What’s in a Hueco? An interpretive hike of aquatic habitats at Hueco Tanks State Park and Historic Site.

Leader: Liz Walsh, Professor of Biological Sciences, UTEP and National Sierra Club Treasurer & Executive Committee Board Member

Duration: 2 hr

Date: October 15

Time: Meet at Hueco Tanks at 9am

Limit: 10

Join Sierran and UTEP Professor Liz Walsh on a hike to explore aquatic habitats at Hueco Tanks. Liz has been studying life in the huecos and other temporary aquatic habitats at Hueco Tanks for over 20 years. During the hike, we will visit very temporary huecos that are the home to specialized communities of animals including fairy shrimp, tadpole shrimp, waterbears and even an endemic species of rotifer. Liz will explain how these organisms persist during prolonged periods of dessication and exposure to the elements. We will also visit larger temporary waterbodies such as Laguna Prieta where, in addition to fairy and tadpole shrimp, hundreds of species of invertebrates thrive during the wet season. Wear sturdy shoes, bring plenty of water and a snack for this 2 hr hike to North and East Mountain sites.​​
