I like to bring gifts of simple food or tea to the woods and leave themin front of a tree or on a stone. I know that animals will come and eat it and it will feed the ground. They can also be dedicated to a god or goddess.
i would say plant and tend to a garden, plant seeds, collect pollution/trash from side of road or trail if you run across it, birdhouses, leave cracked corn out for wildlife etc.
