This accreditation upgrade was earned in part by:

  • Formalizing the arboretum management program
  • Increasing collaboration with other professional organizations
  • Building opportunities to educate the public and Capitol Hill community about the importance of the arboretum and urban forests

The U.S. Capitol Grounds is now just one of 40 accredited arboreta that have attained this level of recognition out of 504 total accredited arboreta.

ArbNet created its Arboretum Accreditation Program to establish and share a widely recognized set of industry standards for the purpose of unifying the arboretum community. No other international program of accreditation exists that is specific to arboreta. Learn more.
