There is a bumper crop of blackberries this year in Vancouver. This has been brought about by lots of rain in June followed by hot, dry weather after, creating ideal condition.
Blackberry shrubs are found all over the lower mainland — roadsides, fence lines, stream banks, railway tracks — and they grow just about anywhere.
I bike to work on most days in summer. Along the bike route there are also a lot of blackberry shrubs. These shrubs I find along the route are largely untouched because unless you are on the route you will not know they are there.
