A Guide to the Geology & Landforms of Grey & Bruce Counties

Sunday, May 3rd, 2009

A Guide to the Geology & Landforms of Grey & Bruce Counties s  The aim of this book is to present an over-view of this subject that will be intelligible to anyone interested in this unique area. Geological formations are described first, followed by glaciation and landforms resulting from the ice age. Lake features are outlined and there is a chapter on karst formations, followed by an outline of post-glacial formations created by wind and river action.

Grey and Bruce counties are in an unusual position in Ontario, sandwiched between Lake Huron and Georgian Bay, dominated by the Niagara Escarpment and the tilt of the Michigan Basin. There are many Areas of Natural and Scientific Interest (ANSI’s) related specifically to Geology. A Geology and Landform site map with ANSI locations is included. There is also a map of the Physiography and a third of Bedrock Geology. In the appendices, locations are identified where specific features can be viewed

A Checklist of Vascular Plants for Bruce & Grey Counties

Sunday, May 3rd, 2009
This is the definitive checklist of vascular plants for Bruce and Grey counties listing 1447 taxa (species, subspecies and hybrids) for 136 families, including 72 provincially rare. It is the only publication identifying all locally rare plants in Bruce and Grey counties, as well as provincially rare.

The two counties have been divided into three zones: Bruce Peninsula(p), Southern Bruce(b), and Grey County(g). Species presence in those zones is noted by the letters pbg in a superscript. Upper case PBG indicates very uncommon, and bolded upper case PBG indicates local rarity. Marginal symbols indicate the following categories: naturalized – non- native in Ontario; naturalized but native in Ontario; cultivation escapes; provincially rare in Ontario (NHIC); historical record.

This is an essential reference for botanists, life science inventory specialists, land use planners, resource management agencies, and consultants that are working on projects within Bruce and Grey counties.

The Asters, Goldenrods & Fleabanes of Grey & Bruce Counties

Sunday, May 3rd, 2009

The Asters, Goldenrods & Fleabanes of Grey & Bruce Counties s This book was conceived when two members of the Owen Sound Field Naturalists, Ralph and June Krueger, were having trouble with identification because there are so many species in Ontario. They were developing an Aster and Goldenrod garden. They were using John Semple’s books for Ontario which are excellent but we have only half the Ontario species. We were very fortunate that John gave us permission to use his diagrams. We did not attempt to give colour photos since asters are enormously variable. Some species range from white to dark blue so you have to go by the structure of the flower head and the leaf shape and arrangement.

The Fleabanes (Erigeron sp.) were added because another member of the Field Naturalists, Dorothy Kings, pointed out that people often confuse them with asters. There are only three species and one important rare sub-species – Provencher’ s Fleabane – which is the one illustrated on the front cover of the book. There are 15 aster species and 16 goldenrods (Solidago sp.). All these plants are members of the family which used to be called Compositae because the flowers are actually heads of two different kinds of tiny florets, the outer ones with rays , the inner ones tiny discs. The Fleabanes have narrower ray florets and more of them than the Asters. The diameter of the disc is wider in relation to the length of the petals. The goldenrod flower heads are generally much smaller and more numerous. The number of florets is much fewer.

New England Aster is a typical example of the Asters but its colour varies from pink to purple. The most familiar Goldenrods are three species in the Canada Goldenrod complex, but Grass Leaved Goldenrod with a flat topped inflorescence is also common. Whereas species like the Ontario Goldenrod, photographed on the Flowerpot Island shore, are much more habitat specific and, therefore, uncommon. Because Goldenrods bloom late in the season, many people think they cause Hay Fever. They do not have wind borne pollen, they are insect pollinated so they have sticky pollen. It is the inconspicuous, greenish ragweed, common along mown roadsides and other disturbed areas which is the culprit.

Most people are unaware that one goldenrod has white flowers. Unfortunately, its common name is the Upland White Aster! It is actually a member of the Goldenrod genus, Solidago ptarmicoides. Purchasing this slim volume will enable you to start to recognise the different species you encounter. stores.

Rare & Endangered Species of Grey & Bruce Counties

Sunday, May 3rd, 2009

Rare & Endangered Species of Grey & Bruce Counties
This book is a guide to the provincially rare, vulnerable, threatened and
endangered species of  vascular plants and vertebrates known to occur within
Grey and Bruce counties.  Eighty-seven species are described in detail.
Mention is also made of several other provincially rare species for which
historical records exist, are likely introduced, or the record is
unconfirmed.

Grey and Bruce is home to a great variety of naturally occurring habitats,

some of which are provincially rare.  For a number of reasons, some of the
species that inhabit these Grey and Bruce counties are also provincially
rare.  All of these species are important components that contribute to the
area’s overall high biological diversity.  It is extremely important that we
properly manage these habitats to ensure healthy ecosystems for us all.The four ranking systems that are applied to wildlife in Ontario are
described in detail. This includes definitions for each category of global
rank – G1, G2, G3; COSEWIC status (special concern, threatened and
endangered); provincial or sub-national rank (SRANK) – S1, S2, S3; and MNR
status (vulnerable, threatened and endangered). [See sample page]. This
ranking is provided for each provincially rare species showing known
distribution and sources for reference at the time of printing in 2004.
Species status often changes, so it is always best to check with the Natural
Heritage Information Centre (Ontario Ministry of Natural Resources) to
determine current designations.
Detailed information is provided for 7 fish, 5 reptiles, 14 birds, 1 mammal,
and 58 plants. Also included are the Butternut tree and the Monarch
Butterfly, that have been common until recently, but are species of
increasing concern. The information provided for each species includes an
explanation as to why the species is in decline, local distribution, local
habitat, behaviour, and a detailed description for identification purposes.
Also included is a drawing or photo of each species, a  geographic township
map showing known distribution, sources for further reference. Readers are
encouraged to report any sightings of provincially rare species to the
Ontario Ministry of Natural Resources (Natural Heritage Information Centre).This book is available from the Ginger Press <maryann@gingerpress.com> and
other local book stores.

A Guide to the Ferns of Grey & Bruce Counties

Sunday, May 3rd, 2009

A Guide to the Ferns of Grey & Bruce Counties Fifty ferns have been recorded from Grey and Bruce counties, two thirds of the fern flora of Ontario and only two fewer than the number found in the British Isles. Although the number is not great, people find them difficult to identify since they are all green and have no flowers.

The first identifying feature to view is the shape of the frond (leaf). In a few ferns the fronds are entire. A good example of this is the Hart’ s Tongue Fern. This is globally rare as, in North America, it is only found in any quantity in this area of Ontario, especially along the escarpment. There are a few remnant populations in the States. It is related to the much more common Hart’s Tongue found in Europe but, separation for thousands of years – probably by glaciation – has caused the North American population to develop into a separate sub-species.

In the picture of the Hart’s Tongue Fern, another fern can be seen just left of the centre which has the blade of the frond divided into leaflets. In ferns, these are called pinnae (singular – pinna). We refer to these ferns as once divided. This is the Northern Holly Fern so called because the pinnae are stiff and feel prickly. Another example of a once divided fern is the Polypody. This is not too common in this area as it flourishes in more acid situations but it will grow on a rock if it is covered with a good layer of humus and mosses.

The Walking fern is also an example of a fern with an undivided frond. In this case, they are very tapered and have the ability to root at the tip. Consequently, it forms dense clones. These are only found on the top of large dolostone blocks in this area.

In the Sensitive Fern the pinnules are indented but not quite divided into sub-leaflets. The Sensitive Fern is named because it is extremely sensitive to frost so that its fronds are one of the first to die and shrivel up at the beginning of autumn. In some ferns the second division is complete and the pinnae are divided into pinnules. We refer to these as twice divided. The Silvery Glade Fern is an example of this and so is the Virginia Chain Fern.

In some ferns the pinnules are further sub-divided into lobes and these are said to be thrice divided. A common example of this type of lacy fern is the Spinulose Wood Fern found in swampy forest. The Evergreen Wood Fern is similar but is found on drier forest floors, especially at the base of trees. Its fronds stay green all winter, even under the snow. The Lady Fern is also thrice cut. It is difficult to separate them until you turn them over and look at the way the sporangia (spore producing organs) are housed in the indusia. In the Spinulose and Evergreen wood ferns the indusia are little dots, in the Lady Fern they are slits which form chevrons. In the photo of the Virginia Chain Fern we are looking at the underside of the frond and we can seen the indusia tightly packed along the midrib.

There is a great deal of variation in the spore bearing organs of ferns. In some cases, like the Cinnamon Fern on the front cover of The Ferns of Grey and Bruce , the fertile frond is a totally different structure from the sterile fronds. The Cinnamon Fern is so named because the colour of the spores makes the fertile frond look like a cinnamon stick. The Sensitive Fern also has a different kind of fertile frond which remains erect and shedding spores all through the winter after the sterile fronds are long dead. In some cases, the fronds are part sterile and part fertile. The Rattlesnake Fern is an example of this. The fertile portion can be seen rising above the low-lying sterile parts.

These variations provide a means of separating the different species so that they can be identified. It is challenging but The Ferns of Grey and Bruce explains this fully and the illustrations, frond silhouettes and colour pictures facilitate this. There are only 50 species! Hunting for ferns will lead you into a variety of interesting habitats and give you a different view of the natural world.

Exploring An Urban Forest: Owen Sound’s Heritage of Trees

Sunday, May 3rd, 2009

Exploring An Urban Forest: Owen Sound’s Heritage of Trees
The aim of this book is to encourage people to recognize the trees
surrounding them. With greater appreciation, an understanding of their
importance to the community will develop and, hopefully, this will encourage
residents in the future to make every effort to maintain this urban forest
in a healthy condition.

The book includes sections on the history of the urban forest and its
values, how this project began, and the relationship of Owen Sound’s urban
forest to the natural forest regions of Ontario.

Some 87 trees and large shrubs are described, of which 41% are not native to
North America; 10% are Carolinian; 6% are native to North America but not
native to Ontario or the Carolinian Forest; and the remaining 43% are native
to Grey County. Many publications are currently available to help readers
identify native species, but very few are available to identify non-native
or introduced species which are typically found in urban areas such as Owen
Sound. This makes this publication very useful and not only in Owen Sound.
Most cities in eastern North America have planted the same species.

There is a written description of each species. Key identification features
are bolded. Background information is given for each tree such as uses of
the wood, how named, and preferred habitat. Sometimes specific addresses are
provided where good examples can be seen. Also included with permission are
many photos and line drawings of leaves, needles, fruits, flowers, etc. from
“Native Trees of Canada” by Hosie and “Trees in Canada” by Farrar.

An identification key has been developed for the book to allow
identification to be undertaken in a systematic way.

Another attribute is the inclusion of 4 walking tours of Owen Sound. These
are complete with detailed maps and street names and addresses where
excellent examples of the various tree species can be seen first hand. All
trees can be viewed from the street without infringing on the privacy of
residents.

This book is available from the Ginger Press >maryann@gingerpress.com> and other local book stores.

First Book of Ontario Wildflowers

Sunday, May 3rd, 2009

First Book of Ontario WildflowersThe First Book of Ontario Wildflowers is self-published by an Owen Sound Field naturalist member – Joan Crowe. Three other club members contributed photographs – Marg Gaviller, Merle Gunby and Walter Crowe. Three photographs taken by the late Lottie Chapman, who was a long time resident of this area, were also used. In all, 180 species are described with colour pictures and another 90 species mentioned. This is a very small proportion of the total list of flowering plants for Ontario.

The aim of this book is to help those newly interested in wildflowers to find out how to tackle the job of identification in a systematic way by learning the features that have to be examined and, also, to begin to understand how plants have been grouped into families by botanists. Approaching the subject in this way, enables the mind to cope with the diversity and complexity of the plants one encounters.

Consequently, many of the flowers described in this book are non-native species that beginners are likely to find along roadsides and in other disturbed areas, for example, flowers such as the clovers and buttercups, Chicory and Wild Carrot. The importance of Latin names is emphasized and the confusion that can be created by common names is pointed out.

There are also many relatively common native species included that are found in a variety of habitats throughout Ontario. Some species that are classified as rare, either provincially or globally have also been described. Particularly in our area, it is not difficult to find flowers such as the Dwarf Lake Iris or the Lakeside Daisy which are said to be rare because they are endemic to this area and are not found elsewhere.

The introductory sections provide general information about orchids and how to identify them. A key for identifying the listed species is included, as well as a table of the species in order of flowering time. This book will also be useful in most parts of Ontario and adjacent states. It was reprinted with a few revisions in 2005.

The book has a spiral The book has a spiral binding so that it is easy to open in the field and the pages stay flat. Hopefully, by using this introductory book, interested naturalists can go on to develop their skills and be able use more advanced books.

Orchids of Grey and Bruce Counties

Sunday, May 3rd, 2009

Orchids of Grey and Bruce Counties
This 105 page publication has a full page for each of the 48 species that have been reported from Bruce and Grey counties. These pages have anecdotal information as well as a systematic description of the plant and its habitat, accompanied by diagrams of the plant and the individual flower. Shown here is the page for the Calypso orchid. The format is the same for all species. In addition, the book has a centre section with a colour picture of each flower taken by the late Dr. Donald R. Gunn and reproduced by courtesy of the Royal Botanical Garden.

Bruce and Grey counties are a unique area, with the Niagara escarpment running throughout. Georgian Bay is on one side and the main body of Lake Huron on the other. The high calcium content of the escarpment rocks dominates the soils and wetlands. All of these factors combine to create a variety of habitats suited to the 48 species of orchid that have been recorded. This is over two thirds of the Ontario list and one more than the number found in the whole of northwestern Europe.

Visitors to this area most often first notice the Yellow and the Showy Lady’s Slippers growing along the roadside in late spring. Another Lady’s Slipper, that is much less common, can be found in shaded locations near Lake Huron on the west side of the Peninsula, usually in the last week in May. This is the Ram’s Head, so called because the shape of the flower is reminiscent of a charging ram.  Soon after the Lady’s Slippers a number of orchids start to appear in the fens along the Lake Huron shore. One of the most striking is the Bog Candles, a tall spike of small shining flowers rising from a watery bed. Even more amazing is the colour of the Grass Pink. If you look carefully, you will see that the lip of this orchid is at the top, unlike all the others. The reason is that this is the only species that does not twist during its development.  A little later comes the attractive Rose Pogonia. Fairly common in swampy areas or wet meadows, sometimes even in roadside ditches, is the Small Purple Fringed Orchis with its cluster of dime-sized bright pinkish-purple flowers. It can be found in flower from June to mid-August.  Mostly much later in the season, in a variety of habitats from fens to more wooded areas, the Spiranthes or Ladies Tresses appear. There are several species which all have a spike of small cream coloured flowers which characteristically twist round the stem – hence the common name.

Orchids are the most highly evolved group of flowering plants. Not only are they completely dependent on associated fungi, which was the reason horticulturalists took so long to work out how to grow them from seed; but they have also evolved in tandem with insects. They are dependent on them for fertilization. There are various strategies to achieve this but, in some, the flowers actually mimic insects and these are often not brightly coloured. The Broad Lipped Twayblade is a good example of this, as it resembles a whitish moth.
Orchids produce millions of tiny seeds. Air samples from the Arctic contain orchid seeds, but they will only grow in company with their symbiotic fungi and in exactly the right environmental conditions. For this reason, if you wish to grow native orchids you should obtain them from a native plant nursery. On no account should they ever be transplanted from the wild. Purchase ’ The Orchids of Bruce and Grey and then come and enjoy finding them in their native habitat. Remember to tread lightly and leave everything as you find it, especially if you are taking photographs.
