Invasive Phragmites australis management outcomes and native plant recovery are context dependent

Abstract The outcomes of invasive plant removal efforts are influenced by management decisions, but also contingent on the uncontrolled spatial and temporal context areas. Phragmites australis is an aggressive invader that intensively managed in wetlands across North America. Treatment options have been understudied, ecological contingencies poorly understood. We implemented a 5‐year, multi‐site experiment to evaluate six treatments varied timing (summer or fall) types herbicide (glyphosate imazapyr) along with mowing, plus nonherbicide solarization treatment. evaluated for their influence native cover inflorescence production. assessed community trajectories environmental factors. summer mow, fall glyphosate spray treatment resulted low cover, high reduction, provided best conditions recruitment. However, returning communities did not resemble reference sites, which were dominated ecologically important perennial graminoids. Native recovery following initial was likely limited dense litter from mowing. After 5 years, mortality highly variable sites as driven hydrology. Plots higher soil moisture had greater reduction more robust recruitment natives compared plots. This effect may limit semiarid regions vulnerable water scarcity. demonstrate importance replicating species experiments so successes failures can be better

Abiotic and Landscape Factors Constrain Restoration Outcomes Across Spatial Scales of a Widespread Invasive Plant

Frontiers in Plant Science, Год журнала: 2019, Номер 10

The natural recolonization of native plant communities following invasive species management is notoriously challenging to predict, since outcomes can be contingent on a variety factors including decisions, abiotic factors, and landscape setting. spatial scale at which the treatment applied also impact outcomes, potentially influencing assembly processes success. Understanding relative importance each these for community help managers prioritize patches where specific treatments are likely most successful. Here, using effects size analyses, we evaluate responses four Phragmites australis (1: fall glyphosate herbicide spray, 2: summer 3: imazapyr 4: untreated control) two patch scales (12,000 m2 1,000 m2) monitored five years. Using variation partitioning, then evaluated independent shared influence scale, type, treatments. We found that reinvaded more quickly in large patches, particularly treatments, while cover richness recolonized greater magnitude small than large. Patch combination with was important driver responses. Compared plots, commonly had deeper prolonged flooding, were areas hydrologic disturbance landscape, associated reduced recruitment cover. Small less flooding disturbance, plants surrounding promoted higher conservation values, richness. Herbicide type timing accounted very little recovery, emphasizing selection better outcomes. To maximize success programs, practitioners should first manage adjacent species, minimal disturbance.

Effective suppression of established invasive Phragmites australis leads to secondary invasion in a coastal marsh

Invasive Plant Science and Management, Год журнала: 2021, Номер 14(1), С. 9 - 19

Abstract Invasive species negatively impact vegetation communities. European common reed [ Phragmites australis (Cav.) Trin. ex Steud. ssp. ] is rapidly spreading throughout North American wetlands. As such, the suppression of P. populations a goal many managers, as its removal should provide an opportunity to restore native In Ontario, managers applied glyphosate-based herbicide more than 400 ha in ecologically significant coastal marshes, representing first time this tool was used over standing water suppress invasive Canada. Using before–after–control–impact monitoring design, we evaluated efficacy at removing along water-depth gradient and assessed recovery community for 2 yr after treatment relation reference conditions. We found that suppressed 99% 1 worked effectively entire (10 48 cm). However, post-treatment remains distinctive from marsh treatment. plots where removed, nonnative frog-bit ( Hydrocharis morsus-ranae L.) now dominant, likely aided by high lake-water levels.

Invasive Aquatic Vegetation in the Sacramento–San Joaquin Delta and Suisun Marsh: The History and Science of Control Efforts and Recommendations for the Path Forward

San Francisco Estuary and Watershed Science, Год журнала: 2023, Номер 20(4)

Опубликована: Фев. 3, 2023

Invasive aquatic vegetation (IAV) is a management challenge in the Sacramento–San Joaquin Delta and Suisun Marsh that has commanded major resource investment for 4 decades. We review history supporting science of chemical, biological, mechanical control IAV March, flowing waters outside region. Outside Delta, there significant research on lotic systems, but few studies come from tidal environments, we found no investigations at spatial scale like Delta. The efforts nascent seen marked growth over recent decade. Since 1983, invasive submerged floating species been centralized within California State Parks Division Boating Waterways (CDBW). program relies herbicides, with an annual budget exceeded $12.5 million since 2015. However, results have mixed because applying herbicides effectively system. In parallel, biological agents water hyacinth (Eichhornia crassipes) giant reed (Arundo donax) released not provided appreciable benefit, likely they are suited temperate climate. Over decades, regulatory complexity increased, hampering to innovate alternative methods or respond quickly new invaders. Control common (Phragmites australis), main emergent plants, coordinated under central program, investigate strategies only recently permitted. As result, local published outcomes these species. Based this our science, develop recommendations leadership actions proactively manage IAV.

Common approaches to introduced species management face widespread acceptance problems in the United States

Abstract Decisions on whether and how to manage introduced species can be controversial, but public attitudes towards management (ISM) are poorly understood. Despite the potential disruptive impacts of such controversies relations conservation goals, decision‐makers currently left with little information social acceptability different alternatives. To better understand core features ISM in United States, we conducted an online experiment vignettes describing hypothetical realistic scenarios, varying targeted taxon (insect or plant), control method (mechanical, chemical biological), risk severity (low high) type non‐target (to humans native species). Not surprisingly, low was most acceptable, particularly for mechanical control. In high‐risk only by a slim majority respondents. Overall, biological controls showed levels acceptability. Surprisingly, there no significant difference respondents ranked risks people species. Beyond differences between factors, also find that were associated respondents' demographic characteristics. Policy Implications . our findings indicate widespread should not assumed. While activities representing low‐risk scenarios some support public, results highlight disconnect effectiveness common methods their Our need evidence‐guided ISM, which includes evidence harmful species, as well benefits activities, one way increase non‐native management.

Significant Increase in Nutrient Stocks Following Phragmites australis Invasion of Freshwater Meadow Marsh but Not of Cattail Marsh

Frontiers in Environmental Science, Год журнала: 2019, Номер 7

Опубликована: Июль 11, 2019

Invasive species are a threat to biodiversity and can cause ecological degradation, however, well-established invasive may serve valuable functions. For example, in the Laurentian Great Lakes, where nutrient pollution is major issue, highly productive Phragmites australis (European Common Reed) provide retention service. Yet there lack of research comparing carbon macronutrient stocks P. with resident plant communities, such as cattail meadow marsh. We quantified effect invasion on standing freshwater coastal marsh by above- belowground biomass, tissue concentrations, annual invaded (dominated Typha spp.) Calamagrostis canadensis), which being displaced Lake Erie conclude that dependent community replaced. The stock carbon, nitrogen, phosphorus, potassium consistent between australis-invaded marsh, though contains more magnesium (112 % mean increase) calcium (364 increase). In contrast, when replaces all measured nutrients increase significantly (103 - 188 Our study highlights invasions create trade-offs ecosystem services. our case, invades should be weighed against documented reductions habitat value.
