  1. Hager Lake Project Proposed Citizen Science Project Pend Oreille Chapter Idaho Master Naturalist Program

  2. Hager Lake Project • A Rare Biological Gem • Preserved for Posterity • A Scientific Legacy • The Proposed Work Plan

  3. Hager Lake – A Rare Biological Gem • Hager Lake is a 5-acre pond formed in a depression left with the retreat of the glaciers • Hager Lake is a valley peatland of high biodiversity • A peatland is wetland with waterlogged substrates and 12-inch accumulation of peat • Lack of oxygen and cool temperatures limit decomposition • Hager Lake contains 10 different rare plant species

  4. Rare Plants of Hager Lake • Floating mat zone – small cranberry (Vacciniumoxycoccos), rannoch-rush (Scheuchzeriapalustris) • Fixed mat zone – inundated clubmoss (Lycopodiellainundata), large St. Johnswort (Hypericummajus) • Lake margins – swaying bulrush (Schoenoplectussubterminalis) • Other areas – arctic starflower (Trientaliseuropaeassp.arctica) • Rare plants believed extripated – marsh willowherb (Epilobiumpalustre), crested woodfern (Dryopteriscristata), bristly-stalked sedge (Carexleptalea), tree groundpine (Lycopodiumdendroideum)

  7. Preserved for Posterity • Archie and Mary George were looking for land in the country with positive natural characteristics • The Nature Conservancy helped them locate the Hager Lake property • Established conservation easement on the property to protect it from development • Initially with The Nature Conservancy • Transferred to Inland Northwest Land Trust • Easement is permanent and stays with the land through sales and inheritance

  8. A Scientific Legacy at Hager Lake • Probably the best studied peatland in north Idaho • Site of pollen studies for post-glacial paleo-ecology • John Rumely completed his doctoral research on the plant ecology of Hager Lake • Field work completed 1952; thesis submitted 1956 • Bursik and Moseley conducted joint USFS and IDFG project in 1992 to revisit the work by Rumely • Focused on changes over the 40–year period • Now at 60-year point, time to revisit plant ecology again • Archie George eager for the study to be completed • No funding available for scientific crew to complete task • Can only be accomplished as volunteer project • Perfect citizen science project—significant, relevant, doable • Lynn Kinter (Idaho Natural Heritage Program) will provide technical advice

  9. Proposed Work Plan • Conduct survey of plant species present • Several trips throughout the growing season • Concentrate on finding rare species • May complete collection of voucher specimens • UI Stillinger Herbarium may help with identification • Complete transect across length of Hager property • Use the methods used by Rumely • May take 2 weeks; can stay in IDFG cabin • Look at water chemistry, lake depth, temperature • Plenty of non-technical jobs—data entry, report writing, photography, publicity
