Abstract:

Slickspot peppergrass (Lepidium papilliferum) is a rare annual or biennial mustard species endemic to southwestern Idaho. Slickspot peppergrass has been a high priority conservation concern in Idaho for many years. The Idaho Conservation Data Center (IDCDC) manages spatial and tabular data pertaining to slickspot peppergrass using element occurrences (EOs). The objectives of this project were to apply the following tasks to all slickspot peppergrass EOs in the IDCDC Database: 1) update and review EO specifications and EO rank specifications; 2) update spatial data; 3) delineate EOs using EO specifications; 4) update and review tabular data; and 5) apply EO ranks based on EO rank specifications. EO specifications and EO rank specifications were developed and applied to all slickspot peppergrass EOs and sub-EOs. After application of the EO specifications and EO rank specifications, there are 101 EOs with the following ranks: B=16, BC=1, C=26, C?=5, D=19, D?=1, E=8, F=9, H=7, X=5, and X?=4. Changes to EOs and EO ranks are summarized. This report establishes a standard for slickspot peppergrass EOs and EO ranks.
