Fall and spring are great times to plant.  The weather is cool and rainy, allowing small sprouts to take root and thrive.  If you’re headed up to the cabin this weekend, why not survey your shoreline and think seriously about naturalizing it? It’s easier than it sounds, you’ll love how it looks, and best of all, you’ll be taking a step to make sure your kids and future generations will be able to enjoy the lake in years to come.

Until this summer, my husband’s parents had a grassy, green lawn running from where their cabin stood down to the rocks which had been placed at the water’s edge many years ago.  Many of the rocks were slipping into the lake, and the shoreline was beginning to tumble into the water too.  Their lake, like many, is susceptible to potentially dangerous blue/green algae blooms, and lawns like theirs contribute to the problem, as fertilizer can flow easily from the lawn into the water.

Last year at the state fair, they spoke with someone who told them they might be able to get a grant through the Atkin County Soil and Water District and the Big Sandy Lakes’ watershed project (originating from the Department of Natural Resources) to help them naturalize their lake shoreline, if they were willing to contribute the labor.  They applied and were able to get a grant, work with a landscaper, and replant their shoreline with plants that will slow runoff, reduce erosion, and filter nutrients that can cause algal blooms in the lake.  The plantings are filling in after being planted in July, and they look beautiful!  Many of the plants have lovely flowers (Lupine, Flox, Columbine) and plants like Swamp Milkweed, which grows close to the water, will be butterfly magnets next summer.

A shoreland buffer strip (also called a filter strip or buffer zone) separates your lawn from the lake. It typically includes taller grasses, blooming plants, shrubs and trees, as well as aquatic plants such as cattails, rushes, and lilies.  The work we did involved killing a strip of grass along the lake shore, cutting pieces of wild willow to bind together and stake at the water’s edge, putting natural mesh along the sloped land next to the lake and planting native plants in the prepared area.  The dead grass served as mulch and my in-laws had a planting party for friends and other residents of the lake who were interested in learning about what they were doing.  I think with 12 people, it took about 3 hours to do all the planting.  Not bad for a day’s work.

If that sounds to intense, according to the  University of Minnesota’s Shoreland Management Resource Guide, “The easiest approach to establishing a buffer strip is simply to do nothing. If you stop mowing, weeding, and raking your shoreland area, many native plants will likely reestablish.”  The link above also lists local nurseries where you can buy native plants and suggests who you can talk to about what to plant on your lake.  Or, get in contact with your local lake association to find out whether they have grant money available to help you naturalize your shoreline.

Our cabin still has a mowed green lawn behind the shoreland buffer strip, but we don’t fertilize it and it’s nice to know that someday our grandchildren may swim in cleaner, safer water and catch butterflies in the swamp milkweed by the lake’s edge.

This morning, a friend and I  headed for the Science Museum of Minnesota to see the “greatest archeological find of the 20th century”, the Dead Sea Scrolls.   A Bedouin goat herder stumbled on the first of the ancient scrolls  in a cave near the Dead Sea in 1947.   Eventually, 10 more caves containing scrolls were discovered near the first cave, and near the ancient ruins of a settlement known as Khirbet Qumran.  Later, more scrolls were found in caves around the Dead sea and the Judean Desert.  Altogether, more than 900 scrolls were discovered.

The scrolls were often contained in pottery jars, and though many of the scrolls are damaged, it is astonishing that so many of them are in good enough condition to read, or piece together.  Two thousand years is a long time for a piece of parchment (animal skin) or papyrus (made from plants) to survive.  Scientists attribute the miraculous preservation to the dry conditions in the caves.  After all, you need moisture for microbe growth and decomposition.

Using radiocarbon testing, which takes advantage of the fact that all living things incorporate Carbon 14 when they are alive, scientists were able to determine that the scrolls dated from the centuries between 250 BCE and 68 CE. One of the first things I noticed in the exhibit was the use of the term BCE (before common era) and CE (common era), which correspond to B.C. and A.D., but are terms used by scientists.

On the scrolls were mostly words of Hebrew scripture, law and even poetry.  Not all of the writing on the scrolls is religious, but the scrolls we viewed were copied from scripts  that would one day appear in the Hebrew Bible and included an Apocryphal Psalm, attributed to King Solomon and to David.  One scroll we saw was a passage from Genesis and all of the scrolls were copied down before the Hebrew Bible had been set in stone.

What fascinated me most about the exhibit was that the scrolls were copied down during such a tumultuous, pivotal time in the heart of a culture experiencing an uprising of the common people and the birth of Christianity.   Archeaologists believe that even as scribes copied the some of the sacred texts onto the scrolls, Jesus was walking through the Holy Land with his disciples.  Rome was gaining power in the region, and the Pharisees, representing the common people of Judea, were beginning to rise up against the Priests, or Sadducees, who tended to come from aristocratic families.  The Pharisees believed in maintaining an oral tradition so that common people, many of whom could not read, had access to “God’s Word”, while the Sadducees believed in a written tradition, which they interpreted very strictly.

Archeologists and Biblical scholars tell us that Jesus was crucified and Christianity was born as modern Judaism was being shaped, the Judeans rose up against the Romans, and the Temple fell, for the second time, in 70 CE, shattering a way of life for many.  Scholars don’t know for sure who hid the scrolls in the caves, or why.  It’s a mystery, but there the ancient manuscripts sat, right before my twentieth century eyes, words marching across the page.  They stared at me from the Minnesota Science Museum, a world away from where they were penned, a testament to a people who would not be forgotten and a time that changed the world.

Having grown up in the Flint Hills and tall grass prairie of Kansas, I was in awe when when we moved to Minnesota, with its 10,000 (or 11,842) lakes dotting the landscape.  The fact that I now have a lake within walking distance of my house boggles my mind.  It’s like a dream to live in a state where you don’t have to be a millionaire to own, or spend the weekend, at a cabin by the water.

I don’t think Minnesotans realize how lucky they are.  We take our lakes, and rivers and streams, for granted.  Sadly, instead of being stewards of our precious waterways, many property owners build structures that harm our lakes, allowing chemicals and fertilizer to wash into the pristine water every time it rains, interfering with the natural wildlife and vegetation.  Not only that, people refuse to replace old septic systems which often cause the lakes where our children swim to be contaminated with human waste. Somehow, we expect our lakes to remain clean and healthy, existing purely for our weekend fun.

Recently, we had a chance to make people take more responsibility for keeping our lakes healthy, so it was depressing to read in last week’s Star Tribune that our governor has once again refused to take measures to care for our local treasures.   “It’s like a parting shot out to Minnesota — thumbing his nose at clean water after all these years, which is a dirty legacy to leave,” said Sen. Ellen Anderson, DFL-St. Paul and chair of the Senate environment, energy and natural resources budget committee.   In fact, our governor is taking care of his own political aspirations and his friends with environmentally-unfriendly lakeside mansions, while pretending to represent the average Minnesotan.

In the book “The Lorax”, by Dr. Seuss, the Lorax speaks for the trees.  Who will speak for our lakes, so that we can continue to enjoy them?  Who will speak for the natural resources you enjoy with your family?  It’s something to keep in mind come November.

For the next week or so, I’ve decided to blog about water.  National Geographic did an amazing job of writing about water and our world in April, and I’m going to participate in P&G’s Give Health “Clean Water Bloggivation”, not to win the trip to Africa, but because they’ll donate clean drinking water to people who need it, in return for participation in the program.  I’ll also blog about how you can make your own lake-front more environmentally friendly by planting a strip of native plants and grasses beside the water.

After spending a weekend relaxing at my parents’ cabin, watching loons, eagles and osprey fishing in the lake, we headed north to Ely and got close up and personal with some much larger Minnesota predators at the North American Bear Center and the International Wolf Center.  Our French visitors were especially excited to experience our wildlife, since bears and wolves have been completely eradicated from their own country.  They informed us that there was only one bear and a few re-introduced wolves left in France.  Fortunately for us, the United States’ depleted wolf and bear populations are coming back thanks to the efforts of organizations like the bear and wolf centers.

At the Bear Center, we watched black bears Ted, Honey and Lucky snack and play from a balcony just above their habitat.  We learned that black bears are much less aggressive than grizzly bears and can usually be scared away from campsites by yelling, clapping, and throwing things at them.  They are also very unlikely to attack people in defense of cubs, which is a grizzly bear trait.  The bears were playful and the 2-year old cub Lucky was especially fun to watch! You can watch these amazing animals live via the “bear cam” on their website at www.bear.org.

Across town, which isn’t very big and is filled with enough canoes and Duluth packs for an army, you’ll find the International Wolf Center.  This organization, whose mission is to advance the survival of wolf populations by teaching about wolves, their relationship to wildlands and the human role in their future, has put together an extensive collection of information about wolves in myth and reality (including lots of cool werewolf legend stuff for “Twilight” fans.) Best of all, the facility houses a pack of four wolves living in a viewable habitat behind the facility.

The pack changes over the years, as new wolves are introduced and the pack dynamics change.  Two arctic subspecies of the gray wolf, Malik and Shadow, born in 2000, were recently put into “retirement” when they got older and the younger wolves got too aggressive with them. Currently, the pack consists of Grizzer and Maya-two great plains subspecies born May 5, 2004 and Aidan and Denali, two northwestern subspecies, born on April 27, 2008.  The wolves weren’t too active when we were there, but at one point, two of them came close to be scratched by some wolf center workers and another took a nap right in front of the viewing window.

The wolves looked like leggy huskies close up and we learned that they have  bigger feet (for chasing prey in the snow) and much stronger jaws than domesticated dogs.  We also learned that their bodies are made to survive nearly two weeks without food, since they only bring down their prey thirty percent of the time.  The wolves at the center are only fed once a week, but you can see them eat if you’re there on the right day.  They eat everything except the stomach of their prey, since the stomach contains plants, which they can’t digest.

You can go to www.wolf.org to read more about wolves and watch their wolf pack live on webcams!

We finished the road trip by weaving our way through tall pines and past hidden lakes to the majestic shores of Lake Superior, where we took the scenic highway down the North Shore.  Stopping to play on the rocks and hike down to the lake at Gooseberry Falls State Park was a highlight of the trip, even as rain started to fall.  My husband looked like a kid again as he waded smiling into the frigid water of Lake Superior and stomped around in the waves.  I felt thankful to live in Minnesota and for all the efforts people have made to preserve our wilderness and nurture our native species.

We spent last week in Iowa at a family reunion at lake Okoboji, a deep, clear, gorgeous lake near the Minnesota border.  My great grandparents had a cottage there, and every year my mom’s side of the family returns to spend a week swimming, fishing, going to the lakeside amusement park and just hanging out.

Gull Point is a pretty piece of land with a sandy beach and sandbar that juts out into the lake and is one of our favorite destinations. Each year we spend an afternoon or two there, swimming, skipping rocks and digging our toes into the sand.  We didn’t see many gulls this year, but there was a pretty white pelican hanging out nearby.  Little did I know that water birds carry a tiny parasite that infects snails in the water.  The parasite’s larvae are then released and swim around looking for a suitable mammalian host to burrow into and continue their life cycle.

Ignorant of the tiny bugs digging into our skin, we frolicked in the water for hours.

Humans are not a good host for these parasites and they soon die, leaving their buggy corpses under our skin.  Some people don’t have much of a reaction, but others have immunes systems that kick into high gear, rejecting the dead parasites with an inflammatory response in the the form of big, itchy, awful bumps.

My son is definitely allergic.  The CDC website has more information on Swimmer’s Itch, or Cercarial Dermatitis, which can also be found in many Minnesota lakes.  Generally, it doesn’t need much treatment except Hydrocortisone cream or Calamine lotion.  My daughter and I have a few itchy bumps, but nothing major.  My son, on the other hand is on oral prednisone too calm his allergic reaction.  Needless to say, it has been a long, long week.

According to the University of Minnesota’s Extension Service, you can do the following things to reduce your chances of getting severe swimmer’s itch:

• Dry off as soon as you leave the water. Rub skin briskly to remove water drops before they evaporate. Be sure to dry underneath waistbands and around leg openings. Encourage children to dry off thoroughly each time they leave the water.
• Shower with soap and fresh water or change into dry clothes as soon as possible.
• Don’t wade or play in shallow water. Swimming from a raft or pontoon minimizes your exposure.
• Don’t feed geese and ducks near your beach. Waterfowl are an important adult host for the parasites.

In today’s paper, I was disgusted to read that two school-age children, a toddler and a 70-year old man were victims of an E.coli outbreak this week caused by raw milk from a Minnesota dairy.  The toddler is currently hospitalized with a serious condition related to the infection (hemolytic uremic syndrome) which can cause kidney failure and death.  These are unnecessary illnesses and people are putting themselves and their children at risk by drinking raw milk.

Pasteurization is the process of heating up food to kill any bacteria it might contain.  Louis Pasteur first tested the process in 1864 and it is perfectly safe.  However, some people who drink raw milk feel that beneficial proteins and bacteria are destroyed during the heating process.

According to the Health Department, several dozen people are sickened by raw milk every year in Minnesota.  Unpasteurized milk can contain the live pathogens, or bad bacteria,  E. coli, Salmonella and Campylobacter.  Most people are careful handling and cooking  meat to avoid the very same pathogens.  Why they wouldn’t mind drinking them is a mystery to me.

Beneficial, or “good” bacteria can be found in most yogurt and many companies now add beneficial bacteria to other dairy items, including pasteurized milk.  I suspect that many of milk’s other beneficial heat-sensitive proteins can be found in other, safe foods as well.  Even raw milk cheese made correctly is safer than raw milk, because it contains other microbes that inhibit the growth of pathogens.

Maybe people don’t realize it, but giving their child a glass of raw milk is as risky as feeding them a raw hamburger.  I’m glad to hear the state is cracking down.

Last  night, as 39 of my fellow Minnesota bloggers and I gathered to pack food for “Feed My Starving Children” , we were asked the question, “what is the difference between hungry and starving?”  The dictionary defines hunger as experiencing a desire or need for food, while starving is defined as: to suffer or die from extreme or prolonged lack of food.  In fact, when you are starving, your body actually begins metabolizing, or eating itself.  If you don’t get food, you will die.  The only way to reverse the process is to give a starving body nutrients with which to rebuild itself.   

We mixed together soybeans, chicken-flavored vitamins, vegetables and rice in small plastic bags to be sent to another country, possibly Haiti, to feed starving people.  People like us.  Children like our children.  Together, in less than an hour, our group, along with three or four others, packed 13,824 meals:  enough food to feed 38 people for a year.  It is astonishing that so little effort can change, and possibly even save, so many lives.  To learn more about Feed My Starving Children and how you can help, visit their website.
