Comments about Life History:

Code Comment
034 Vulnerability to cold temperatures may be a limiting factor *004*.
003 Usually epiphytic on the bases of buttonbushes. Can form conspicuous, large tussocks or hummocks rooted on the submerged remains after a buttonbush dies *002*. Grows with hummocks of carex, hibiscus, and buttonbush, and floating mats of dulichium, sphagnum, menyanthes and glyceria *003*. Also occurs on floating or partially submersed, rotting cypress logs *004*.
099 Vegetative stems usually poorly developed, reduced to basal cluster of leaves *002*.
042 Short or poorly developed rhizomes *002*.
047 Emergent aquatics *002*.

Management

Beneficial Management Practices:

Water - control sedimentation
Water - control pollution (thermal, physical, chemical)
Water - develop/maintain streamside vegetation
Water - restrict human disturbance
Water - protect the watershed to reduce the threat of flooding

Beneficial Management References: 004

Adverse Managment Practices:

Water - application of herbicides
Water - dredging and filling
Water - drainage of wetlands, marshes, ponds, lakes

Adverse Management References: 004

Comments on Management:
Habitat protection is the primary management need. This includes protecting the occupied habitat as well as upstream areas within the watershed. Frequent flooding episodes and heightened floodwater elevations devastate existing populations. The species is not able to survive in areas where water levels fluctuate significantly throughout the year. Thus, natural, constant water levels should be maintained. Developing and maintaining streamside vegetation will provide a buffer to protect populations from herbicide drift or other factors. Other threats to populations include: conversion of natural ponds to stock watering holes, road grading of populations located on roadbanks within swamps, and boat wake disturbances *04*.
