At edge of large claypan-saltmarsh. Upper tidal zone.

Surprising to find isolated specimen of White-flowered Black Mangrove in southern Moreton Bay. No other members of this species in immediate area.

Mature specimen (it is fruiting), but it is only between 81 and 84 cms in height.

Note: some leaves show characteristic 'notch' at end.

Scale insects (and tiny 'crawlers') visible on some stems - these pests suck sap and damage plants.

At least one ladybird, a potential predator of the pest, is visible (see Photo 6).

Photo 10 shows seeds fallen onto ground beneath.

Photo 12 (panorama) was taken on 24/3/2023 on a previous visit.

Moreton Bay Ramsar internationally important wetland.

GPS accuracy: 3m
Datum: WGS84

Just outside Moreton Bay Ramsar wetland boundary.

Growing amid samphire on soft claypan, not far from creek. Groundwater seepage is available.

New housing and landscaping is nearby, and there is ready access to the claypan on foot and by bicycle.
Given these factors I regard the specimen and its immediate landscape as fragile and perhaps vulnerable to decline.

Surprised to find this specimen, as White-flowered Black Mangroves are rare on Redland's mainland coast.
This may be the southernmost limit of their range on the mainland at the present time. Climate change could impact this species - it has little option to move inland with rising sea-level (due to human infrastructure barriers); it remains to be seen if it is able to migrate southwards.

However, this locality has proven to be fertile ground for the species, with more members being identified close by.
I had previously encountered only one member of the species at Redland (in Geoff Skinner Wetlands), not far to the north.
