Have you ever been outside, maybe working in the garden, soaking up rays by the pool, or snoozing in the hammock, when suddenly a flying, sparkly green centurion with pointy black spear charges up, out of nowhere, dangerously close to your face?

This thing, whatever it is, seems simply to pop into existence with no more than a strange humming buzz, challenging your presence for a moment, and then popping back into the ether with a nigh-unperceivable tirade of twittering squeaks. You may be tempted to swat at it, thinking it is some monstrously mutated mosquito.

But then your stupor breaks and you realize the truth: You have just had a close encounter of the hummingbird kind.

These winged warriors are fantastic wonders of nature. Hummingbirds know not of fear and will faceoff with just about anything, curmudgeons that they are. They can perform feats of motion that almost defy the laws of physics, that seem to create G-forces strong enough to shatter the strongest material. And yet there they are, again and again, twirling and twittering and teleporting through the air nearly faster than the eye can see.

(And, if humans could understand them, they are probably cussing each other, us, and every other thing that is not sweet nectar. For Sheri Williamson of the Southeastern Arizona Bird Observatory has to be right in thinking that “the hummingbird vocabulary is a hundred percent swear words”!1)

According to No Child Left Inside, “A study found that young people could identify 1000 corporate logos but fewer that 10 plants or animals native to their backyards.”

Editor’s note: Part 3 of the “Human Interaction with Nature” series focuses on an endangered plant species: echinacea. This post, and the accompanying podcast, were created by Bobby Grace, and originally published on Friday, May 19th, 2008.

I spoke with KU professor, ethnobotanist, and Medicinal Wild Plants of the Prairie author Kelly Kindscher about the sustainability of Echinacea.

Echinacea is a species native to Kansas that is used as a general cure all and as protection against the common cold. In the United States, herbal medicine has gone by the wayside and today the main importer of Echinacea is Europe. The demand has leveled off, but there are still people harvesting the species.

Editor’s note: Last week, we published a piece by our editorial intern Oscar Cardenas on the endangered status of many herbs used in alternative health practices. Today, we’re pleased to give you Oscar’s second piece on the subject, which focuses on the popular herb Echinacea.

Imagine an organism, native to the American prairie, whose value to people prompted wholesale hunting to fill the demands of a niche market. In the period of roughly a decade and a half, consumers managed to rediscover and exploit natural reserves of this species which had originally been utilized by Native Americans in the eastern United States. The organism, echinacea (not the American bison), consists of 9 species of plants, some of which are recognized as endangered by federal and state authorities.

What Is Echinacea and How Does it Work?

The blanket term echinacea usually refers to three species of this plant: Echinacea angustifolia, Echinacea purpurea, and Echinacea pallida. All three varieties are native to North America and are often packed into individual or homogenized mixtures that are marketed as immunity boosters and touted to either prevent colds or lessen their impact/duration. Echinacea can be used preventatively or post-exposure to shorten the duration of colds when the rhinovirus (the cause of the all-too-common cold) has invaded and incubated, causing symptoms (the sniffles). Doses are delivered orally and come in the form of tinctures, pills, or drinks with intake instructions specific to the product listed within the packaging.

Editor’s note: While many will argue that there’s no such thing as an “eco-friendly lawn” (with justification), the grass covered yard is still a staple of most homes. Today, our friends at Low Impact Living have some tips for “greening” your lawn… while keeping it green. This post was originally published on May 7, 2008.

Summer is just around the corner, and this is the time of year when we really ramp up our lawn activities– watering, fertilizing, mowing, etc. And all of these can have major negative environmental consequences. Did you know that over 50 million Americans mow their lawns each weekend, and contribute as much as 5% of the country’s air pollution? And it’s staggering to realize that the average American grassy lawn can use over 20,000 gallons of water each summer! So, a major part of any green home strategy should be to embrace eco-friendly lawn and garden care.

Here are 12 ways you can make sure you have an eco-friendly lawn this summer

1. Collect rain water and use it for your plants. Getting a rain barrel or two for your yard is a simple way to collect and reuse Mother Nature’s water. Just put it under your gutter’s down spout and you’ll be amazed how fast it fills up. Click here for rain barrels.

2. Make sure you’re not over-watering. Most of us over-water our lawns. Do you have moss growing on your driveway or sidewalk or in your garden? That’s a sign you’re watering too much. Do you have pools of standing water anywhere? Another sign. You can buy a very inexpensive lawn moisture meter that will tell you if you’re over-watering. You might also consider getting an intelligent irrigation control system that attunes your watering to the weather and your lawn’s needs.

Every time I go into a craft store, I visibly cringe while walking past the “floral” department. Some marketing genius decided to refer to them all as “silk” flowers, rather than what they really are: horribly fake plastic imitations of plants. Either way, I’m on a mission to dissociate that muck from mainstream crafting once and for all.

That is, until it becomes “the thing” to find their relics in thrift stores, and use them to make something really cool we haven’t even thought of yet. This isn’t to say that high quality, environmentally friendly silk and natural varieties don’t exist, but generally you will only be able to find them through a florist.

So, how do we fight our way out of the indoor polyester jungle? We should join forces to form a Fake Plastic Flower Death Squad. Here is our plan of action:

New research from the National Science Foundation suggests a warming Earth could mean a significant increase in voracious, plant-eating insects.

Scientists studying the Paleocene-Eocene Thermal Maximum (PETM), a period about 55 million years ago when global carbon dioxide levels spiked rapidly, found that plant fossils from that time show noticeably more insect damage than plants from before or after the PETM. They [...]

Ever wonder what these plants are saying to one another? Researchers in the Netherlands say there’s an early-warning network in place. Is it only clover, no, many herbal plants have been studied.

And what about talking to your plants,does that work? And can one plant feel inferior to another?

If you have a garden, you know the climate is warming. In temperate zones, the last frost in spring comes earlier, and the first frost in fall comes later. The longer growing season may allow you to grow vegetables you never could grow before. But you also may have noticed your weeds are more aggressive, insect pests are [...]

Your garden doesn't have to suffer just because of water restrictions or drought problems. Collecting water that would otherwise go down the drain will make you and your plants happy.
