Welcome back! Read the board and review for quiz on laws!
Endangered Species Laws
Lacey Act
Endangered Species Act
Convention on International Trade in Endangered Species
Be ready to compare/contrast
I will answer only two questions from the class.
OK! Please put your natural
selection reading outline on your
desk for a stamp during the quiz!
Healthy?Threatened? Endangered?
Counting has legal consequences!
Please get out your wildlife management notes.
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?
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?
Transect sampling
Tag and Recapture is a TYPE of random sampling
-population size
-identify critical habitat
-identify migratory pathways
-monitor population health
Bird Banding
Contact info, ID number
Westside at Guadalupe State Park – Spring 2014 Bird Banding
Permanent tracking devices
PIT tagging
Tag and Recapture
OK to recapture same individual.
Formula accounts for this.
Why is it important for wildlife managers to determine population size accurately?
Assessing population size
Census
Counts each individual organism
