“…Indeed, in China (He et al 2017) and the United States (Silliman et al 2005), severe drought has weakened marsh plants (e.g., Spartina alterniflora and Suaeda salsa), increased top-down control by common grazers, and led to runaway die-offs of marsh ecosystems due to the interaction of drought and overgrazing (Silliman & Bertness 2002, Silliman et al 2005. While fire has been used as a salt marsh management tool to prevent woody plant invasion and manage cattle impacts (Williams-Jara et al 2022), the increasing intensity and frequency of wildfires and bushfires are of growing concern because of the fires' physical impacts on plant condition (Glasby et al 2023), soil structure (Smith 2001), and invertebrate communities (Ross et al 2019).…”

Marine foundation species are the biotic basis for many of the world's coastal ecosystems, providing structural habitat, food, and protection for myriad plants and animals as well as many ecosystem services. However, climate change poses a significant threat to foundation species and the ecosystems they support. We review the impacts of climate change on common marine foundation species, including corals, kelps, corals, seagrasses, salt marsh plants, mangroves, and bivalves. It is evident that marine foundation species have already been severely impacted by several climate change drivers, often through interactive effects with other human stressors, such as pollution, overfishing, and coastal development. Despite considerable variation in geographical, environmental, and ecological contexts, direct and indirect effects of gradual warming and subsequent heatwaves have emerged as the most pervasive drivers of observed impact and potent threat across all marine foundation species, but effects from sea level rise, ocean acidification, and increased storminess are expected to increase. Documented impacts include changes in the genetic structures, physiology, abundance, and distribution of the foundation species themselves and changes to their interactions with other species, with flow-on effects to associated communities, biodiversity, and ecosystem functioning. We discuss strategies to support marine foundation species into the Anthropocene, in order to increase their resilience and ensure the persistence of the ecosystem services they provide. Expected final online publication date for the Annual Review of Marine Science, Volume 16 is January 2024. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

“…Fire directly impacts the capacity of soils to support life through altered physiochemical properties, potentially reducing the suitability of fire-effected areas for certain species. Such changes may facilitate the settlement of new or opportunistic species to an area with further implications for local ecology (Williams-Jara et al 2022). Where fertility and water retention capacity of soils have decreased following fires, repeated events preferentially facilitate the growth and proliferation of fire-tolerant soil microbial species, altering the organic component and nutrient cycles of soils (Muñoz-Rojas et al 2016;Lombao et al 2020;Sulaeman et al 2021).…”

Geodiversity elements contribute significantly to local and global hydrological, biogeochemical and ecosystem services and as such, fire is a potentially disruptive force with long-term implications. from limiting karstic speleothems formation, to compounding impacts of peat-fire-erosion cycles. Geodiversity elements additionally possess important cultural, aesthetic, and environmental values, including the support of ecosystem services. Hence, assessments of potential fire damage should consider implications for land users, society, and culture, alongside the geomorphic impacts on geodiversity elements. With a view to providing a concise set of descriptors of the response of geodiversity elements to fire, we qualify and in places, quantify, how fire may degrade geosystem function. Where possible, we highlight the influence of fire intensity and frequency gradients, and cumulative fire, in the deterioration of geodiversity values. Geoconservation is integral to protected areas with implications from fire effected geodiversity functions and values presenting issues for management, with potential consequences extending through to delisting, degazetting, and resizing of protected areas. Future research in reserve systems should concentrate on understanding the synergistic and compounding effects of fire on the geophysical landscape.

“…Prescribed fire was reported as a management tool by survey respondents from 13 of 14 states in the Flyway (Figure S8) and is commonly used to reset ecological succession; control woody species, invasive species, or dense perennials; and promote herbaceous annuals that produce food for waterfowl (Lynch 1941). While prescribed fire in other ecosystems has been extensively studied, the science of prescribed fire in freshwater emergent wetlands is relatively limited, including within the Flyway (Kirby et al 1988, Brennan et al 2005, Mitchell et al 2006, Williams-Jara et al 2022). Accordingly, empirical information on how prescribed fire may alter habitat conditions for SMBs in the Flyway is correspondingly rare.…”

Wetland management practices and secretive marsh bird habitat in the Mississippi Flyway: a review

et al. 2023

View full text Add to dashboard Cite

Management regimes on publicly owned freshwater wetlands in the Mississippi Flyway of North America (i.e., Flyway) have historically emphasized waterfowl, but there is limited information on how waterfowl‐focused wetland management affects other wetland‐dependent wildlife. Secretive marsh birds (SMBs) depend on wetlands with emergent vegetation throughout their migratory life cycle and often encounter vegetation and water conditions resulting from waterfowl‐focused management regimes. Thus, there is a need for better understanding of how SMBs are affected by wetland management and the extent to which waterfowl‐focused management regimes provide habitat for SMBs. In this review, we identify the vegetation and water conditions resulting from typical management objectives on freshwater emergent wetlands in the Flyway, review and qualitatively synthesize results from studies that directly evaluate how wetland management practices affect SMBs or their habitat, and assess how the vegetation and water conditions being produced for target species (mainly waterfowl) align with SMB habitat requirements. We searched online databases and used Google Scholar to locate peer‐reviewed literature, technical reports, and graduate theses that pertained to responses of SMBs or their habitat to water‐level manipulation, herbicide application, prescribed fire, disking, mowing, and planting crops. There are several management strategies that complement SMBs and waterfowl, such as reducing cover of woody species and providing flooded emergent vegetation. We also highlight management strategies that may not currently align with SMB life‐cycle needs and suggest adjustments that might promote habitat for SMBs while still achieving waterfowl population objectives. For example, adjusting the dates and duration of spring water‐level drawdowns on a portion of wetlands within a larger complex can provide for spring migrating waterfowl and ensure habitat for migrating and nesting SMBs. Ideally, future studies would address how modifications to management practices affect SMBs and monitor potential effects on waterfowl, resulting in a more holistic approach to wetland management.
