Abstract
Every five years, the Fish and Wildlife Division of Alberta Sustainable Resource Development reviews the general status of wildlife species in Alberta.These overviews, which have been conducted in 1991 ( The Status of Alberta Wildlife ), 1996 ( The Status of Alberta Wildlife) and 2000 ( The General Status of Alberta Wild Species 2000), assign individual species "ranks" that reflect the perceived level of risk to populations that occur in the province.Such designations are determined from extensive consultations with professional and amateur biologists, and from a variety of readily available sources of population data.A key objective of these reviews is to identify species that may be considered for more detailed status determinations.The Alberta Wildlife Status Report Series is an extension of the general status exercise, and provides comprehensive current summaries of the biological status of selected wildlife species in Alberta.Priority is given to species that are At Risk or May Be At Risk in the province, that are of uncertain status ( Undetermined ), or that are considered to be at risk at a national level by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC).Reports in this series are published and distributed by the Alberta Conservation Association and the Fish and Wildlife Division of Alberta Sustainable Resource Development.They are intended to provide detailed and up-to-date information that will be useful to resource professionals for managing populations of species and their habitats in the province.The reports are also designed to provide current information that will assist Alberta's Endangered Species Conservation Committee in identifying species that may be formally designated as Endangered or Threatened under Alberta's Wildlife Act.To achieve these goals, the reports have been authored and/or reviewed by individuals with unique local expertise in the biology and management of each species. in EXECUTIVE SUMMARYPorsild's bryum {Bryum porsildii ) is a nationally and globally rare, rock-dwelling moss that forms brilliant, rich green cushions on wet, generally unstable calcareous rock.It was first documented in Alberta in 1 828 by botanist-explorer Thomas Drummond at its type locality (the site from which the specimen used to first describe the species was collected) in Jasper National Park.Porsild's bryum was next found in Alberta over a century later in 1 966, and eight localities have been documented to date.Although the original site has not been relocated, all other known Alberta populations (one in Evan-Thomas Provincial Recreation Area, four in and around Whitehorse Wildland Park, and two in Willmore Wilderness area) are extant.Canada's largest documented provincial population of Porsild's bryum, both in terms of extent of occurrence and area occupied, is found in Alberta, where two populations are known in Willmore Wilderness, four populations are known from the Whitehorse Creek area, near Cadomin, and one population is known from Kananaskis Country.Additional Canadian occurrences are documented in Nunavut, British Columbia and Newfoundland.Globally, the species also occurs in the United States (Alaska, Montana, Wyoming, Colorado, Michigan), and around the northern hemisphere in Siberia, Kazakhstan and central Asia.Although Porsild's bryum occurs across a wide area, it is disjunct and highly localized throughout its range.Although the presence of some Alberta populations of Porsild's bryum has proven stable for up to 38 years, natural disturbances characteristic of the species' preferred habitat can lead to frequent, often broad fluctuations in local abundance.Natural frost disturbance recently reduced what was Canada's largest population (in Newfoundland), from hundreds of colonies to just nine.Research has shown that Porsild's bryum is at least partly physiologically limited to its extremely specialized habitat type.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
