Ecology
Habitat
Common habitats for C. haspan is in tidal marshes, low fields, ditches, and waterfowl impoundments. It requires full sunlight, it has littler tolerance for shaded regions.[1][4] Cyperus haspan has been found to grow well in subtropical and tropical climates and being of the most productive plants in the regions wetlands. [5] Habitats also include wet prairies, broadleaf marshes, and wetland shrubs. They are found to germinate well in flooded environments. [6] Specimens have been collected in the following habitats; river banks, moist loamy sands, pine flatwood clearings, ponds, shallow water, hillside bogs. [7]

Herbivory and toxicology
This species has been observed to be eaten by white-tailed deer.[11]
Conservation, cultivation, and restoration
C. haspan is considered to be possibly weedy or invasive by the Hawaiian Ecosystems at Risk Project.[1] Has been used in landfill restoration areas. [12]
