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

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 This is attributed to reduced grass activity in the hot, dry conditions.
St. Johns Wort much less
The amount of St. John's Wort is much less than last season because of the hot, dry conditions.
Blackberries similar Treatment is only partially completed so far this season.
Briars slightly less There have been less briars to deal with so far this season.
Cootamundra wattle similar There are not many on the Reserve and treatment is occasional.
Saffron thistles much less The dry winter and continued hot, dry conditions have reduced their emergence and growth.
Horehound much less Horehound is decreasing in prevalence across the Reserve in response to treatment in previous seasons; treatment is sporadic.
Verbascum much less There is very little Verbascum this season, which was also the case last season. It is hoped that this reflects successful control rather than seasonal weather conditions.
non-Saffron thistles similar These are largely under control on the Reserve with only a few isolated occurrences at present. They become more obvious in dry conditions.
Paterson's Curse much more Paterson's Curse seems to be better suited to the dry conditions this season that many other weeds.
Capeweed slightly more Prevalence was similar to last season.
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.
Bathurst Burr similar Bathurst Burr doesn't usually show up until late in the season.
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.
