Extremely common across central Indiana as a legacy planting — abandoned Christmas tree farms, 1970s-90s subdivision screens, and farm windbreaks — and now steadily disappearing from the landscape to pine wilt. You will find whole planted rows dying one at a time straight down the line.
Pine wilt has effectively ended this species in the Midwest — the pinewood nematode, carried tree to tree by pine sawyer beetles, kills a mature Scotch pine within weeks to a few months and there is no cure once it is inside. Extension services across the region no longer recommend planting it anywhere in the Midwest, so in practice nearly every Scotch pine call is a removal call.
