The San Antonio River Authority (River Authority) staff is committed to safe, clean, and enjoyable creeks and rivers. Still, we need YOU to help us protect and preserve area natural resources for future generations. There are many ways you can get involved and Be River Proud!

We want to highlight your positive actions, so please share pictures or videos of you and your loved ones on social media using #BeRiverProud. Once a month, we will feature your stories on our blog. This month, we highlight a couple of participants in this year’s City Nature Challenge. Read along to learn more!

 

The City Nature Challenge (CNC) is a four-day annual global Bio-blitz held at the end of every April. During the Bio-blitz, citizen scientists worldwide participate in this challenge to observe and document the wildlife in their cities. The main goals of the CNC are 1) helping species of greatest conservation need (SGCN), 2) monitoring changes in the range of native species, and 3) possibly identifying new species. This family-friendly challenge encourages all ages to go outside and observe nature!

This year’s challenge was held from April 29 to May 2. The San Antonio CNC area boundary was also expanded to include Karnes and Goliad counties. Along with Bexar and Wilson counties, these counties comprise the River Authority’s four-county jurisdiction. This challenge is important to our San Antonio River Watershed for a few reasons. First, the CNC serves an essential role in educating the community about the vast biodiversity of species that rely on the creeks and rivers of our watershed. Second, it sheds light on the current health of our watershed, including the status of SCGN that live within it. Third, it helps with the Texas Parks and Wildlife Department’s (TPWD) research and conservation efforts by contributing valuable data to the Texas Nature Trackers

How many observations were made in the san antonio river watershed?

Over 60% of the observations made in the 2022 CNC River Authority Bio-blitz are now research-grade. Expert naturalists and scientists will continue identifying the documented species in this challenge to contribute further research-grade data.
