Horn und Tusk 
The tusk scale was created in order to provide an easy to understand measure of how an elepahnt popualtion is doing. Each tusk rating is provided below with a description of its meaning for elephant population health.
The normal tusk represents a population that is overall ok. The number of elephants is high and general threats are not extreme. This population is still at risk, but is growing or stable.
The cracked tusk represents elephants at risk. These elephants are facing challenges and the population number is approaching crisis levels. There is still time to save these populations.
The blood tusk represents elephant popualtions in critical condition. These elepahnts are at risk of being lost forever as a result of serious threats such as heavy poaching, catastrophic land loss, inadeqaute conservation initiatives, and war.
The shattered tusk represents elephant populations that have been confirmed or are most likely lost. No elephants can be found here anymore.
