Where it has been recorded

BothSpecimensObservations

52 squares of about 28 km, each holding at least one record. A square is not a claim that the plant grows throughout it, and an unshaded square is unrecorded rather than empty. Darker squares hold more records, which follows roads and towns as much as it follows the plant. 60 herbarium specimens and 202 field observations this project may redraw. A filled dot is a pressed sheet somebody can re-examine; a hollow ring is a photograph identified by community agreement. Where the dots are dense is where people have looked, not where the plant is commonest, and empty ground is unsurveyed rather than unoccupied. How this map is made.

Which ecoregions the records fall in

Northern Continental Divide south AB: 225 records, high confidence
Aspen Parkland central AB / SK: 96 records, high confidence
Western Alberta Upland central AB: 89 records, high confidence
Fescue Grassland south AB: 21 records, high confidence
Eastern Continental Ranges central AB: 8 records, medium confidence

These are counts of records collected somewhere in the region, which is the resolution of the evidence: the map above shows where inside it. A region with 3 records is not the same claim as one with three hundred, so the count travels with the region. A region missing from this list means nobody has recorded it there, which is not the same as the plant being absent. Records within 900 m of a border count for neither side, because the border is not drawn finely enough to say which one they are on.
