The Natural World Article By Earthyman From Ion Exchange, Inc.

The natural world, as recognized over and over again can be our best teacher. The struggles and stresses that we perceive in our daily lives can get to be such a drain on us. When this happens, our lives are no longer in cadence or harmony with others and the natural world. We start to feel distressed and lost while even armed with our fine educations, years of therapy, self-awareness and physical fitness. Where do we turn? There seems to be no answer and no one to help us.

I remember when I was very young and my parents used to argue with each other, I would get very upset and walk out of the house. There was an old red oak stump in our timber. I would just sit there, staring at the ground and trees around me. It was my escape and my haven from stress and turmoil. This little wood lot that had been so mistreated and now barely remained had become my friend and companion. Having been stripped of all valuable timber long ago, then grazed, then abandoned, now recovering but extremely scarred, the landscape did not complain but only saw new opportunity for change and a new life. The stripping of its timber was not harbored in a memory bank filled with judgments of greed or bad behavior. No one was being held responsible for the condition of this little parcel. Out of what looked like total defilement and desolation came a new beginning and a new life for this old, old piece of ground.

There were Yellow Warblers, Myrtle Warblers, Scarlet Tanagers, Ruby Crown Kinglets, and Purple Finches, over 100 species of beautiful birds in this small haven along with squirrels, rabbits and copperheads. It was amazing that this land, so poor, could house and care for such a diversity of life. Underneath the shallow leaves and humus of the oaks and hickories, it was only 2″ to shale rock. Erosion had not even allowed a new soil to stay in place. Now a new soil was starting to form. The oaks grew ever so slowly, but they grew. Now, down the slope, a small clearing, a little knoll occupied by Andropogon virginicus, or Broom Sedge as we called it, was dotted with Eastern Red Cedars. From here, I could lie down in the grass and look to the south and east to see a whole horizon bounded by the Blue Ridge Mountains. Only 12 miles away, I could see Big Bald Mountain on the North Carolina line marked by the Appalachian Trail. It was a beautiful wilderness within site of this abandoned and forgotten vestige that was once a link and connection to these mighty mountains. Like a child cast out into a desert of chaos and severed from its mother, this little wood lot had become an island. My education and awareness might not have been that well established at the age of nine but my feelings were in tact and I knew this was a place where I could go and start to heal and find comfort. I didn’t have to worry about conflict here. I was accepted and I fit in with the rest. I became part of that landscape and it is still within me. I have learned from the great spirit of the natural world. Every change is an opportunity for a new beginning. Nature does not hear or respond to shame, blame, doubt, and guilt nor does she harbor regrets or grudges. She takes what she has and moves on to constantly create more beauty in the world.

I think it’s time to move on and create some beauty in our world. Won’t you join the natural world

Native Plant Communities Of Iowa Article

By: Howard Bright

The Plant Communities of Iowa are vast but we will limit them to four major communities knowing there are many subgroups of these four.  What is a plant community? In nature, certain species are found growing together and they form specific colonies of plants called  “plant communities”. Native plants always grow in association with others to create plant communities that are essentially associations of indigenous species that have evolved over thousands of years and adapted to the specific geography, hydrology and climate of a particular area. The resulting “communities” are really groups of plants that exist together because of the given environmental conditions. 

Why is it important to know about natural plant communities?  It is very important because we can use these native plant communities as a prescription from nature in designing our wildflower gardens or landscapes.  There are four broad categories of native plant communities here in the Midwest and hundreds of sub categories as we break each of them down into more specific site conditions.  It is important to recognize which one of the four categories you would like to create or reconstruct.  The four major plant communities of the Midwest are: Prairies, Savannas, Wetlands and Woodlands.

When the white man drove deeper through the hardwood forest driving westward until they eventually broke through the dark shadows of trees and the shrubs of that forest land and peered out onto the blinding light of the open prairie, it was a sight to behold waving in the wind and appearing as a sea of rolling grasses dotted with the colors of blooming flowers.  Indeed this was a strange land to these new visitors.  Steeping out onto this sea of grass, the pioneer disappeared and kept moving westward.  This land was covered with Buffalo, Elk, Deer, Bear, Cougars, Prairie Chickens, Beaver and all kinds of wildlife.

It wasn’t long before this land was discovered, occupied and changed forever. In the 1800s, Iowans reworked the face of their new state with a speed and to an extent perhaps unparalleled in human history.  At the beginning of the century, a blanket of prairie cloaked three-quarters of this “land between two rivers.”  Pothole marshes dotted the flatter north-central part of the state, while a network of streams laced the rolling hills elsewhere across Iowa.  Dense forests engulfed some valleys in the east and groves of bur oaks climbed out of the river corridors and onto the ridges to form savannas.

Thousands of Native Americans lived on the land, harvesting wild plants and animals, growing crops, and occasionally managing the vegetation with fire.  By 1900, however, Euro-American settlers had claimed nearly all of Iowa’s 36 million acres as farmland. Non-Indian settlement officially began on June 1, 1833, when pioneers first were allowed to claim new land in the 6-million-acre Black Hawk Purchase along the west side of the Mississippi River.  By 1846, when Iowa became a state, census records listed 96,088 people.  The population doubled to 192,914 by 1850 and topped one million before 1870.  In 1900, Iowa had 2.2 million people, compared to 2.9 million people today.  Most lived on the state’s 200,000 farms, working land where 95 percent of the prairie, two-thirds of the woodlands, and most of the wetlands had been converted to agriculture.  This dramatic, swift, almost complete change of diverse prairie to a monoculture of cropland profoundly altered the ecosystem.  Twenty-eight million acres of bluestem, dropseed, compass plants, coneflowers, gentians, and hundreds other species were transformed, in a relative eye-blink, into a patchwork of corn, wheat, oats, hay, and pasture.  Those plots have expanded to the huge roadside-to-roadside corn and soybean fields that we see today.

Before Iowa was settled a map depicts the vegetation that was present around 1850.  Note the majority of the landscape was tall grass prairie.  There were thousands of acres of wetlands, especially in Central and Northwest Iowa.  The Woodlands were confined to the steep areas along streams and in the Driftless area of Iowa.  Rolling and steeper hills were occupied by Savannas.

It only took 60 to 70 years to almost completely change the ecosystem of Iowa.  It is said that this was one of the quickest and largest annihilations of a natural ecosystem.  Oxen with wooden and steel plows developed by John Deere ripped up the prairie sod and crops were planted.

Glacial deposits occurred over the entire state of Iowa during a period of 2.5 million years and as recent as 10,000 years ago.  The only region not affected by glaciations is northeast Iowa where bedrock is exposed in many areas.

A multitude of events were occurring simultaneously during the last glacial period known as the Wisconsian Glacial Age.  Notably, while the older glaciers of the Nebraskan, Kansan and Illinoinian had long retreated and left their heavy loads across the state, a new glacier advanced from the north covering the north central and central pars of the state.  At the same time huge amounts of silt were blowing in from the northwest from the exposed glacial plains due northwest of Iowa’s western border. Loose materials much younger than the bedrock beneath dominate the present land surface across Iowa. These materials consist of sediment originating from ice sheets, melt water streams, and strong winds during a series of glacial events between 2.5 million and 10,000 years ago (Quaternary). This familiar “dirt” consists of pebbly clay, sand, gravel, and abundant silt, which over time have weathered into Iowa’s productive loamy soils. These easily eroded “Ice Age” deposits account for the gently rolling appearance of much of the Iowa (and Midwestern) landscape.

During the Ice Age, glaciers advanced down into the mid-continent of North America, grinding underlying rock into a fine powder like sediment called “glacial flour.” As temperatures warmed, the glaciers melted and enormous amounts of water and sediment rushed down the Missouri River valley. The sediment was eventually deposited on flood plains downstream, creating huge mud flats. During the winters the melt waters would recede, leaving the mud flats exposed. As they dried, fine-grained mud material called silt was picked up and carried by strong winds. These large dust clouds were moved eastward by prevailing westerly winds and were redeposited over broad areas. Heavier, coarser silt, deposited closest to its Missouri River flood plain source, formed sharp, high bluffs on the western margin of the Loess Hills. Finer, lighter silt, deposited farther east, created gently sloping hills on the eastern margin. This process repeated for thousands of years, building layer upon layer until the loess reached thicknesses of 60 feet or more and became the dominant feature of the terrain.

Even though the prairie is gone, it has left us with a black treasure, our soil.  Over the eons of time the plants that grew on the prairie formed the richest soil on this planet.  Millions of acres are blanketed with black earth known as prairie soils.

What makes soils the way they are?  How did Iowa end up being the most fertile land in the world?   A unique combination and interaction of all of these factors formed our soils.  How are the soils of Iowa different?  By changing just one factor, we affect a major change in the soil.

Factors that interacted to form our soils can be simplified to: Parent Material, Climate, Topography, Vegetation, Time and Human Beings.

Soils are conceived, as we are, from our Parent Material.  Parent materials are composed of the raw earth that lays exposed to the elements. Major parent materials in Iowa consist of bedrock, glacial deposits called glacial till, water deposited material or alluvial deposits, and wind blown silt known as “loess”.  In other parts of the world, soils may be formed in volcanic ash or rock.

Climate has a profound effect on our soils as they are influenced by rainfall, temperature, freezing and thawing, sunlight and day length.

The way the land lays called Topography greatly influences our soils.  From the steep hills along river corridors to the level bottomlands, slope of the land can change the characteristics of our soils.

Vegetation and Organisms dramatically affect our soils.  Within a very localized area, we can note the effect of our past vegetation and what influence it has had on soils.  From the deep rich organic prairie soils developed under the influence of the tall grass prairie to the soils developed under a woodland condition depth of topsoil and fertility vary greatly.

We probably forget about a factor that is ever present and that factor is Time.  It is obvious when we think about the sediment deposited by a river or stream, which is in geologic times, is extremely young.  What a contrast when we sit atop a rock out crop that has been exposed for eons of time.  The stream deposited material stays forever young while the bedrock of a long ago sedimentized ocean bottom gets older and older.  Soils can’t hide their age either.

On the recent geologic scene came Humans and they have now joined the forces of soil forming factors.  By plowing, the natural vegetation and protection of the soil has been removed increasing erosion to an alarming rate.  Topsoil is destroyed, texture of the soil, which allows infiltration of water, is altered, soil forming organisms are eliminated, fertility is diminished as organic matter is washed away and soil tilth is destroyed.  Man has and is having his influence on our soils.  Fallow land and row crops now occupy land that was once a lush sponge to absorb water and cleanse it.

Once we understand the importance of our geologic past, recent history and soil forming factors, we can start to put together nature’s puzzle.  This intricate puzzle laid down over the eons is now at our fingertips for those who pay attention.

What other questions do we need to ask to get this right combination of plants that will fit our site?

  • What direction is your site facing, called Aspect?  A north and northeasterly direction may receive much less sunlight on a steeper slope than those facing south or west on the same steepness of slope due to the angle of the sun.
  • Is your site level, rolling or steep?  Slope as a steep south slope may be hot and dry while a steep north slope may be cool and moist.
  • How much Sunlight does your site get?  If it is dense shade versus full sunlight, you will need entirely different plants to suit your situation.
  • What is the condition of the soil in regards to Soil Moisture?  Drainage of the soil can range from saturated to excessively drained.
  • What are the sizes of the particles that make up your soil, called Texture.   It could range from sand to clay which an important characteristic to note as some plants will not tolerate these conditions.  For detailed description of your soils contact your local NRCS office and get a soil survey report of your county.

Absorbing and understanding the characteristics of our landscapes and soils allows us to then classify our sites.  In site classification we will assign a general category to our site based on all the previously mentioned information.  There are basically five sites to consider:

  • Dry
  • Dry Mesic
  • Mesic
  • Wet Mesic
  • Wet

Next we need to decide which plant community we are dealing with.  It may be a pre-existing condition or one that we want to create.  It is usually best to take what nature has given us if we have that opportunity.  However, if you live in an urban area, your site may have been severely altered and you will have to decide what you want to create there.  As mentioned before, we have four categories of plant communities:

  • Prairie
  • Savanna
  • Wetland
  • Woodland

Once the plant community is determined, select the most appropriate species for your plant community.  Now you are using nature’s prescription for success in creating your native wildflower planting.

Lesson Learned from the Land Article

As I mapped soils throughout eastern Iowa back in the early 70’s, it was interesting for me to put together a picture of what the original landscape looked like.  In eastern Cedar County, I came upon some soils that did not fit the general description of prairie or savanna soils in that they were somewhere in between the two. I pondered this as I walked day after day over the land and began to see the picture in my mind.  Savannas are transitions from prairie to a micro climate that favors some tree growth.  There must be all grades of transition but what are they called?  When does a prairie become a prairie as we walk westward out of the timber into the savanna into the “prairie”?  When does a prairie become a savanna?  What is your definition of a savanna?  I don’t think there is a definition or name that can be placed on this “la la land of the past”.  One way to look at these ecosystems is to imagine an interaction not individual influences, although they may be critical.  If we back away in time and peer down from above, we can see a constant winning and waning of movement much like the tides that come and go.

What footprint is left in the soil to give us clues to the past? Certainly visual imprints are evident even though the land is now covered with corn and beans.

John Madson, who wrote Where the Sky Began, so beautifully described his vision of coming out of the timber and seeing, looming in front of him, an open sky and a sea of grass as far as the eye could see.  He made mention of the front line soldiers sent out by the savanna or timber which allowed the advancement of the savanna and timber upon the prairie.  Wild plumb trees were sent out as a front line defense or offense depending upon which the environment favored.  Sometimes the battle would be won by the prairie and other times by the savanna and eventually a total overthrow of one over the other but the soldiers of the front line are always forgotten for they are in this “la la land of transition”.   I was reminded of them that day in Cedar County, Iowa as I observed the grainy grey coats of the now vanished front line soldiers of the savanna who left their mark upon the prairie soil profile.  Were they lost in battle as they succumbed to the forces of the prairie or were they stopped dead in their tracks by the ever- advancing moldboard plow?

I am reminded of my life and how it is much like this ever- changing world that we know as Prairie and Savanna but not a struggle or battle but the ebb and flow with the tides of life.  Just as every component of the prairie and savanna are a part of the total wonderment of creation so are we.  Are we on the frontline of change?  Do we have the courage to move forward regardless of the elements that we face?  The lessons of the land are there for all of us if we just open our eyes and hearts and breathe in the intuitive powers of this great planet.

“Helping you create your own natural beauty”

Earthyman Article: Behold the Natural Beauty but Don’t Compare or Curse the Burdock

In Western traditions we are constantly comparing one thing to the other.  Which do you like better… brown or blue eyes, basketball or football,  chicken or fish?  Nature did not give us all the glorious scenes to judge one place or species over the other.  Why does one thing have to be better than another?   Think about it.  When we compare or try to make one thing better than another, our minds leave the natural beauty of the entity and go to a place of judgement and diminish the innate qualities of that which is being analyzed.

More examples that nature puts before us to admire but get turned around occur in the plant world.   One such example is the Common Burdock, known as a terrible weed, ugly and a plague for horses’ manes and tails.  Soon, a hatred is built up regarding this plant.  What did “The Great Spirit” have in mind when the Burdock was born into existence?  Certainly it is well equipped to survive as the seed heads cling to any thing that brushes up against it .  It is even more tenacious than velcro which by the way was invented as this natural clinging trait of Burdock was copied by man.  Certainly if we were hungry or starving we could dig the roots of Burdock and survive by eating them.

If we look closely to the flower of the Burdock, it holds its own natural beauty but it is not considered as a prize wildflower possession by any landscaper or gardener.  Truly the beauty is lost as we curse the power that the Burdock has over us.  We wage war against it by digging it, spraying it and killing it anyway that we can.  Can we change these natural traits or is “The Great Spirit” trying to tell us something?  When did we start to complain about this plant?  The more we complained, the more we got.  Right?  Nature’s signs go unheeded and the Burdock serves as a red flag that something isn’t right with the harmony of our use of the land.  As an early indicator, it makes itself obvious as we overgraze our pastures and pay no attention to the overuse of them.  Those who heed the warning sign back away and start treating the land with more respect and the Burdock starts to diminish over time.

Burdock is not less than, more than or uglier than.  It just is, so appreciate your football or basketball for what it is and as we adjust our lives to look beneath the surface and accept all diversity as beautiful in its own light.

Monsanto Fails at Improving Agriculture Article

Monsanto Fails at Improving Agriculture

Help UCS Set the Record Straight by Sharing Our New Ad Campaign

Monsanto’s advertisements tell an impressive tale of the agribusiness giant’s achievements: Feeding a growing population. Protecting natural resources. Promoting biodiversity.

It sounds wonderful, but unfortunately, there’s a catch: These claims are often exaggerated, misleading or downright false. Monsanto’s products—and the practices they promote—may sustain the company’s profits, but the evidence shows that they stand in the way of truly sustainable solutions to our food and farming challenges.

In the ads below, we counter Monsanto’s feel-good rhetoric with some facts gleaned from UCS analysis. Share them with friends, and spread the word: when it comes to healthy farming, Monsanto fails!

(Click on the images to see full-size versions.)

#1: More Herbicide + Fewer Butterflies = Better Seeds?

Monsanto Says: “In the hands of farmers, better seeds can help meet the needs of our rapidly growing population, while protecting the earth’s natural resources.”

In Fact: Monsanto’s Roundup Ready crops, genetically engineered to tolerate the company’s Roundup herbicide,increased herbicide use by an estimated 383 million pounds between 1996 and 2008. And Monarch butterflies have laid 81 percent fewer eggs thanks to habitat loss since Roundup Ready was introduced.

#2: A Bumper Crop of Superweeds

Monsanto Says: “Our rapidly growing population is putting limited resources–such as land, water, and energy–under increased pressure.”

In Fact: The challenge is real, but Monsanto’s products aren’t the answer. UCS analysis shows that GE crops have so far done little to improve yields in the U.S. Meanwhile—speaking of rapidly growing populations—overuse of Roundup Ready crops has spawned an epidemic of “superweeds,” causing huge problems for U.S. farmers.

#3: All Wet on Drought Tolerance

Monsanto Says: “With the right tools, farmers can conserve more for future generations.”

In Fact: If farmers want to conserve more water, Monsanto’s DroughtGard corn isn’t the right tool. A recent UCS study found that DroughtGard won’t help farmers reduce water use—and its engineered drought tolerance will likely only be useful in moderate drought conditions. (Research has shown that organic farming methods could improve drought-year yields by up to 96%.)
