“…According to the National Wetland Plants List of the US, species of Typha are considered obligate wetland plants, meaning they cannot survive in non-wetland habitats (Lichvar et al 2016). As such, Typha is found in a wide variety of wetland habitats including marshes, shores, streambanks, ditches, and margins of lakes and ponds, and tidal wetlands showing a tolerance for a range of water levels (Harris and Marshall 1963;Stewart and Kantrud 1972;Newman et al 1998;Safratowich et al 2008). Typha invasions into natural wetlands are often associated with hydrologic alterations.…”

“…The first collection of T. angustifolia was in 1942, and the first verified specimen of T. × glauca was in 1963. Since that time, Typha has become ubiquitous throughout the region (Stewart and Kantrud 1972;Kantrud 1986;Ralston et al 2007;Safratowich et al 2008;Post van der Burg et al 2014). Potholes have been associated with T. angustifolia and T. latifolia, and T. × glauca has become dominant in many areas Kantrud 1971, 1972;Kantrud 1986).…”

Typha (Cattail) Invasion in North American Wetlands: Biology, Regional Problems, Impacts, Ecosystem Services, and Management

Typha is an iconic wetland plant found worldwide. Hybridization and anthropogenic disturbances have resulted in large increases in Typha abundance in wetland ecosystems throughout North America at a cost to native floral and faunal biodiversity. As demonstrated by three regional case studies, Typha is capable of rapidly colonizing habitats and forming monodominant vegetation stands due to traits such as robust size, rapid growth rate, and rhizomatic expansion. Increased nutrient inputs into wetlands and altered hydrologic regimes are among the principal anthropogenic drivers of Typha invasion. Typha is associated with a wide range of negative ecological impacts to wetland and agricultural systems, but also is linked with a variety of ecosystem services such as bioremediation and provisioning of biomass, as well as an assortment of traditional cultural uses. Numerous physical, chemical, and hydrologic control methods are used to manage invasive Typha, but results are inconsistent and multiple methods and repeated treatments often are required. While this review focuses on invasive Typha in North America, the literature cited comes from research on Typha and other invasive species from around the world. As such, many of the underlying concepts in this review are relevant to invasive species in other wetland ecosystems worldwide.

“…The higher abundance and frequency of occurrence of Red-winged Blackbird on roadside surveys is possibly because of a greater abundance of dense marsh vegetation around the relatively deep water bodies that form in ditches and livestock watering holes (Niemuth et al 2007, Safratowich et al 2008 in which this species nests, and near cropland (Yasukawa and Searcy 1995) in which it forages. Similar to the findings of other studies in the Canadian grasslands, we found that the Vesper Sparrow was more prevalent on roadside routes (Sutter et al 2000).…”

ABSTRACT. Grassland bird species continue to decline steeply across North America. Road-based surveys such as the North American Breeding Bird Survey (BBS) are often used to estimate trends and population sizes and to build species distribution models for grassland birds, although roadside survey counts may introduce bias in estimates because of differences in habitats along roadsides and in off-road surveys. We tested for differences in land cover composition and in the avian community on 21 roadside-based survey routes and in an equal number of adjacent off-road walking routes in the grasslands of southern Alberta, Canada. Off-road routes (n = 225 point counts) had more native grassland and short shrubs and less fallow land and road area than the roadside routes (n = 225 point counts). Consequently, 17 of the 39 bird species differed between the two route types in frequency of occurrence and relative abundance, measured using an indicator species analysis. Six species, including five obligate grassland species, were more prevalent at off-road sites; they included four species listed under the Canadian federal Species At Risk Act or listed by the Committee on the Status of Endangered Wildlife in Canada: Sprague's Pipit (Anthus spragueii), Baird's Sparrow (Ammodramus bairdii), the Chestnut-collared Longspur (Calcarius ornatus), and McCown's Longspur (Rhynchophanes mccownii). The six species were as much as four times more abundant on off-road sites. Species more prevalent along roadside routes included common species and those typical of farmland and other human-modified habitats, e.g., the European Starling (Sturnus vulgaris), the Black-billed Magpie (Pica hudsonia), and the House Sparrow (Passer domesticus). Differences in avian community composition between roadside and off-road surveys suggest that the use of BBS data when generating population estimates or distribution models may overestimate certain common species and underestimate others of conservation concern. Our results highlight the need to develop appropriate corrections for bias in estimates derived from roadside sampling, and the need to design surveys that sample bird communities across a more representative cross-section of the landscape, both near and far from roads.L'échantillonnage hors route révèle une communauté d'oiseaux de prairie différente de celle issue de l'échantillonnage le long des routes : répercussions sur la conception des relevés et les estimations pour orienter la conservation RÉSUMÉ. Le déclin prononcé des espèces d'oiseaux de prairie se poursuit en Amérique du Nord. Les relevés le long des routes, comme le Relevé des oiseaux nicheurs (BBS) en Amérique du Nord, sont souvent utilisés pour estimer les tendances et la taille des populations, ainsi que pour élaborer des modèles de répartition d'espèces de prairie, même si les dénombrements le long des routes peuvent introduire des biais relatifs aux estimations étant donné que les milieux le long des routes sont différents de ceux hors route. Nous avons examiné s'il y avait des d...

Globally, habitat loss and land conversion are major drivers of bird population decline. To halt the decline, it is essential that habitat conservation and restoration efforts are based on an understanding of how individual species use their habitat. Here, we examine habitat use by Red-winged Blackbirds (Agelaius phoeniceus) by quantifying their probability of occurrence in different land cover types and in association with varying degrees of habitat modification across most of the species’ range. To do so, we used the citizen-science eBird dataset, in combination with MODIS land cover data to model site occupancy for two breeding seasons and related presence/absence to the Global Human Modification Index. We found that Red-winged Blackbirds occupy rural and suburban habitats at higher probabilities than they do habitats with high levels of urbanization, and at similar or higher probabilities than they do their historic, natural habitats. Furthermore, we found that occurrence probability peaks at intermediate values of the Global Human Modification Index. The results were consistent across most ecoregions and the geographic range of the species, confirming that the Red-winged Blackbird is a suburban-adaptable species, persisting in moderately disturbed environments. Although more research is needed to understand the ecological and evolutionary consequences of this pattern of habitat use, our results provide novel data on Red-winged Blackbird habitat use in the midst of increasing urbanization. More broadly, they provide insight into how common, widespread avian species may be affected by anthropogenic disturbance and highlight the importance of rural and suburban environments in urban ecology and evolution.
