Field testing provisional seed zones for basin wildrye

Status: 
Action
Dates: 
April, 2013

In the effort to use genetically appropriate plant materials for restoration projects, provisional seed zones were developed as one method of pairing seed sources to restoration sites. 

Provisional zones were developed through grouping similar climate parameters across broad geographic areas without regard to species specific performance or genetic information. As such, they function as a tool for identifying similar climate envelopes which may serve as an acceptable interim surrogate for species specific genecological work in pairing seed sources to restoration sites. 

Basin wildrye (Leymus cinereus) is a common Great Basin restoration grass for which no species specific seed zones have been developed. In this study we test whether 27 native populations collected from four provisional seed zones in the Central Basin and Range (covers parts of Nevada, Utah, Idaho, and California) demonstrate a home court advantage when planted on four test sites, each representing a provisional seed zone. Four basin wildrye cultivars are included. Our metrics include emergence and survival through the first two growing seasons.

This project is ongoing.
