Description

A description of Cyperus retrorsus is provided in The Flora of North America. Cyperus retrorsus is a perennial graminoid. Most individuals are composed of 1-3 stems. [1]

Distribution

C. retrorsus is natively distributed from south New York south to Florida and west to Texas. It is mostly found within the Gulf Coastal Plain, but can also be found up to Kentucky and west to southeast Oklahoma.[2]

Ecology

Habitat

C. retrorsus requires wet summers and dry winters.[3] It also prefers higher light levels associated with open or semi-shaded conditions, and moist to wet sandy soils. [1] It has been observed growing in a variety of related soil types, including wet sand, moist sandy peat, moist loamy sand, drying sandy soil, drying loam, peat, and dry sterile sand. [1]

As such, this species can be found in or near wet habitat like pocosin communities,[4] lake shores, phosphate pools, marshes, lakeside sinkhole berms, drained bogs, river floodplains, seepage streams, and drying wetland depressions. [1] However, it also can be found in drier areas, including flatwoods communities,[5] and longleaf pine communities.[6] Additionally, it has been found in oak-hickory forests, grassy areas on islands, turkey oak sand ridges, sandhills, live oak hammocks, dried lake bottoms, pine flatwoods-savannas, old stabilized sand dunes, prairies, open scrub, and scrub barrens. [1]

Along with being found in natural community types, C. retrorsus has been found in disturbed habitat such as cleared floodplains, roadside ditches, railways, trail edges, clear-cuts, fallow fields, borrow pits, dredge spoils, former pine plantations, orange groves, longleaf pine restoration sites, and disturbed sandhill communities. [1] C. retrorsus responds positively to soil disturbance by agriculture, indicating areas of post-agricultural woodland.[7] In Central Florida it showed no response to soil disturbance by clearcutting, bracke seeding, high-severity burning, and salvage logging. However, C. retrorsus exhibited a positive response to soil disturbance by some clearcutting, single roller chopping, and broadcast seeding.[8]

Associated species include Paspalum notatum, Eupatorium mohrii, Rubus cuneifolius, Ludwigia maritima, Pityopsis, Solidago fistulosa, Aletris lutea, Eleusine, Dactyloctenium, Digitaria, Panicum, Rhynchospora fernaldii, R. fasicularis, Andropogon, Scleria reticularis, Trilisa, Liatris, Aristida, Andropogon, Bulbostylis, Clitoria, Juncus, Pteridium aquilinum, Cyperus filiculmis, Commelina erecta, Serenoa repens, Sagittaria graminea, Woodwardia virginica, Nyssa biflora, Acer rubrum, Liquidambar styraciflua, Rynchospora fernaldii, R. fascicularis, Carex longii, madien cane, and others. [1]

Phenology

This species has been observed to flower between July through October.[1][9]

Seed dispersal

This species is thought to be dispersed by gravity.[10][11]

Seed bank and germination

It accounted for 29% of a late-summer Virginia pocosin seed bank.[4] It was also found viable in the seedbank in a pine flatwoods site in Florida after 8 years of fire exclusion[12] and in the seed bank of a longleaf pine community in the western panhandle region of Florida. [6]

Fire ecology

C. cyperus has been found in burned areas including recently burned slash pine-scrub flat, annually burned savanna, and frequently burned mature longleaf pine-wiregrass communities, indicating a level of fire tolerance. [1]

It responds best to a moderate-severity level burn. Recovery after fire is achieved by resprouting and seed.[3] Abundance was found to significantly decrease over 25 years after fire in a scrubby flatwoods, suggesting the significance of fire in its life history.[13]

Use by animals

It consists of approximately 2-5% of the diet for large mammals, and 5-10% of the diet for small mammals, water birds, and terrestrial birds.[14]

Conservation and management

This species is listed as endangered by the New York Department of Environmental Conservation Division of Land and Forests, and listed as extirpated by the Pennsylvania Department of Conservation and Natural Resources.[15]
