Pediocactus nigrispinus is "up and flowering" in Kittitas County. A sensitive and monitored species, we don't discuss anything when it comes to location. Fritz Hochstätter gets the credit for resolving the taxonomic misapplication with P.simpsonii. https://t.co/4MQ6hc9p8e

I agreed to perform a Pediocactus nigrispinus population assessment, this morning. It's threatened. Have some mixed emotions about this. Necessary to record the population but the land managers, in turn, do nothing to protect the species. Image from 19 March 2020. https://t.co/EJiV2gFgjp

Was out today in a difficult-to-access geography with the intention of assessing the site's 2019 population of Pediocactus nigrispinus. Imperiled in the state of Washington https://t.co/3KQMRMNtiV) remote refugia shelter the species from collectors and offroad vehicles. https://t.co/eclbvBG7a6

Well...there's been a change in status. It's Pediocactus nigrispinus starting to flower (1 May 2018). It's an endemic now listed as "imperiled" and all location coordinates are redacted. Fritz Hochstätter's work on the genus is still available: https://t.co/BJSLZIaAed https://t.co/gVVbj9jNBP
