“…For example, North American prairie potholes and parkland wetlands may face both quantitative and qualitative deterioration of habitat owing to more drought years in coming decades (e.g. Larson 1995). This could force some ducks to switch to alternative breeding grounds further north in the boreal forest, which is expected to result in a general decrease in the size of North American duck populations (Sorenson et al 1998, Forcey et al 2011, Withey & van Kooten 2011.…”

The policy of the European Commission prohibits hunting of migratory birds while they travel to their breeding grounds. To date, spring migration dates of ducks have mainly been determined using bird counts, but the validity of this sometimes disputed method has never been tested. We used ring-recovery data from close to 9,000 teal Anas crecca ringed in the Camargue, southern France, to determine the onset of spring migration. This method makes it possible to avoid potential biases linked to duck counts, and was used to test the validity of spring migration dates inferred from such counts. Depending on the type of analysis (intra-or inter-annual recoveries), teal appeared to start migrating from the Camargue during the first or second 10-day period of January, with no significant differences between years, and no effect of the bird's age or sex. However, when taking potential winter dispersion into account, we suggest that a conservative estimate for the onset of spring migration is the first 10-day period of February. Migration dates inferred from ring-recovery analyses were consistent with earlier results from duck counts, and provide a firm basis for policy making related to hunting. Though ringing data should be preferred when available, our study suggests that determining migration dates from bird counts may be a reliable method for teal, and potentially for other dabbling and diving ducks as well.

“…A post-hoc stratification of the survey data into U.S. grassland, Canadian grassland, and Canadian parkland regions was performed and each region was modeled independently. The models for Canadian grassland and parkland regions were created using data from 1968 to 1990 and the U.S. grassland model was created using data from 1973 to 1987 (Larson, 1995). Historical climate datasets that included monthly maximum, minimum, and average temperatures and total precipitation were also obtained (Larson, 1995).…”

The wetlands also support an abundance of other species and provide ecological services valued by society. The hydrology of prairie pothole wetlands is dependent on atmospheric interactions. Therefore, changes to the region's climate can have profound effects on wetland hydrology. The relevant literature related to climate change and upland management effects on prairie pothole wetland water levels and hydroperiods was reviewed. Climate change is widely expected to affect water levels and hydroperiods of prairie pothole wetlands, as well as the biota and ecological services that the wetlands support. In general, hydrologic model projections that incorporate future climate change scenarios forecast lower water levels in prairie pothole wetlands and longer periods spent in a dry condition, despite potential increases in precipitation. However, the extreme natural variability in climate and hydrology of prairie pothole wetlands necessitates caution when interpreting model results. Recent changes in weather patterns throughout much of the Prairie Pothole Region have been in increased precipitation that results in increased water inputs to wetlands above losses associated with warmer temperatures. However, observed precipitation increases are within the range of natural climate variability and therefore, may not persist. Identifying management techniques with the potential to affect water inputs to prairie pothole wetlands would provide increased options for managers when dealing with the uncertainties associated with a changing climate. Several grassland management techniques (for example, grazing and burning) have the potential to affect water levels and hydroperiods of prairie pothole by affecting infiltration, evapotranspiration, and snow deposition.

Hydrological processes of the wetland complex in the Prairie Pothole Region (PPR) are difficult to model, partly due to a lack of wetland morphology data. We used Light Detection And Ranging (LiDAR) data sets to derive wetland features; we then modelled rainfall, snowfall, snowmelt, runoff, evaporation, the "fill-and-spill" mechanism, shallow groundwater loss, and the effect of wet and dry conditions. For large wetlands with a volume greater than thousands of cubic metres (e.g. about 3000 m 3 ), the modelled water volume agreed fairly well with observations; however, it did not succeed for small wetlands (e.g. volume less than 450 m 3 ). Despite the failure for small wetlands, the modelled water area of the wetland complex coincided well with interpretation of aerial photographs, showing a linear regression with R 2 of around 0.80 and a mean average error of around 0.55 km 2 . The next step is to improve the water budget modelling for small wetlands. Résumé Les processus hydrologiques du complexe de zones humides de la région des fondrières des prairies sont difficiles à modéliser, en partie à cause d'un manque de données de morphologie des zones humides. Nous avons utilisé des jeux de données LiDAR (Light Detection And Ranging) pour calculer les caractéristiques des zones humides. Nous avons ensuite modélisé les pluies, les précipitations neigeuses, la fonte des neiges, le ruissellement, l'évaporation, le mécanisme de débordement par saturation, les pertes des eaux souterraines peu profondes, et l'effet des conditions humides et sèches. Pour les zones humides étendues ayant un volume supérieur à quelques milliers de mètres cubes (par exemple, environ 3000 m 3 ), le volume d'eau modélisé s'accorde assez bien avec les observations, mais le modèle a été tenu en échec pour les zones humides de petite taille (par exemple, volume inférieur à 450 m 3 ). Malgré l'échec pour les petites zones humides, la zone d'eau modélisée du complexe de zones humides coïncidait bien avec l'interprétation des photographies aériennes, montrant une régression linéaire avec un R 2 de l'ordre de 0,80 et une erreur moyenne autour de 0,55 km 2 . La prochaine étape est d'améliorer la modélisation du bilan hydrique pour les zones humides de petite taille.
