Birds flock to weeds

Port Douglas & Mossman Gazette - - NEWS -

THESE dusky moorhens had no prob­lems with a nox­ious weed chok­ing the lake sur­round­ing the Fern­dale hous­ing es­tate in Port Dou­glas last week.

The re­cent in­fes­ta­tion known as Salvinia mo­lesta had al­most com­pletely cov­ered the man-made lake, with Cairns Re­gional Coun­cil at­tempt­ing to re­claim the wa­ter­way.

“Salvinia mo­lesta is an in­va­sive aquatic weed that prefers the warmer sea­son and un­der op­ti­mum growth can dou­ble in vol­ume ev­ery two to three days,” coun­cil’s nat­u­ral ar­eas man­age­ment co­or­di­na­tor Rus­sell Wild said.

“Coun­cil is us­ing an in­te­grated ap­proach to slow­ing the in­fes­ta­tion with a mix­ture of her­bi­cide, bi­o­log­i­cal, me­chan­i­cal and con­tain­ment booms to con­trol the aquatic pest plant.”
