COVID-19 and the SNRS

Updated 4/20/2020

The following represents current guidance for the UC Merced Natural Reserve System. We reserve the right to cancel any reservation to protect the health and safety of visitors and staff, and to revise policies in the event of specific campus, state, NRS, NPS, or CDC guidance.

Yosemite Field Station: 

  • All visits are cancelled through the end of April, 2020.
  • In April, and pending resolution of the statewide "shelter-in-place" order issued by Governor Newsom, we anticipate allowing only visits that support essential research (i.e., place-based scholarly activities and programs that cannot reasonably be conducted elsewhere or rescheduled for a later date). Any essential research visitor groups must be 10 or fewer people. Approval is subject to the availability of housing that can allow for appropriate social distancing while staying at the field station.
  • Processing of all *new* reservations for May through August 2020 is on hold, as we develop our plans for allowing future use of the field station. We will issue updated guidance for May and beyond as the situation evolves.

Sequoia Field Station:  The field station remains closed for the winter, but re-opening may be impacted by COVID-19.

Any queries about SNRS reservations can be directed to Breezy Jackson,, (209) 628-5758.
