Thin section abundance estimator
Web5.1.1 HAYNE ESTIMATOR . This estimator was developed by Hayne (1949) to estimate densities of birds like grouse that flush as an observer comes within a certain radius. The basic assumption of this estimator is that there is a fixed flushing distance . r. such that if an observer comes closer than . r. units to the animal, it flushes and is ... http://nationalpetrographic.com/thin-section-microscopy-a-comprehensive-guide.html
