  1. Cut/mow herbaceous plants to maintain or restore disturbance: freshwater marshes

    A replicated, controlled study in 2005 in a freshwater marsh in southern Brazil (Silveira et al. 2012) reported that cutting southern cattail Typha domingensis reduced its density and biomass for <60 days. After 1–26 days, cut plots contained fewer mature cattail stems than uncut plots (cut: 05; uncut: 1944 stems/m2) and less above-ground cattail biomass (cut: 50–70; uncut: 350–470 g/m2). After 60–182 days, cut and uncut plots contained a statistically similar number of mature stems (cut: 1623; uncut: 1629 stems/m2) and above-ground biomass (cut: 230420; uncut: 300–440 g/m2). The density of young stems and dead stems never significantly differed between cut and uncut plots (see original paper for data). Methods: In June 2005, eight 1-m2 plots were established in a dense stand of southern cattail. Four plots were cut. Cuttings were removed. Four plots were left uncut. All cattail stems (mature: >80 cm tall; young: <80 cm tall; dead) were counted and measured in each plot until December 2005. Dry, above-ground biomass was estimated from stem heights.
