    I believe this is a birch. I am wondering if there is a way to clearly distinguish a birch from an alder at this time of year when there are no catkins or strobiles?

    Also, can you suggest a species?

    B. nigra...?

    Or something else altogether?

    Birch. Not sure what species, it'll be easier to tell when it is older and shows mature bark colour and has catkins.

    Thank you Michael.
    I will post photos when the catkins appear.

    If there is no information about the origin of the specimen it could even be a hybrid from seed collected in cultivation. Partly because birches are wind pollinated this happens often enough for wild collected seeds to be considered preferable. Otherwise of the much planted species I would compare this example to paper birch - which is actually native to the Vancouver area.
