Pollinator Abundance and Diversity Under Differing Wet Prairie Management

Pollinator species have seen recent declines in abundance, generating conservation concern as well alarm about the ecosystem services they provide. A common approach to alleviate pollinator decline is through habitat management, including restoration of degraded habitats and removal invasive species, but apparent improvement does not necessarily mean an abundance diversity. We collected pollinators colored pan traps at three sites Lacamas Prairie Natural Area, Washington: remnant wet prairie, restored area invaded by reed canary grass (Phalaris arundinacea). used model selection assess whether site trap color explained variation richness, was similar native with predicted averages 9.06 (7.15, 11.48) 9.51 (7.52, 12.03), respectively while a heavily had significantly lower 7.26 (5.69, 9.26). Site included top for richness or All measures varied color. Habitat control appear benefited local populations, evidence differences diversity weak. Further work, both characterizing response communities prairie optimizing colors monitoring this area, warranted.
