Introduction

We believe that this field activity integrates several subjects in a single exercise to provide for students' successful learning.

Our primary goal for performing this evaluation was to enable us to perform similar field exercises in our respective middle/high school classes. We had a genuine concern as to which protocol would provide the most accurate, expedient, cost and time efficient method, while resulting in the minimum site disturbance . Teachers commonly experience natural limitations such as finite class periods, lack of funds, and limited access to suitable habitat. Obtaining accurate data under these circumstances is a dilemma.

Are there significant differences in the measured frequency of ground cover when evaluated by three different methods of data collection? We chose to compare a line intercept transect, a strip transect, and plot sampling in an area near Mt. Elden in Flagstaff, Arizona. The participants of this study were members of the Mapping Roads to Environmental Science on the Internet (MRESI) workshop at Northern Arizona University (NAU), Flagstaff, AZ directed by Dr. Paul Rowland, assisted by Suzan Craig. Field methods were adapted from Field and Laboratory Methods for General Ecology, by James E. Brower, Jerrold H. Zar and Carl N. von Erde.
