Britton’s beargrass

Britton’s beargrass (Nolina brittoniana)
Plant Botanical Name: 
Nolina brittoniana

Nolina brittoniana, also known as Britton's beargrass, is endemic to the dry scrub-covered ridges and sand hills of central Florida. Like many plants from the southern United States, it is dependent upon periodic fires that reduce competition from other plants and also release nutrients from burned organic matter into the nutrient-poor soil. This vulnerable plant is threatened by fire suppression and by habitat loss resulting from land clearing for residential development and agricultural production. Currently, efforts are being made to monitor, protect and preserve germplasm from populations of Nolina brittoniana and other threatened plant species that share its habitat.
