Directions Consult the macroinvertebrate monitoring manuals for sampling guidelines
- Separate the macroinvertebrates into the different taxa groupings listed in the table below
- Note with taxa are present and their abundance code based on the number of individuals present in your sample. Enter these codes in the boxes below for each taxa.
R (rare) = 1-9, C (common) = 10-99, and D (dominant) = 100 individuals or greater
Stream habitat will be evaluated looking both upstream and downstream, and includes: channel bottom materials, streamside vegetation, slope, and other channel characteristics.
You may choose a value between 1-10 for each parameter. Note questions 8-10 ask you to evaluate each bank separately.
All measurements should be taken during baseflow conditions. Stream reach is defined as 12 times stream width, bankfull to bankfull.
Rocky bottom steams need to evaluate embeddedness whereas muddy bottom streams need to evaluate channel sinuosity.
What types of submerged materials are on the channel bottom?
Little or no stable habitat cover available for colonization by macroinvertebrates and fish: submerged roots, woody and vegetative debris, cobbles, leaf packs and undercut banks; habitat may move during high flows.
Adequate stable habitat cover for colonization by macroinvertebrates and fish: submerged roots, woody and vegetative debris, cobbles, leaf packs and undercut banks
Abundant stable habitat cover for colonization by macroinvertebrates and fish: submerged roots, woody and vegetative debris, cobbles, leaf packs and undercut banks.
Riffle/Run/Pool Presence or Absence
Are riffles, runs, and pools present as habitat in your stream reach?
Only one (1) habitat type present and dominant.
Two (2) habitat types are present.
Yes, all three (3) habitat types (riffle, run, pool) are present and frequent.
Are sandbars and islands present?
Heavy deposits of usually fine sediment; channel affected by extensive deposition. Point bars are bare.
Some new bar formation of the channel bottom with new deposition in pools. Some increase in point bar formation.
Little or no enlargement of vegetated islands or point bars.
How much algae and aquatic plant growth exists in the stream?
Pea green, gray, or brown water in whole reach; dense stands of plants clog stream; severe algal blooms create thick algal mats in stream.
Fairly clear to slightly greenish water in whole reach; some to abundance of lush green plants; moderate to abundant algae growth
Clear water in whole reach; diverse aquatic plant community - low quantity of plants; little algae growth
Has the stream channel been altered by humans?
Most of stream reach channelized and/ or many alterations present such as dredging, agriculture, concrete banks or construction activities. Little sign of recovery.
Some evidence of channelization and/ or alterations such as dredging, agriculture, concrete banks or construction activities. Or full recovery from any alteration.
No evidence of channelization (straightening) or alterations such as dredging, agriculture, concrete banks or construction activities.
Are fine sediments being deposited in riffle/run area?
Gravel and cobble are completely embedded in riffle area.
Gravel and cobble are partially embedded in riffle area.
Gravel and cobble are slightly embedded in riffle area.
How stable are the stream banks?
Bank unstable; many eroded and scoured areas with undercutting; bank failure present; steep banks. Little over hanging vegetation present.
Bank moderately stable; evidence of small areas of erosion, undercutting and scouring, or bank failure present. Moderate amounts of overhanging vegetation present.
Bank stable; erosion, scouring, undercutting or bank failure absent or minimal. Vegetation overhanging the stream is abundant.
Are stream banks covered & shaded by a variety of vegetation?
Few streambank surfaces covered and shaded by vegetation. Little variety of vegetation. Streambank dominated by one type of vegetation (trees, shrubs, flowering plants and grasses).
Some streambank surfaces covered and shaded by some variety of vegetation (trees, shrubs, flowering plants and grasses).
Most streambank surfaces covered and shaded by a large variety of vegetation (trees, shrubs, flowering plants and grasses).
Riparian Vegetative Zone Width
What is the amount of buffer available?
Little or no buffer present; vegetation extends less than one channel width on each side. Human activities substantially impact buffer zone.
Some buffer present; some variety of vegetation extends one to two channel widths on each side. Human activities have impacted buffer zone.
Buffer present; a large variety of vegetation extends at least three channel widths on each side.
