My blueberry bushes love growing among my White pines.
Both blueberries (Vaccinium corymbosum) and pine (Pinus spp.) like acidic soil, and both thrive in U.S. Department of Agriculture plant hardiness zones 7 though 10, making them ideal planting partners. The berry plants' shallow roots won't bother the pine, and both will enjoy regular irrigation.
Interesting, I've seen manzanita and oaks, some birch, but no fruit trees, no berries in pine forests, in North Carolina I've seen entire swaths of only pines.
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.
