Macroinvertibrates

How to catch Macroinvertibrates

Tools:

Net
Squirt Bottle
Scrubber
Tray
Sorting Tray
Eye Dropper
Spoon
1. Choose one person for each job.

2. Have the net people enter the stream in a shallow area down stream of a riffle. Open the net to its full extent and hold it like you are shoveling the water. Make sure the bottom of the net is on the bottom of the creek,

3. Next have the rock scrubber enter the creek upstream of the net person preferably in a riffle area. The rock scrubber needs to flip over rocks and scrub them, under the water, to free the Macroinvertibrates from the rocks. They may also use hands and feet to stir up the creek.

4. Once step three is complete the net people must carefully scoop the net up out of the water. As they do this they are being careful not to dump the Macroinvertibrates out of the net.

5. The net people and scrubber exit the stream. Holding the net vertically over the tray the squirt bottle person sprays the net to dislodge any critters that are on the net.

6. Now the sorters will use the eye dropper and spoon to catch the different critters found in the tray and place them in the sorting tray.

7. Finally your group needs to record how many Macroinvertibrates you have found.

PH Test

Establishing a Photo Point Procedure

Photo Point Procedure

Objective:
A photo point is done in order to observe the change which will occur in a certain location over a point of time. This procedure will show how to establish a photo point

Materials

Compass
Tape
Meter Stick
GPS

1. Locate what you would like to observe. (Point A)
2. Locate a point in which to take the picture from (Point B)
3. Once (Point B) has been created use the GPS to discover its exact location. Write the longitude and latitude on the photo point data sheet
4. Measure the distance between (point A) and (point B). Record this measurement on the photo point data sheet.
5. Stand on (point B). Use a compass to locate the directional degrees( point B) is located from (point A). Write degrees on photo point data sheet
6. Draw a map which will allow you to locate this point in the future

Photo Point Procedure at an Established Photo Point

Photo Point Procedure

Objective:
A photo point is done in order to observe the change which will occur in a certain location over a point of time. This procedure will show how to take a picture at an established photo point.

Materials

Compass
Tape
Meter Stick
GPS

1. Locate. (Point A)The point to take the picture using your GPS and the Lat and Long information found on the photo point print out
2. Have one person stand on (Point A) and use the compass to find the direction of (point B). Degrees are found under compass heading.
3. Once direction is determined have one person take the measuring tape and measure from (Point B) until you reach the written distance between the two points.
4. Place the camera on the yard stick facing the correct compass direction towards (point B)
5. Take the picture.
6. Check picture and put supplies away.
7. Be sure photo point paper has been completed
