MANITOBA, WHERE THE SPIRIT LIVES [1]

A book review by Viateur Boutot

"Promoting the enjoyment of nature is a contribution to the mental well-being of humans - a greatly underrated medicine."
(Paul M. Catling, foreword to Orchids of Manitoba)

An inspiring book titled Orchids of Manitoba: a field guide [2], written by a group of authors [3], was recently published by Native Orchid Conservation Incorporated (NOCI), an organization formed in 1998 [4].  Not only do the authors provide a wealth of information about orchids of the Canadian province, they also share their thoughts on orchid conservation. 

The first impression when one handles the book is its most convenient size, a pocket book that anyone serious about finding North American orchids in situ would feel necessary to carry along in a knapsack.  That is not to say that you would feel free to be careless with the book: it is lavishly illustrated with 220 photos so, it should have a place of honor in a collection of orchid books. 

Each genus is introduced with an etymological note (origin of the name), a brief text, and photos. 

Likewise, for each species, the authors provide an etymological note, details about its abundance (or rarity), the habitat, the flowering time, a description, tips for identification, and comments.  Photos depict each species, and distribution maps are included.  One could regret that the authors found it unnecessary to give earlier synonyms for the majority of species since, in the literature, some species were published under different genus names and epithets. 

After the main section dedicated to each of the 36 species occurring in Manitoba, a table of flowering times (between May and September) is presented.  It should prove very useful to those who wish to go out in the field and look for orchids.

History:  The English botanist William Jackson Hooker was the first curator of the Royal Botanical Gardens at Kew.  In 1839 he was the first to record orchids for Manitoba.  He noted that the following species had been observed near Lake Winnipeg: the ram's head lady's slipper (Cypripedium arietinum), the small yellow lady's slipper (C. calceolus var. parviflorum) and the heart-leaved twayblade (Listera cordata). 

By 1909, 19 species had been listed for Manitoba, including the small purple fringed-orchid, Habenaria psycodes (now Platanthera psycodes).  Since the northern part of Manitoba has not yet been completely explored by botanists, it is quite possible that more orchid species, varieties, or forms might eventually be listed for Manitoba. 

In the middle of the 1980s, in the south of the province, Paul Catling found two species that were not known before to occur in Manitoba: the western prairie fringed orchid (Platanthara praeclara) and the Great Plains ladies' tresses (Spiranthes magnicamporum). 

A total of 36 species in 14 genera [5] have been recorded in Manitoba up to now. 

A manifesto for orchid conservation:  If the information about orchids of Manitoba contained in the book already makes it a great contribution to the literature about orchids of North America, we should also be grateful to the authors for providing a most complete review of orchid conservation initiatives in the province.  These actions should be an inspiration to both organizations and individuals concerned with the conservation of native orchids. 

The authors dedicate a few chapters to the conservation of orchids and their habitats in Manitoba and Canada.  Although the examples given are specific to Manitoba, readers interested in the conservation of orchids in their province or state would easily relate to the concerns and the means used to protect the habitats and the populations of orchids therein. 

A most interesting chapter is dedicated to orchid habitat.  The characteristics of the microhabitats (forest - coniferous (Figs. 2, 3), mixed wood, and deciduous; prairie - tall grass and mixed grass; wetlands (Fig. 4); tundra; and disturbed areas) are described and illustrated with photos.

In the introduction to the book the authors note that most orchid species have very specific habitat requirements, and disturbance of their environment might have adverse effects on the population.  The motivation of the authors for writing the book is clearly stated: "To raise awareness of Manitoba's native orchid species and the need for their conservation."  Further, it is stated that "habitat conservation and public education go hand-in-hand". 

The approach privileged by the authors is refreshing.  It goes against an attitude that too often prevailed in the past based on the assumption that the happy few know best what is good for the rest of the humanity.  If we could think that such an elitist attitude is limited to some narrow spirits who live in peripheral areas, away from the centre of the world, one should remember that, even in presumably advanced societies, it has been a too common slant: "field botanists have often jealously guarded the locations of rare flowers such as orchids, keeping them to small networks"[6]. 

NOCI, an organization for the conservation of native species:  The publisher of the book, NOCI, wishes to foster an awareness of native plant species.  In a section of the book dedicated to conservation and biodiversity, the authors mention that the small white lady's slipper (Cypripedium candidum) has now disappeared from some parts of Manitoba [and from all of Saskatchewan] where it was previously known to occur. 

Historically, vast parts of the virgin prairie and wilderness were cleared by early settlers for agricultural purposes.  Later, deforestation and flooding for hydroelectric projects have destroyed habitats and, consequently, the populations of orchids.  In wetlands, habitats have disappeared as a consequence of drainage.  Additionally, the collection of wild orchids depletes orchid populations. 

In Manitoba, the three following orchid species are now considered to be endangered:
1) The small white lady's slipper (Cypripedium candidum)
2) The western prairie fringed orchid (Platanthera praeclara)
3) The Great Plains ladies' tresses (Spiranthes magnicamporum). 

In the foreword, Paul M. Catling stresses the fact that Manitoba has the largest population of the western prairie fringed orchid (Platanthera praeclara) left in the world.

Manitoba and Indiana:  For orchidophiles living in Indiana, the book should prove to be a useful tool since 20 of the 36 orchid species found in Manitoba also occur in that Midwestern US state.  Of course, Indiana orchid aficionados have been blessed with Michael Homoya's excellent book, Orchids of Indiana, published in 1993 [7], but the book from the Canadian authors should be most interesting and of great assistance to both orchidophiles and specialists in field excursions, even in Indiana.

It would be nice if such a valuable book as Orchids of Manitoba: a field guide would be available for each Canadian province.  Hopefully, scientists from elsewhere in North America will soon produce such treatments of our native orchid species as Michael Homoya did for the US state of Indiana [8].  Providing knowledge of the latter may be one of the best contributions one can make to their conservation. 

Readers will realize that the book is not only a useful tool to learn more about native orchids but also a strong manifesto that encourages a dynamic attitude toward the conservation of orchid species.  Everyone concerned with the conservation of wild orchids in North America should read this book. 

The native orchid conservation spirit is alive and well in Manitoba.  Let us be inspired !

1. The name Manitoba may be derived from the Ojibwe word manitobah or the Cree word manito-wapow.  Both these terms make reference to the Lake Manitoba Narrows as the strait of the spirit.  The accepted lore is that the roaring sound produced by waves breaking on the shores of the narrows was a spirit or manito beating a drum.  In aboriginal culture, a manito is a supernatural power that permeates all things and is present in all aspects of nature - at times taking on the role of guardian or spirit helper."  Source: http://umanitoba.ca/manitoban/2004-2005/0915/article.php?section=culture&article=03

The authors indicate: "We have two separate varieties in two of these species for a total of 38 varieties of orchids" (p.10).  The list titled `Flowering times for Manitoba orchids' contains 36 names, including Cypripedium parviflorum var. makasin and Cypripedium parviflorum var. pubescens (pp.146-148).  In the section `Species Accounts', the authors mention that two varieties of the species Corallorhiza maculata (var. maculata and var. occidentalis) occur in Manitoba (page 65).  [Editor's note by ER: the authors regard Listera auriculata as being present in Manitoba and yet, for the most part, ignore it;  two paragraphs in the Listera genus account explain the situation.]
