"Our goal was to fund and distribute a free resource guide to help citizens, developers, and property owners make informed decisions on tree selection, landscape design, and maintenance procedures. We knew of no other publication that combined these elements into one resource that was specific to central Oklahoma.";"This book is designed to guide you through the process of choosing the right tree for your site, deciding where it should go in your landscape, and then properly planting and caring for your tree."

"At The Nature Conservancy, we have always strived to ensure that people can thrive along with the landscapes we love. And since our work is grounded by science, we've used science to tell us what we need to focus on to ensure that our planet, with its growing human population, can survive without destroying the resources on which we depend."

The digital collection includes the nine volumes of the print edition and a supplementary volume covering Olmsted’s writings on public spaces, accompanied by extensive illustrations. Olmsted’s writings as a journalist and a designer give new insights into his projects but also the conditions of late nineteenth century America. He traveled through the southern states as a journalist, imagined how universities might realize design possibilities, and added new considerations to space and health and much more.
