Abstract
Quercus garryana ecosystems are threatened Mediterranean-like sites that occur in a limited range on the west coast of North America. This ecosystem has higher plant diversity and rarity than any other in British Columbia with less than 10% remaining as relicts due to habitat loss, fragmentation, and degradation. The bryophyte component remains understudied, and identification of habitat associated communities could provide a more accurate picture of ecosystem health at remaining sites. We used floristic habitat sampling and multivariate analyses to determine bryophyte diversity and community composition among three prominent mesohabitats (meadows, outcrops, Quercus garryana epiphytes) in five intact sites. We found that total species richness was highest in meadows (67), high in outcrops (63), and lowest on Quercus garryana (40) and included 11 provincially rare species. Alpha diversity and mean transformed abundance classes were significantly lower in the Quercus garryana mesohabitat versus meadows and outcrops. Multi-response permutation procedure indicated the Quercus garryana epiphytic community as statistically unique, whereas there was no significant difference between meadow and outcrop mesohabitat communities. Several species were identified as indicators for each mesohabitat type. Observations were compiled with micrographic images as a special project using the citizen science application iNaturalist. This study of Quercus garryana ecosystems from southeastern Vancouver Island, B.C., provides a preliminary mesohabitat assessment for bryophytes in this rare and threatened heterogeneous ecosystem. These baseline results can help identify priority sites for restoration based on habitats associated with bryophyte species diversity.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
