Trumpeter Swan
Occurred the most disproportionately in hexagons with more than 4%
wetlands and wet shrubland. Where less wetlands and wet shrubland, it
occurred mostly in hexagons with May precipitation (hex. avg.) of 30-
35 mm. The logistic regression analysis showed weak positive or
negative association with wetlands and wet shrubland, ponderosa pine
- juniper woodland, elevation (hex. avg.), topographic variation, and
number of land cover type.
