RT Journal Article SR Electronic T1 Restoring Midwestern Viola species for regal fritillary butterfly recovery JF Native Plants Journal JO NATIVE PLANTS JOURNAL FD University of Wisconsin Press SP 129 OP 133 DO 10.3368/npj.15.2.129 VO 15 IS 2 A1 Nyberg, Alyssa A1 Haley, Hilary YR 2014 UL http://npj.uwpress.org/content/15/2/129.abstract AB Several Viola species found in tallgrass prairies of the Midwestern US are larval host plants to regal fritillary butterflies. Working from The Nature Conservancy preserves in Missouri and Indiana, we describe 2 methods of obtaining Viola seeds while producing plants for outplanting and for on-site seed increase production plots for upland and wetland Viola species that occur in the Midwestern US. We incorporate these important species into tallgrass prairie restoration projects that ultimately benefit regal fritillary butterflies.
