Tree Pitts­burgh is an envi­ron­men­tal non-prof­it orga­ni­za­tion ded­i­cat­ed to enhanc­ing com­mu­ni­ty vital­i­ty by restor­ing and pro­tect­ing the urban for­est through tree plant­i­ng and care, edu­ca­tion, advo­ca­cy, and land con­ser­va­tion. Tree Pitts­burgh is a reg­is­tered 501( c )3.


Our vision is to cre­ate a healthy urban for­est for all by inspir­ing and engag­ing peo­ple to main­tain, plant, and pro­tect trees.

A green­er city will cre­ate more vital com­mu­ni­ties for gen­er­a­tions to come.


Grow­ing out of cit­i­zen con­cern for the health and well­be­ing of the City’s urban for­est, mem­bers of the Pitts­burgh Shade Tree Com­mis­sion orga­nized Tree Pitts­burgh, for­mer­ly Friends of the Pitts­burgh Urban For­est, in 2006 to car­ry out fundrais­ing, edu­ca­tion, and stew­ard­ship activ­i­ties aimed at restor­ing and pro­tect­ing Pitts­burgh’s trees.
