Summary
La Niña in all its glory revitalised the drought-stricken Bogan Local Control Authority (LCA), from dust storms to good rain, good vegetative growth of native species and the dreaded weed.
With above average rainfall in the previous 4 years and a return to normal seasonal conditions over the spring and summer plant growth increased with pasture growth aiding as perfect cover and as such made it hard to spot invasive infestations. With the return to average conditions (hot and dry) this task became easier to spot country and western weeds.
This paper delves into those weeds that enjoyed the above average conditions where numbers proliferated to those that don’t mind unforgiving conditions and continue too try and dominate in the specific areas where conditions (soil, topography) favour their spread.
It is not just those “introduced invasive species” that a weeds officer needs to have knowledge about, but also understand introduced non-invasive species and native species that are considered a pest species by some.
