A trip to the Shorepine Bog Trail in Pacific Rim National Park Reserve did not yield the hoped-for sighting of the introduced Darlingtonia californica (seen as recently as last year, and introduced over ten years ago). I’ll excuse it on being too early in the season, given the hesitating spring. I am a bit curious as to why Parks Canada staff allow the plants to persist, given that they are non-native in many definitions of that term, but perhaps they are doing some long-term monitoring.
It was, however, an opportunity to enjoy the natural “bonsai” of the shore pines in the area. The boggy area is much smaller in extent than Burns Bog, so it is far more difficult to isolate individual plants from the background–I opted for a texture photograph of the landscape instead.
Pinus contorta has 3 or 4 varieties depending on the taxonomic reference. Variety contorta, the shore pine, is described in the Silvics of North America: “The thick-barked trees are relatively small, short-lived, and inherently branchy. Now mostly confined to marginal sites (muskegs, dunes, serpentine soils, rocky sites), this race pioneered forest succession in the Pacific Coast region at the end of the lce Age. Needles are short, rather narrow, and have more stomata per unit area than the leaves of inland races. Flowering is abundant, and female strobili tend to mature earlier than the male. The cones are reflexed and persistent. Cones usually open not long after they mature, but serotiny is increasingly common toward the interior. Seeds are small to medium-sized, and germination is slower than that of the interior races. Early height growth nearly always is faster than that of inland populations at the same latitude. Local variations include a chemically distinctive northern muskeg ecotype extending south to western Washington.”
