An important aspect of the Weed Management Plan is monitoring and reporting on our interventions. This includes monitoring our weeding effort to know how our resources have been deployed, and to compare it with the requirements projected in the plan and effort in previous seasons.

Regularly updated (monthly) weeding effort data are displayed on this page. The data is accumulated from 1 July 2020. Effort for previous seasons can be accessed from the menu bar below.

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 January the total amount of effort spent on weed control was 477 hours, entirely within the Reserve (including the Extension). This was 87% more than last season but the fourth smallest total effort in the 11 seasons of records and the second largest for the Reserve alone. Comparing with effort on the Reserve alone it was the fifth smallest.

The increase in effort compared with last season reflects the fact that 2020 was the fifth wettest year in the 47 years since BoM rainfall records commenced in this area, and the wettest since 2016. It was also a warmer than average winter. Ideal conditions for germination and growth of the many weed types present on the Reserve. It should be noted that it was also ideal conditions for native species which have been present in abundance, with many species being observed for the first time in many years.

Unfortunately the effort has not been sufficient (because of reduced capacity) to deliver the same level of control as in previous seasons.

 


The chart shows the total effort for the most recent month each for all seasons, divided into the time spent in the Reserve, Bottom Pinnacle and North Kama paddocks.

The total effort for January was 95 hours, all on the Reserve. This was the second smallest in our 11 seasons of records (fourth smallest for the Reserve alone), but 560% larger than last season, when weed control was restricted by the OH&S rules about working with high levels of smoke in the air, as well as fire bans.

 

 

 

   

Effort in different 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, separated into the time spent applying each weed control method.

It can be seen that Weetangera has received the greatest effort by far, accounting for 42% of the effort. Southern, Central and Kama paddocks accounted for another 42% of effort.

 

 


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

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

On this basis, Weetangera remains clearly the largest, followed by Kama, Southern, the Forest and Central paddocks.

 

   

Effort for different weed types


The chart shows the effort for each for the most recent month, divided into the time spent in the Reserve, Bottom Pinnacle and North Kama paddocks.

... for the most recent month

The main targets for the month were Saffron Thistles (32 h), Miscellaneous Broadleaf weeds (24 h), Verbascum (21 h) and St. John's Wort(10 h), which together comprised 91% of the month's effort.

 


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.

The collection of uncategorised broadleaf weeds (which incudes Hoary Mustard, Prickly Lettuce, Nightshade, Plantain, Flatweeds, Paddymelon and Sorrel) have received the most effort (142 h) followed by Saffron Thistles (85 h), Verbascum (64 h) and Capeweed (60 h), together comprising 68% of the effort. Exotic grasses (42 h), St. John's Wort (35 h), Thistles other than Saffron Thistles (27 h) and Paterson's Curse (16 h) were next, together accounting for another 25% of total effort.

 

 


This chart shows the change from month to month of weeding effort for the different weed targets.

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. The big changes between December and January were increases in effort on Saffron Thistles, miscellaneous broadleaf weeds and African Lovegrass and a decrease in Exotic grasses.

 

Other ways to view and compare the effort for different weed types

Comparison across the last 11 seasons for the four most prevalent weed types so far this season:

This shows that the collection of uncategorised broadleaf weeds and Capeweed received more effort than ever before for the first 7 months of the season. Effort for Saffron thistles and Verbascum were within the range of previous seasons.

 

Comparison of monthly effort for each weed type for the last six seasons and for all months of the season

weed type monthly history

This is a useful set of graphs that show how the effort spent on each weed type in each month over the past four seasons has changed. In some cases it has increased or decreased vastly from season to season, as the prevalence of different weed types has changed from season to season (Saffron thistles being a prime example).

For all weed types, though, these charts provide a guide of what is likely to be expected in coming months for each type based on previous experience.

 

Comparison of total effort for each weed type for the season to date for the last five seasons

season to date weed type comparisons

This series of charts provides a comparison, as the season progresses, of the total weeding effort to date for each weed type compared with previous seasons. At the end of the season they provide a good summary of the season's weed prevalence compared with previous seasons.

Charts are available for total effort, for effort just on the Reserve, and for effort just in the neighbouring paddocks.

 

Relative prevalence of each weed type in each paddock

weed types in each paddock

This shows, for each paddock, the effort that has been spent in the season to date on each weed type by hovering your mouse over a paddock map.

 

Relative prevalence in each paddock of each weed type

effort per hectare in each paddock for each weed type targeted

This shows, for each weed type, the effort that has been spent in the season to date in each paddock. Its 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 total effort in each paddock for each weed type by following a separate link on the page referred to above.
