Using salt marshes for coastal protection: effective but hard to get where needed most

Beatriz Marin-Diaz talks about her and research colleagues’ latest article, where they monitored wave run-up on Dutch dikes over the course of 3 years. Through comparing different dike locations, some fronted by salt marshes and others fronted by bare tidal flats without vegetation, results could be linked to the long-term marsh development in the area. Introduction Salt marshes are wetlands in coastal areas that provide … Continue reading Using salt marshes for coastal protection: effective but hard to get where needed most

Eight steps to urban amphibian conservation: Framework to translate ecological knowledge to action

New research by Lee et al. demonstrates the utility of an eight-step framework to identify priority wetland habitats and movement corridors for urban amphibian conservation in cities. Author Nicole Kahal explains more in this blog post. Amphibians are one of the most imperilled species assemblages with diversity and abundance declines reported globally. Considered a key indicator of ecological condition, amphibians face many challenges in the … Continue reading Eight steps to urban amphibian conservation: Framework to translate ecological knowledge to action

The importance of wetland margin microhabitat mosaics

The use of microhabitats for thermoregulation in wetland species is poorly studied. In their latest research, Ryeland and colleagues conduct field observations of nine species of shorebird to test whether birds selectively use microhabitats across temperatures. Wetlands, and the species that rely upon them, are under significant threat world‐wide, and managing habitat for migratory wetland species, such as shorebirds, is particularly challenging because it requires … Continue reading The importance of wetland margin microhabitat mosaics

Urban wetland conservation may unintentionally benefit mosquitoes

As urban wetlands become more prevalent, Jayne Hanford and colleagues look into how other species, not just those of conservation focus, might benefit from our management efforts. What happens when those additional species could be problematic for nearby human populations? Wetlands are one of the world’s most valuable but also most threatened ecosystems. The services they provide include biodiversity conservation, flood mitigation, water purification, and … Continue reading Urban wetland conservation may unintentionally benefit mosquitoes

Wet wetlands restore better

With Plant Conservation Day in mind, Samantha Dawson’s post discusses characteristics of wetland plants and her new paper, Plant traits of propagule banks and standing vegetation reveal flooding alleviates impacts of agriculture on wetland restoration. Many of the world’s wetlands are highly degraded and they are one of the most threatened types of ecosystems. To attempt to halt or reverse this trend, there are lots of … Continue reading Wet wetlands restore better

More accurate mapping of coastal wetlands is vital for their management and conservation

In this post, Associate Editor Nathalie Butt discusses a recent paper ‘Habitat mapping of coastal wetlands using expert knowledge and Earth Observation data’ by Maria Adamo, Cristina Tarantino, Valeria Tomaselli, Guiseppe Veronico, Harini Nagendra and Palma Blonda. Habitats at risk What do we usually think of when we hear ‘wetland’ or ‘coastal wetland’? A flat marshy area by the sea somewhere, perhaps with a bird … Continue reading More accurate mapping of coastal wetlands is vital for their management and conservation

Environmental DNA and crayfish management

In this post Matthew Dougherty discusses his recent paper ‘Environmental DNA (eDNA) detects the invasive rusty crayfish Orconectes rusticus at low abundances‘ Tangled buoy strings, lost traps, pinched fingers, sweaty brows, and boats smeared with beef liver: these images define the experiences of countless managers and scientists who use baited trapping to monitor crayfish invasions, especially in lakes of the upper Midwest, USA. While these … Continue reading Environmental DNA and crayfish management

Conservation of wet grassland birds

In this post Michał Żmihorski discusses his paper ‘Effects of water level and grassland management on alpha and beta diversity of birds in restored wetlands’ A lot of species associated with wetlands are rare and declining and therefore large economical resources are being put into the conservation of wetlands given that they are hotspots for wetland birds and wet grassland birds. However, few studies have … Continue reading Conservation of wet grassland birds

Lessons in how to restore a wetland ecosystem

In this post David Moreno Mateos discusses his paper ‘Ecosystem response to interventions: lessons from restored and created wetland ecosystems’ After over 30 years and billions of dollars (and euros, pounds, and yuans) of restoring wetlands globally, and especially in the USA, the time has come to evaluate the results, and particularly to find out how wetlands are responding to our efforts. The results found … Continue reading Lessons in how to restore a wetland ecosystem

Managing native fish with environmental flows

Flow alteration is one of the most common threats to rivers and streams around the world. Alterations such as weirs, dams and water withdrawal for human uses tend to suppress natural flow variation causing a disconnection between rivers and floodplain wetlands. These changes to the natural hydrology of rivers can have detrimental effects for fish communities because many species of fish rely on periodic access to … Continue reading Managing native fish with environmental flows
