Weeds are recognised as a primary constraint on crop production , rangelands  and forests . Climate change could favour the growth and development of weeds over crops with negative consequences for desired plants in managed systems  . First, changes in temperature and precipitation alter the range, composition and competitiveness of native and invasive weeds . Second, rising concentrations of CO2 enhance growth of C3 species  , and increase plant water use efficiency with potentially strong effects on invasive plant species establishment .
