Donations may be made in recognition of a variety of events, for example: in honor of a happy occasion (anniversary, birth, bar/bat mitzvah, birthday, wedding, etc.), or in honor of an individual or family. Donations may be made by an individual or a group, and may be made at three levels: a leaf ($200), an acorn ($500), and a stone ($1,000). A leaf can be engraved with four lines of text with 20 characters in each line, plus a brief fifth line (often a date). Acorns and stones are larger than leaves and can accommodate more text. Sample wordings can be found by looking on the Happy Tree of Life. Memorial plaques are also available for purchase ($250). You will find examples of what to include on the plaque by looking at ones already on the memorial board.
