Comparison of effort in 2020-21 with earlier seasons

for each weed type (see comments below)

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

Reserve Only


Weed type Comparative
(relative to last season; Reserve only)
      Likely reasons
African Lovegrass similar
St. Johns Wort slightly less

Blackberries similar  
Briars similar  
Cootamundra wattle similar There are not many on the Reserve and treatment is occasional.
Saffron thistles much more The wet autumn and winter stimulated more germination and emergence than the previous 4 seasons.
Horehound much less Horehound is decreasing in prevalence across the Reserve in response to treatment in previous seasons; treatment is sporadic.
Verbascum considerably more Vebascum is much more prevalent this season than for many years as a result of the very wet season. 2015-16 (also wet) was the last season with more effort on Verbascum than this season.
non-Saffron thistles more These have been largely under control on the Reserve but the wet season has caused their resurgence.
Paterson's Curse much less Despite the resurgence in numbers caused by the favourable autumn weather, control at the end of last season seems to have paid off in keeping its prevalence relatively low since July.
Capeweed much more Effort was much more because of the autumn and winter weather conditions causing earlier germination and growth in quantities many times what we normally experience.
Exotic grasses (Serrated tussock, Chilean Needle grass and other exotics) much more 97% of this effort was spent in controlling exotic grasses in and around the revegetation areas in Weetangera paddock. Note that most effort was spent on grasses with a low risk'; effort required on the high risk species was similar to previous seasons.
Bathurst Burr similar Bathurst Burr does not usually appear until later in the season.
Other woody weeds similar There are very few woody weeds left in the Reserve and neighbouring paddocks. Treatment is sporadic.
Skeleton weed much less Skeleton weed has not been specifically targeted so far this season.
Miscellaneous broadleaf weeds much more This category includes Hoary mustard, Prickly lettuce, fleabane, flatweed, catsear, Tragopogon, plantain, etc. The wet autumn and winter stimulated more germination and emergence of most of these weeds than in previous years. Note that nearly 60% of this effort was in Weetangera paddock in and around revegetation areas.
