Dragonflies

DragonflyImage via Wikipedia

If you're lucky, dragonflies will join the birds and butterflies in your Backyard Wildlife HabitatTM site this summer. You will enjoy their presence -- especially during cookouts and other outdoor activities -- because they eat those pesky mosquitoes and flies. Dragonflies are attracted to water. Therefore, if you have a birdbath, water garden or pond, you may also have dragonflies.

Dragonflies have roamed the earth for over 300 million years. They have inspired both awe and fear in us with their fierce beauty and fascinating lifecycle. Born underwater to emerge from a life in mud and sand, a dragonfly nymph transforms into "a living flash of light," as Lord Tennyson once described them. The 2,500 different species of dragonflies come in many colors -- blue, green, purple and bronze. Their aerial acrobatics are made possible by powerful wings that generate small tornadoes of air that keep the dragonfly moving at speeds of up to 60 miles an hour.

Like many birds and some butterflies, dragonflies migrate. But unlike other migratory creatures, the phenomenon of dragonfly migration is very much shrouded in mystery. It is the combined flight patterns of millions of dragonflies that have become a mystery to modern researchers. You may have seen a group of dragonflies fly by and wondered with curiosity, "Where are they going?" As yet this remains unanswered, as do many questions. It is not even certain why dragonflies migrate. One day these mysteries may be solved. In the meantime, all we can do is watch them in awe, admire their beauty and thank them for being so helpful around the yard!

Soybean Pollination Experiment

This experiment was carried out to evaluate the effect of the honeybee pollination in the production and quality of soybean seeds (Glycine max L. Merril). Seed production was higher (P=0.0001) in covered areas with honeybee colonies (50.64%) and uncovered areas (57.73%) than in covered areas without honeybee colonies. It could be concluded that honeybees were responsible for 95.5% of the pollination accomplished by insects. The pod number in covered treatment with honeybees was 61.38% higher (P=0.0002) than in the covered treatment without honeybees. The average weight of 100 seeds was larger (P=0.0001) in the area covered without honeybees, and reached 17.8 g. The medium content of crude protein in grains was 36.7% and the average oil content was 20.2%. The germination test did not show differences (P>0.05) among the seeds in different treatments. It was concluded that the honeybee pollination in the soybean increased the seeds production.

4th Annual National Pollinator Week, June 21-27

Taken from The Great Sunflower Project
www.greatsunflower.org

This week is dedicated to raising awareness of the value of those hard-working pollinators that account for every third bite of food we eat. Governors of more that 30 states have designated the last week in June as “National Pollinator Week.”
And it is being celebrated in the U.S., Canada, Mexico and around the globe as more and more people are realizing the value of pollinators as part of our food web.
“A World of Pollinators” is the theme for 2010 National Pollinator Week.

What can we do for pollinators? Start with one observation. And from there a whole new world can open up. Each observation you record and report will be part of a growing body of data that we can use to measure pollinator service around the country. But observation is only the start. We can take action, too!

Add a yard to your yard
In a recent study conducted by the National Academy of Sciences-National Research Council, loss of habitat was identified as a major cause of the decline in the number and types of bees nationwide. By planting for pollinators, we can rebuild pollinator habitat and make a significant, positive impact on the survival rates for honey bees and other pollinators. Whether urban, suburban or rural, pollinators rely on “key species” to obtain the vital nectar, pollen, and nesting resources they need to keep thriving. These key plants are critical for survival and can be incorporated easily into your garden. If everyone added another square yard of habitat species to their gardens, just think of all the additional resources that would be available for bees to get what they need to give back what we depend on.
So if you have the room, take action! Add a pollinator yard to your yard and let us know how it goes for you.
Here’s how it works in six easy steps:
1. Select a spot in your yard that gets sun and would look great planted out with more flowering plants.
2. Measure out three feet by three feet and mark it off. You may have to remove turf, large rocks, or lawn furniture.
3. Condition the soil, by adding organic topsoil or compost and working it in.
4. Select plants that offer a variety of pollen and nectar through out as much of the year as your climate supports flowering plants. Check with your local nursery, master gardener group or botanical garden for ideas. Native plants are always a good choice.
5. Plant it out and enjoy the benefits of providing critical resources for pollinators in your garden.
6. And, make sure to take “before and after” pics of your garden- you can post them on flickr We will be awarding a jar of delicious honey from Gretchen’s hives to the lucky photo winner.

We invite you to celebrate National Pollinator Week with us. Take action and add a yard to your yard. We also suggest that you check out www.pollinator.org/TAP.htm for a list of ideas throughout the year. This new program sponsored by the Pollinator Network highlights specific actions that school groups, farmers, gardeners, and others can take to “Take Action for Pollinators.” You can purchase or download this beautifully done poster there, too. Happy National Pollinator Week!

Benefits of Planting Live Wildflower & Grass Plant Plugs

The plugs in the 84 Nova trays measure 1 1/8 inch diameter by 2 7/8 inches deep and taper like a cone with a bottom drain opening. The interior ridged design of the plug directs root growth downward & avoids the wrap around growth allowed by smooth sided plugs. As the roots develop & escape through the drain opening of the plug the atmosphere will burn off the protruding root material, in effect pruning them to encourage constant development of fresh root growth. When the plugs are placed into the ground, the roots are ready to rapidly establish themselves down into the soil. It has been our experience with planting both 3” square pots & the 84 Nova plugs that the plugs will compete with & sometimes surpass the growth of the larger potted plants in the first growing season. Some species planted as plugs will flower & set seed in the first year-we had Sawtooth sunflowers that were planted in June reach nearly 8’ & flower in the same season. The size of these 84 Nova plugs makes them easy to handle in planting & transporting. Native Plant Plug

How Plants Protect Us From Disease

ScienceDaily (2009-04-27) -- Everyday foods, beverages, and spices contain healthful compounds that help us fight harmful inflammation. And, in doing that, these phytochemicals—the resveratrol in red wine or the catechins in green, white and black teas, for instance—may also reduce our risk of diseases associated with chronic inflammation, including cancer and diabetes.

Nature Deficit Disorder ... Not Here!


DO YOU HAVE NATURE DEFICIT DISORDER

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 and me?
