THOMSON/LATROBE RIVER: Australian Grayling are found in some streams in the catchment. Used to have a large population of Blackfish, but due to desnagging, sedimentation and destruction of riparian vegetation these populations have declined. Crayfish are an issue in catchment.
Herbicide Regimes: (Incomplete information provided by sources including Gippsland Water):
This plantation was very likely to be aerially sprayed with 2,4,5-T between 1968 and 1977. The Dioxin TCDD may still exist in soil in this plantation. For more historical data on 2,4,5-T click here.

October 1989: 121.3 ha sprayed with 485.2kg of Velpar ULW. 'The highest levels of hexazinone detected in streamwater were at the Neerim East site, these being 18.0ug/l, five days after application and 17.5ug/l one month later following the largest rainfall measured . . Monitoring was undertaken 2 to 3 km downstream of the treated areas detected trace residues of hexazinone in only three of the 24 samples analysed, the maximum concentration being 1.3ug/L. (Weed Control in Radiata Pine plantation by aerial application of granulated hexazinone - Lands and Forests Technical Report No. 5 Conservation and Environment 1991).
Late 1991: 51 ha sprayed with 204 kg of Velpar ULW to kill A. verniciflua (Varnish Wattle) and A. mucronata (Variable Sallow Wattle)..
September/October 1999: 40 ha sprayed with Velmac G granular herbicide.
August 2001: 17.1 ha sprayed with 353.4kg of Velmac CR in order to kill 'woody weeds' in the same area that was sprayed 4 months earlier.

Hancock Watch Site Visit Apr 01: Entered the plantation from the west on Billstones Track. Drove south along Memory Square Track. Quite substantial amount of native vegetation in south west corner of plantation offering good buffer protection to trib of Shady Creek. Some older Manna Gums? in this buffer. Drove onto Memory Lane took some detours until came across some significant native vegetation along Starvation Creek including old growth trees. Headed north along Memory Lane through uncleared plantation on mild slopes.
Site visit Apr 01: This plantation lies a short drive to the north of other plantation. Drove into plantation on the Spur Track. Plantation looked like it had been harvested about 6 months earlier. Some drainage lines had non-existant buffers, however a trib to Latrobe River Creek? had decent enough buffers (although they could have been larger). The creek itself appeared to be 'protected' to a certain degree at the turn-off of Sput Track and Stanley Vale Road. Turned west onto Stanley Vale Road. Excellent buffer zone along this creek with old growth trees present. Quite a substantial area of native vegetation remains along this creek and also in the western portion of the plantation. Further harvesting of plantations was eveident on the northern side of Stanley Vale Road.
Shady Creek, Neerim - A small narrow deep creek usually providing spawning facilities for trout. Above its junction with the Moe River contains eels to 825g, river blackfish to 110g, brown trout to 550g, average 110g, and spiny freshwater crayfish.
