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
Effort
(relative to last season; Reserve only)
      Likely reasons
African Lovegrass much less Control has not yet commenced for the season.
St. Johns Wort much less
Control has not yet commenced for the season.
Blackberries similar Control has not yet commenced for the season.
Briars similar Control has not yet commenced for the season.
Cootamundra wattle similar There are not many on the Reserve and treatment is occasional.
Saffron thistles more The wet autumn and winter stimulated more germination and emergence than the previous 3 years.
Horehound much less Horehound is decreasing in prevalence across the Reserve in response to treatment in previous seasons; treatment is sporadic.
Verbascum much less Control has not yet commenced for the season.
non-Saffron thistles much more These have been largely under control on the Reserve but the autumn and winter rain has caused their resurgence.
Paterson's Curse similar 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 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 This is largely the extra effort to control exotic grasses around the revegetation areas in Weetangera paddock.
Bathurst Burr similar Bathurst Burr does not usually appear until much 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.
