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 2017. Effort for previous seasons can be accessed from the menu bar above.

Total Effort


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

Between 1 July and 31 October, we spent 97 hours on weed control across the Reserve and the neighbouring paddocks. A further 19 hours was spent on experimental grass slashing for weed control. This was the smallest total for the 8 years of records for both the Reserve and the whole area managed.

The small effort reflects the lack of substantial growth of our target weeds, which in turn reflects the very dry year. For the calendar year to the end of September the rainfall is the lowest since 2008 and the 6th lowest since 1974 (see monthly rainfall summary for a comparison of the last 8 years).

 

 

 


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 October was 56 hours, slightly more than half spent on the Reserve. This represents the second smallest total October effort in the last 8 years, both for the total area and the Reserve alone.

A further 19 hours was spent on experimental grass slashing for weed control.

 

 

   

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.

Most effort has been spent in the Bottom Pinnacle, largely because the weed control over the last 8 years has been much better in the Reserve and there are few targets so far.

 

 


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.

This shows quite a different pattern but at this stage there is not enough effort for meaningful comparisons.

 

   

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 April which was all in the Reserve.

Capeweed received most effort (45%) followed by Saffron Thistles (31%) and Sweet briars (9%) with 15% of effort on other weeds combined.

 


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.

Capeweed (25 h) closely followed by Saffron Thistles (23 h) then miscellaneous Broadleaf weeds and Verbascum (both 14 h) have received the most effort. Together these accounted for 78% of the effort, with Paterson's Curse, Sweet Briars and Horehound accounting for the bulk of the remainder.

 

 


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.

Large increases in effort on Capeweed, Saffron Thistles and Briars accounted for most of the change in effort between September and October.

 

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

Comparison across the all seasons since 2010 for the four most prevalent individual weed types so far this season:

   - total effort

   - Reserve only

These graphs show that the amount of effort on the four most targeted weed types for the season to date has been within the range of previous seasons, for both the Reserve alone and the total area.

The effort for each of the four weed types shown is generally towards the bottom end of those ranges, as expected because of the dry season, with the exception of Capeweed where a greater area was treated this season that in 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.
