Mike Ryan has written a book entitled Plants of the Kamloops Area.   It can be read online and readers can download the book for convenience.  Our thanks to Mike for his work on this.   Here is the first part of the preface:

“This pdf is a preliminary attempt to photograph and describe in non-technical terms the common (and not so common) plants in the Kamloops area. Many botanical treatments and field guides often depend heavily on mature flowers to identify species. This frequently works but there are many times when flowers are absent or have already flowered and it becomes difficult for the field naturalist to know what species they are looking at in the absence of flowers. I have tried for many species to photograph them at different periods during the growing season to show features of the plant not only when they are in flower but also when they are in fruit or have died back for the remainder of the growing season. There is still a substantial amount of work to complete this task as some species only have photos portraying the species during the flowering period and sometimes when the fruiting period. At this point the amount of text is quite minimal and is only included to describe key features of the plant or its habitat and I have tried to keep the technical jargon to a minimum.”   (Mike Ryan)
