Overall, the current capture protocols and methods on Eurasian lynx do not have long lasting effects on the recoveries of the lynx from a capture event. Specifically, Eurasian lynx on average recover from a capture event within 2.0 days post capture. Age of the lynx was found to be the most influential factor on the recovery period. No statistical significance was found between capture methods, capture number, gender, age, or whether or not surgery was performed, although some differences in recovery times existed. Researchers should evaluate capture effects to not only ensure minimal human impact and continued existence of their study animals, but also to objectively refine capture methods as needed.
