T. lylei pumps oxygen into the sediment under waterlogged conditions, improving the health of saline aquatic[4] and riparian ecological systems.

Seeds are broadly elliptic and measure 1–1.5 mm long; testes are crustaceous, reddish-brown, and concentrically granular over the embryo.

[5] This process is most effective when the new site is in lightly cultivated, salt-affected areas to enable plants to germinate and spread naturally.

T. lylei's primary threat is from introduced hoofed livestock species such as cattle and sheep, which overgraze and trample the native vegetation.

[2] Stochastic events such as flooding and drought may bring localised extinction, while limited genetic diversity hinders the species ability to adapt to potential environmental changes.
