Observations

Contributor: Pat Kociolek - March 2011
Length Range: 10-15 µm
Width Range: 3 µm
Striae in 10 µm: Striae are not easily visible

Description

Valves are linear with straight or slightly concave margins. The apices are protracted, narrow and narrowly rounded. Fibulae are distinct and number 12-16 in 10 µm. Striae are not easily visible, being resolved in only some specimens.

EMAP Assessment

The Environmental Protection Agency (EPA) western Environmental Monitoring and Assessment Program (EMAP) study was completed during the years 2000-2004 (see citations at bottom of this page). Over 1200 streams and rivers in 12 western states (Arizona, California, Colorado, Idaho, Montana, Nevada, North Dakota, Oregon, South Dakota, Utah, Washington and Wyoming) were selected for sampling based on a stratified randomized design. This type of design insures that ecological resources are sampled in proportion to their actual geographical presence. Stratified randomized design also allows for estimates of stream length with a known confidence in several “condition classes” (good or least-disturbed, intermediately-disturbed, and poor or most-disturbed) for biotic condition, chemistry and habitat.
