Beaver pond biogeochemical effects in the Maryland Coastal Plain

  title={Beaver pond biogeochemical effects in the Maryland Coastal Plain},
  author={David L. Correll and Thomas E. Jordan and Donald E. Weller},
The fluxes and concentrations ofmaterials from two contiguous second-order watershedsin the Coastal Plain of Maryland, U.S.A. were measuredfor six years prior to and six years subsequent to theformation of a 1.25 ha beaver pond near the bottom ofone of the watersheds. The watersheds have a clayaquiclude and were equipped with V-notch weirs andcontinuous volume-integrating water samplers. Thebeaver pond reduced annual discharge of water,total-N, total-P, dissolved silicate, TOC, and TSS by8, 18…

The Effect of Beaver Ponds on Water Quality in Rural Coastal Plain Streams
Abstract We compared water-quality effects of 13 beaver ponds on adjacent free-flowing control reaches in the Coastal Plain of rural North Carolina. We measured concentrations of nitrate, ammonium,
N budgets and aquatic uptake in the Ipswich River basin, northeastern Massachusetts
[1] We calculated N budgets and conducted nutrient uptake experiments to evaluate the fate of N in the aquatic environment of the Ipswich River basin, northeastern Massachusetts. A mass balance
Sediment and nutrient storage in a beaver engineered wetland
Results indicate that beaver ponds may help to mitigate the negative off‐site impacts of accelerated soil erosion and diffuse pollution from agriculturally dominated landscapes such as the intensively managed grassland in this study.
Beaver dams along an agricultural stream in southern Ontario, Canada: their impact on riparian zone hydrology and nitrogen chemistry
The hydrology and nitrogen biogeochemistry of a riparian zone were compared before and after the construction of beaver dams along an agricultural stream in southern Ontario, Canada. The beaver dams
Reduction of High Nitrate Concentrations in a Central New York State Stream Impounded by Beaver
Abstract The influence of Castor canadensis (North American Beaver) impoundments on the loss of nitrate (NO3-) from stream water was monitored for 14 months at four sites in Homer Gulf Creek in
The Biogeochemistry of Boreal Beaver Ponds
The flooding of soils by beaver dams causes the depletion of oxygen and development of anaerobic conditions that alter biogeochemical processes. Field studies showed that, as anaerobic conditions
Impact of Beaver Pond Colonization History on Methylmercury Concentrations in Surface Water.
The results show that pioneer inundation by beavers can increase MeHG concentrations in streams, but that this effect is negligible when dams are reconstructed on previously used ponds, and it is expected that the recovery and expansion of beavers in the boreal system will only have a transitional effect on MeHg in the environment.
The Geomorphic and Hydrologic Impact of Beaver Dams on Headwater Streams in Northeastern Connecticut and Implications for River Restoration
Of the many types of barriers to water flow, beaver dams are among the smallest, typically lasting less than a decade and rarely exceeding 1.5 meters in height. They are also among the most frequent
Spatiotemporal dynamics of boreal landscapes with ecosystem engineers: beavers influence the biogeochemistry of small lakes
It has been suggested that beavers affect biogeochemical processes and the environment on a relatively large scale, thus acting as ecosystem engineers. In this long-term study we evaluated the
Basins, beaver ponds, and the storage and redistribution of trace elements in an industrially impacted coastal plain stream on the Savannah River Site, SC, USA.
Assessment of contaminants in stream systems should include such slow-water, extreme depositional zones such as beaver impacted areas or basins to verify what contaminants may be pulsing through the stream.


The effect of beaver ponds on the nonpoint source water quality of a stream in Southwestern Wyoming
Currant Creek, a second order stream in southwestern Wyoming, has three large complexes of beaver ponds midway along its 32 km length. To determine whether these ponds improve the quality of water
Nutrient mass balances for the watershed, headwaters intertidal zone, and basin of the Rhode River Estuary'
Mass balances were determined for a 13-month period for three parts of the Rhode River ecosystem, a small subestuary of the Chesapeake Bay. Organic matter, nitrogen, and phosphorus budgets were

Temporal and longitudinal variations in the chemistry of two tributary streams of Woods Lake in the Adirondack Mountains of New York were monitored before and after a watershed CaCO3 application. One

Abstract Natural variations in concentrations of 18 O, D, and H 4 SiO 4 in two tributary catchments of Woods Lake in the west-central Adirondack Mountains of New York were measured during 1989–1991

Phosphorus and nitrogen mass balances of five wetlands (two beaver ponds, two conifer-Sphagnum swamps and one sedge fen) situated in three catchments in central Ontario, Canada, were measured.
