coastal-habitat
Coastal habitats are the dynamic ecosystems where land meets sea, encompassing dunes, salt marshes, mangroves, and rocky shores shaped by tides, salinity, and shifting sediments. For plant science, these environments serve as natural laboratories for studying how species adapt to osmotic stress, periodic flooding, and nutrient-poor or saline soils. Understanding coastal plant adaptations offers insight into stress tolerance mechanisms that can inform conservation efforts and crop resilience research amid rising sea levels and coastal erosion.

Tree tobacco (Nicotiana glauca), an invasive shrub from South America, has been documented at research-grade quality along the La Jolla Coastal Trail in San Diego. This sighting adds to the known spread of this toxic, drought-tolerant plant along Southern California's coastal habitats.
A research-grade observation of tree tobacco was confirmed at La Jolla Coastal Trail, San Diego — meaning multiple identifiers agreed on the species ID.
Tree tobacco (Nicotiana glauca) is an invasive species in California coastal habitats, documented as displacing native vegetation.
The plant contains toxic alkaloids (anabasine) harmful to humans, livestock, and wildlife, raising public safety concerns in a heavily visited recreational area.
