Extra Credit Robins and Oak Trees experiment Due to their large size oak trees become shelters and nesting sites to very many wildlife species‚ so if one were to remove or decrease availability of these oak trees then one might expect the abundance of the animals that use oak trees as a home would decline as well. In this experiment‚ we will be testing whether or not the availability of oak trees in an environment will affect the distribution and abundance of robins. The hypothesis of the experiment

The data collected from the number of each type of macroinvertebrate was calculated to determine the Modified Family Biotic Index‚ percent contribution of dominant family‚ and EPT Index number for each of the three collection sites. The number of organisms and families of macroinvertebrates along with the calculated data can be seen in Table 1. Other sets of data was recorded and compared to test the stream quality at Pricket’s Creek. The water temperatures (°C) were 16.76 ± 2.32 (mean ± St. Dev
