Bexar Branches Alliance

Trees do more than provide shade. They cool our neighborhoods, improve air quality, reduce flooding, support wildlife, and create healthier communities for future generations.

At Bexar Branches Alliance, we're growing both trees and environmental leaders through Project CANOPY, our hands-on urban forestry and citizen science program.

Since launching Project CANOPY, we have planted 510 trees across five Northside ISD campuses and engaged more than 850 fourth- and fifth-grade students. Students don't just plant trees. They learn about climate resilience, biodiversity, and environmental stewardship, then collect real-world data on tree growth and submit it to the NASA and NOAA-supported GLOBE Program, contributing to scientific research while learning in a living outdoor classroom.

Every tree planted becomes part of the fifth-grade science curriculum, allowing students year after year to monitor growth, track environmental benefits, and develop a deeper connection to the natural world. To ensure long-term success, BBA commits to caring for and monitoring each planting site for three years.

Now we're ready to grow.

With your support, Project CANOPY will expand to 10 additional campuses next school year, planting 1,300 more trees and engaging more than 1,800 students, teachers, volunteers, and community members.

When you support BBA, you're not just planting a tree. You're creating cooler campuses, healthier communities, meaningful educational experiences, and the next generation of environmental stewards.

Together, we can grow a stronger canopy and a brighter future for South Central Texas.
