In 2007, Penn acquired about {{convert|35|acre|ha}} between the campus and the [[Schuylkill River]] at the former site of the [[Philadelphia Convention Hall and Civic Center|Philadelphia Civic Center]] and a nearby {{convert|24|acre|ha|adj=on}} site then owned by the [[United States Postal Service]]. Dubbed the Postal Lands, the site extends from [[Market Street (Philadelphia)|Market Street]] on the north to Penn's Bower Field on the south, including the former main regional U.S. Postal Building at 30th and Market Streets, now the regional office for the [[United States Internal Revenue Service|U.S. Internal Revenue Service]]. Over the next decade, the site became the home to educational, research, [[biomedical engineering|biomedical]], and [[Mixed-use development|mixed-use]] facilities. The first phase, comprising a park and athletic facilities, opened in the fall of 2011.

In September 2011, Penn completed the construction of the {{USD|46.5 million|long=no}}, {{convert|24|acre|ha|adj=on}} Penn Park, which features passive and active recreation and athletic components framed and subdivided by canopy trees, lawns, and meadows. It is located east of the Highline Green and stretches from [[Walnut Street (Philadelphia)|Walnut]] to [[South Street (Philadelphia)|South Street]]s.

Penn maintains two arboreta. The first, the roughly {{convert|300|acre|sp=us|adj=on}} Penn Campus Arboretum at the University of Pennsylvania, encompasses the entire [[University City, Philadelphia|University City]] main campus. The campus arboretum is an urban forest with over 6,500 trees representing 240 species of trees and shrubs, ten specialty gardens and five urban parks,<ref name="arbnet">{{cite web |url=http://www.arbnet.org/morton-register/penn-campus-arboretum-university-pennsylvania-0 |title=Penn Campus Arboretum at the University of Pennsylvania |website=arbnet.org |access-date=March 19, 2021 |archive-date=April 19, 2021 |archive-url=https://web.archive.org/web/20210419031738/http://www.arbnet.org/morton-register/penn-campus-arboretum-university-pennsylvania-0 |url-status=live }}</ref> which has been designated as a Tree Campus USA<ref>{{cite web|url=https://www.arborday.org/programs/tree-campus-higher-education/|title=Tree Campus Higher Education at arborday.org|website=arborday.org|access-date=December 19, 2023|archive-date=December 2, 2023|archive-url=https://web.archive.org/web/20231202212455/https://www.arborday.org/programs/tree-campus-higher-education/|url-status=live}}</ref> since 2009 and formally recognized as an accredited ArbNet Arboretum since 2017.<ref name="arbnet"/> Penn maintains an interactive website linked to Penn's comprehensive tree inventory, which allows users to explore Penn's entire collection of trees.<ref>{{cite web |url=http://www.facilities.upenn.edu/ |title=Welcome |work=University of Pennsylvania Facilities & Real Estate |publisher=University of Pennsylvania |access-date=March 19, 2021 |archive-date=March 4, 2021 |archive-url=https://web.archive.org/web/20210304222559/https://www.facilities.upenn.edu/ |url-status=live }}</ref> The 92-acre second arboretum [[Morris Arboretum]] is the official arboretum of the [[Pennsylvania|Commonwealth of Pennsylvania]] and includes more than 13,000 labelled plants of 2,500 types, representing the temperate floras of [[North America]], [[Asia]], and [[Europe]], with a primary focus on Asia.
