Leopold's Arboretum Needs Upstream Water Treatment to Restore Wetlands Downstream

Joy Zedler, James Doherty, Isabel Rojas
2014 Water  
A case study has broad relevance for urban natural reserves.  ...  Regulations for total maximum daily loads (TMDLs) have led local municipalities to expand pre-existing sediment-and nutrient-trapping ponds from 5.67 ha (14 ac) of Arboretum land to 9.3 ha (23 ac) to protect  ...  Will more N and P be released during dredging than will be trapped after dredging? Will a deeper Curtis Pond remove less N?  ...
