The focus of this month’s nature ramble was the diverse plant life associated with the mouth of Painkalac Creek.

We marvelled at the coastal saltmarsh plant species, identified several longstanding weed infestations and re-familiarised ourselves with many of our general coastal plants.

beaded glasswortBeaded Glasswort Salicornia quinqueflora subsp. quinqueflora

Beaded Glasswort, a saltmarsh species which forms extensive carpets in the moist saline soil of the estuary. The leafless succulent plants are comprised of segmented cylindrical branches. The seeds of the Beaded Glasswort are a food source for the endangered Orange-bellied Parrot.

hemichroaTrailing Hemichroa Hemichroa pentandra

This prostrate succulent is another coastal saltmarsh species which forms extensive carpets of vegetation. Flowering over summer these white to pink flowers are generally missed due to their small size, it is well worth getting up close to these beautiful flowers, even if you have to get your knees wet.

creeping brookweedCreeping Brookweed Samolus repens var. repens

Look for this widespread trailing coastal saltmarsh plant when you next visit the estuary. Another summer flowering plant, the white to pink flowers are very easily seen.

creeping monkeyflowerCreeping Monkey-flower Thyridia repens

Small pockets of this delightful prostrate succulent herb can be found growing amongst the previously mentioned coastal saltmarsh plants. The flowers of Creeping Monkey-flower make this species readily identifiable.

marram grassMarram Grass Ammophila arenaria

This northern hemisphere grass now naturalised in Vic. NSW. Tas. SA. & WA. was introduced into Australia in the 1880’s. Overclearing of coastal vegetation by early Europeans had resulted in severe erosion of coastal dunes, a solution was sought, and Marram Grass was introduced as a dune stabiliser. Interestingly Ferdinand Von Mueller, Victoria’s first Government Botanist made the recommendation. The practice of planting Marram Grass for dune stabilisation continued into the 1980’s. Marram Grass is now considered an environmental weed due to the steep dunes it creates which can effect survival of fauna and flora species, e.g. Little Penguin. Marram Grass is also a strong growing plant which out compete native grasses and sedges.

Leaving the estuary, we continued along the track leading to the lighthouse, this King Parrot was certainly more interested in a feed than our group of nature enthusiasts.

Weed of the month

Freesia

Freesia

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.
