See more details about dealing with  Forest Titan in its respective page.

The Forest Titan Arena is a generated arena within the UnderForest for fighting the boss of the DLC: Extinction, Forest Titan. Upon Activation of the terminal within Forest Cave, all creatures and survivors within the terminal are warped back to the arena within the map, while the  Forest Titan is bring formed on the arena and begins to attack the moment it is fully materialized.

As with the other three titans of extinction there is a 6 hour timer between summoning another Forest Titan, the timer begins immediately as soon as the Forest Titan is summoned. If the Forest Titan is still alive and tamed, the timer will still countdown, but no other Forest Titan can be summoned even after the cooldown ends until the existing one dies.
