Wetlands control flooding, reduce erosion, purify our water and provide food and homes for fish, birds and wildlife.

Here are some wild life that you can see in Ontario while walking at a small distance from populated areas.

 

 Trumpet Swan
 Their breeding habitat is large shallow ponds, undisturbed lakes, pristine wetlands and wide slow rivers, and marshes in northwestern and central North America, with the largest numbers of breeding pairs found in Alaska. They come in the summer close to my house.

They prefer nesting sites with enough space for them to have enough surface water for them to take off, as well as accessible food, shallow, unpolluted water, and little or no human disturbance.
The Trumpeter Swan is the largest extant species of waterfowl. Adults usually measure 138–165 cm (54–65 in) long, though large males can range up to 180 cm (71 in) or more. 


Great Blue Heron
The Great Blue Heron (Ardea herodias) is a large wading bird in the heron family Ardeidae, common near the shores of open water and in wetlands over most of North America.

Notable features of Great Blue Herons include slaty flight feathers, red-brown thighs, and a paired red-brown and black stripe up the flanks; the neck is rusty-gray, with black and white streaking down the front; the head is paler, with a nearly white face, and a pair of black plumes running from just above the eye to the back of the head. 

The primary food for Great Blue Heron is small fish, though it is also known to opportunistically feed on a wide range of shrimp, crabs, aquatic insects, rodents and other small mammals, amphibians, reptiles, and small birds. Primary prey is variable based on availability and abundance.

This species usually breeds in colonies, in trees close to lakes or other wetlands. Adults generally return to the colony site after winter from December (in warmer climes such as California and Florida) to March (in cooler areas such as Canada). Usually colonies include only Great Blue Herons though sometimes they nest alongside other species of herons.
 Canadian Goose

The ubiquitous Canada goose is one of the best known birds in North America. It is found in every contiguous U.S. state and Canadian province at one time of the year or another. Canada geese are adaptable to many habitats.
 Trumpet Swan - this bird is at Makenzie Marsh in Aurora Ontario Canada.
Two years ago there were 2 birds last year 2013 we were visited by 5 birds. There is a real show to see them on the lake people are coming and taking picture of them the kids are watching and sometime feeding them with bread.

These birds feed while swimming, sometimes up-ending or dabbling to reach submerged food. The diet is almost entirely aquatic plants. They will eat both the leaves and stems of submerged and emergent vegetation. They will also dig into muddy substrate underwater to extract roots and tubers. In winter, they may also eat grasses and grains in fields.

In the 19th and early 20th centuries, the Trumpeter Swan was hunted heavily, both as game and a source of feathers. This species is also unusually sensitive to lead poisoning while young. These birds once bred in North America from northwestern Indiana west to Oregon in the U.S., and in Canada from James Bay to the Yukon, and they migrated as far south as Texas and southern California. The trumpeter was rare or extinct in most of the United States by the early twentieth century. Many thousands survived in the core range in Canada and Alaska, however, where populations have since rebounded.
 Turtles - these are small turtles that are taking a sun bath. They allow people to take picture of them. When scared they hide in the water.
 Ducks
 Turtle and ducks


Beaver The beaver (genus Castor) is a primarily nocturnal, large, semi-aquatic rodent. They are the second-largest rodent in the world.Beavers are known for their natural trait of building dams on rivers and streams, and building their homes (known as "lodges") in the resulting pond.

The above pictures were taken in 30 minutes at noon. The Park restoration projects in Ontario created a healthy environment for these wild birds and animals to live in the proximity of the populated areas. The existence of them show that the water is clean and the air is not polluted. A lot of people take picture of these birds and animals while taking a walk in Aurora Ontario Canada.

Provincial parks and conservation reserves support the economy by boosting tourism. They are also important for scientific research, environmental monitoring and outdoor education.  Most importantly, they ensure that future generations will enjoy and benefit from the province’s rich natural and cultural heritage.

Liliana Usvat: Slippery Elm has Been Used as Herbal Remedy by Native Americans

Liliana Usvat: Slippery Elm has Been Used as Herbal Remedy by Native Americans

Slippery Elm has Been Used as Herbal Remedy by Native Americans

The slippery elm is native to eastern Canada and the eastern and central United States where it is found mostly in the Appalachian Mountains. Its name refers to the slippery consistency the inner bark assumes when it is chewed or mixed with water. Slippery elm inner bark has been used historically as a demulcent, emollient, nutritive, astringent, anti-tussive, and vulnerary. It is included as one of four primary ingredients in the herbal cancer remedy, Essiac, and in a number of Essiac-like products such as Flor-Essence.

Elms are deciduous and semi-deciduous trees comprising the genus Ulmus in the plant family Ulmaceae. The genus first appeared in the Miocene geological period about 20 million years ago, originating in what is now central Asia.
 
During the 18th and 19th centuries, elm cultivars enjoyed much popularity as ornamentals in Europe by virtue of their rapid growth and variety of foliage and forms

Viticulture


The Romans, and more recently the Italians, used to plant elms in vineyards as supports for vines. Lopped at three metres, the elms' quick growth, twiggy lateral branches, light shade and root-suckering made them ideal trees for this purpose.
 
Ovid in his Amores characterizes the elm as "loving the vine": ulmus amat vitem, vitis non deserit ulmum (:the elm loves the vine, the vine does not desert the elm) and the ancients spoke of the "marriage" between elm and vine.

Medicinal products

Slippery Elm has been used for centuries as an herbal remedy by Native Americans. The inner bark of the slippery elm tree is used medicinally, both internally and topically. Internally, it has been used to treat sore throats and diarrhea, and externally, slippery elm has been used to treat various inflammatory skin problems like wounds, boils, ulcers, and burns.
 
The mucilaginous inner bark of the Slippery Elm Ulmus rubra has long been used as a demulcent.

A demulcent (derived from the Latin: demulcere "caress") is an agent that forms a soothing film over a mucous membrane, relieving minor pain and inflammation of the membrane. Demulcents are sometimes referred to as mucoprotective agents. Demulcents such as pectin, glycerin, honey, and syrup are common ingredients in cough mixtures. These demulcents will coat the throat and relieve the irritation causing the cough. They can be used to treat any type of cough, but are particularly useful to treat dry coughs. Some demulcents may not be suitable for diabetics as they are based on sugar
 
Slippery elm is a tree. The inner bark (not the whole bark) is used as medicine.

People take slippery elm for coughs, sore throat, colic, diarrhea, constipation, hemorrhoids, irritable bowel syndrome (IBS), bladder and urinary tract infections, syphilis, herpes, and for expelling tapeworms. It is also used for protecting against stomach and duodenal ulcers, for colitis, diverticulitis, GI inflammation, and too much stomach acid. Slippery elm is also taken by mouth to cause an abortion.

Slippery elm is applied to the skin for wounds, burns, gout, rheumatism, cold sores, boils, abscesses, ulcers, toothaches, sore throat, and as a lubricant to ease labor.

In manufacturing, slippery elm is used in some baby foods and adult nutritionals, and in some oral lozenges used for soothing throat pain.

The late Euell Gibbons recommended pouring a pint of boiling water over an ounce of the coarsely ground inner bark, allowing the mixture to cool, and then adding the juice of one-half lemon and enough honey to sweeten the brew to taste. Our pioneer forebears treated colds with such a "lemonade" and it was especially recommended for feverish patients.

The outer bark of the slippery elm is reddish brown, deeply furrowed, and quite rough. It can be harvested any time of the year but peels from the tree most easily in the spring (when the sap is running). The juicy inner bark may then be pulled from the outer with little difficulty. Spread the cambium bark out on newspapers in a warm, dry room. Once it has dried, it may be stored (in sealed glass jars) and ground for use as desired.

The generally advised dosage of slippery elm is to take between 4 and 10 grams of the dried inner bark in capsule form three to four times a day.  You can also make a tea by boiling teaspoons-full of loose bark in a cup of water for ten to fifteen minutes, cooled before drinking.  Three to four cups of this tea can be drunk per day.  To use externally, mix coarse powdered bark with boiling water to make a poultice. - See more at: http://happyherbcompany.com/slippery-elm#sthash.mLjRrNGH.dpuf

How does it work?

Slippery elm contains chemicals that can help soothe sore throats. It can also cause mucous secretion which might be helpful for stomach and intestinal problems.
 
 There are no known side effects or safety issues with this plant.

Barks can be harvested with very little damage to a tree, and can even improve the health of a tree, much as pruning does. The most ecological way to harvest bark is to prune smaller branches from the tree using pruning shears or a small pruning saw.  It doesn't take many branches to supply a house with all it is needed for a year.  If larger quantities are needed  might consider taking a whole sapling if the tree grows in abundance and is in a crowded stand already.

To remove the bark from the branches, use the hand pruners to snip off any side branches and spurs.    Then  take a sharp paring knife or pocketknife and peel the bark in thin strips or shavings, much like peeling a carrot.  Be sure to cut deeply enough to get the inner bark, which will be slightly wet and also is usually green in color.  The different layers are easy to distinguish when you are peeling the branches. 

To peel the barks is to lay the branch flat on your cutting surface, and then take the knife and hold it perpendicularly (right angle) to the branch.  Then with a strong scraping motion, scrape back and forth vigorously.  This shreds the bark while it peels it and results in very nice finished product, no further need for cutting.  The shredding breaks up the fibers nicely, which is very helpful when you make medicinal preparations later.

Food

When dried and ground into a coarse meal, the sweetly fragrant and creamy white or pinkish inner bark of the slippery elm can be boiled into a porridge that looks and tastes very much like oatmeal. And, surprisingly enough, modern nutritionists have discovered that, when so prepared, the bark does indeed possess a food value about equal to that of oatmeal.
 
Slippery elm's inner bark, on the other hand, does have its other uses too. When ground to a fine powder, it makes a good extender for ordinary flour and can be included that way in a wide variety of recipes. And back before today's sugar-laden treats were so widely available, small boys were fond of stripping off pieces of this cambium bark and chewing it. Such a "chaw" makes a sweet-flavored, long-lasting chewing gum that both satisfies thirst and supplies a certain amount of nourishment.

History

It is recorded that, during their bitter winter at Valley Forge, George Washington's ragtag Revolutionary War soldiers lived through one 12-day period on little more than slippery elm porridge. And no one, of course, knows how many starving pioneer families scraped through their first winters on the American continent thanks to the same survival rations.
