The national feedbase imagery from the 18th of May shows the continued accumulation of biomass across the northern portion of the Northern Territory and north-west areas of Queensland.
It is evident that the drawn out wet season and milder conditions in the recent months have allowed growth to continue, which has extended to the south-east of Queensland and along the New South Wales coast.
However, Western Australia, Tasmania and parts of South Australia still lack the conditions to support meaningful biomass growth.

Total Standing Dry Matter
Image 1 – Total Standing Dry Matter (Kg/Ha)
Nationally TSDM images are dominated by the high levels of biomass across the Victoria River Downs, Barkly and Top End regions of the Northern Territory.
This accumulation extends across the gulf regions of Queensland and into the lower cape.
More broadly in Queensland and NSW, TSDM levels remain largely above 1200kg/DM/Ha.
However, across the central and western parts of the nation, TSDM levels continue to average well below 1000kg/DM/ Ha. This is also evident in sot west Victoria and into the Bass Straight islands.
Seasonal Comparison Total Standing Dry Matter

The Seasonal Ranking (based on the past 8-year average Figure 2) reflect these growth patterns, The Bass Straight islands continue to be in the lowest decile when compared to this point over the past 8 years.
Western Australia and South Australia are also considered to be largely in the lowest decile bands.
However eastern states and particularly Queensland the trend is for most regions to be above the low term average for this point in the season.
Fractional Cover (Growth)
Image 3 – Fractional Cover
Active growth events, as represented by Fractional Cover (Image 3) are largely confined to the eastern and northern areas of the continent.
High levels of soil moisture, average temperatures have combined to allow growth events to continue in these regions.
Some growth activity in the southwest of Western Australia is now noticeable and should see increases in TSDM over coming weeks.
Green Total Standing Dry Matter

Green standing dry matter levels (Image 4) replicate the growth noted in Fractional Cover.
Eastern NSW has generally average to high amounts of Green Standing Dry Matter, as does eastern, central, and northern Queensland.
Dead Standing Dry Matter
Image 5 – Dead Standing Dry Matter
Dead Standing Dry Matter imagery (Image 5) identifies areas of northern and central Queensland which now have significant bodies of dead standing dry matter.
In some areas north of Mt Isa and east of Longreach, these areas have amounts exceeding 1500kg/DM/Ha.
Further south the amounts of dead material on offer is well below 800kg/DM/Ha.
Monthly Ground Cover levels

Ground cover levels remain largely similar to previous observations with no significant alternations noted. (Image 6)
