Comparison of effort in 2019-20 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 much less This is attributed to reduced grass activity in the hot, dry conditions although since early March it has been flourishing again outside the Reserve but not so much inside.
St. Johns Wort much less
The amount of St. John's Wort was much less in spring than last season because of the hot, dry conditions. Although the wet late summer stimulated more growth than normal, spraying it took less time than normal.
Blackberries similar Treatment is only partially completed so far this season.
Briars less There have been less briars to deal with so far this season. Also, there was not time available for a second sweep in Bottom Pinnacle.
Cootamundra wattle similar There are not many on the Reserve and treatment is occasional.
Saffron thistles much more The dry winter and continued hot, dry conditions reduced their emergence and growth in spring. The late summer rain has stimulated a resurgence that result in increased effort in May/June.
Horehound much less Horehound is decreasing in prevalence across the Reserve in response to treatment in previous seasons; treatment is sporadic.
Verbascum similar There was very little Verbascum in spring, which was also the case last season. It is hoped that this reflects successful control rather than seasonal weather conditions. There was increased prevalence as a result of the late summer rainfall but so far has been in isolated pockets able to be targeted fro past experience resulting in moderate effort required.
non-Saffron thistles similar much more These have been largely under control on the Reserve but the late summer rain caused their resurgence, although still in smaller numbers than a few years ago.
Paterson's Curse much more Paterson's Curse seemed to be better suited to the dry conditions this season that many other weeds and grew prolifically following the late summer rainfall. It has required more effort than any other season except 2013-14.
Capeweed much more Effort was much more than last season but similar to previous seasons; unfortunately it was not sufficient for adequate control.
Exotic grasses (Serrated tussock, Chilean Needle grass and other exotics) much less The dry season seems to have reduced the prevalence of the target species in this grouping. They do not seem to have been as competitive following the summer rain as other species.
Bathurst Burr much less Bathurst Burr responded well to the summer rain and occurred in laces we haven't found it before, but we caught it while small so that it has resulted in less effort.
Other woody weeds less There are very few woody weeds left in the Reserve and neighbouring paddocks. Treatment is sporadic.
Skeleton weed much less Skeleton weed treatment has only been monitored since last season when a concerted effort was spent on it. It has received less attention this season so far.
Miscellaneous broadleaf weeds similar This category includes Hoary mustard, Prickly lettuce, fleabane, flatweed, catsear, Tragopogon, plantain, 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.



Total Effort (Reserve plus Bottom Pinnacle plus North Kama)


Bottom Pinnacle and North Kama only
