Cinnamomum cassia has a sweeter flavor than Indonesian cassia, similar to Saigon cinnamon, but with lower oil content. Cassia bark (both powdered and in whole, or "stick" form) is used as a flavoring agent for confectionery, desserts, pastries, and meat; it is specified in many curry recipes, where Ceylon cinnamon is less suitable.

Cassia sticks can be distinguished from Ceylon cinnamon sticks in this manner: Ceylon cinnamon sticks have many thin layers
Cassia crossbill Red Squirrels as their beak is adapted for a specific type of pine cone. This has led to a coevolutionary arms race with the lodgepole pine, which explains why they are confined in such a small area. Other Red Crossbill call types, typically call type 2 & 5, are also found in these areas, but seldomly breed here due to being poorly adapted to the pine cone structure. Due to their restricted range and habitat, there is a cause for concern for this species survival. The Cassia crossbill ("Loxia sinesciuris") was first described in 2009 as the South Hills crossbill,
