ALICE SPRINGS RURAL REVIEW, Page 11 of 20 Present Figure 3: Total Standing Dry Matter (TSDM) as of 31st November 2010. Future Growth Predications Figure 4: Chances of exceeding Median Growth Figure 5: Prediction Skill based on SOI Phase 2 in between December 2010 and February 2011 November 2010 Total standing dry matter (TSDM) is estimated by incorporating pasture carried over from previous season (less grazing, fire and detachment) and the current seasons growth. The TSDM map (Figure 3) indicates pasture quantity continues to vary considerably across the NT. The exceptional year across the southern NT has resulted in totals exceeding 1000kg/ha with large areas showing greater than 4000kg/ha. As expected across the northern NT for this time of year (end of the dry season), totals have fallen to generally less than 1000 to 2000kg/ha. PERSONALISED PROPERTY MAPS Are you interested in obtaining detailed AussieGRASS maps for your property? If so get in touch with Chris Materne DOR Alice Springs (89518135) chris.materne@nt.gov.au. General NT and Australia scale maps are available on line at: http://www.longpaddock.qld.gov.au/RainfallAndPastureGrowth/ Figure 4 represents the chance of exceeding median pasture growth over the coming three month period based on the SOI index. This model is predicting an extremely good chance of exceeding median pasture growth over the next three months across the majority of the NT, with the exception of the Top End. Areas around Alice Springs are starting to show a low chance of exceeding median growth for the first time this year. Low growth in these areas however may not necessarily due to reduced rainfall but may potentially be from a depletion of nitrogen reserves following the exceptional year being experienced in the district. Figure 5 shows the level of skill or confidence in these growth predictions which is generally high over the Top End but variable across the rest of the NT.
