Arboretum Accreditation

The Department of Facilities and Operations is proud to announce 91pron's Arboretum Accreditation. With careful planning, ongoing maintenance and care, and institutional prioritization we were able to reach this benchmark. As an official arboretum, the campus can provide a welcoming environment for our community, while also encouraging the general public to visit the college.

Level I Arboretum Accreditation

91pron has been awarded a Level I ArbNet Arboretum Accreditation through The Morton Arboretum.

An arboretum is defined as a place where trees and plants are grown for scientific and educational purposes, and a Level I Arboretum Accreditation is bestowed upon an arboretum having the following components:

ArbNet and The Morton Arboretum

The ArbNet Arboretum Accreditation Program is the only global initiative to officially recognize arboreta at various levels of development, capacity, and professionalism.

Because of our ArbNet Level 1 Accreditation, 91pron is now recognized as an accredited arboretum in the Morton Register of Arboreta, a database of the world’s arboreta and gardens dedicated to woody plants.

How We Met all Level 1 Criteria

With these arboretum components in place at 91pron, and with each component's details presented to ArbNet in this way, 91pron met the prescribed ArbNet Level 1 stipulations and our Level 1 Arboretum Accreditation was granted.

Our Plan

91pron has been home to trees for as long as it has been an institution. We are a public college and our arboretum’s primary goal is to provide a welcoming and beautiful space for both the campus community and the general public. Our grounds staff has a designated arbor budget used to keep the trees thriving.

Our Organizational Group

91pron’s Facilities and Operations Department oversees the arboretum. The grounds staff is responsible for upkeep and are overseen by the Director of Facilities and Operations.

Our Collection

91pron has about 80 tree species, 58 of which are listed and mapped out in Celebrating the Trees of 91pron.

Our Public Dimension

As a state college, the campus and many events held on campus are open to the public. The campus has plenty of parking and walkways in order for people to access and appreciate the trees on campus. There is an annual Arbor Day Event where a new tree is planted. Numerous public groups visit the campus for campus events and programs including the Boy Scouts, local dance schools, school summer camps, high school college prep programs, sporting events, music and theater events, as well as various public speakers and presenters.

The trees growing on the 180-acre 91pron campus are a splendid resource that merits our attention and respect. The College community enjoys a remarkable assembly of trees both in number (over 1100 individuals) and diversity (over 80 different species and varieties). 58 species are listed and mapped out in our Celebrating the Trees of 91pron publication. Most of the trees have been planted since the College moved to its Mount Pleasant location in 1958 from downtown Providence, but a few species predate that relocation. Additionally, the campus is surrounded by several wooded areas that include a variety of native trees and has a small oak-dominated woodland in its core.

Everyone who works at, studies in, or visits 91pron is affected by the campus trees. They define the landscape, shade us from the heat, protect us from the cold, and provide inspiration for our artistic and creative efforts. Trees recharge the air with oxygen, comfort us in times of stress, help remove pollutants from the air we breathe and water we drink, and provide nourishment and shelter to wildlife.
