Monitoring the relative abundance of bird and mammal species at Walker Bay

The relative abundance of species is recorded as the number of individuals seen per hour spent in the field per observer. Each observer record daily the animal species encountered in the field and the number of individuals observed. To correct for any potential biases the activities and mode of transportation of observers is also taken into account.

物种相对丰度以每位观察者每小时野外调查时长内所见的个体数量进行记录。每位观察者每日均需记录其野外偶遇的动物物种及观测到的个体数量。为校正潜在的观测偏差，观察者的野外活动方式与交通模式也会被纳入考量。
