Treatment elements
Action
1300m diversion bank and level sill outlet on ridgeline completed January 2018
Nominal 35ha project area around the diversion bank and gully system part of planned rotational grazing of 1200ha and later 340ha paddock ( including approx . 18.5 ha of diversion bank sub-catchment ripped and reseeded )
Activity
Successfully reseeded and stabilised following 100mm storm after construction . Some channel damage and level sill required maintenance January 2020 . Within the grazing program for the 1200ha and later 340ha paddock .
Part of planned grazing practices for the surrounding paddock with graze periods up to two months and long recovery periods - examples :
• limited grazing in 2018 to allow stabilisation of works ;
• 2500 head for three weeks late summer 2019
• 2000 head four weeks November 2019 ;
• 1000 head during wet season 2020 ;
• heavily-grazed at end of dry season 2020 then subdivided into 340ha paddock 2021 ; and
Nominal project area 35ha
• short-duration rotational grazes by 480 cows and calves end March and July 2021 and then during 2021-22 wet season .
The landholder constructed a stock water dam within the gully at the end of the nominal project area ( however , flooding one of the DAF monitoring sites ).
In Jan 2020 , new manager misunderstands instructions and directs dozer to level secondary head cut and control gully . Disturbed areas reseeded and continued as part of a planned grazing program .
