This peaceful wetland at Airey’s Inlet was ANGAIR’s destination for the Labour Day Nature Ramble.
A mix of ANGAIR regulars and new comers enjoyed an informative walk through the sanctuary, where many wetland plant species were identified.
By looking at individual Rush species, Juncus spp. the group were able to distinguish between the four species recorded at Allen Noble Sanctuary. It was found that the size of the air spaces within pith (internal region of stem) varied considerably between the species. The diameter and nature of the stem, appearance of the flower and nature of lower leaves also assisted our identification process.
Tall Rush, Juncus procerus
Slender Knotweed Persicaria decipiens and Austral Brooklime, Gratiola peruviana were flowering profusely along the margins of the sanctuary.
The sanctuary provided an opportunity to examine the impressive Red-fruit Saw-sedge, Gahnia seiberiana and compare Sedges in general to the species of Rush we had seen.
Freesia refracta and Freesia alba X F. leichtlinii are declared weeds in the Surf Coast Shire because they spread easily and threaten to invade bushland. Freesias are perennial herbs that die back in summer and produce new foliage in winter. The highly fragrant trumpet-shaped flowers appearing in spring are white to cream and pink with yellow markings, shaded purple on outer surface. Each plant has at least two corms, one below the other, thus requiring deep digging to remove them.
More details about how to control this weed can be found in the archive of Weeds of the Month.
There are a number of wonderful local Friends Groups that provide ANGAIR members and the community with opportunities for involvement.
