Meanwhile …. Here in Canada and USA ….
All along Lake Superior, Lake Huron, Lake Michigan and Lake Ontario …. the White pine and blueberries grow side by side.
Wherever the pine needles blow ….
So all along the sunny meadows next to the Pine trees is where you will find the best blueberries….
It’s also where you will find the Black bears.
Anything else?

Not really in the forest at all, surrounded by pines. More like on the periphery. Probably because the sun.
Here on our beach on Lake Superior the best patch of wild blue berries are growing directly under a stand of Pine Trees.
Its probably the combination of lots of moisture, good mulch, plenty of sun.
A stand isn't a forest though, like the forest you posted.
