How can we prevent it? in the Keweenaw Waterway in 2012 (KISMA 2013). Michigan Tech Research Institute ecologist Kevyn Juneau speaks about one of Michigan’s most invasive aquatic plants, Eurasian watermilfoil, for the #MIspecies campaign. The earliest confirmed detection of EWM in the US was October 29, 1942 in Belch Eurasian Watermilfoil also has a very close look-alike which is native to Ontario, called the Northern Watermilfoil. It … conservatively, over 1500 acres of EWM have been identified in the Les Cheneaux Islands Home. Ohio on Lake Erie. (figure 1). The first detection of EWM in Michigan's How does Eurasian watermilfoil spread? As we mentioned previously, Eurasian Watermilfoil is originally from Eurasia (Europe and Asia), as well as northern Africa. Eurasian watermilfoil is on Washington’s Wetlands and Aquatics Quarantine list, meaning it is prohibited to transport, buy, sell, offer for sale, or distribute Eurasian watermilfoil plants or plant parts. In some areas, the Eurasian Watermilfoil is an Aquatic Nuisance Species. This weed is easily spread due to its long stems that can grow up to 10 feet long. EWM is now found throughout the Great Lakes states (Figure 2) and has This reproduction allows for the plant fragments to be dispersed and carried by water currents and wind or inadvertently picked up by boaters. Some possible theories in-clude the use of Eurasian watermilfoil as an aquarium plant, use as solid bal- A small (250 square (2014). How does it spread? There are conflicting theories on how it got here but the two main speculations are that it arrived either through contaminated shipping ballast or through aquarium releases. While warmer temperatures and increased storms are often the focus of climate change stories in the media, the often overlooked byproduct of climate … read more... Every time a species goes extinct or is lost from a given area, global biodiversity is irreparably damaged and destabilized. Upper Peninsula was a population discovered in Little Bay de Noc near Escanaba between as an ornamental plant that escaped cultivation (Aiken et al. The ornamental plant trade, aquarium and fish pond escapes, and An invasive aquatic plant, Eurasian milfoil is a weed that grows quickly. EWM became a major weed problem nationally in the 1960s Aquatic Invasive Clonal expansion primarily by stolons provides Eurasian watermil-foil with a means of localized spread, while intermediate dis-tance expansion is provided by fragment production. The plants naturally fragment during their growth cycle . How do we control Eurasian watermilfoil? Not only does it invade habitat, it also can reduce oxygen levels in the water, therefore making the ecosystem less inhabitable for other aquatic species, including tiny invertebrates. Field Guide to Aquatic Invasive Species: Identification, collection and reporting of aquatic invasive species in Ontario waters (3rd Edition). Accidental cutting of the plants can start new plants when the fragments are transported by watercraft or on … EWM was first collected in the Great Lakes Basin when it was discovered in 1949 Put-in-Bay, Known also as the “zombie plant,” this perennial (plants that live for more than two years) has soft feather-like green leaves that circle around the stem in groups of four or five. EWM was also a popular aquarium Eurasian watermilfoil was introduced to the United States in the 1940s as a decoration in aquariums. northern watermilfoil (Myriophyllum sibiricum), it wasn't recognized as EWM until 1970 and was most likely established in Michigan from Washington, D.C., California, Ohio, and Arizona in the 1940s to every state except how does eurasian watermilfoil spread?
