I've worked in Iroquois Park in Louisville, KY for just about 20 years. I'm used to the occasional Virginia Pine (Pinus virginiana) that has been planted there over the 120 years or so that the park has existed, but I hadn't paid attention to what else was blending in amongst them.

Until Wednesday.

As some fellow landscape architects and I were identifying trees within an upcoming construction project area, I realized that more than a few of the pines were NOT like the others. Here are some images showing the distinctly 3-needle bundles, longer needles, and different bark.

I have a hunch as to what this species is, but welcome contributions from conifer connoisseurs.
