Apostle Islands National Lakeshore Plovers and Pigweed Peggy Burkman, Biologist, National Park Service Presented by Kelly Kearns, WI DNR What's in a Name? Charadriidae (plovers) Charadrius melodus Charadrius – root word is charade Melodus - reference to their sound Female Male Piping Plover Populations Status • Globally – • threatened (Atlantic Coast and Great Plains populations, and • endangered (Great Lakes population 1986) • Wisconsin - Federally and State endangered (1979) • Long Island added to the park in 1986 • Critical habitat designated at Apostle Islands in 2001 Recovery Plan Recovery Objective - “restore and maintain a viable population (95% or greater chance of persisting 100 years) to the Great Lakes region and remove the Great Lakes population from the list of Threatened and Endangered Species by 2020”. Recovery Criteria – “the population has increased to at least 150 pairs (300 individuals), for at least 5 consecutive years, with at least 100 breeding pairs (200 individuals) in Michigan and 50 breeding pairs (100 individuals) distributed among sites in other Great Lakes states”. Long Island 1959 – birds on Long Island 1974 - regular nesting on Long Island 1978-1983 – WI nesting limited to Long Island 1984-1998 – no successful nesting 1998-2011- successful nesting in WI limited to the Apostle Islands 2012 – Chicks hatched in Door County Protecting Piping Plovers Ongoing challenge: •Loss of habitat from development •Pets, dirt bikes, ATV’s •Predation by crows, ring-billed gulls, and mammals Cooperation and Management •Cooperative efforts between NPS, USFWS, DNR, TNC, and the Bad River Tribe •Educate the public using a variety of methods •Monitor to detect birds and nests •Construct nest exclosures •Creating buffer zones ouse of signs •Enforcing laws oATV’s are not allowed oDogs must be on a leash What Is it????? Cycloloma atriplicifolium – aka winged pigweed, tumble ringwing, plains tumbleweed, and tumble-weed Surveys • Over 3,000 plants in 2011 • Many directly in piping plover critical habitat Additional Plants just found on Chequamegon Point Decision Time • Species originally from west of Mississippi River (southwestern tribes) • Considered adventive in the east • An annual but each shrub has about 27,000 seeds • Prefers dry, open, or disturbed areas • Observed in the U.P. of Michigan to take over • Directly competing with an endangered species in designated critical habitat Action Chosen • • • • Critical habitat Endangered species Efficacy of actions Hand pulling Compliance • Section 7 Consultation Funding DNR GLRI NPS Northwoods Cooperative Weed Management Area • Bad River Tribe • • • • • Action Future • Long Island • Michigan Island • Others?????
