Pink slime inside dead Elm from property next to a gas station
My neighbour, who lives next to a gas station, recently cut down some dead trees along the shared property line. We suspect, given the fact that the gas station has been around since the 1920s, that the ground is contaminated and the trees have soaked up decades worth of oil, gas, diesel, and other fossil fuels and made the inside of the tree pink. I've posted a link to some pics below.
Can anyone confirm if this is in fact gas? Would anyone know the name of the disease? Is this the likely reason for the tree's death? It was an old Elm tree..... (no, it's not likely beetle-borne Dutch Elm disease).
