“…Based on our results, we recommend large scale testing of Typha harvesting ± disking (to disrupt rhizomes) in the field under different hydrologic conditions to control this aggressive invader. Harvested Typha biomass can be used to create biofuel (Cicek et al 2006;Gami et al 2011), as a soil amendment (Manios et al 2003), used to make artisanal products (Hall et al 2008), and with repeated harvests could reduce nutrient loads to adjoining aquatic systems (Boyd et al 2015), which are additional benefits of this management strategy.…”

Invasive wetland plants are the primary targets of wetland management to promote native communities and wildlife habitat, but little is known about how commonly implemented restoration techniques influence nutrient cycling. We tested how experimental mowing, herbicide application, and biomass harvest (i.e., removal of aboveground biomass) treatments of Typha-invaded mesocosms altered porewater nutrient (NO 3 -, NH 4 ? , PO 4 -3 ) concentration and supply rate, vegetation response, and light penetration to the soil surface. We found that while herbicide application eliminated the target species, it also reduced native plant density and biomass, as well as increased porewater nutrient concentration (PO 4 -3 , NO 3 -) and supply rates (N, P, K) up to a year after treatments were implemented. Because herbicide application promotes nutrient enrichment, it may increase the likelihood of reinvasion by problematic wetland invaders, as well as cause eutrophication and deleterious algal blooms in adjacent aquatic systems. Our data suggest that biomass harvest should be considered by managers aiming to reduce Typha abundance without eradicating native diversity, avoid nutrient leaching, as well as possibly utilizing biomass for bioenergy.

“…Unlike most coastal and shelf sediments, wetlands and marshes have been well documented as the effective sink of nutrients from the overlying water due to the presence of halophyte (Lin Yingfeng et al, 2002;Michael, 2003;DeBusk et al, 2004;Cicek et al, 2006;Maine et al, 2006). In Dongtan, sediments at HM and MM are covered with halophyte, dominated by Scripus mariquter and Carex scabritolis with height of 20-30 cm.…”

In an annual cycle from March 2005 to February 2006, benthic nutrient fluxes were measured monthly in the Dongtan intertidal flat within the Changjiang (Yangtze River) Estuary. Except for NH 4 + , there always showed high fluxes from overlying water into sediment for other four nutrients. Sediments in the high and middle marshes, covered with halophyte and consisting of macrofauna, demonstrated more capabilities of assimilating nutrients from overlying water than the low marsh. Sampling seasons and nutrient concentrations in the overlying water could both exert significant effects on these fluxes. Additionally, according to the model provided by previous study, denitrification rates, that utilizing NO 3 -transported from overlying water (D W ) in Dongtan sediments, were estimated to be from -16 to 193 mol·h -1 ·m -2 with an average value of 63 mol·h -1 ·m -2 (n=18). These estimated values are still underestimates of the in-situ rates owing to the lack of consideration of D N , i.e., denitrification supported by the local NO 3 -production via nitrification.

“…biotic regulation and aesthetic values) in both the wetland and the surrounding landscape (Siracusa and La Rosa 2006). Nutrients accumulating in plants may also be used for composting or energy generation as additional benefits (Cicek et al 2006). Harvested plants can be used for biogas production through fermentation, a practice widely used in developing countries and Europe.…”
