Southern vancouver island has LOTS. most of greater victoria is low. but driving to mill bay (1.5hr +/- from ferry) then into shawnigan lake will take you to some more areas that are slightly higher in the hills and further from ocean spray. Old baldy mountain would be my suggestion. Easy to walk up, or drive if you have 4x4 (private land i think?, its gated). I remember LOTS of the smaller arbutus like plants that look more like wiry shrubs further in the mountains far from ocean. From shawnigan you can take the road from the village, or masons beach, and go out toward the back side of the lake. instead of turning, stay straight/right on the main road which goes into the hills. You reach Koksilah park eventually (car can drive these roads last time i went, but its not paved). When you reach Koksilah Park, its gated soon after. so park. I saw eh trees while hiking from there up to wild deer lake. Cross the bridge at Koksilah and explore, it will be all walking from there. could bring a bike and do logging roads, i saw them in open cut areas. They grow thick kind of like broom, about the same height as well. Lots of bears eat the berries, and the area has TONS of cougar and bear, so be careful. I know its not on the mainland, but if you are really searching for localities somewhat away from the ocean, i suggest these 2 for being 100% guaranteed to have trees. The new paved road from Port renfrew to Lake Cowichan (nice drive) i saw very very few from the road, but if you find them near lake cowichan it would be surely a good bet they would grow fine in your area if ocean proximity is a factor. Anyone know why exactly they like to stick to the coast? Everyone seems to "know" it, but never understood the reason why.
