LC
Sandhill Crane Grus canadensis



Justification

Justification of Red List Category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The population is inferred to number 670,000-830,000 individuals (Wetlands International 2020), which roughly equates to 450,000-550,000 mature individuals.

Trend justification
The species has been undergoing a large, significant increase at an average rate of 5% per year between 1970 and 2019 (Rosenberg et al. 2019; Partners in Flight 2020). The population in North America has increased by >600% over the past three generations (Pardieck et al. 2018). The population in Cuba is stable (Wetlands International 2020).
