Hydrologic controls on the survival of Water Howellia (Howellia aquatilis) and implications of land management

Range-wide status assessment of Howellia aquatilis (water howellia) /

“…Analysis of water chemistry by Lesica (1992), and Reeves (2001) in the Swan Valley of Montana shows specific conductance readings from <30 μS/cm to 400 μS/cm with most ponds below 150 μS/cm. Measurements of pH ranged from 6.2 to 7.8 with most measurements between 6.5 and 7.5.…”
