Observations by srgalehouse

There is a planting of these pines in a local metropark. The trees have needles 3/fascicle, cones that are serotinous and remain on the trees for a long time, and trunks which often display epicormic sprouts.They have been ID'd by others as pitch pine, but the needle length, 6'' or longer, seems to rule out pitch pine. The photo with the ruler shows what I think is pond pine on top, with pitch pine below it. The trees occur in woods with an odd combination of these trees plus Scots pine, Douglas-fir, Norway maple, and native oaks. Any opinions as to their true ID?
