Total Effort

The chart shows the total effort for each of the last six seasons, divided into the time spent in the Reserve, Bottom Pinnacle and North Kama paddocks.

Between 1 July 2023 and 31 July 2024 the total amount of effort spent on weed control was 869 hours, 98% within the Reserve. The small amount of effort outside the Reserve was aimed at creating buffer zones around the boundaries.

This was 13% less than last season and 2% less than the average for the previous 13 seasons of monitoring. If Weetangera paddock is excluded from calculations (as explained below *) effort for the rest of the Reserve was 24% less than the average for the previous 13 seasons.

This decrease relative to last seasons is attributed to weather conditions.

* Note that data for Weetangera paddock is separated from the rest of the Reserve in this and some of the charts below because of the disproportionate amount of effort there in recent seasons with a large proportion of that effort being very intensive, associated with preparing and maintaining planting sites.

Total effort in different management areas (paddocks)

The chart shows the total effort for each paddock, divided into the time spent using different weed control methods.

This chart shows the effort for the season to date in each paddock (see paddock map), separated into the time spent applying each weed control method.

It can be seen that Weetangera paddock received the greatest effort (312 h, 37% of the total Reserve effort), followed by Kama Link, Dam, Eastern, Southern and Central, with less than 40 h effort in each of the other paddocks.

The chart shows the total effort per ha for each paddock.

The areas of the paddocks differ considerably, so a better way to compare weeding effort (and to some extent weed prevalence) between paddocks is to express the effort as hours per hectare.

On this basis, Weetangera paddock retains the top spot while Eastern jumps to second followed by Kama Link, Dam, Hawker, Southern, Central, Kama and the Forest.

Weetangera paddock (23.6 h/ha) received more than six times the effort of the rest of the Reserve (3.8 h/ha).

Total effort for different weed types

This chart shows the effort for each weed type across all paddocks for the season to date.

... for the season to date

This chart shows the total effort for the season so far for each weed type.

Most effort (303 h; 36% of total) was spent in this period on the group of uncategorised low to medium risk broadleaf weeds* largely in Weetangera paddock. This was followed at a distance by St. John's Wort (166 h, 19%), Woody weeds excluding Briars and Blackberries (91 h, 11%) Paterson's curse (78 h, 9%) largely in Kama Link paddock and Thistles other than Saffron thistles (58 h, 7%). All other weeds combined accounted for 20% of effort.

*this incudes Hoary Mustard, Prickly Lettuce, Nightshade, Fleabane, Tragopogon, Plantain, Flatweeds, Paddymelon and Sorrel.

This chart shows the effort for each weed type for each month of the season to date.

... for each month so far this season

The chart to the left summarises the effort for the different weed types for each month this season, showing how the effort on different weed types changed from month to month.

Effort on miscellaneous Broadleaf weeds and Paterson's curse was comparatively uniformly distributed across the months while that on St. John's Wort ramped up in December and January as spraying season got underway and effort on thistles was greatest in late summer early autumn.

It is also worth comparing this chart with those for all previous seasons (from which it can be seen that February 2024 was our busiest month for several years).

Hover your mouse pointer over any paddock to see the effort that has been spent in that paddock in this season on each weed type.

This shows, for each weed type, the effort that has been spent in the season to date in each paddock.

Effort is expressed per hectare to take into account the different paddock sizes. This allows one to judge relative levels of infestation by each weed type in different paddocks.

The data can be also viewed as hours of effort in each paddock for each weed type.
