what's on news

 

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 2018. 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 431 hours, 99% within the Reserve (including the Extension). This was 27% more than the total for this period last season and 41% more than the effort on the Reserve alone last season.

A further 151 h was spent on rescuing Themeda (kangaroo grass) from the route of the new Molonglo pipeline and transplanting it to a degraded patch of the Weetangera paddock as well as an additional 11 h spent on weed mapping.

 

 

 

 


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

In January the total was 108 hours, 100% spent on the Reserve. This represents the second lowest total January effort in the last 9 seasons, third lowest on the Reserve alone.

This was 10% more than the previous January, primarily because of volunteer availability.

 

   

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 followed by Dam, Central, Kama and Southern 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 weed prevalence between paddocks is to express the effort as hours per hectare.

On this basis, Weetangera maintains its clear dominance with Kama, Dam and Central all following closely behind.

 

   

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 chart to the left shows the effort for each weed type for January and whether it was spent on the Reserve or on neighbouring paddocks.

Clearly St. John's Wort received the bulk of the effort (58 h; 52%) followed by miscellaneous Broadleaf weeds and African Lovegrass (with all other weed types receiving less than 6 hours).

 


 


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 and how that was distributed between the Reserve and neighbouring paddocks.

 

St. John's Wort has also received the most effort so far for the season to date (156 h), followed by the group of uncategorised broadleaf weeds (89 h), Skeleton weed (41 h), Exotic grasses (excluding African Lovegrass (27 h) and Saffron Thistles (25 h). Together these account for 78% of the effort so far this season.


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. As expected from the preceding charts and discussion the main change from December to January was an increase in effort on St. John's Wort, African Lovegrass and Briars and a decrease in effort on Saffron Thistles, Paterson's Curse and other Exotic Grasses, resulting in a similar total for the two months.

 

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

Comparison across the last six seasons for the five most prevalent weed types so far this season:

   - total effort

   - Reserve only

These graphs show that the amount of effort on St. John's Wort and miscellaneous Broadleaf weeds were within the range of previous seasons, with less effort spent on Saffron Thistles than in previous seasons (despite early indications that they would be widespread this season).

Skeleton Weed which has not been specifically targeted in previous seasons.

More effort was spent on Exotic grasses than in previous seasons because of the availability of time to focus on them with the dry winter reducing the number of the usual weed targets. For a similar reason the list of most targeted weed types for the season to date is also quite different to normal, except for St. John's Wort.

 

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.
