| Weed type
| Comparative
Effort
(relative to last season; Reserve only)
| Likely reasons
|
| African Lovegrass
| similar
| |
| St. Johns Wort |
much less
|
Reduced capacity and wet weather has reduced the effort, along with the lasting effects of the autumn spraying carried out for the first time.
|
| Blackberries |
similar |
Control has not yet commenced for the season. |
| Briars |
much less |
Control has not yet commenced for the season. |
| 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 |
much more |
Vebascum is much more prevalent this season than for many years as a result of the wet year.
|
| 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 |
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 |
This is largely the extra effort to control exotic grasses around the revegetation areas in Weetangera paddock. Growth of exotic grasses is greater than in many previous seasons. |
| Bathurst Burr |
similar |
Bathurst Burr does not usually appear until later 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 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. |
