A big tract of land
One path maker
4 cups of moonlight
A mile long lake
One very tall, invisible pole.
Wind in assorted bursts
167,220 small trees
10,200 truckloads of old decaying leaves, bark and twigs.
A couple thousand little crawly creatures
Large assortment of bugs, bees, spiders, snakes and insects.
Level off the land and dispose of anything that could be construed as garbage. Insert lake. Plant trees with perfect randomness throughout the land. Distribute decaying matter under and around the trees. While casually walking through the nearly finished assemblage, drag the path maker behind you. Walk back on the pathway you just created and intermittently allow some creepy crawly things and snakes to escape. Start the wind machine and set it to random. Fasten the moon to one end of the pole and stick the other end into the ground. Allow the birds to take flight and find their new homes. Wait a couple hundred years. Then, go visit regularly.
