In what ways is buckthorn harmful?

Sun, 2015-04-12 16:54
I spent 10-15 hours a week in various locations of still-wooded Chicago (and now nearby Lincolnwood) cutting down buckthorn. Some people have taken me to task for it ("Just let it be, let nature take it's course, etc.). So I thought I would share this excellent, concise sum up of the damage that can be wrought by buckthorn.
And if anyone lives on the north side of Chicago and would like to help out, there is both "heavy" work (cutting large trees and dragging them around) and now lots of "light" work (clipping the new growth from the stumps from last year's cutting - I don't use poison). 
It's great exercise and without a doubt you will be helping rescue native trees and ensure that the next generation of those trees will survive and thrive!
From The Landscape Guys
Buckthorn should be on America's "Most Wanted" list, with its picture hanging up in every US Post Office! Here are a few of the dangers of Buckthorn:
a) Buckthorn squeezes out native plants for nutrients, sunlight, and moisture. It literally chokes out surrounding healthy trees and makes it impossible for any new growth to take root under its cancerous canopy of dense vegetation.
b) Buckthorn degrades wildlife habitats and alters the natural food chain in and growth of an otherwise healthy forest. It disrupts the whole natural balance of the ecosystem.
c) Buckthorn can host pests like Crown Rust Fungus and Soybean Aphids. Crown Rust can devastate oat crops and a wide variety of other grasses. Soybean Aphids can have a devastating effect on the yield of soybean crops. Without buckthorn as host, these pests couldn't survive to blight crops.
d) Buckthorn contributes to erosion by overshadowing plants that grow on the forest floor, causing them to die and causing the soil to lose the integrity and structure created by such plants.
e) Buckthorn lacks "natural controls" like insects or diseases that would curb its growth. A Buckthorn-infested forest is too dense to walk through, and the thorns of Common Buckthorn will leave you bloodied.
f) Buckthorn attracts many species of birds (especially robins and cedar waxwings) that eat the berries and spread the seeds through excrement. Not only are the birds attracted to the plentiful berries, but because the buckthorn berries have a diuretic and cathartic effect, the birds pass the seeds very quickly to the surrounding areas of the forest. This makes Buckthorn spread even more widely and rapidly, making it harder for us to control and contain.

Consumer Reports guide on which fruits and veggies to always buy organic

Mon, 2015-04-06 09:32
First, I encourage everyone reading this (and beyond) to subscribe to Consumer Reports and make use of their unbiased, science-based reviews of products and services.

It is the best antidote to advertising you will ever find.

In their May 2015 issue, they analyze the "perils of pesticides" and offer a guide to fruits and vegetables. When you should buy organic? When might conventional be OK for you?

[or, as CR puts it, "Though we believe that organic is always the best choice because it promotes sustainable agriculture, getting plenty of fruits and vegetables - even if you can't obtain organic - takes precedence when it comes to your health.]

Here are the most important findings:

ALWAYS BUY ORGANIC

CR found that for these fruits and vegetables, you should always buy organic - the pesticide risk in conventional is too high.

Fruit

Peaches
Tangerines
Nectarines
Strawberries
Cranberries

Vegetables

Green Beans
Sweet Bell Peppers
Hot Peppers
Sweet Potatoes
Carrors

Who enjoys the feather display of a male peacock?

Tue, 2015-02-24 08:25


Who appreciates the display of feathers by a male peacock?
Female peacocks seem to get a kick out of them. They seem to play a role in mating rituals.
Who else? Why, humans, of course!
We know that humans greatly appreciate those displays, because of the aaahing and ooohing that goes on when we see them. We like those colors. We like the irridescence. We like the shapes and patterns.
If one were to speculate on why a female peacock gets all worked up about a particular male's feather display, we would inevitably hear about instinctual responses, hard-wiring, genetic determinism, and so on.
And if one were to speculate on why a human goes into raptures, we would then experience a major shift in explanation. 
Time to talk about anything but a physiological, hard-wired sort of response.
No, for humans, the attraction has to do with our big brains, our ability to create and appreciate "art". And that is most definitely not something other animals do, right?
Oh, sure, right. Like these instinctive, hard-wired bowerbird mating nests:

That clearly has nothing to do with an aesthetic sense or "art". Just instinct.
Why? Because we humans say so. We just assert this "fact."
Most convenient, eh?
