Abstract

55 Veratrum tenuipetalum 54 Calamagrostis canadensis 54 Carex utriculata 52 Phleum commutatum 51 Eleocharis quinqueflora 49 Swertia perennis 49 Eriophorum angustifolium 48 Senecio triangularis 46 Carex nova 42 Conioselinum scopulorum 41 Epilobium hornemannii 39 Carex saxatilis 38 Bistorta bistortoides 36 Carex illota 33 Veronica nutans 32 The most frequent genus, Carex, was represented by 39 species.The top six families encountered were: Family Number of Genera Cyperaceae 39 Asteraceae 29 Poaceae 19 Scrophulariaceae 12 Juncaceae 9 Rosaceae 8 Two discoveries were especially noteworthy: Utricularia intermedia was found at three fens near Lizard Head, numbers D101, 102 and 127.This species is new to Colorado, and will be tracked as a state rare (S1) species by CNHP.Drosera anglica was found by Forest Service personnel at Fen C0919 near Purgatory.This is the first occurrence of this species documented in Colorado.Both of these carnivorous plants have a broad distribution but are confined to very specific habitats.Utricularia intermedia occurs throughout Canada and the western and northern US.It is ranked S1 (critically imperiled) in Montana, Wyoming and Utah.Drosera anglica is known from Canada, Alaska and several northern states, including Wyoming, Montana and California, where it is ranked S2 (imperiled).Eleven new element occurrence records were submitted to CNHP for inclusion in the data system.They were:Carex limosa update Andrews Lake area, fen C0254 Carex viridula update Andrews Lake area, fen C0254 Carex limosa, Molas Pass, fen C0261 Woodsia neomexicana, Vallecito Reservoir, (on the way to fens) Eriophorum altaicum, Grindstone Lake, fen D002 (update, not found in 2006, present in 2001) Utricularia minor, Grindstone Lake area, fen D017 Utricularia minor, Grindstone Lake area, fen D025 Eriophorum altaicum, Highline Trail, fen C0878 Drosera anglica, Purgatory, fen C0919 Utricularia intermedia, Lizard Head area, fens D101, 102, 127 Carex buxbaumii herbaceous vegetation, Andrews Lake area, fen C0252 PC-Ord Indicator Species Analysis was used to calculate an importance value and associated p-value (Monte Carlo test) for each species in 89 of the sampled fens (those with recorded elevation).These values were used to identify the most important species that characterized four elevational classes (11,000 -11,400 [36 fens]; 10,750 -11,099 [36 fens]; 10,394 -10,749 [11 fens] and below 10,393 [6 fens]).Indicator values were calculated by combining relative abundance (proportional abundance of a particular species in a particular group relative to the abundance of that species in all groups) and relative frequency (proportional frequency of the species in each group) following the method of Dufrene and Legendre (1997).Indicator species analysis revealed some overlap in species composition and importance within higher elevation fens: Deschampsia cespitosa, Psychrophila leptosepala, Clementsia rhodantha, and Pedicularis groenlandica, (Table 1 a, b, and c).Indicator species of fens over 11,000also included Podagrostis thurberiana, Carex illota, and Carex nova (Table 1a).Fens at 10,750 -11,099 elevation had just one unique indicator, Salix planifolia (Table 1b).Fens at 10,394 -10,749 elevation also had just one unique indicator species, Carex microptera (Table 1c).Fens below 10,393 elevation had many unique indicators including the exotic Cirsium arvense (Table 1d).Table 1.Indicator species analysis for each of four elevation ranges.Species IV p-value a) Fens at 11,000-11,400 elevation Pedicularis groenlandica 0.001 Podagrostis thurberiana 0.006 Carex illota 0.026 Deschampsia cespitosa 0.002 Carex nova 0.04 Psychrophila leptosepala 0.008 Clementsia rhodantha 0.013 b) Fens at 10,750 -11,099 elevation Salix planifolia 0.039 Clementsia rhodantha 0.013 Psychrophila leptosepala 0.008 Pedicularis groenlandica 0.001

Full frame distilled prediction

Teacher imitation

Not 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.
