Fakahatchee Grass Guide: Identification Tips

The Fakahatchee Grass, also known as Tripsacum dactyloides, is a type of grass native to the southeastern United States, particularly in the state of Florida. It is a perennial grass that grows in dense clusters, with stems that can reach up to 6 feet tall. The Fakahatchee Grass is an important component of the ecosystem in the Fakahatchee Strand State Preserve, where it provides habitat and food for various wildlife species. In this guide, we will provide identification tips and information on the characteristics of the Fakahatchee Grass.

Physical Characteristics

The Fakahatchee Grass has several distinctive physical characteristics that can help with identification. The stems are robust and can grow up to 6 feet tall, with a diameter of up to 1 inch. The leaves are flat and linear, with a length of up to 2 feet and a width of up to 1 inch. The leaves are also slightly hairy, with a smooth margin. The inflorescence is a dense, spike-like panicle that can grow up to 1 foot long, with multiple branches and spikelets. The spikelets are arranged in two rows, with the upper spikelet being sterile and the lower spikelet being fertile.

Leaf and Stem Characteristics

The leaves of the Fakahatchee Grass are a key identifying feature. They are flat and linear, with a smooth margin and a slightly hairy surface. The leaves are also slightly keeled, meaning they have a longitudinal ridge running along the midrib. The stems are robust and can grow up to 6 feet tall, with a diameter of up to 1 inch. The stems are also slightly hairy, with a smooth surface. The internodes are long and narrow, with a length of up to 6 inches.

Habitat and Distribution

The Fakahatchee Grass is native to the southeastern United States, particularly in the state of Florida. It grows in a variety of habitats, including wetlands, swamps, and marshes. The grass is also found in disturbed areas, such as roadsides and fields. The Fakahatchee Grass is a perennial grass, meaning it grows back year after year from the same roots. It is also a clonal grass, meaning it can produce new shoots from underground rhizomes.

Soil and Climate Requirements

The Fakahatchee Grass requires full sun to partial shade and moist to wet soil. It can grow in a variety of soil types, including clay, silt, and sand. The grass is also tolerant of flooding and can grow in areas with standing water. The ideal temperature range for the Fakahatchee Grass is between 65°F and 95°F, with an annual rainfall of at least 30 inches.

Conservation Status

The Fakahatchee Grass is listed as a species of special concern by the Florida Department of Agriculture and Consumer Services. The grass is threatened by habitat loss and degradation, as well as competition from invasive species. Conservation efforts are underway to protect the Fakahatchee Grass and its habitat, including the establishment of protected areas and the control of invasive species.

Threats and Conservation Efforts

The Fakahatchee Grass is threatened by several factors, including habitat loss and degradation, competition from invasive species, and climate change. Conservation efforts are underway to protect the grass and its habitat, including the establishment of protected areas and the control of invasive species. Additionally, research and monitoring are being conducted to better understand the ecology and conservation of the Fakahatchee Grass.
