Awaken Treants (Su) A great wyrm dragon can call on the forest itself to aid it, animating a number of trees to serve as treants to protect it. These treants can be called from any Huge or larger living tree. A green dragon can create a single treant as a standard action, up to a total of 4 treants per day. These treants remain animated for up to 1 hour, at which time they revert to being ordinary trees.

Camouflage (Ex) An old or older green dragon can use Stealth to hide in any sort of natural terrain, even if the terrain does not grant cover or concealment.

Miasma (Su) An ancient or older green dragon can use its breath weapon to create a cloud of acid as a standard action that deals damage to any creature inside it. The cloud moves with the dragon and has a radius of 20 feet. When it's created, anyone inside this area takes an amount of damage equal to half the dragon's breath weapon, with a Reflex save for half damage. The number of damage dice rolled is halved each round until the result would be less than 1d6. Any creature that starts its turn inside the cloud takes damage, but can make a Reflex save for half. A strong wind, such as that created by a gust of wind, disperses the cloud in 1 round. Spell-Like Abilities (Sp) A green dragon gains the following spell-like abilities, usable at will upon reaching the listed age category. Young-entangle; Juvenile-charm person; Adult-suggestion; Old-plant growth; Ancient-dominate person; Great wyrm-command plants.

Trackless Step (Ex) An adult or older green dragon does not leave a trail in natural surroundings and cannot be tracked. A green dragon can choose to leave a trail, if it so desires.

Water Breathing (Ex) A green dragon can breathe underwater indefinitely and can freely use its breath weapon, spells, and other abilities while submerged.
