First, there are 2 kinds if huckleberries, reds and blues. They both grow in similar country, often next to eachother. Anywhere its open with the perfect amount of sunlight, some areas have a lot of berries, some don't. Higher elevations seems to hold more blue huckleberries.
Blackberries there are also 2 different kinds, the "wild" kind, which grow all over especially in salal and are very small. The other thorny kind mostly seem to grow in lower elevations and near roads where the dirt has been dug up.
I'm not sure salmon berries are edible, at least not the ones I call salmon berries. They grow anywhere its somewhat damp and higher elevations say 1-2,000ft
I've never seen wild blueberries, but I have heard of them.
There are wild strawberries here in higher elevations in openings like clearcuts and overgrown roads. They are very small I doubt the bears target them.
So far it seems to me the blue huckleberries are the bears favorite food in the areas I hunt, between mid august through mid October. I thought most of the berries were probably gone by now but yesterday I saw 2 nice fresh piles of bear poo that were plum full of blue hucks.
