Overview

Lactuca saligna is a species of wild lettuce known by the common name willowleaf lettuce, and least lettuce. It is native to Eurasia but it grows in many other places as an introduced species, including much of North America.

Least Lettuce (Lactuca saligna) faces severe population declines primarily due to habitat loss from agricultural intensification and urban development of its preferred wetland and coastal marsh environments. The species is particularly vulnerable to changes in water levels and salinity, making it highly susceptible to climate change impacts and coastal development pressures.

Frequently asked questions

Why is Least Lettuce classified as Critically Endangered?
Least Lettuce is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Least Lettuce (Lactuca saligna) faces severe population declines primarily due to habitat loss from agricultural intensification and urban development of its preferred wetland and coastal marsh environments. The species is particularly vulnerable to changes in water levels and salinity, making it highly susceptible to climate change impacts and coastal development pressures.
Where does Least Lettuce live?
Least Lettuce occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
