What do the scientists find? See the charts below. Wildlife population trends are described as a lambda value. A lambda value of 1.0 denotes a stable population. A lambda values that is less than 1.0 suggests a declining population and a value that is greater than 1.0 is increasing. All populations being studied have population estimates that average |
