TL;DR: In this paper, the Lagoon Beach area is mapped and described, and the vegetation of the lagoon area is classified into three main species/stand groups: wombat-grazed, closed-herbfields dominated by Samolus repens and Schoenus nitens, and characteristic heath species such as Casuarina monilifera and Hypolaena fastigiata.
Abstract: The vegetation of the Lagoon Beach area is mapped and described. Classification
and ordination of thirty-five randomly located quadrats, and central chi-squared distribution analysis of association
between species, reveal three main species/stand groups. The wombat-grazed
closed-herbfields dominated by Samolus repens and Schoenus nitens form one strong
group associated with the lagoonal flats. A second group consists of stands which
include characteristic heath species such as Casuarina monilifera and Hypolaena fastigiata.
A third, less well-defined group consists mainly of Eucalyptus viminalis open
forests with an understory characteristically dominated by pteridium esculentum. The
factors that could be responsible for the differentiation of the vegetation of the
area are discussed, and a species list is appended.
TL;DR: There have been very few studies of pollination in saltmarsh species and while casual observation suggests that a variety of insects are visitors to such flowers, there does not appear to have been any study in Australia which has identified the species concerned or has confirmed that they are indeed effective pollination agents.
Abstract: There have been very few studies of pollination in saltmarsh species. It has been generally assumed that many species (notably in the Chenopodiaceae, Cyperaceae, Juncaceae and Gramineae) are wind pollinated while those with showy flowers (for example Samolus repens and Selliera radicans) are insect pollinated. While casual observation suggests that a variety of insects are visitors to such flowers, there does not appear to have been any study in Australia which has identified the species concerned or which has confirmed that they are indeed effective pollination agents (similar remarks could be made about the state of knowledge for all other habitat types).
In the case of species regarded generally as wind pollination there is now a number of reports, from various parts of the world, of pollen collection by insects. Pollen collection from the clubrush Scirpus (Bulboschoenus) maritimus was described by Leereveld, Meeuse and Stelleman (1981). Pojar (1973) discussed pollen collection from a number of saltmarsh species in Canada by bumble bees. Keighery (1979) reported pollen collection by honey bees and syrphid flies from Suaeda australis.
