Eurasian Watermilfoil: Status And Management In Iowa, Gary S. Phillips
Eurasian Watermilfoil: Status And Management In Iowa, Gary S. Phillips
Journal of the Iowa Academy of Science: JIAS
In 1993, Eurasian watermilfoil (Myriophyllum spicatum L.) was discovered in Crystal Lake, Hancock County, Iowa. During the next three years, new infestations were discovered by the Iowa Department of Natural Resources (IDNR) fisheries personnel in four Iowa lakes. In July 1996, a program was established by the IDNR to address the threat posed by Eurasian watermilfoil to Iowa's aquatic ecosystems. As part of the Eurasian Watermilfoil Program, statewide aquatic vegetation monitoring was begun to identify those lakes currently infested with Eurasian watermilfoil. Monitoring activities were conducted by IDNR field technicians during the summers of 1996 through 2000. During this time …

Status Of Aquatic Vascular Plants 1n Iowa's Natural Lakes, G. S. Phillips
Journal of the Iowa Academy of Science: JIAS
Conversion of wetlands to agricultural land during the settlement of Iowa has resulted in a significant decline in the total area of lake habitat in the state. This reduction in area, combined with the degradation of remaining sites, resulted in dramatic reductions in aquatic vascular plant populations associated with Iowa's natural lakes. While declines in plant species inhabiting fen, bog, seepage, prairie pothole, and marsh type wetlands have been extensively documented, few quantitative data exist for lake type wetlands. During the summer of 1996, a total of 86 natural lakes in Iowa were surveyed for aquatic vascular plants. Many of …
