Introduction to Occupancy Modeling
COURSE DESCRIPTION
Species presence/absence is a fundamental concept used in many areas of ecology (e.g., species distributions, habitat modeling, monitoring, and metapopulation studies), however imperfect detection can lead to false absences. Unaccounted for false absences can lead to misleading inferences about patterns and dynamics of species occurrence and the factors that influence them. We will learn methods for accounting for imperfect detection with species detection/non-detection data and also discuss important study design considerations. Exercises are completed using Program PRESENCE and RPresence.

PREREQUISITES
This course is for those with no, or little, experience with occupancy modeling, but more experienced users may also benefit from attending. Familiarity with regression, logistic regression, or generalized linear modeling would be advantageous (e.g., R Boot Camp, Ecological Statistics and Modeling, & Generalized Models). Suggested readings for the course:
MacKenzie, D. I., Nichols, J. D., Lachman, G. B., Droege, S., Royle, J. A., & Langtimm, C. A. (2002). Estimating site occupancy rates when detection probabilities are less than one. Ecology, 83(8):2248–2255.

Design tools
“The Occupancy Modeling course offered by CWS is great for beginners or experts working with presence/absence data. Each module is designed to reinforce different occupancy modeling concepts and provides you with tools to best analyze your presence/absence data. I really appreciated the group discussion page that showed different points of view on topics from other students taking the course. Definitely a course worth taking!”

“Darryl MacKenzie is an awesome instructor. He was able to make Occupancy Modeling both interesting and understandable. The real-world examples and discussions helped me apply the methods to my project design. Thanks for the great experience.”
