In this episode we talk with field botanist Ernest Herrera about the rich floristic diversity of the Rio Grande Valley region of South Texas and Northern Mexico. We talk about a variety of cool plant species as well as the cultural history and cultural repression of this unique region, how it will adapt to climate change, how to change culture in order to get people to start appreciating their native flora more, how to convince people to kill their lawns, what happened to horned lizards, what's up with Texas Tortoises, and a sh*t ton more. Ernest Herrera is a botanist, herper, and field biologist born and raised in South Texas.
