Thanks to the foresight and devotion of members of the Guada Coma Garden Club, Landa Park was designated as an arboretum in 1982. In 2007, the arboretum was named after William and Dolores Schumann, in honor of their endless devotion to this botanical jewel. The Dolores and Bill Schumann Arboretum is home to over 80 species of trees making it one of the most diverse arboretums in Texas. This arboretum acts as a "living library" of trees, providing a classroom setting for the study of botany, arboriculture and other popular interest.
The Schumann Arboretum trees serve a variety of needs for the community including improving air quality, attracting birds and wildlife, and enhancing the ecosystem of the area.
