, but so far habitat conversion and Diplodia have caused greater retreat than the climate.
