Sassy Advice - Say it, Or Write it, Or frickin' pull it out by hand. Just don't Spray it.

As far as Day Jobs go, mine is pretty alright.

I work in a beautiful provincial park. I feel indebted to the foresight of environmentalists every time I drive to work here: as much as it can be while still being a tourist destination, this place is protected.

Unless there are weeds.

You see, the activities of us fun-loving humans have brought a few invasive species into this delicate mountain ecosystem. Some of them are classified as 'noxious weeds' throughout the province and are being aggressively sprayed with poisons recently shown in peer reviewed scientific literature to cause birth defects and cancers in mammals.

Like, you know, us humans.

Now, we thoughtful and good-looking humans who know a bit about ecosystems know that healthy ecosystems are far less susceptible to the advances of this invasive plants. Unfortunately, my particular place of work does not qualify as a healthy ecosystem. The accidental planting of weed-seed-contaminated, suited-to-warmer-climates grass as a landscape staple, and damage to the soil from ongoing construction have provided the perfect place for invasive dandelion and thistle.

So my boss has decided to spray herbicides. Here. In a supposedly protected provincial park.

The amount of thistle and dandelion is very minimal. It could be pulled by hand in a couple of days. Sure, it will likely come back. But guess what? It will come back if you spray it, too.

I've spoken with my boss about this twice now with no luck, and am waiting for a call back now that he has decided to go ahead in spite of my concerns... this Wednesday.

What are my concerns?

I'm glad you asked!

1. Herbicides hurt humans.

Most herbicides use glyphosate as their active ingredient. Glyphosate  causes birth defects in humans. It is associated with long term health problems including cancer, especially cancer in children.

Herbicides are also known to cause respiratory distress. Many of the people who come to my place of work have respiratory problems to begin with. If we claim to be an accessible facility to people with special needs, we have to include respiratory needs in that claim.

2. Herbicides hurt the environment.

Glyphosate also “causes birth defects in the embryos of laboratory animals” according to Lucia Graves of the Huffington Post. Even low doses are shown to cause abnormalities in rabbits, including dilation of the heart.

It promotes soil pathogens and inhibits plants’ immune systems.

We are located in an extremely important watershed. Scientific American reports that glyphosate leeches into water.

Perhaps glyphosate is not the chemical that will be used here. Perhaps it is aminocyclopyrachlore, another common herbicide claimed to be more environmentally friendly, which causes mass tree deaths, especially in conifers.

Perhaps it’s the popular atrazine, which is still present in ground water 15 years after its use, causes breast and prostate cancer, and reproductive defects in birds, fish and frogs.

Either way, I cannot fathom how something so harmful to flora and fauna can legally be applied in a supposedly protected area.

On top of all of that, my partner and I are going to be starting a family soon. How could I conscionably expose myself to chemicals that could cause birth defects and / or cancers in my babies? My workplace will be sprayed on Wednesday. I'm supposed to work on Friday.


The mostly-wild places of Kananaskis Country are under enough pressure from tourists, logging and damns without having poisons sprayed on them.

Those Evil Red Ants

Fire Ants. Carpenter Ants. Biting Ants.

Red Ants.


Just thinking about them made me, well, antsy.

Especially because there is a huge colony of them in my backyard. I was concerned for my pets, who are quite oblivious to these fellows, and of course, for my garden.

But now I have seen the light!

The ants in my yard are western thatching ants. It turns out that these bad boys eat herbivorous insects, especially aphids, which means that they can act as a police force protecting nearby plants that might otherwise fall prey to excess herbivory. That they are already established is a bonus: by including them in my plans for the garden, with some knowledge of their habits and behavior, I can do what permaculturists do best:

Turn unwanted ants into another ally in the garden.

Huzzah!

My garden design is evolving and becoming more detailed every day. With this new information, I have one more concrete goal to help the design gel: I want to surround these ants with plants that need protection from pests. I also want to ensure that they have adequate water supply, so I will elongate a burm that I've designed into the garden, bringing it right past them. I will also cut off the possibility of negative ant-pet interaction by fencing off the donut of delight that will be: THE ANT GARDEN.

There will be an offering of raspberry bushes and / or milk thistle very close to the colony (as close as I can get without becoming terrified of bites and running away) for them to 'ranch' their aphids. These bushes will likely suffer as the aphids are encouraged by the ants to eat them, become plump with nectar, and then become food themselves. Around those I'll put plants that are less attractive for aphid ranches, but may become prey to slugs or beetles. My theory is that the ants will find those pests during their rounds, and hunt them for food, thus protecting the plants in the long-run. Finally, I'll put a fence around the whole donut to keep the dogs out!

I'll let you know how it goes.

It is supposed to be sunny for a few days after nearly a week of late-season snow. Can't get to get outside and start building!
