pigface

PIGFACE
These succulent ground cover plants are quite showy when in flower.They prefer a dry,saline location near the coast,two species are common here.

ANGULAR  PIGFACE  Carpobrotus  rossii  
A spreading succulent 2 -3M wide,name derived from the triangular cross section 
of leaves.Stems to 1 m or more long, 3-11 mm thick; leaves glaucous, often slightly 
thicker than wide, mostly 3.5-10 cm long, 6-11 mm wide. Flowers 3.5-5.5 cm diam.

mistletoes

I don't venture out often at this time of the year due to the heat and parched scrubland,but on a recent outing I noticed the mistletoes and wattles were flowering despite the dry conditions.I have to begin this blog somewhere,so I decided on something seasonal.

MISTLETOES
Mistletoes are legendary plants which grow as parasites on the branches of  trees and shrubs.Their seeds are deposited in the droppings of birds which eat the fruit.
There are two species commonly seen in this area.


HARLEQUIN  MISTLETOE   
  Lysiana  exocarpi
Leaves narrow-linear to oblong, 30-150 X 1-10 mm, flowers usually red, rarely yellow.
Fruit ovoid to ellipsoid, 6-10 mm long, red or black.Parasitic on a wide range of hosts but not Eucalyptus. W.Aust.; N.T.; Qld; N.S.W.; Vic.Flowers throughout the year,mainly Summer.  



TEA - TREE  MISTLETOE
Amyema  melaleuca
 Leaf lamina lanceolate to narrow-spathulate, 20-45 mm long,,exclusively parasitic on Melaleuca.Flowers red, November - April.Fruit nearly globular, 6-8 mm long.thrives in coastal situations, S.A and W.A

Flora & Fauna



FLORA AND FAUNA OF LINCOLN COVE

The following posts are by no means a complete inventory,as I have only included species
         I could identify with some accuracy.Also included are introduced species and place of origin,asI have noted many native birds feed on the seeds.
For reference I have use,and can recommend,the following local publications:
WILDFLOWERS OF LOWER EYRE PENINSULA
Hazel O'connor,Janet Smyth,Isobel Smith,Christina Haldane,Ursala Halls.
QUIETER WILDFLOWERS OF LOWER EYRE PENINSULA
Janet Smyth & Brian Saunders.
ORCHIDS OF LOWER EYRE PENINSULA
Jane Hutchinson & Pam Hewstone.
BIRDS OF LOWER EYRE PENINSULA
Colin Gill & Hazel O'connor. 
Also I find Electronic Flora S.A is an excellent site to assist with identification.

history

BRIEF HISTORY OF LINCOLN COVE
I have relied mainly on childhood memories,having frequented this area from an
early age,becoming familiar with the bushland and coastline which was pristine
in those times.Dates and locations may be approximate only.
 Lincoln Cove was originally a tidal salt water creek,ironically named Salt Creek.
This creek was a nursery for a variety of fish ,including Australian Salmon,King
George Whiting,Yellow Eye Mullet and Flounder.It was also a favourite haunt
 of many water birds,among them Ducks,Stilts,Plovers,Comorants and both local
and migratory waders.

SALT CREEK - MY IMPRESSION CIRCA 1950

Around 1945 a landfill rubbish dump was created at the Western arm of Salt Creek
and as a result of the oil and chemicals leached from it at high tide,the mangroves
and the ecology they supported were destroyed.I can recall a tall stand of mangroves
in the middle of the creek and the crab burrows beneath the roots,the last surviving
bush was buried along with the remains of aboriginal fish traps during the construction
of stage 1 of Lincoln Cove.

 GOOGLE EARTH - CIRCA 2012

 At peak tides during Winter Salt Creek almost connected with the Northern beach of
 Proper Bay,making Murray's & Billy Light's Points a virtual island.The only access
to  this area was via the beach and rough limestone tracks,there was also a rifle range
situated parallel with the beach,restricting access when in use.This later became a light
plane landing strip and eventually a greyhound racing track,before becoming part of
the landfill dump.

 REMAINING SALINE VEGETATION

At this time there is still enough native salt water vegetation to attract birds,but this
will eventually vanish as stage 3 of Lincoln Cove begins.While I am not completely
anti - development,I hope sanity prevails and serious consideration is given to
preserving part of the remaining environment for future generations before it's all gone.

TYPICAL WETLANDS SCENE

In the 1950s a causeway was constructed over th entrance to Salt Creek to access Port
Lincoln's sewer outlet at Billy Light's Point and a holiday village installed on on the
present site of the Leisure Centre.Later developments include B.H.P bulk sand facility,
boat ramp,picnic area and slipway.The B.H.P became redundant in the 1990's and
Ospreys still use the old jetty as a nesting site.

 PRESENT DAY MARINA

The first stage of Lincoln Cove began in the 1980's and the second stage completed in
the 1990's,planning has begun for stage 3 with some native vegetation already removed.
