When rain comes in abundance, the world turns green.
From the top of Sawtell Mountain, Island Park looked like a shimmering emerald in the late afternoon light. From the dark greens of the conifer forest to the lighter shades of aspens and meadows, a very wet and cool spring had created a green-hued world that was intense and lovely, reminiscent of a rainforest.
The exceptional green colors of spring are not a coincidence. Rain plays an integral part in that greening beyond just bringing moisture. What rain adds to the nutrient cycle is equally important.
Plants are constantly developing new roots as fine, hair-like roots die. It wouldn’t take long for soil systems to become choked with dead roots—which consist largely of carbon and nitrogen—were it not for one thing. Fortunately, soil is also full of microbes that carry out most of the heavy lifting that creates conditions for plants to thrive. These microbes digest the fine roots, using the carbon elements and some of the nitrogen for their own needs, and releasing nitrogen as a by-product. As any gardener knows, nitrogen is one of the main nutrients required for healthy plants.
Rain, or irrigation, provides the moisture to allow soil microbes to increase their activity. As the soil becomes wet, they boost their composting action and more nitrogen is released as waste that the plants readily absorb.
There is one other factor involved with rain that irrigation cannot mimic. Our atmosphere is about 78 percent nitrogen gas and also contains minute particles of nitrates and ammonia. When it rains, these chemicals are washed from the air and added to the soil, boosting plant activity.
This atmospheric soil addition can be a big deal, depending on where in the country you live. Some places receive much more than others. There is even a national program, National Atmospheric Deposition Program, that tracks all deposits, not just nitrogen, from the atmosphere.
Even lightning associated with thunderstorms plays a role in this nitrogen cycling. The energy released by a lightning bolt can oxidize nitrogen gas, freeing up more nitrates to be washed down onto plants with the accompanying rain.
Total soil moisture also plays a role. A brief shower after a prolonged dry spell will not activate soil microbes like a long storm would. In addition, if the entire soil column is moist, then all of the root systems of plants can be available to absorb nutrients released by microbes or added through “sky washing”.
The bottom line is that the moister the soil (there are limits), the more nutrients will become available to plants. Well-fed plants are more active, thus, greener.
Finally, as water becomes less available, leaves begin to sag and, if drought conditions continue, will even turn brown. On the other hand, lots of moisture loads leaves up, much like filling a water balloon, to their maximum size. Leaves and stems full of water are at their showiest.
Of course, there can be too much of a good thing. If soils are saturated and it continues to rain, highly mobile nitrogen molecules can be carried right past the root zone and once again become unavailable to the plants. Worse, nitrates and other chemicals can be washed into streams, rivers and lakes creating an overabundance of aquatic plants and algae.
Rain, incessant rain, had me cussing for a long while this year. However, if the fabulous green forests and meadows are the result, I guess I really didn’t mind so much.
Help Idaho Wildlife
When we traveled across the state in October 2017, most of the vehicles we saw using the wildlife management areas did not have wildlife plates. Buying wildlife plates is a great way for non-hunters and hunters alike to support wildlife-based recreation like birding.
C'mon folks, let's help Idaho's wildlife by proudly buying and displaying a wildlife license plate on each of our vehicles!
See below for information on Idaho plates. Most states have wildlife plates so if you live outside Idaho, check with your state's wildlife department or vehicle licensing division for availability of state wildlife plates where you live.
Wildlife License Plates
Idaho Wildlife license plates provide essential funding that benefits the great diversity of native plants and wildlife that are not hunted, fished or trapped—over 10,000 species or 98% of Idaho’s species diversity. Game species that share the same habitats (such as elk, deer, antelope, sage-grouse, salmon, trout) also benefit from these specialty plates.
No state tax dollars are provided for wildlife diversity, conservation education and recreation programs. Neither are any revenues from the sale of hunting or fishing licenses spent on nongame species. Instead, these species depend on direct donations, federal grants, fundraising initiatives—and the Idaho Wildlife license plates.
Both my vehicles have Bluebird Plates. I prefer the bluebird because the nongame program gets 70 percent of the money from bluebird plates, but only 60 percent of the money from elk and trout plates - 10 percent of the money from elk plates supports wildlife disease monitoring and testing programs (to benefit the livestock industry) and 10 percent from cutthroat plates supports non-motorized boat access.
Incidentally, in 2014, the Idaho Legislature denied the Department of Fish and Game the ability to add new plates or even to change the name of the elk and cutthroat plates (very specific) to wildlife and fish plates, a move that would have allowed for changing images occasionally and generating more revenue. It would seem that they believe that we Idahoans don't want a well funded wildlife program. Go figure.
"WOW. What a phenomenal piece you wrote. You are amazing." Jennifer Jackson
That is embarrassing but actually a fairly typical response to my nature essays. Since The Best of Nature is created from the very best of 16 years of these nature essays published weekly in the Idaho Falls Post Register (online readership 70,000), it is a fine read. It covers a wide variety of topics including humorous glimpses of nature, philosophy, natural history, and conservation. Readers praise the style, breadth of subject matter and my ability to communicate complex and emotional topics in a relaxed and understandable manner.
Everyone can find something to love in this book. From teenagers to octogenarians, from the coffee shop to the school room, these nature essays are widely read and enjoyed.
Some of the essays here are my personal favorites, others seemed to strike a chord with readers. Most have an important message or lesson that will resonate with you. They are written with a goal to simultaneously entertain and educate about the wonderful workings of nature. Some will make you laugh out loud and others will bring a tear to the eye and warm your heart.
"You hit a home run with your article on, Big Questions in Nature. It should be required reading for everyone who has lost touch with nature...great job!" Joe Chapman
"We enjoyed your column, Bloom Where Planted. Some of the best writing yet. The Post Register is fortunate to have your weekly columns." Lou Griffin.
