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 and 31 March the total amount of effort spent on weed control was 781 hours, 98% within the Reserve. Effort outside the Reserve was aimed at creating buffer zones around the boundaries.

This was 39% more than last season (which was impacted by an extended period of lockdown due to Covid-19) but 5% below the average for the previous 12 seasons of monitoring. If Weetangera paddock is excluded from calculations (as described below *) effort for the rest of the Reserve was 18% below the average for the previous 12 seasons.

* 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, followed by Southern, Kama Link, Dam and Kama paddocks, with less than 50 h effort in each of the other paddocks.

The large amount of effort in Weetangera paddock was associated with the intensive preparation of patches for planting and follow-up weed removal in those areas.

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, Eastern jumps to second spot followed by Southern, and Kama Link.

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 (218 h; 28%) was spent in this period on St. John's Wort. This was closely followed by the group of uncategorised low to medium risk broadleaf weeds* (213 h, 27%) primarily in Weetangera paddock. Thistles (113 h, 14%), Exotic grasses other than those classified as being of National Significance (81 h, 10%) and Verbascum (77 h; 8%) were the only other weeds receiving significant effort. All other weeds combined accounted for <10% 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 so far this season, showing how the effort on different weed types changed from month to month.

Note the lull in activity in September and October following a busy July and August catching up on last season's weed control and before swinging into action on St. John's Wort in November. It can also be seen that the total monthly effort has remained constant since November.

It is also worth comparing this chart with those for all previous seasons.

Hover your mouse pointer over any paddock to see the effort that has been spent in that paddock in the season to date 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.
