“…(Sale and Wetzel 1983). However, Sharma and Kushwaha (1990) conducted three successive cuttings of shoots at 5 cm above the water level and reduced the below-ground biomass of T. angustata by 75%, which confirmed the effectiveness of above-water cutting at sites with shallow or varying water depths.…”

“…However, the process is related to the soil oxygen concentration and it is sometimes difficult to maintain the water level. Subsequently, the effectiveness of above-water cutting was confirmed (Sharma and Kushwaha 1990). In this study, we evaluated the effectiveness quantitatively by considering the timing and the rate of flowering shoots with 3 years of experiments and provided an analytical background for the mechanism.…”

“…These studies indicate the importance of the timing of cutting, especially during the flowering season (Singh et al 1976;Husa´k 1978), the number of cuttings per year (Ulrich and Burton 1985;Sharma and Kushwaha 1990) and the water depth over the cut stems (Beule 1979) to control of excessive growth of Typha spp. The mechanism of biomass reduction is related to the consumption of the rhizome storage in these plants.…”

Management of below-ground biomass of Typha angustifolia by harvesting shoots above the water surface on different summer days

et al. 2005

A dynamic model of regrowth in Typha angustifolia after cutting shoots above the water surface was formulated by characterizing the phenology and mobilization of resources from below-ground to aboveground organs after the cutting. The model parameters were determined by two cutting experiments to investigate the different strategies with flowering and nonflowering shoots after cutting in 2001 and by four cutting experiments to elucidate the regrowth characteristics after cutting on different days from June to September in 2002. A difference was evident both for flowering and non-flowering shoots and for each cutting day. From June to August, non-flowering shoots regrew immediately after cutting, but flowering shoots did not. The shoot regrowth height, number of leaves and shoot biomass were higher with the earlier cutting. The model was validated using the below-ground biomass observed in December 2002 and below-ground dynamics observed in 2003. In the low-flowering shoot zone of the stands, in which the percentage of flowering shoots was small (around 10%), the decrease in below-ground biomass became larger from June (20%) to August (60%). Cutting the high-flowering shoot zone (flowering shoots: 78%) in July 2001, just 1 week after peduncle formation, decreased the below-ground biomass by about 50%. In the low-flowering shoot zone, cutting just before senescence is better for decreasing below-ground biomass with a smaller rate of flowering shoots. The difference of below-ground biomass reduction in non-flowering shoots is mainly due to the decrease in downward translocation (DWT) of above-ground material to below-ground organs during senescence, because of the decrease in regrowth biomass. As for flowering shoots, the decrease in the photosynthate transportation from above-ground to below-ground organs and that of DWT are closely related because they cannot grow again within the season.

AimTypha latifolia causes serious problems in wet meadows by overgrowing and suppressing other native plants. To determine suitable management for T. latifolia control, we addressed the following question: What are the effects of long‐term cutting at different frequencies (once or twice per year and no management) and biomass removal on cover and other characteristics of T. latifolia, and on sward productivity and plant species composition?LocationMalá Strana nature reserve, Jizerské hory Mountains, Czechia.MethodsA long‐term experiment arranged in a randomised block design with three blocks was established in 2005. Data were collected from five treatments: unmanaged control; cutting once a year in June without biomass removal and with biomass removal; cutting twice per year in June and August without biomass removal and with biomass removal. Percentage cover of T. latifolia and other vascular plant species was visually estimated and T. latifolia characteristics (tiller density, height, dry‐matter biomass [DMB] yield and litter), sward height and DMB yield were measured during 2005–2018 at the end of June.Results and DiscussionRegular cutting once or twice per year regardless of cut biomass removal led to reductions in tiller density, height, litter and DMB yield of T. latifolia. Biomass removal had only a slight tendency to affect T. latifolia characteristics. The higher frequency of cutting significantly decreased the mean T. latifolia cover, litter and DMB yield. Cutting once or twice per year regardless of biomass removal led to successive changes in plant species composition but had no effect on the species richness and evenness.ConclusionsCutting at least once per year without biomass removal seems to be sufficient to achieve a decrease in DMB yield and litter of T. latifolia plants, and thereby maintain the wet‐meadow vegetation without loss of species richness and also preventing the overgrowth of shrubs and trees.
