STEP 2a: Observe Mearns Rock
The goal in this step is to familiarize yourself with the
Mearns Rock photo data below. Quickly look through some of the photos
and learn to navigate on this page. Don’t worry about reading
all the accompanying text for now—you will return to this page
later to do that.
The photos are of Mearns Rock and the Mearns Rock quadrats from 1990 to 2004 (click the tabs to see photos from different years). Notice that on the left side of each page is a photo of Mearns Rock in its entirety. On the right side of each page is a close-up photo of the corresponding quadrat for that year. Later, you will come back to this page to estimate the percent cover (i.e. abundance) of each organism from the quadrat photos.
But first, you will need to collect a few resources in order to record your data. to gather these resources and begin collecting your data.
When you come back to collect data, you will use the Percent Cover Chart and Color Chart in the Pop-up Window as an aid in estimating the percent cover of each organism on the quadrat you are observing. Think of the black areas in the chart as representing one of three life forms you learned about earlier in the field guide.
