  1. Sow grassland seeds from a local source

    A replicated, randomized, controlled experiment in 2012 in a greenhouse in Wyoming, USA (Herget et al. 2015) found that sowing Sandberg bluegrass Poa secunda seeds from a local source resulted in similar survival to that found when non-local varieties were sown. After four months, the survival of Sandberg bluegrass plants from locally sourced seeds (97–98%) was not significantly different from that of plants from non-local seeds (93–100%). In December 2012, wild Sandberg bluegrass seeds sourced from two local sites were sown in 80 pots, while cultivated Sandberg bluegrass seeds from three sources were sown in 120 pots. All pots were filled with sand and peat moss, and watered twice/day. Two weeks after planting, emerged seedlings were thinned to one plant/pot. Plant survival was monitored for four months from December to March 2012.
