for each weed type (see comments below)

for the Reserve only, for the Total Effort and for the Neighbouring paddocks only.

Reserve Only

For month by month comparisons of weeding effort against previous seasons for each weed type, see
the weed type monthly history

 

Weed type Comparative
Effort
(relative to last season)
      Likely reasons
African Lovegrass much more Last season must have been a quiet one; this season's effort is more in line with earlier seasons.
St. Johns Wort Similar
Treatment commenced on the Reserve a month later this season, largely because the dry winter and late rains resulted in a delay in growth and flowering, but has continued longer. There has been no treatment off the Reserve in the last two seasons.
Blackberries similar There are very few blackberries on the Reserve and only small ones so treatment time is small.
Briars less There are less Briars this season than in previous seasons. In addition because the first sweep was late, only one sweep has been carried out, reducing the time compared with last season.
Cootamundra wattle similar Treatment is occasional.
Saffron thistles similar The prevalence of Saffron Thistles on the Reserve started out less than previous years this season, though there were more on the Bottom Pinnacle. The summer rain caused a large increase in effort required on the Reserve.
Horehound less Horehound is decreasing in prevalence across the Reserve and neighbouring paddocks in response to treatment in previous seasons; treatment is sporadic.
Verbascum much less The prevalence of Verbascum is much less than in previous years, resulting largely from the dry summer last season (see Controls on Verbascum Prevalence).

non-Saffron thistles much less These are largely under control on the Reserve with only a few isolated occurrences at present.
Paterson's Curse less There has been little Paterson's curse in evidence so far this season as a result of the dry winter, although there has been more towards the end of the season.
Capeweed similar Prevalence was less this season than last season but a greater area of the Reserve was able to be treated than in previous seasons.
Exotic grasses (Serrated tussock, Chilean Needle grass and other exotics) more More effort to date this season on the "other" exotics.
Bathurst Burr similar Treatment occurred earlier this season than last season.
Other woody weeds similar There are very few woody weeds left in the Reserve and neighbouring paddocks. Treatment is sporadic.
Nightshade much more More nightshade this season as a result of conditions.
Miscellaneous broadleaf weeds less This category includes Hoary mustard, Prickly lettuce, fleabane, skeleton weed, flatweed, catsear, Tragopogon, etc. The amount of effort spent on these depends more on the resources available than the prevalence of the weeds. Grubbing teams this season have had few other targets.
