TY - JOUR T1 - A low-cost modification to a Flail-Vac Harvester for collecting lightweight, wind-dispersed seed JF - Native Plants Journal JO - NATIVE PLANTS JOURNAL SP - 103 LP - 108 DO - 10.3368/npj.17.2.103 VL - 17 IS - 2 AU - David B Simonson AU - Derek J Tilley Y1 - 2016/06/20 UR - http://npj.uwpress.org/content/17/2/103.abstract N2 - Indeterminate wildflowers with pappus-bearing seed are difficult to effectively harvest at yields approaching maximum potential using traditional equipment. We modified a Flail-Vac Seed Stripper by mounting heavy loops of chain to the front of the Flail-Vac to provide agitation of the floral canopy to disarticulate seed from the flowers of hoary tansyaster (Machaeranthera canescens (Pursh) A. Gray [Asteraceae]). The modification allowed for multiple, non-damaging harvests that collected only shatter-ready, fully ripe seed. Labor and time associated with post-harvest drying and seed cleaning were reduced because of the decrease in vegetative matter accumulated. ER -
