Our trip to Cliff Stephens Park turned out to be another nice sunny day without rain. We had 5 different groups with 5 sections of different things we had to do. There were bags with tools set in each location. In one location we had quadrats that we placed every 3 meters. We did that 10 times on a 30 meter transect line. Examining the quadrats we had to write how much % of grass, litter, and other things we saw. It took place right in the sun and got very hot. Then we used a small shovel to dig for dirt and poured water on it to see the soil type and if it could make a ribbon. Luckily the next few locations we went to were in the shade. We used a densiometer to measure the canopy cover marking a + if we saw cover and - if we didn't. There was D-tape to measure trees at breast hide to see how large the tree was compared to the others. The Cruz-all measured the basal area of the tree when we held it back by our necks. For one of the locations we sat at the benches and did a mark and recapture experiment with beans. We made a defining mark like an x which was used to see the ones we captured. Then we put them in a bag and without looking grabbed a handful of beans from the bag. Using a formula we were able to determine the population size. We also tested the pH of the water, salinity (salt), turbidity, and the temperature in our last section by the water. For most of the sections we were able to stay in the shade because the park had a lot of trees. Only 1 or 2 of the sections had very little cover and we had to be stuck out in the sun. There were a lot of people playing disc golf. There were a lot of tools and things we had to test and measure which did get overwhelming and hard to remember. Though at least from actually doing all of this it gave a general idea of the processes and tools needed to gather this kind of data.
