Malone fulfilled the requirements for a Tree Campus in 2017 with the support of Jason Courter, associate professor of biology and Cynthia Johnson '70. The campus Treewalk project (planned by Johnson and Mike Goff '66) continues Malone's certification and provides an educational experience for the community. Johnson petitioned the Collegium to name the Treewalk in honor of Charles King, professor of botany at Malone College from 1961-1972, who impacted many students to love God’s creation. The Treewalk was dedicated on September 28, 2018.
