Northeastern Iowa Forest Monitoring

Project

Principal Investigator: Stephen J. Dinsmore


Student Investigator: Two undergraduate field technicians


Collaborators: Katy Reeder, Iowa Department of Natural Resources


Duration: 15 April 2013 to 30 June 2016


Funding Source(s): Iowa Department of Natural Resources


 


Goals and Objectives:


  • Monitor breeding birds with Multiple Species Inventory and Monitoring (MSIM) protocols to gauge responses to forest habitat management.
  • Monitor butterflies with Visual Encounter Surveys (VES) to gauge responses to forest habitat management.

Progress:


                Bird surveys were focused on sampling the breeding bird community, and we thus limited to the primary nesting season for Iowa (late May through early August). We repeated surveys in 2015, but with a total of 132 point counts in 44 stands in the period 19 May to 14 August detecting a total of 4,211 individuals of 72 species (Table 2). Species with the greatest number of detections in 2015 included American Crow (199), Northern Cardinal (164), and American Robin (159). However, surveys also detected 14 SGCN birds including Black-billed Cuckoo, Red-headed Woodpecker, Least Flycatcher, Bell’s Vireo, Wood Thrush, Blue-winged, Cerulean, and Hooded warblers, and Yellow-breasted Chat.


                Butterfly surveys were focused during the primary summer flight season for most species. We repeated butterfly surveys in 2015 when we sampled 44 stands 3 times (132 total VES) in the period 22 May through 14 August and documented 607 individuals of 30 species across all sites (Table 4). Weather was more favorable than in 2013 with respect to flight seasons on most species. Species with the greatest number of detections included Red Admiral (36), Eastern Tiger Swallowtail (30), and Great Spangled Fritillary (24). No target species were found. Surveys detected 2 additional SGCN butterflies: Aphrodite Fritillary and Monarch. We also completed one vegetation survey per stand between 15 July and 20 August.
