HOMEWORK: USING THE MEASURES OF DENSITY, DOMINANCE AND FREQUENCY TO MAKE INFERENCES ABOUT A SPECIES – (34 PTS) Name _________________________ Lab section 11 or 12 ___ Score ___________ The data in Table 8-10 represents data collected from three different species at two sites. Compute the basal area per trunk and per tree (6 pts). Table 8-1: Total basal area (m 2 ) per for three species at three sites with the area of each site=0.04 ha.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
