    These trees all have fascicles of two, and the needles are around 5cm long on all of them, with a bit of variation. I'll bet at least one of them is a Shore Pine, Pinus contorta, but how many are that, and what are the others? The trees are close to each other behind the Aquatic Centre, on the seawall.

    Tree 1

    Tree 2 - the male flowers were distinctly more orange than on the previous tree.

    Tree 3 - this one doesn't look all that contorted. Is this Scots Pine, Pinus sylvestris?

    I'm thinking P. sylvestris.

    They're all Scots Pines. Shore Pine is never that glaucous, and has a different branch structure and cones.

    Thanks, Ron and Michael. They looked like three different trees to me. Maybe if I had first seen this one I just saw yesterday at UBC BG, I'd have thought they all in some way looked like this.

    The ones common in local plantings that are more similar to P. contorta are the taller, more erect expressions of P. mugo. Some of these have the hat-like umbos of uncinata and others don't. I have seen P. mugo that were quite broad and others that were pretty tall.
