The Himalayan or Armenian Blackberry [Rubus procerus/armeniacus/discolor]; large lobed, oval leaves (the ones in the picture are small - I've seen some as bid as my hand, though these are uncommon), the berries are prolific and ripen in late July into August, the primary canes can become as large as a nickel (or more) in diameter.
This is the most common and invasive blackberry and its shallow roots contribute significantly to streambank and riverbank erosion.
The Cutleaf or English Blackberry [Rubus lacianatus]; medium sized multisectioned leaves, berries not nearly as prolific but ripen earlier than Himalayan Blackberries, canes are not nearly as thick either but are a much darker maroon-ish color (like a good dark red wine).
This is the second most invasive blackberry.
The native Oregon (and Pacific NW) Blackberry [Rubus ursinus]; small to medium sized leaves that are double-toothed, moderate berry production, unsure of ripening time though it can be as early as June, canes are thin and ground trailing (normally, though they may find an upright path through other vegetation).
Native blackberry.
