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 less Effort confined to critical areas inside the Reserve this season.
St. Johns Wort similar Treatment only commenced in the last few days of November this season, compared with October in previous seasons.
Blackberries less Treatment has not commenced on the Reserve yet this season.
Briars same Treatment has not commenced on the Reserve yet this season, although some time was spent in the neighbouring paddocks.
Cootamundra wattle same Treatment is occasional.
Saffron thistles similar (Reserve)
much less (Total)
The prevalence of Saffron Thistles on The Reserve started out less than previous years this season, though there were more on the Bottom Pinnacle. Recent rain is expected to cause a large increase in effort required on the Reserve.
Horehound more 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 Like many other weed types this season, prevalence is low as a result of the very dry winter and spring.
Paterson's Curse less There has been little Paterson's curse in evidence so far this season as a result of the dry winter.
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   No effort to date this season.
Other woody weeds much less There are very few woody weeds left in the Reserve and neighbouring paddocks. Treatment is sporadic.
Nightshade about the same  
Miscellaneous broadleaf weeds more 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.
