Tuesday, April 28, 2015: The Exceptionally High Value of the Much Maligned Hackberry Don Ewers, Master Naturalist and NPSOT member, is this month's speaker. The hackberry tree presents several problems, particularly in an urban environment, that have given it a negative repuation as a "weed" or "trash" tree. However, the hackberry serves as one of the most environmentally valuable trees, especially here in South Texas. The numerous essential environmental benefits of the hackberry will be discussed in this presentation. Time permitting, at the end of the presentation, there will be an opportunity for further discussion of the hackberry, other trees with a similar reputation such as the honey mesquite, and other plants about which there may be questions. 6:30 pm – Native plant/seed exchange & social time 7:00 pm – Program Lions Field Adult Center 2809 Broadway (at Mulberry, by Brackenridge Park) Map to Lions Field Adult Center:
