The Almighty Lawn

“An old error is always more popular than a new truth.” -  German Proverb

In 2006 the American lawn reached a higher status among its citizens - it became the country’s largest irrigated crop. Between our golf courses, sports fields, town squares and residential lawns turfgrass now covers an amazing 40 million acres, or 80 percent, of non-farmed land. Once utilized by the rich as outdoor carpet and by atheletes for sport, turfgrass is now the norm for all residential lots, rural or urban, and the maintenance practices that come with it are now the standard protocol.

Lawns have their roots in the gardens of England but it was not until the post-World War II building boom that it reached its full power here in America. At that time, subdivisions sprouted up around major cities, forming suburbs. To match the prestigious look of larger estates, planners designed large lawns to attract clients. Thus, the goal of making private properties park-like began and fences were not erected to allow for open appearences in residential communities.

Although the 1/2-acre area of grass that is carefully manicured by its owner seams rather harmless, it is the large-scale ramifications of millions of such owners that prove to be devastating. In 2005 it took 238 gallons of water per person to irrigate 40 million acres of turfgrass, which are being mowed with 800 million gallons of small engine gasoline and kept green by 70 million pounds of chemicals.  All this costs an estimated 30 billion dollars annually (2005). The effects on water and air quality are staggering as are the 68,000 injuries sustained annually while mowing.  

Typical Lawn PracticeMartin Quigley, an urban landscape specialist with The Ohio State University states this about lawns: “Turf maintenance is unquestionably the single most labor intensive component of the constructed landscape. Lawn upkeep, though expensive, requires few decisions and little risk. It is not attuned to the peculiarities of individual sites.” Nationwide, the same grass types are used regardless of soil type, climate, topography or regional customs. The turf industry has developed stronger more desirable strains in order to please the 80% of adults that maintain turfgrass.

Oddly enough, lawn care advertising confirms that most residential lawn care is a losing battle against climate, pests, traffic and other variables, unless more efforts, including watering and chemicals, are applied to the cause. The 70 million pounds of chemicals applied to turfgrass annually represent a higher concentration of chemical input than any other form of agriculture worldwide. In Ted Stienberg’s book, American Green: The Obsessive Quest for the Perfect Lawn, he calls the rise of the lawn “one of the most profound transformations of the landscape in american history.” 

Today, we mow most land that is mow-able and any area that is not mowed is considered “weeds.” Dead spots in lawns are dyed green to disguise imperfections. We spend an average of 40 hours per year mowing or pay services an average of $1,080 to mow for us. We pay higher water bills during hot summer weather to keep the grass alive and we spend used car prices for lawn mowers. Lawn clippings represent the largest agricultural byproduct in the U.S., which could support 20% of our nation’s fuel demands if converted to ethanol (David Blume). The Scotts® Miracle Gro Company (SMG on the New York Stock Exchange) now sells bird seed to supply birds with food that the lawn lacks…Odd indeed.

There are many alternatives to battle this consumptive and environmentally un-friendly practice, including: planting areas with native grasses and flowers, installing ”no mow” turf species such as Buffalo Grass, reducing the amount of lawn that is mowed, or promoting urban planners to develop cluster housing which consolidates housing allowing for more open space. The long term cost savings of utilizing lawn alternatives are staggering and should be encouragement alone. The real benefit, however, lies in the increase of habitat, stabilization of soil, use of local materials and weekends that you don’t have to worry about the lawn.

Bobcats

Lynx rufusRecently, a bobcat was sighted within the city limits of Galena, ILL. This serves as a reflection of the status of the bobcat population regionwide. The last two decades has seen a surge in the population, especially in Northwest Illinois and adjacent Iowa.

The Bobat (Lynx rufus) was once a contemporary of bison, elk, and wolves in the wild pre-settlement times. The changing of the landscape to agriculture and bounty killings in the 1800s led to plummeting populations. High pelt prices, indiscriminate killing and little government protection in the 1900s continued this trend. In the 1980s the Bobcat was thought to be absent from the agricultural Midwest. During the late 1970s Illinois and Iowa placed the Bobcat on their lists of state-threatened species. During the 1990s sightings became more common and by 1996 92 of Illinois’ 102 counties had at least one reported sighting. The Bobcat was removed from the threatened species list in Illinois in 1999 and from Iowa’s in 2003. Iowa is currently conducting its first Bobcat trapping season this fall in over three decades. Wisconsin, always having a stable population in the Northern half of the state, is now experiencing common sightings in the Southern half.

Why is this happening? There are several reasons. First, popularity of trapping and pelting has decreased as has the pelt price for Bobcat. The average pelt price in 1982 was $70.67 in 2003 that price had dropped to $67.23. That has left little encouragement for the trapper. Secondly, several states banned the sport including Illinois, Iowa and Indiana allowing the population to rebound. Third, the threat of Bobcats to farmers has decreased as farms have become less diverse. Fourth, land use has changed as more goverment programs are available to create wildlife habitat and more recreation grounds are purchased.  Therefore, the Bobcat can increase its range.

The driftless area offers great habitat for Bobcats. Its steep ravines with small caves offer excellent den opportunities and shelter. Early winter offers the best time to see and hear Bobcats. The males begin to squall and yowl to gain attention of passing females during the night during upcoming mating season. With open woods and a cover of snow one must keep their eyes peeled to catch a glimpse of the wild cat of the Midwest.

The Passenger Pigeon

Passenger Pigeon IllustrationThere are parts of our living world that are in such great abundance that it is difficult to imagine without it. Consumables such as air and water could fall in this category; but how about living creatures. How about the American Robin, the most common bird in North America. Do you think it could ever vanish and go extinct? Probably not but this is exactly what happened to the Passenger Pigeon (Ectopistes migratorius) 100 years ago. Once the most numerous bird in our hemisphere it became extinct within 100 years of human intervention and it may be the only species in which the exact time of extinction is known. 

The Passenger Pigeon once had flocks so large that it would darken the sky for hours as they passed. It comprised 40% of all birds that existed in the 1800’s. The nesting colonies covered as large as 850 square miles of forest. A bird population that has no comparibles, it is hard to fathom these large quantities today. Many factors contributed to the demise of the Passenger Pigeon which included: Hunting for it’s food, using it as fertilizer, shooting for sport, habitat destruction and disease. Many creative and cruel methods were used to kill the bird as it began to harm valuable crops when agriculture came to the frontier.

The last Passenger Pigeons to exist in the wild were at Babcock Wisconsin 1899 and Pike County Ohio where it was eliminated on March 24, 1900. Martha, who was held in captivity at the Cincinati Zoo died at 1:00 P.M. on September 1st 1914. At that time it joined the ranks of many others living creatures to become only an American memory.
