4
Healthy? Threatened? Endangered? Counting has legal consequences! Please get out your wildlife management notes.
5
Random Sampling activity – (the beans) Share your * answers! #3 – Asymptotic point = more PRECISION #7 – How could we have improved accuracy? Does any of this apply to our lab work comparing the managed and unmanaged prairie areas?
6
Why count population size accurately? Census vs. Random sampling. Standardized procedure reduces bias Improving accuracy: More samples Strict standards for asymptotic point Tailor data collection to organism’s life history ROBUST DATA! Accuracy is important – legal protection can limit individual land use/decisions

Quadrant Sampling in Wolf Prairie – design flaws?
