Checklist

Introduction

This checklist has been done from 10 field surveys from late 2009 and to early 2015. Two additional field surveys have not yet been processed. A new search for vouchers needs to be done, since the current voucher list was produced in 2009.
Checklist for Collins Valley Area

Notes on the Scientific Names Used At This Site and
Information about the links from the Scientific Name and Common Name.

An asterisk before the common name indicates a non-native species.
The other column headers are:

Fam: the first three letters of the plant family name.
#V: the number of vouchers for this area, with a maximum value of 9. The vouchers were obtained in late 2009, so will be missing vouchers present in the Consortium after that date. We'll redo the voucher search in the future.
The column #Pl gives the number of plants observed in four separate areas:

IV: Indian Valley / Cougar Canyon
SC Sheep Canyon
CV Collins Valley along road to Sheep Canyon
LW Lower Willows Loop from Third Crossing via Boulder Alley / Coyote Creek

Version for printing, without lines and other text on this page: html (10 pages) or pdf Clickbook booklet (2 double-sided pages). (See printing instructions for an explanation of these options)
Special version for printing that includes just the species found in the Lower Willows Loop: html (5 pages) or pdf Clickbook booklet (1 double-sided page)
