[PCA] Isoaltion Distances

[Reilley, John - NRCS, Kingsville, TX]

I don't know if anyone has answered you on this.  In Texas, the Texas Dept. of Agriculture has a document called the Texas Seed and Plant Certification Act and Standards.  In this document, there is among other useful information, isolation standards, limitations on age of generations, and labeling requirements for native plant material.  I'd imagine that most other states have the same thing.  In general, if it's a cross pollinating grass it has a 660 feet isolation requirement for foundation class seed.  If it is a cross pollinating forb, it has a 2640 feet isolation because it is insect pollinated.

Happy Holidays Everyone,

One of our partners is looking for information regarding isolation distances of species. They are trying to set up founder production of the following species and one of the sites a grassland is being installed near by, potentially compromising the ability to grow many of these species. They also want to be sure any hybridization is not occurring among genera ie. Euthamia, Lespedeza and Solidago. If anyone has information regarding these species it would be greatly appreciated!

Euthamia spp.
Solidago Spp.
Schizachyrim scoparium
Panicum virgatum
Andropogon gerardii
Sorghastrum nutans
Tridens flavus
Eragrostic spectablitis
Ionactus linerifolius
Chrysopsis mariana
Lespedesa spp.

Cheers,
Clara
