Seminar Agenda:


9 to 9:10 – Welcome and Orientation

9:15 to 10:15 – City of Lewisville Tree Canopy Survey:
Speakers; Stacie Anaya, Director of Lewisville Parks and Recreation and Russell Marusak, Environmental/Natural Resources Team Leader, Halff Associates, Inc.

What exactly is a tree canopy survey? If you want to manage your trees, you need to know what’s there. What are the different types of surveys? What are the objectives of different surveys, and what do you learn from each? Why is Lewisville doing one? How is the Lewisville survey being done, and what about the pre-survey guesses vs what was actually found? What do we hope to learn from the survey, and most importantly, how will the results guide the efforts to create a more livable and comfortable city?

10:20 to 11:20 am – Carbon Capture of Native Trees:
Speaker; Dr. Alexandra Ponette-Gonzalez, Assistant Professor of Geography at UNT via Zoom. Dr. Ponette-Gonzalez conducted a very interesting study to measure and compare the native Post oak tree vs. the Live oak trees, the output of oxygen and the amount of carbon sequestration in the soil. She found that the native Post oak tree gives off about two times as much oxygen into the air and captures about twice the amount of black soot in the soil compared to the Live Oak tree.

11:30 am to 12:30 pm – Lunch and Native Trees Slide Show

12:30 to 1:30 pm The Effects of the 2022 drought on our Trees:
Speaker: Mike Sills, Dallas County Urban Forester TFS
Mike will discuss the damage that drought causes to trees in general and the specific effects of last summer’s hot, dry weather on the local tree canopy.

1:30 to 3:00 pm – Native Trees of North Texas, Talk and Walk:
Speakers; Rick and Lisa Travis, Texas Master Naturalists, Blackland Prairie Chapter

Join Rick and Lisa Travis for an introduction to our native trees. Their presentation will talk about what North Texas trees are most valuable to wildlife, and the different ways and parts of the tree wildlife make use of. Following the talk, weather permitting, we will go on a tree ID hike through Thrive Nature Park across the street.
