In this video Hannah Specht and Henry Reich explain how their new conditional occupancy survey design works. Occupancy surveys are widely used in ecology to study wildlife and plant habitat use. Occupancy models account for imperfect detection probability. However, occupancy probability estimates for rare species tend to be biased because we’re unlikely to observe the animals at all and as a result, the data aren’t very informative. The authors developed a new “Conditional” occupancy survey design (just published in Methods in Ecology and Evolution) to improve occupancy estimates for rare species and compare it to standard and removal occupancy study designs.
