Current Crater Lake Botanists: Peter F. Zika


<< Previous | Table of Contents | Next >>

The historical plant lists compiled by Wynd and Applegate were recently updated and expanded by Peter F. Zika, who began park survey work through the Oregon Natural Heritage Program during the summers of 1994 and 1995 (P. Zika, pers. comm.). Additional field work and examination of herbarium specimens led to “A Crater Lake National Park Vascular Plant Checklist.” Published through the Crater Lake Natural History Association, Zika’s list documents 682 species, including locations. The publication lists the narrow endemics of Crater Lake and the Park’s immediate surroundings, including Botrychium pumicola, Collomia mazama, and Ribes erythrocarpum. Other southern Oregon endemics found in the Park include Arenaria pumicola, Castilleja applegatei ssp. applegatei, and Polygonum cascadense. Species that have not been seen since early collections are noted, providing botanists the opportunity to search for them (Zika 2003).
