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 March, we spent 542 hours on weed control across the Reserve (490 h) and the neighbouring paddocks. A further 30 hours was spent on experimental slashing on the Reserve for control of introduced grasses. This was the smallest total for the 8 seasons of records for both the Reserve and the whole area managed.

The small effort partly reflects the lack of substantial growth of our target weeds early in the season, which in turn reflects the very dry year up to October. It is also affected by a significantly reduced availability of volunteer time this season.

 

 

 


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 March was 107 hours, 101 h of which was spent on the Reserve. This represents the second largest March effort in the last 8 seasons for the Reserve and the fifth largest for the total area.

 

 

   

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 Kama paddock, generally the weediest paddock on the Reserve, followed by Dam, Southern and Bottom Pinnacle 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.

This shows a somewhat different pattern with Kama still leading the way, but followed by Eastern then Southern, Dam and Forest.

 

   

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 March which was nearly all in the Reserve.

Briars received most effort (23 h) followed by Nightshade (19 h), St. John's Wort (18 h) and Verbascum (12 h). These accounted for 67% 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 and how that was distributed between the Reserve and neighbouring paddocks.

St. John's Wort (167 h), Saffron Thistles (95 h), Verbascum ( 50 h), miscellaneous Broadleaf weeds (50 h) and Briars (39 h) have received the most effort. Together these accounted for 74% of the 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.

Decreases in effort spent on St. John's Wort and Saffron Thistles from February to March were more than compensated for by increases in Briars, Verbascum and African Lovegrass.

 

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

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

   - total effort

   - Reserve only

These graphs show that the amount of effort on the most targeted weed types for the season to date for the Reserve alone and the total area.

The effort for St. John's Wort, Saffron Thistles and Briars were in the range of previous seasons and similar to last season. For Verbascum and Miscellaneous Broadleaf Weeds it was the smallest of the 8 seasons of records for the total area and for the Reserve alone. In the case of Verbascum this was because there was very little Verbascum this season as a result of the low rainfall in the previous summer (see Controls on Verbascum Prevalence for an explanation) while for Broadleafs it was mainly the result of a lack of volunteer availability.

 

Comparison of monthly effort for each weed type for the last eight 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 and Verbascum being prime examples).

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.
