Pine tree guild

I have a group of black pine in the northwest corner of my yard that I planted ten years ago for a windbreak. They are too close together for much to grow in between, but musk strawberries are really thriving around the edges. I cut one pine to improve visisbility while backing out of the driveway and found a nice surprise, two seedling black raspberries, around a year old, I'd guess. They couldn't have had much light, so probably stunted. I assume the seeds passed through a bird since my raspberry planting is 30 yards away and on the other side of the house. I've had them about 12 years. I've never noticed a seedling before. Maybe it's not that unusual? It'll be interesting to see if they're much different than the parents.

Mark Shepard in his book "Restoration Agriculture" and in his forest ecology course talks a lot about plant communities including those for pines. Mark focuses mostly on pines that produce nuts but not only. I do not know how it is for Nevada, but for a colder regions I'm interested in the plant community that goes along with pines was:
- Pines
- Crab apple
- Siberiam Pea Shrub
- Blackberries
- Raspberries
- Mullberry
- Nanking Cherry
- Serviceberries
- Rose hips
- Haskaps
- Lingonberry
- Crowberry
- Cranberry

blueberries, huckleberries, kinnikinnik, boxwood, prince's pine, usnea, alders,  

I went with black landscape morels in the middle, musk strawberries and honey berries around the edges. I need something else that's only around 18" to put in the strawberries. It has to be short to not block the view of the street when I'm backing out.
