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; Reserve only)
      Likely reasons
African Lovegrass much less Minimal African Lovegrass observed so far this season
St. Johns Wort much more
Treatment started a month earlier than last season. Effort is similar to earlier seasons.
Blackberries same  
Briars same  
Cootamundra wattle similar Treatment is occasional.
Saffron thistles less The dry winter reduced their emergence, but germination after recent rains are likely to result in increased effort.
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 Very little Verbascum this season.
non-Saffron thistles similar These are largely under control on the Reserve with only a few isolated occurrences at present.
Paterson's Curse less Conditions this season have favoured Paterson's curse ahead of other weeds.
Capeweed much less Prevalence is much less this season than last season because of the dry winter and spring.
Exotic grasses (Serrated tussock, Chilean Needle grass and other exotics) much more More effort to date this season on the exotic grasses such as oats, particularly in Weetangera paddock where there is an increased effort to control them after the hazard reduction burn early in 2018.
Bathurst Burr same There is very little Bathurst Burr and it is not treated until Autumn.
Other woody weeds much more There are very few woody weeds left in the Reserve and neighbouring paddocks. Treatment is sporadic.
Skeleton weed   Skeleton weed treatment not monitored in the past.
Miscellaneous broadleaf weeds much more This category includes Hoary mustard, Prickly lettuce, fleabane, 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.
