civil engineer Steve Salzman headed Luna's "medical team" which designed and built a bracing system to help the tree withstand the extreme windstorms with peak winds between . They were assisted by Humboldt State University professor Steven Sillett. As of spring 2007, the tree was doing well with new growth each year. Caretakers routinely climb the tree to check its condition and to maintain the steel guywires. Luna is under the stewardship of Sanctuary Forest, a nonprofit organization. Post-tree sit Since her tree sit, Hill has become a motivational speaker (holding some 250 events a year), a best-selling author, and the co-founder of the Circle of Life Foundation (which helped organize We The Planet, an eco-friendly music tour) and the Engage Network, a nonprofit that trains small groups of civic leaders to work toward social change. Ecuador oil pipeline protest On July 16, 2002, Hill was jailed in Quito, Ecuador, outside the offices of Occidental Petroleum, for protesting a proposed oil pipeline that would penetrate a virgin Andean cloud forest that teems with rare birds.

But the environmental destruction we saw along the pipelines that had already been built was horrendous." Ecuadorian President Gustavo Noboa commented: "The little gringos have been arrested, including the old cockatoo who climbs trees." Hill was later deported from Ecuador. Tax redirection In 2003, Hill became a proponent of tax redirection, resisting payment of about $150,000 in federal taxes, donating that money to after-school programs, arts and cultural programs, community gardens, programs for Native Americans, alternatives to incarceration, and environmental protection programs. She said: Farm sale protest In 2006, Hill protested the sale of the South Central Farm in an attempt to save the farm from developers. Looking forward In an April 2009 interview, Hill pondered what would come next for her: Popular culture Hill has been the subject of several documentaries, interviews, and books, including her own 2000 memoir, The Legacy of Luna, and has influenced numerous musicians. On December 10, 1998, a benefit concert was played at the Mateel Community Center in Redway, California, during Julia's "tree sit". Artists performing were Bob Weir and Mark Karan as an acoustic duet, the Steve Kimock Band, and the Mickey Hart Band. Hill took part in the event, reading her
