Howls Speaker of the trees ritual

I can choose a deep forest and cast awaken on it. That area of summoned deep forest becomes a Treant that gains 10hp per summoned patch. 

Eco Domain: summoning creatures while in the forest doesn’t require concentration but does require a round of concentration to maintain control of the creature. Once control is broken you can use an action to repossess the creature. 

Stone Soil Roots: the moving forest has advantages against spell saves. 

Friends of the Forest: you can store conjured creatures into the boundaries of an awakened forest. You are able to use your action, bonus action, and reaction to bring forth conjured creatures within the forest.
