Narrow-leaved Cattail
Typha angustifolia
Typha angustifolia is a perennial herbaceous aquatic plant that can reach heights of up to three meters. It is characterized by its narrow, linear leaves and a distinctive flower spike where the male and female portions are separated by a visible gap of bare stem. This species prefers nutrient-rich, stagnant, or slow-moving waters and often forms dense monocultures in wetland habitats.

Details
Oxygen production
Low direct release into the water; however, transports oxygen via aerenchyma into the root zone (rhizosphere).
Habitat function
Spawning substrate for amphibians; hiding place for juvenile fish; nesting material and site for waterfowl.
Nutrient uptake
Very high; frequently used in constructed wetlands for the reduction of nitrogen and phosphorus.
Food source for
Seeds serve as food for waterfowl; rhizomes for rodents; pollen for insects.
Human use
Used as ecological insulation material; weaving material for mats and baskets; historically used as a source of starch (rhizomes).
Ecology
Ecological role
Important pioneer species for silting processes; provides shelter and nesting sites for specialized bird species such as reed warblers.
Natural predators
Muskrats consume the starch-rich rhizomes; various specialized insect larvae mine within the leaves.
Competitor species
Typha latifolia (Broad-leaf cattail), Phragmites australis (Common reed).
Ecosystem service
Effective water purification through nutrient uptake; erosion control via shore stabilization; carbon sequestration in sediment.
Threats
Destruction of wetlands through drainage; shore construction and intensive recreational use of water margins.
Scientific profile
Profile
Reproduction
Generative via very small, wind-dispersed seeds (anemochory) and vegetative via a vigorous, creeping rhizome system capable of forming dense stands (monocultures).
Protection & threats
Main threats
Destruction of wetlands through drainage, shoreline engineering, and intensive grazing of riparian zones.
