Henderson Interpretive Trail #12
Douglas Fir
What are the trees around you? In this spot, several of the trees are Douglas fir. While not a true fir, this tree can be confused with one of a similar name, grand fir.
To identify many conifers, start by looking at the needles. In both Douglas and Grand fir, the individual needles are flat, with two light lines running the length of the underside. To conclusively tell the difference, look closely at the tip of the needle. If there is a tiny notch, it is a true fir like the Grand fir, but if there is no notch, it is likely a Douglas fir (or possibly a western hemlock, which grows on the north slope of Henderson Hill). The grand fir is the only true fir growing in the Southern Gulf Islands.

For another clue to the tree’s ID, look under the tree for cones that have fallen on the forest floor. The Douglas fir cone is quite distinctive, with papery scales and 3 pointed bracts extending beyond the scales. Many people say to “look for the mice hiding in the cones”, as they bracts look like two tiny feet and a long tale sticking out from under each scale

Did you know Douglas fir forests have some of the highest bird counts in North American forests? Many birds rely on the conifer seeds, tree cavities, and nesting habitats that Douglas fir provide. Here are some of the birds you might find near by:
