Total Effort |
|
|
Between 1 July 2026 and 30 September 2027 the total amount of effort spent on weed control was 178 hours, 88% within the Reserve*. This was 20% less than last season and 37% more than the average for the previous 16 seasons of monitoring. When Weetangera paddock is excluded from calculations (as explained below **) effort for the rest of the Reserve was 22% more than last season and 29% more than the average for the previous 16 seasons.
* the small amount of effort outside the Reserve was aimed at creating buffer zones around the boundaries.
** 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.
Weetangera and Kama Link paddocks received the greatest total effort, followed by Dam, North Kama Home, Central, Hawker, North Kama Home Northwest and Eastern.
This chart also shows the distribution of spraying effort. The limited amount of spraying time we have is primarily directed to paddocks with areas having the greatest density and diversity of native plant species. The exception is the spraying effort in Bottom Pinnacle to control key weed species in a buffer zone along the Reserve boundary.

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.
For this period the order chnages very little.

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
This chart shows the total effort for the season so far for each weed type, separated into different parts of our treatment area as described below.
Most effort (37 h; 21% of total) was spent on Paterson's curse, closely followed by Capeweed (32 h; 18%, largely in Weetangera paddock). These were followed by the group of uncategorised low to medium risk broadleaf weeds*, also largely in Weetangera paddock (25 h, 14%) then Verbascum (23 h; 13%, largely in North Kama), Saffron thistles (18 h, 10%), Other thistles (16 h, 9%) and Mustard (15 h; 9%). All other weeds combined accounted for less than 10% of effort.
*this incudes 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
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.
It is also worth comparing this chart with those for all previous seasons.

... relative effort
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. |
