Clean Up Australia Day 2018

Despite winds up to 27 km per hour 24 volunteers from Little Bay Scouting and La Perouse Coastcare had a productive  morning cleaning up Molineux Point, Bumborah Point and Yarra Bay beach and dunes.  Scouts leader Ian brought screens to collect small plastics.  Two Ofo bikes were recovered from the Port Botany Revetment Wall  

 

 

Sicilian Sea Lavender & Kudzu Central Coast Field Trip

On a Weeds Field trip to the Central Coast today to see Sicilian Sea Lavender –Limonium hyblaeum (Plumbaginaceae) –   in situ at Saratoga Nature Reserve before its eradication. This invasive species which destroys native salt marsh species, has already taken hold in Victoria .  Fortunately it has only been recorded in NSW at Saratoga and Lake Conjelligo.  Thanks to Nicola Nixon for organising the trip.

Testing Congwong Lagoon

Water Testing yesterday at Congwong Lagoon:  Water Temperature 23;  pH  6;  Electrical Conductivity 680;  Turbidity 18; Coliforms 1300 per 100ml;  Dissolved oxygen 4.7 (55%) Phosphate 0.06 ppm.

Environmental Works Congwong April 2015

In 2013 Caltex was responsible for a major oil spill in Botany Bay and in April 2015 undertook  to provide funds for work on the Gross Pollutant Trap that filters stormwater entering Congwong Lagoon.

Photos from yesterday including signs at the entry to the Beach (6 poles but no bike rack).

Streamwatch Testing at Happy Valley

WEB Corkwood and Weed 7 January 2015 WEB Happy Valley 7 January 2015 WEB Happy Valley site January 7 2015 WEB Tree Ferns 7 January 2015 WEB Tree Ferns and Bridge 7 January 2015

 Tree ferns now tower over the bridge but weed extensive, eg. near the Corkwood – Endiandra sieberi

Results:  Dissolved Oxygen at 11% was well below the boundary limit.  Turbidity and Temperature readings at 15 and 23 respectively were fine.  Electrical conductivity at 560 was higher than usual.  Available phosphate at 0.09 was expected given the extensive weed and runoff.  The e-coli count was around the usual.
