Comparison of monthly weeding effort by:
weed species, paddock and control method
Weed species treated each month between July 2010 and June 2011
This graph shows how the relative effort required for different species and the total effort changed monthly across the year. It clearly indicates the big surge in effort required across late spring and summer to control Saffron Thistles and St Johns Wort, whereas effort for many other species is distributed throughout the year, lessening in summer because of the demands to control the seasonal species.
Paddocks treated each month between July 2010 and June 2011
This graph shows how the relative effort required in each paddock changes across the year. The large peak in the Kama paddock in summer reflects the intense infestation of Saffron thistles in this paddock requiring treatment at that time.
Weed control methods used each month between July 2010 and June 2011
This graph shows how the relative effort expended in different weed control methods changes across the year. Grubbing is spread throughout the year, slashing and scything peak in summer to control the Saffron thistles, bagging of seed heads occurs largely in autumn to treat weeds that were not controlled before seed maturity, and spraying is consistent through the warmer months.
