The Lilly ARBOR Project is a part of an experimental riparian floodplain reforestation and ecological restoration program, located along the White River in Indianapolis, Indiana, United States. ARBOR is an acronym for "Answers for Restoring the Bank Of the River".{{cite web |url=https://cees.iupui.edu/research/restoration/lilly-arbor/index.html |title=Lilly ARBOR |website=www.cees.iupui.edu |publisher=Indiana University |access-date=January 24, 2024 |quote=ARBOR is an acronym for Answers for Restoring the Bank Of the River.}}

Project

The riparian forest restoration project was performed by the Center of Earth and Environmental Science (CEES) at Indiana University–Purdue University Indianapolis (IUPUI) with support from the Lilly Endowment.{{cite web |url=http://www.lilly.com/about/citizenship/key_issues/health/health_performance.html |title=Corporate Citizenship: HSE Performance Review |accessdate=July 31, 2007 |date=March 2007 |publisher=Eli Lilly and Company |quote=The Lilly Foundation continues to support the Lilly ARBOR Project |archiveurl=https://web.archive.org/web/20070209172441/http://www.lilly.com/about/citizenship/key_issues/health/health_performance.html |archivedate=February 9, 2007 |url-status=dead}}

As part of the riparian zone restoration project, nearly 1,400 trees were planted along the eastern bank of the White River near downtown Indianapolis. The {{Convert|8|acre|adj=on|spell=in}} project site stretches for about {{Convert|1|mi|spell=in}} from 10th St. (north) to New York St. (south).{{cite web |title=Lilly Arbor Project |publisher=Center of Earth and Environmental Sciences |url=http://cees.iupui.edu/Research/Restoration/ARBOR/index.htm |accessdate=July 31, 2007 |url-status=dead |archiveurl=https://web.archive.org/web/20070804111352/http://www.cees.iupui.edu/Research/Restoration/ARBOR/index.htm |archivedate=August 4, 2007}}{{cite web |author=Salazar |first1=Kara A. |last2=Tedesco |first2=Lenore P. |last3=Atekwana |first3=Eliot A. |last4=Swope |first4=R.

After five years, the Lilly Arbor Project provided data on riparian zone reforestation strategies, which will be used in further research and future projects. Students and faculty from various universities conduct research and maintain the restoration using the CEES service learning program.
