Pin Oak
Calculated with the same rules as North Carolina, using Tennessee host-range and conservation-rank inputs. Native-status evidence is shown separately.

Insect resources, birds and habitat
| Caterpillars | 452 recorded species on the genus Host genera of native Lepidoptera recorded in Tennessee; host association and range overlap, not confirmed local feeding. |
| Bees | 19 recorded species on the genus Southeastern North America |
| Specialist bees | 0 recorded species on the genus Eastern North America |
| Birds | 23 recorded species on the genus North America |
| Structure | Tree |
Baseline 88; additional insect credit +0. Rarity adjustment -5 using the NC rule (unranked: −5; final score floor: 5). Missing records do not establish zero ecological use.
Native to Tennessee (state-specific source). Tennessee yard-fit calculations are not available yet.
Also available: North Carolina assessment. Both assessments use the same scoring rules with the evidence shown for each state.

County occurrence is not proof of native range or yard suitability. A missing record does not establish absence.

Growing conditions
Full sun; moderately wet to medium moisture level; prefers rich organic soils but does well in silty clay loams and hard compact clay soils; moderately acid to slightly acid pH and does not tolerate high neutral pH where it is very subject to iron chlorosis (yellowing of the leaves where veins remain green).

Native-status evidence
Combined TN–KY atlas flag: Y. A regional flag alone does not settle Tennessee native status.

Combined-source assessment
Native to Tennessee (state-specific source)
A TN-specific UT native-guide page or an exact entry in the Tennessee rare-plant list supports a direct source claim. Otherwise, TN occurrence plus an atlas native flag and exact-name native evidence from NC flora or USDA L48 supports a provisional state inference. No one regional claim or occurrence alone establishes TN nativity; NC and L48 claims retain their actual scopes.
UT Tennessee Smart Yards native-plant guide: native (TN). Native Region: Scattered counties statewide excluding the Blue Ridge Province
NC vascular flora: native (NC).
USDA PLANTS: native (L48). CAN:N L48:N
TN–KY Plant Atlas: native (TN–KY).
