    Weeds (suppress early Known Current Weeds are likely to be a reduced threat plant growth by competing and future at populations 1d and 1e but ongoing at for soil moisture; nutrients other sites (populations 1a; 1b; 2a; 2b and light; and increase fire and 2c).

    Grassy weeds that exacerbate the fire regime which then increases nitrification promoting further growth of weeds are a particular concern.
