She found that barberry tissue is high in nitrogen-rich compounds akaloids, which causes a loss of organic matter in nearby soil due to excessive nitrogen cycling. As barberry starts to decompose, the nitrate levels in nearby soil start to increase, making the areas susceptible to weeds. Ehrenfeld removed barberry in the
