Texas Invasive Species BioBlitz 2021

May 14, 2021

Saturday May 15 through Sunday May 22 is National Invasive Species Awareness Week. This is a perfect opportunity for the Texas Invasive Species Bioblitz via iNaturalist.

In the 2020 Texas Invasive Species Bioblitz on iNaturalist, we had 3,104 observations of 121 species. There were 867 observers, and 299 identifiers.  Let’s see if we can beat that this year!

Any observations of species from the project list that are made in Texas May 15-22, 2021 will be automatically added to this project. It’s a pretty extensive species list. If you’re not sure if your organism is on it, go ahead and make the observation and if it is confirmed to be on the list, it’ll count!

To get started on iNaturalist, check out these links.



You can learn more about any of the invasive species on the list by visiting

If you have previously submitted records of invasive plants, you might want to return to the same place and take a new observation, and mention in your notes if you think the population is expanding, contracting, or changing, and if any attempted control efforts may have had an effect. You can include a link to those previous records too.

Happy hunting!
