Tree Father Birch

Tree Father Birch is the "leader" of the Treeminders in the Oasis. He is the husband of Leaf Mother Laurel and the father of Sapling Yew. He greets you upon nearing the entrance. After leading you to the center of the grove. Birch will enter conversation which will begin the Oasis (quest). Players can use Speech to learn of the (believed) nature of Harold and also use the Animal Friend or Life Giver Perk for special dialogue options, commenting on the abundance of wildlife or state the oasis seems teeming with life, respectivly, but these options have no effect on the outcome. After speaking to Harold the first time, Birch will give the player the Birch's Sap that will cease Harold's growth. Birch seems to be a memorandum of James Birch, an environmentalist in Fallout 2 that tells the Vault Dweller "the trees own the land". Tree Father Birch might even be a descendant of James Birch.

The 50-year-old chief of Oasis, Birch spends most of his time in the Pavilion, siting on his throne, occasionally eating, and sleeping for a few hours at night. He also walks around Oasis, overseeing the village more directly. While the village is ostensibly a demoratic commune, Tree Father Birch sees himself as the group's spiritual and temporal leader. He has cast himself in role similar to a high preist, worshipping the god spirit, Harold
