Detailed Description

Retired USGS botanist Linda Pratt, USGS research geologists Patricia Nadeau and Jennifer Lewicki, and USGS chemist Tamar Elias (left to right) are part of a team investigating a critically endangered succulent plant, Portulaca sclerocarpa, in Hawai‘i Volcanoes National Park's Puhimau thermal area. Invasive species, like the broomsedge grass shown here, may contribute to low Portulaca population growth rates. USGS photo by Stephanie Yelenik, November 2019.
