Comparison of effort in 2021-22 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 slightly more Greater prevalence this season
St. John's Wort much more
It is generally agreed that is is the worst year for St. John's Wort for many years, and the effort to date reflects that. Despite this large effort we have treated less than 50% of the St. John's Wort on the reserve.
Blackberries much more It is a good season for blackberries to germinate and grow rapidly.
Briars more As above, conditions have been very good for germination and growth of briars.
Cootamundra wattle similar There are not many on the Reserve and treatment is occasional.
Saffron thistles much less Much reduced number of Saffron thistles this season
Horehound much less Horehound is decreasing in prevalence across the Reserve in response to treatment in previous seasons; treatment is sporadic.
Verbascum slightly more Verbascum is much more prevalent this season than for many years as a result of two very wet seasons but we have been unable to treat it all.
non-Saffron thistles much more Although these have been largely under control on the Reserve, the wet season has caused their resurgence.
Paterson's Curse much less Paterson's Curse is not yet present in significant numbers this season.
Capeweed much less Effort has been much less than last season (when considerable effort was expended in an attempt to control it in Weetangera paddock) but about about the same as previous seasons.
Exotic grasses (Serrated tussock, Chilean Needle grass and other exotics) much less Not much effort on grasses this season.
Bathurst Burr more Treatment that would normally have been done at the end of last season was carried over to the beginning of this one.
Other woody weeds much more There are very few woody weeds left in the Reserve and neighbouring paddocks. Treatment is sporadic, but this season had een very favourable for their growth..
Skeleton weed much less Skeleton weed has not been specifically targeted so far this season.
Miscellaneous broadleaf weeds much less This category includes a range of low to medium risk weeds such as Hoary mustard, Prickly lettuce, fleabane, flatweed, catsear, Tragopogon, plantain, etc. Effort has been directed to other weeds.
