| Abstract | —Invasive Reed Canarygrass (Phalaris arundinacea) is widespread in the Pacific Northwest, USA and develops dense, tall stands in shallow wetland habitats. Oregon Spotted Frogs (Rana pretiosa) are a species of conservation concern, and lay eggs in clusters in seasonally flooded margins of emergent wetlands. We hypothesized that reducing Reed Canarygrass might favor Oregon Spotted Frog oviposition in invaded shallows. In a Reed Canarygrass-dominated marsh, we examined probability of oviposition and thermal attributes in 32 pairs of mowed and unmowed plots. Oregon Spotted Frogs laid one cluster of egg masses in each of two mowed plots but no egg masses in unmowed plots, an unlikely result based on a binomial function (P = 0.006). We also recorded three separate Oregon Spotted Frog egg mass clusters outside of study plots, but exclusively in habitat that appeared structurally similar to mowed plots. We conclude that mowing may enhance oviposition habitat for Oregon Spotted Frogs in Reed Canarygrass-dominated wetlands. However, to have confidence in the response given our limited data, this manipulation should be repeated before this management strategy is broadly applied. Future manipulations of this system should consider how such treatments influence other Oregon Spotted Frog life stages and co-occurring species. |
