Salinity
The salinity of Swanpool is highly variable (0.5-22 psu) (Carter, 2004). A culvert connects the lagoon to the sea, with the incursion of seawater occurring on very high tides such as spring tides. At the northern end of Swanpool, the lagoon is fed freshwater from the Tregoniggie stream as well as diffuse drainage from a local catchment (Gainey, 1997; Evans, 2003).

Substratum/habitat
Victorella pavida can grow on any hard surface and in Swanpool can be found growing on concrete surfaces, stones, traffic cones and mainly %Phragmites australis%.
