Continuation of Table of Seed-producing conifers.
Sp. | Location | Number of Cores | Number of cones on ground | Estimated Number of Cones on tree | Comments
P. ponderosa | 21m. 207° E1 | 54 | 12 | 27 | 6 ground cones were green; they were left where they were. 3 were half buried.
P. lambertiana | 15m. 242° E1 | 1 | 23 | 48 | The core had a few scales left and was complete. None of the cones were green. 20 +
P. ponderosa | 15m. 722° F1 | 60 | 9 | 40 | 2 cones chewed by S. griseus; I kept 1.
* P. ponderosa | 6m. 348° G1 | 177 | 10 | 27 | 4 cones were green and were left. ½ of this twin tree had been cut.
P. lambertiana | 17m. 157° F1 | 7 | 16 | 10 | 7 cones were green and left.
P. ponderosa | 24m. 21° HØ | 34 | 0 | 15 | Twin tree. 7 of the ground cones were green - left there.
P. lambertiana | 11m. 348° G1 | 4 | 4 | 30 | 3 cones were green - left there.
P. ponderosa | 24m. 17° HØ | 36 | 0 | 0 |
P. ponderosa | 25m. 9° HØ | | | 2 |
P. ponderosa | 31m. 358° HØ | 13 | 0 | 0 |
P. lambertiana | 29m. 352° HØ | 1 | 3 | 0 | 1 of the ground cones was green - it was half eaten. 2 + complete.
P. ponderosa | 12m. 273° G3 | 19 | 1 | 10 | the ground cone was brown, closed. All cores were 5-7 cm. - I only partially chewed.
P. ponderosa | 9m. 282° G3 | | | 0 | 15 of the 18 ground cones were green, left half buried.
P. ponderosa | 16m. 56° A2 | 163 | 18 | 75 | 6 cones on tree were brown, closed.
* P. lambertiana | 9m. 81° A2 | 37 | 18 | 60 | 3 half-eaten cones were left as were 3 mostly eaten cores left as were 16 of ground cones! were small, brown, closed.
P. ponderosa | 3m. 175° D3 | 35 | 1 | 30 |
P. lambertiana | 13m. 332° G2 | 24 | 17 | 25 | 6 cores only partially eaten.
P. ponderosa | 10m. 54° E3 | 87 | 0 | 15 | 5 cores only partially eaten. 19 uncounted cores were added.
* P. ponderosa | 6m. 348° G1 | 20 | not counted | 45 | note higher cone estimate.
P. ponderosa | 8m. 349° H2 | 16 | 0 | 2 | cores mostly small.
* These are the same tree.
