All of the grass seed used was local source (yellow tag, non-varietal) or an appropriate local cultivar if non-varietal was not available. All of the forb seed was collected from our burned native prairie remnants from the previous growing season. The species present now are so much greater than what we seeded in 1993, some came in from the native remnants interspersed in the 1993 seeding area. 3 orchid species are now present when none were planted originally, took about 13 years for the Small white lady's slipper to appear outside of the native remnants. Given a chance, nature will fill in the blanks, the seed dispersal mechanism for some of the prairie species is quite amazing. Also planted some Bur oak here in the early 1990's, native to this area but not this farm. My goal of having a bit of oak savannah is 35 years in the making !!
