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 2021. 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 March the total amount of effort spent on weed control was 560 hours, entirely within the Reserve. This was 14% less than last season but around the average of the last 6 seasons.

This reflects the counter-balancing effects of 2021 being the wettest year so far since 2010 (indeed the wettest year in the 51 years of official records in this part of Belconnen), offset by the restrictions associated with the Covid-19 lockdown preventing ParkCare activity and the reduced number of weeding volunteers.

Note that data for Weetangera paddock is separated from the rest of the Reserve in this and some of the charts below because of the disproportionate amount of effort there in recent years and the different character of that effort.


Total effort in different management areas (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 paddock has received the greatest effort, followed by Dam, Kama Link, Southern, Kama, the Forest, Central and Hawker paddocks, with less than 20 h effort in each of the other 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 weeding effort (and to some extent weed prevalence) between paddocks is to express the effort as hours per hectare.

On this basis, Weetangera paddock retains the top spot but most other paddocks change order; Eastern jumps to second spot and Forest to third, followed by Dam, Kama and Kama Link (all three receiving 3.3 h/ha) and then Southern. Apart from Weetangera, where weeding effort is concentrated intensively in planting sites, the order reflects our current weeding priority areas.


Total effort for different weed types

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.

St. John's Wort continues to receive the most effort (228 h; 41%), it being our most most prevalent high risk invasive weed. Verbascum is next (107 h; 19%) followed by the collection of uncategorised low to medium risk broadleaf weeds (which incudes Hoary Mustard, Prickly Lettuce, Nightshade, Tragopogon, Plantain, Flatweeds, Paddymelon and Sorrel; 67 h, 12%; primarily in Weetangera paddock), then non-Saffron thistles (65 h) with the rest accounting for 16% of the effort.


This chart shows the effort for each weed type for each month of the season to date.

... for each month so far this season

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 dip in August and September were the result of Covid-19 lockdown restrictions, with a big rebound in October as restrictions eased.

Note the dominance of Verbascum in the first 4 months (as we caught up with unfinished control from last season), then St. John's Wort from November to February as we put maximum effort into that, followed by a shift of some of that effort to Briars and Verbascum in March.

It is also worth comparing this chart with those for all previous seasons.

... relative effort

This shows, for each weed type, the effort that has been spent in the season to date in each paddock.

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 hours of effort in each paddock for each weed type.
