pine ID's again

I don't seem to be able to identify conifers yet.
Ok, so I've got 1 picture of what I assume is sylvestris and
then 3 pictures of another pine.
Thank you for your help,
Terri

Here is a link that might be useful: pictures of 2 pine trees

| #1 is as you guessed Scots Pine Pinus sylvestris #2 is Lodgepole Pine Pinus contorta, most probably Shore Pine Pinus contorta subsp. contorta What location? That would help determine which subspecies. Resin |

Thank you,
Snohomish county, western Washington.
I'm trying to get these trees to produce pine nuts for
wildlife.
I don't have any other sylvestris yet.
But I do have 2 contorta.
They are upwind from this tree about 100'
One of them is small, would I need to move that one
closer to the middle of the two trees for pollination?
Thank you,
Terri |

I read that sylvestris will hybridize with mugo.
But I don't find anything in the cones.
They are next to each other.
Maybe they just don't pollinate each other very well
and I need to get another sylvestris?
If there were good pollination shouldn't at least half the cones contain seed?
Thanks,
Terri |

| "One of them is small, would I need to move that one closer to the middle of the two trees for pollination? " No, pollen can blow a lot further than that. "I read that sylvestris will hybridize with mugo" They can, but they don't do so very easily at all - the hybrid is very rare. Resin |

| The shore pine shown has the lush grassy looking foliage etc. of the outer coastal type. Local native specimens in peat bogs and riverside swamps east of Puget Sound produce smaller, less generous leaves on more restrained- and even darker-looking crowns with dark bark and small cones that open on the trees. I have been among comparatively tall examples on the edge of the game department property on Ebey Island, near Everett that had winter high water marks above my head - these must regularly spend long periods under water without dying. We had to canoe the river etc. to get to this location, I would suggest instead looking for other stands elsewhere in view of Hewitt Avenue. There are places were some grow near paved roads, such as at Pinehurst (a neighborhood name on the map more than an actual town), which I remember as being east of Lowell, again down in the wetlands. Another place in the vicinity is the remains of the peat bogs east of Pacific Topsoils, do not know what the public access situation might be - I have never attempted to get in there, but the pines are quite visible from the arterial. If there is any part of the property where access is possible these are also likely to have open cones, which in season would be expected to be releasing seeds - the many times I have seen this type here the cones appear to be completely non-serotinus (not waiting for fire to open). There were government-generated web pages up at one time that stated that these Puget Trough wetland pines were a different race from the outer coastal, an Alaskan origin form that came down from there and persisted to the present in cold, damp pockets like bogs. After reading this one time I was never able to find the same discussion again, or get any other hits from other places on the internet expressing the same idea. |

| "The shore pine shown has the lush grassy looking foliage etc. of the outer coastal type" That was what I thought too; my caution "most probably" was in the lack of location info . . . if it had turned out to be in Minnesota or something, then it couldn't have been that ;-) "There were government-generated web pages up at one time that stated that these Puget Trough wetland pines were a different race from the outer coastal, an Alaskan origin form that came down from there and persisted to the present in cold, damp pockets like bogs" Not come across that before, but there is some literature that points out that the pines growing on Lulu Island and other islands in the Fraser River delta in Vancouver are interior subsp. latifolia (not coastal subsp. contorta as one would expect), presumed to have resulted from seeds washed downriver from far inland.

| Here in western WA there is some blending of characters in some wild stands, those around Shelton for instance growing in sometimes dense stands on coarse-looking soils and having a bit more of a resemblance in their branching etc. to lodgepole pines than usual for locally native shore pines. Similar partly intermediate ones are also seen in local cultivation, although there are many others that clearly belong to either the maritime or the intermountain types. The latter often have eriophyid mite damage here that the westside origin trees do not. |

| "The latter often have eriophyid mite damage" What are the symptoms, please? Resin |

| Bright yellow needles or sections of needles are the most conspicuous feature. |
