Tree Ten­ders are on the front lines of car­ing for the urban for­est. Tree Ten­ders is our flag­ship course that teach­es you all about trees and how to become an advo­cate for them in your neigh­bor­hood. This course cov­ers urban forestry prac­tices, tree biol­o­gy and health, basic tree iden­ti­fi­ca­tion, prop­er prun­ing and main­te­nance, and instruc­tion on how to lead your com­mu­ni­ty in orga­niz­ing tree plant­i­ngs and tree care.

Why Tree Tenders?

Tree Pitts­burgh loves all of our vol­un­teers! But for those want­i­ng to take their vol­un­teerism to the next lev­el, we rec­om­mend the Tree Ten­ders Course. Tree Ten­ders not only help to care for young trees, but gar­ner com­mu­ni­ty sup­port and orga­nize Tree Care Events for their neighbors!

Tree Ten­ders also have the unique oppor­tu­ni­ty to help us care for young trees through Prun­ing Work­shops. These events are only open to those who have com­plet­ed our Tree Ten­ders Course and received their cer­ti­fi­ca­tion. Prun­ing work­shops pro­vide small-group instruc­tion on prun­ing under the super­vi­sion of our ISA Cer­ti­fied Arborists around the City of Pittsburgh.

We also offer Tree Ten­ders cer­ti­fi­ca­tion for facil­i­ties man­age­ment, munic­i­pal employ­ees, and oth­er groups. Tree Ten­ders Cours­es are intend­ed for groups 16 and over. For infor­ma­tion on Tree Ten­ders Cours­es for youth, reach out to Edu­ca­tion Coor­di­na­tor Maeve Raf­fer­ty at maeve(at)


Tree Ten­ders are our num­ber one source of vol­un­teers for neigh­bor­hood street tree care. Whether you bring a group of neigh­bors or just your fam­i­ly, we’re excit­ed to have our Tree Ten­ders com­mu­ni­ty work­ing with us.
