Abstract

In semiarid rangelands, a variety of permanently wet habitats can be classified within the general category of springs. Emergence traps were used to collect aquatic insects from helocrene habitats in the Bridge Creek watershed in C Oregon. Water chemistry analyses showed high conductivity, pH, and cation concentration values at all sites. Nematocerous Diptera typically comprised greater than 90% of the aquatic insects in emergence traps. Other aquatic orders were uncommon and low in species richness and abundance. Plecoptera were common at only one site, while the damselfly, Argia vivida occurred at all sample sites. -from Authors
