OVERALL HABITAT/POPULATION/RISK SUMMARY1: Rio Grande turkey on Black Kettle Shinnery Oak

was determined to have Low risk rating.

STATUS SUMMARY2: Current and projected status of the Rio Grande turkey on Shinnery Oak. Vulnerability to 

habitat factors are Moderate overall. Vulnerability to population factors are Moderate overall. 

RISK SUMMARY: The severity and likelihood of identified threats to Rio Grande turkey are Moderate and Low,

respectively.

Species determined to be High at-risk are further evaluated for population trends and a conclusion 

statement is stated below.

CONCLUSION: 

1 The overall habitat/population/risk score is an average of the scores assigned to these three factors during the risk assessment 

process. A score = or < 1.5 indicates the species is at risk.
