tabular digital data The Grass Carp Removal Program (GCR) is a component of the U.S. Fish and Wildlife Services (USFWS) Alpena Fish and Wildlife Conservation Office (FWCO) Aquatic Invasive Species (AIS) Program. The GCR Program began in 2018 as a multi-jurisdictional response strategy. Federal, state, and university partners are working collaboratively to suppress Grass Carp populations in Lake Erie and prevent their establishment elsewhere.Surveys have occurred annually from 2018- Present. Sampling focuses on rivers, wetlands, bays, and other nearshore areas of Lake Erie, Lake Michigan, and Lake Huron. Sampling focus, protocols, and priority locations are determined by the Grass Carp Advisory Committee (GCAC), a sub-committee of the Lake Erie Committee (LEC), and contributes to the shared goals of the Invasive Carp Regional Coordinating Committee (ICRCC).Standardized response sampling protocols for adult grass carp determine sampling gear, site selection, and sampling approach for each sampling event. Grass Carp are collected using a variety of sampling gears with the most utilized including: electrofishing, trammel nets, gill nets, and hoop nets. The sampling season generally occurs from April – December, however, not all locations are sampled on a similar temporal scale, particularly those locations that are not high priority. Sampling Protocols include Sustained, Exploratory, Spawning, Targeted, and Realtime Response strategies. This table contains environment, habitat, and water quality data collected during sampling events. This dataset contains fisheries data collected in the Great Lakes and tributaries that help inform critical objectives of the Lake Erie Committee and the Grass Carp Advisory Committee. -89.593506 -75.179443 46.830134 41.013066 None The United States Fish and Wildlife Service (Service) shall not be held liable for improper or incorrect use of the data described and/or contained herein.

Floating leaf plants typically grow in protected areas where there is little wave action. USFWS Submerged Submerged plants have stems and leaves that grow entirely underwater, although some may also have floating leaves. Flowers and seeds on short stems that extend above the water may also be present. Submerged plants grow from near shore to the deepest part of the littoral zone and display a wide range of plant shapes.

Data is observational, no substrate samples are taken. USFWS Clay Determined by the producer. Taking into account the whole area being sampled, the majority of the substrate consists of particles that are smaller than silt and generally less than 0.003 mm in diameter. USFWS Sand Determined by the producer. Taking into account the whole area being sampled, the majority of the substrate consists of tiny, gritty particles of rock that are smaller than gravel but coarser than silt (gritty, up to ladybug size) generally from 0.6 to 2.0 mm in diameter. USFWS Gravel Determined by the producer. Taking into account the whole area being sampled, the majority of the substrate consists of stones ranging from tiny quarter-inch pebbles to rocks of about 2 inches (fine gravel - pea size to marble size; coarse gravel - marble to tennis ball size). USFWS Rock Determined by the producer. Taking into account the whole area being sampled, the majority of the substrate consists of the rocks on the bottom are greater than 10 inches (between a basketball and a car in size) or bottom is solid rock (or rocks bigger than a car).

Taking into account the whole area being sampled, the majority of the shorline consists of structures placed along the river bank to stabilize or protect the bank from erosion. Revetments are usually constructed out of stone but other materials have been used with success including concrete-mat, willow plantings, gabions, and a host of other materials. Riprap Determined by the Producer. Taking into account the whole area being sampled, the majority of the shorline consists of a permanent layer of large, angular stone, cobbles, or boulders typically used to armor, stabilize, and protect the soil surface against erosion Seawall Determined by the Producer. Taking into account the whole area being sampled, the majority of the shorline consists of an upright structure that is steeper than 1.5 feet vertical to one foot horizontal and that is installed parallel to the bank to prevent the sliding or slumping of the land and to protect the adjacent upland from the action of surface water. Seawalls are commonly constructed of timber, rock (including gabions), concrete, steel or aluminum sheet piling, and may incorporate biological components. enviro_year Calendar year (yyyy) that sampling event took place.
