2019 (approx.)

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.
