Early Detection News

Meet GIS Intern Shea Nolan, get a peek at post-field season indoor botany, and test your invasive species ID skills in this fall-winter issue. Also catch invasive species profiles of two grassland troublemakers, Bromus tectorum and Rytidosperma penicillatum, and a native species profile on the charming redwood forest floor groundcover Oxalis oregana.

You'll find coastal wetland wonders, Point Reyes post-fire monitoring, September invasive species surveys in the Presidio, and salt marsh plant community surveys featured in this issue. Noteworthy invasive species profiles include false ice plant and oxeye daisy, and don't miss a native species spotlight on the sticky, strangely shaped Point Reyes bird’s-beak, a threatened species in California!

Internship projects, invasive species early detection surveys across Golden Gate, and plant community surveys in squishy salt marshes and dense Douglas-fir forests are among the features in this August issue of Botany News. You'll also find info on two high priority invasive plants to look out for, parrot's feather and old man's beard, and a native species spotlight on the beautiful, sturdy, and ecologically and ethnobotanically significant blueblossum ceanothus.

This July, the Invasive Species Early Detection team mapped invasive plants at John Muir National Historic Site and at Rancho Corral de Tierra and the Presidio of San Francisco in Golden Gate National Recreation Area. Yellow star thistle, Algerian sea lavendar, and Oppositeleaf Russian thistle emerged as noteworthy early detections. Meanwhile, the Plant Community Monitoring team surveyed freshwater marsh plots and shine a spotlight on the ecological benefits of poison oak.

Beyond the breath-taking views that give Bay Area national parks their claim to fame lie incredibly diverse plant communities. Since 2013, National Park Service botanists, seasonal technicians, interns, and volunteers have established and revisited over 150 permanent plots, building a baseline for long-term data collection. This summer's botany team has hit the ground running, enjoying snacks on the hillsides of Tennessee Valley and sleeping beneath the stars in Pinnacles.

The Invasive Species Early Detection Team (ISED) conducted surveys in 2019 at Golden Gate National Recreation Area (GOGA), Point Reyes National Seashore(PORE), John Muir National Historic Site (JOMU), and Pinnacles National Park (PINN). Noteworthy detections this year included yellow star thistle and purple star thistle at GOGA, poroporo and Jimson weed at PORE, cheat grass and smilo grass at PINN, and stinkwort at JOMU.

The Invasive Species Early Detection Team (ISED) conducted September surveys at Point Reyes National Seashore and Golden Gate National Recreation Area North District. Noteworthy detections this month included reed canary grass, Johnson grass, and horehound.

The Invasive Species Early Detection Team (ISED) conducted August surveys at Point Reyes National Seashore and Golden Gate National Recreation Area North District. Noteworthy detections this month included malfurada, Klamathweed, purple starthistle, and Andean tussockgrass.

The Invasive Species Early Detection Team (ISED) conducted July surveys at Point Reyes National Seashore and John Muir National Historic Site. Noteworthy detections this month included yellow star thistle, small leaf spiderwort, mourningbride, and poroporo.

Invasive Species Early Detection (ISED) team surveys began in April. They will be concentrated at Point Reyes National Seashore this year, with some additional work at Pinnacles National Park and John Muir National Historic Site.
