SO WHAT ?

 

MATERIALS:

sweep nets

bug jars

magnifying lens

insect guide book

compass

Methods:

1. We chose two sites along the Sandy Seep Trail of the Mount Elden Trail system of the Coconino National Forest near Flagstaff, Arizona. As an old burn site we used the Radio Fire of 1977, and fora new burn site the Side Fire of 1996. Both fires are classified as high intensity fires. The site map details the area of each fire.

2. At each site, we used the insect nets to collect flying insect samples along a randomly choosen path heading west. Each sample consisted of fifty sweeps, with three samples taken at each site. Note that for scientific accuracy it is important to take the samples under the same conditions at both sites, i.e. time of day, weather conditions, temperature.

3. To replicate the procedures the students would follow, we identified the insects we caught desciptivelyinstead of scientifically. We used field guides as a guideline to the insect families. We tallied the number of each type of insect caught during each sample. A list of the insect descriptions and the data chart are given in "What We Discovered".

4. For more information on this and other sampling techniques please refer to Bibliography . For lesson plan suggestions please refer to Resources.
