The St. Andrew's Queen of the Highlands is required to participate in a philanthropy project during her reign. Fiona promoted the Arbor Day Foundation as her project.

Fiona hosted a Highland Lads' & Lassies' Golf Outing at The Royal Oak Golf Center with an afterglow at Lily's Seafood restaurant in Royal Oak to help raise money and awareness for the the National Arbor Day Foundation. The Arbor Day Foundation inspires people to plant, nurture and celebrate trees. Arbor Day is a nationally-celebrated observance that encourages tree planting and care. The idea for Arbor Day originally came from Nebraska. A visit to Nebraska today wouldn't disclose that the state was once a treeless plain. Yet it was the lack of trees there that led to the founding of Arbor Day in the 1800s.

Among pioneers moving into the Nebraska Territory in 1854 was J. Sterling Morton from Detroit. He and his wife were lovers of nature, and the home they established in Nebraska was quickly planted with trees, shrubs and flowers.

On January 4, 1872, Morton first proposed a tree-planting holiday to be called “Arbor Day” at a meeting of the State Board of Agriculture. The date was set for April 10, 1872. Prizes were offered to counties and individuals for planting properly the largest number of trees on that day. It was estimated that more than one million trees were planted in Nebraska on the first Arbor Day.

During the 1870s, other states passed legislation to observe Arbor Day, and the tradition began in schools nationwide in 1882.

Today the most common date for the state observances is the last Friday in April, and several U.S. presidents have proclaimed a national Arbor Day on that date. But a number of state Arbor Days are at other times to coincide with the best tree planting weather, from January and February in the south to May in the far north.

Fiona became a member of the Arbor Day Foundation and with her membership received 10 tree's to plant. She planted trees in some of her favorite spots and hopes to be able to plant one at the Society's new building when it is built.
