What necessary element, besides vegetation, must be continuously available for wood bison survival?

Answer

A reliable water source

While the discussion focuses heavily on their vegetative diet, survival for the wood bison is contingent upon hydration as well. The text explicitly states that the presence of water is a continuous, non-negotiable requirement for their sustenance. They cannot endure survival for extended periods without consistent access to a reliable water source, indicating that water availability is as essential as their primary forage supply.
