Aquatic ecosystems can be sources of greenhouse gases. Beaver (Castor canadensis) ponds represent a unique and understudied ecological niche with the potential to influence greenhouse gas dynamics. Beavers are well known ecosystem engineers whose dam building transforms flowing streams into ponded wetlands that provide many ecosystem services, including carbon sequestration, while potentially increasing CH4 and CO2 emissions. This research aims to identify the role of beaver ponds on CH4 and CO2 fluxes through seasonal sampling with static chambers. We also measured dissolved oxygen, temperature, water depth, and nutrient concentrations. Chambers for gas collection, as well as depth sensors, were both deployed at upstream controls and pond locations at three different sites, including a suburban, agricultural, and forested site. In the suburban site, net CO2 production was higher in the pond location than in the upstream control; the suburban pond emitted CO2 at a rate of 9.98 mg C/L/m ± 14.27 while the control emitted 7.37 mg C/L/mppm±9.83. In contrast, the pond and control at the agricultural location had very similar fluxes (pond: 2.52 mg C/L/m±0.78, control: 2.42 mg C/L/m±0.5). Based on preliminary results, beaver dam ponds have the potential to emit more greenhouse gases, but patterns vary with land use, suggesting that site characteristics can mediate beaver effects.
