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 2016. Effort for previous seasons can be accessed from the menu bar above.

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 30 April, we spent 711 hours on weed control across the Reserve and the neighbouring paddocks. A further 19 hours was spent on experimental grass slashing for weed control. Excluding the experiment effort, this was 36% (399 h) less than last season, and the smallest total for the 7 years of records. The amount of time spent on the Reserve itself was only 21% less than last season, but also the smallest on record. This reflects a large decrease in available volunteer time as well as the effect of the extremely dry summer on weed growth this season.

 

 

 


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.

The total effort for April was 65 hours, all of which was spent on the Reserve. This represents the second smallest total April effort in the last 7 years, and the third smallest for the total and for the Reserve alone.

A large part of the reason for this is that after the driest summer in 15 years there is not a large quantity of viable weed targets now that those generated by the winter rainfall have been dealt with.

 

 

   

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.

The largest effort has been spent in Kama paddock, consistently the paddock requiring the most effort to control the major weeds. This was followed by Dam, Southern and Central.

Spraying was the dominant control method we have used (53% of effort - 375 h).

 

 


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.

Eastern received the largest effort per ha because of it's small area and a disproportionate amount of effort being spent there grubbing miscellaneous broadleaf weeds. Kama, Southern, Dam and Central followed.

 

   

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.

Verbascum received most effort (37%) followed by Miscellaneous broadleaf weeds (22%), St. John's Wort (19%), and Briars (18%).

 


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 (202 hours), Verbascum (139 h) and Saffron thistles (99 h) and have accounted for 62% of the effort, with another 21% from Briars and miscellaneous Broadleaf weeds.

 

 

 


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 increase in total effort for the month was the result mainly of an increase in effort on Briars, Verbascum and miscellaneous Broadleaf weeds.

 

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

Comparison across the last six seasons 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.

Looking at the Reserve alone (where our effort has been largely confined because of reduced capacity) the effort for each of the four weed types shown is within the ranges for previous seasons and, except that for St. John's Wort which slightly exceeded the largest amount of effort 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.
