1. BENTHIC MACRO-INVERTEBRATES

2. MACRO = LARGE

3. INVERTEBRATE = ANIMAL LACKING A BACKBONE

4. MACRO = LARGE INVERTEBRATE = ANIMAL LACKING A BACKBONE BENTHIC = BOTTOM DWELLING

8. STREAMS RIFFLE = RAPIDS (TURBULANCE OVER A ROCK BOTTOM)

9. STREAMS RIFFLE = RAPIDS (TURBULANCE OVER A ROCK BOTTOM) RUN =

10. STREAMS RIFFLE = RAPIDS (TURBULANCE OVER A ROCK BOTTOM) RUN = VISIBLE CURRENT (GRAVEL AND SAND)

16. COLLECTING INVERTEBRATES

18. WHAT DID YOU FIND??

19. What is Biomonitoring? Biomonitoring is the cataloging of which organisms live in a particular habitat and then, from knowledge of what conditions those organisms tolerate, determining the well being of that particular habitat.

20. What is Biomonitoring? For river systems, the biomonitoring of aquatic invertebrates, such as insects, is recognized as an important tool for determining a rivers health and, with proper background data, identifying changes in that health.

21. POLLUTION TOLERANCE

22. THE POLLUTION TOLERANCE IS… –THE AMOUNT OF POLLUTION IN A HABITAT THAT A SPECIFIC SPECIES LIVES WITH AND STILL SURVIVES AND REPRODUCE

23. EXAMPLES

24. 1 = NOT TOLERANT

25. EXAMPLES 1 = NOT TOLERANT 5 = AVERAGE TOLERANCE

26. EXAMPLES 1 = NOT TOLERANT 5 = AVERAGE TOLERANCE 10 = VERY TOLERANT

27. EXAMPLES 1 = NOT TOLERANT  GOOD!! 5 = AVERAGE TOLERANCE 10 = VERY TOLERANT  BAD!!

28. WHAT ANIMALS ARE NOT TOLERANT?

29. STONE FLY

30. WHAT ANIMALS ARE NOT TOLERANT? STONE FLY

31. WHAT ANIMALS ARE NOT TOLERANT? STONE FLY  1

32. WHAT ANIMALS ARE NOT TOLERANT? MAY FLY  2

33. WHAT ANIMALS ARE NOT TOLERANT? CRANE FLY  3

34. WHAT ANIMALS ARE NOT TOLERANT? CASED CADDIS  3

35. WHAT ANIMALS ARE MODERATELY TOLERANT? FREE CADDIS  4

36. WHAT ANIMALS ARE MODERATELY TOLERANT? BEETLES  4

37. WHAT ANIMALS ARE MODERATELY TOLERANT? CRAYFISH  6

38. WHAT ANIMALS ARE MODERATELY TOLERANT? THREADWORM  6

39. WHAT ANIMALS ARE VERY TOLERANT? BLOODWORM  8

40. WHAT ANIMALS ARE VERY TOLERANT? LEACH  10

41. If you go to a portion of the river and the main organisms collected are leeches, bloodworms, and certain types of snails, the water quality in that area is very poor. If, on the other hand you collect a lot of mayfly larvae, stonefly larvae, and caddisfly larvae, these are usually indicators of very good water quality.
