St Kilda mangroves... about latitude 34 S

Today was a surprise "free" day.  I went to see the St Kilda mangroves on the edge of Gult St. Vincent... about 40 minutes from here on the new freeway.  I've made paintings of them in the past, and that is my plan... so today I went to see them.
These are special mangroves and they need to be taken care of.  They are growing at a much greater latitude (further from the equator) than other mangroves because they have been protected in Gulf St Vinccent and Spencer's Gulf (near Pt Augusta) since Australia was a part of Gondwanaland.
They couldn't become re-established againif they were ever cleared, and so we really need to protect them.  The gulf is known for its fishing, and the baby fish come from these mangrove forests and so we should all want to protect and manage them well.
 A few of them are flowering.  The flowers are tiny and it seems that there are always some of the trees producing some...
 The backs of the shiny leaves often have salt crystals on them....  using sea water has its own salinity issues....

At St Kilda, you can walk along a boardwalk that extends out into the water and the mangrove forest....
 ... and part of it has been covered in seaweed....
 Once out near the ocean, you can look across to outer harbour, the Port River outlet and the Adelaide Hills.  Downtown Adelaide is just visible to the rhs of the double bump of mangrove trees in the rh/centre of the picture....

The red groundcover is samphire and the mangrove forest extends quite a long way inlsnd in such a flat landscape.  Adelaide Hills are in the background again.

Back to St Kilda....
The sailing club looks like a good place to keep a boat.
