Spiny Amaranth


I believe I have made a new discovery with my plant identifications. I am going to contact a local expert for verification, but in the meantime I am tentatively identifying a previously posted plant as spiny amaranth.
Here's a photo of my plant. One key characteristic that I am not really sure of is the plant's spiny texture... but I will confirm that tomorrow. It sure looks like a scary plant to me, and I used to regard it as evil. Alas, it may be quite valuable to us, as amaranth is a very nutritious food source.

I'm not going to go on a research tangent, as this was an accidental discovery during another research project. However, survivallady.com has a nice little blurb about amaranth in her post "Using Wild Plants As Food."

More on Tallow

An excellent point was brought up by Thais over at Port Hudson Organics, that the bees love the Tallows!
Earlier in the spring when the weather was a bit cooler, Callum and I were walking around the field and made our way over to one of the tallow tree circles (I'll tell you about these in just a minute). The trees had just begun blossoming and as we neared the trees we heard a constant electric hum. Upon closer inspection I saw that the trees were buzzing with wild honeybees! This is quite a reassuring sound amid reports of declining honeybee populations.
The American honeybee is a welcome presence in any garden and the long, golden, chain-like flowers of the Tallow are a honeybee favorite.

Any Tallow management project would have to take into account the benefit of these trees for wildlife. Not only do the bees love'em, but the birds do too. Of course, the birds end up being part of the problem when they spread the seeds to surrounding natural areas.
It is most likely that our project on the farm would be a management project rather than eradication. The Tallow tree problem in some southern states has gotten to the point where landowners are advised by the state to remove these trees from their property entirely. However, as young and energetic as I am, I can't imagine the cost and energy required to rid the property of these trees (nor do I want to think about all the herbicide that would have to be used if we found ourselves forced to take that route).


Here is an idea of what we are dealing with. The picture above is the property immediately in front of our house. Every tree you see, besides the lonely maple sapling up in front, is a Tallow. While the cows were here, they grew up along the fence lines. The "Tallow Tree Circles" are 3 big circles next to our house where the trees were cut down and piled up about 20-30 years ago. The area was not mowable because of the huge debris pile, and the seeds of the "debris" trees were able to germinate and grow undisturbed. In the back of the property where there are still a few old oaks, gum, pine and maple growing, the Tallow is busy taking over the understory and competing with the younger versions of these already established trees.

Ultimately it would be nice just to clear out patches of these trees at a time and establish and nurture the growth of other species that are equally hospitable to the wildlife. It would probably be a good idea to start with the areas where seedlings of other species are already trying to establish themselves. Help those along first, and clear out the Tallow competition. Later, we could move on to the mini Tallow forests themselves.

We are still thinking of ways to approach this issue, and any suggestions or feedback are certainly appreciated!

Tallow Tree Daydreams.


Occasionally I find myself absorbed in daydreams of eradicating the Tallow Tree. I spent some time earlier today wandering around photographing the Tallow for a new web lens I'm creating that focuses on managing Chinese Tallow. Control of this species is critical to preserving the property. Take a look at the link to find out more.
Also, after I wrote the last entry I decided to go out and get a few things done. I made the border for a vegetable bed in the front and moved some gravel from under the trailer to make a path so I don't end up walking through mud while trying to get to the veggie bed. I also repotted some of the young cacti that Ronnie gave me.

I took tons of photos this evening of the various grasses and plants growing out in the field. I will organize it into a photo tour in one of my upcoming entries, so stay tuned!

Philosophy of grasses.


How GREEN!

As I walk through the fields I find myself grabbing the stalks of these plants, tugging at the inflorescence (the flowering part-- I have recently learned courtesy of the University of Florida), and feeling a subconscious satisfaction when my hand is quickly filled with little grass seeds. Then what do I do with these seeds? I toss them aside-- for what do I need this strange plant material?

I had never considered it before, but my subconscious habit to grab the seeds and spread them around is a perfect example of the brilliance of nature's system. Things are meant to work together in this way. As we become more aware of our surroundings, we also become more aware of the impact even our smallest, most insignificant habits have on those surroundings.

As much as we unconsciously aide the spread of certain species, we also unconsciously destroy others (or even the same). It takes much awareness and an extremely open mind to develop an understanding of our true impact on the Earth's systems. Even then, can we really change ourselves all that much? Do our changes truly make a difference, or do they just shift the impact to another area?
This question reminds me of Newton's simple observation: "for every action, there is an equal and opposite reaction." Can we really do "good" without then enabling, somehow and somewhere, something "bad"? Is there really any way that we can assign these values-- "good" and "bad" at all if they both exist simultaneously within the same action?

Okay, I'm not here to delve into moral rhetoric, but I just want to expose a bit of my own belief that there isn't and never will be a "good" way to do things versus a "bad" way. Our actions are all just experiments; conscious experiments; unconscious experiments; observations and explorations. We are just tinkering with our world in the ways in which we were designed. Our world is also tinkering with us.

This thinking isn't an attempt to absolve myself from making choices which I perceive to be the right choices, the compassionate and considerate and generous choices that I really do hope to make. This thinking is only a way to comfort myself when I feel that I havent done enough-- that I haven't made a difference and that what I am doing is worthless or trivial. Nothing is worthless or trivial. Nothing at all.

Enough of that... let's talk about grasses.

I am in the process of learning about grasses and meadow plants. Funny, cuz I never would have imagined myself interested in grasses. Who cares about grass? It's everywhere! Big deal...

I remember in the early days of my plant scholarship (I say that as if I am an advanced botanist, because it makes me feel good) I would browse through the college catalog looking for horticulture courses and I would find all these courses about "turfgrass." The only turf I knew existed on golf courses and I found that stuff repulsive and absurd. I'm somewhat sorry to say that I've changed my opinion. Okay, I still think golf courses are repulsive and absurd, but the little plants that inhabit them are only doing what they have been manipulated into doing-- and they sure do seem to be doing well!

So this entry is my tribute to the grasses short and tall, the creepers and the taprooters and everything in between. Oh I just love grasses!

What got me started on this? Right next to our trailer we have a huge circle of mud from where the septic tank was dropped into the ground. Under the trailer we have pure red clay. When it rains this place is terrible-- mud on everything. It's a little better now that we have built steps off the other side of the porch, but not too pleasant either way.

So I look out into the field with envy. Delicate easter basket grasses, thick weedy grasses, strange plants of all sorts and, of course, the ever-present tallow shoots. I don't care, I just want something to cover up this mud!

I walk down the road and look at my neighbors extensive, manicured lawns. When I say extensive I mean it! These people have taken perhaps 100 acres (together) or more and they have set free these tough, durable little plants which have probably been created in some research lab at a university somewhere (LSU perhaps?). I am shocked, repulsed, and impressed by this! Of course, it's not only my neighbors lawns, but lawns all over the parish, the state, the country. It seems grasses are creeping and crawling slowly to consume to all four corners of the Earth. Some do it with the assistance of chemicals and fertilizers (also created in some lab somewhere), and some do it with the assistance of ignorant homonids.
Either way, it is a full blown invasion.

And I love it. Why do I love it? I love it because it is a perfect example of nature at its finest. Sure, some may say that turf grasses are not natural, especially those that are fully dependent on our obsessive-compulsive nature, but the funny thing is that they are natural. Nature has provided for these dear little plants a species so deeply concerned with their survival that they will do just about anything to promote it. That and a little sunshine is all anyone needs, right?

Let's hear it for the grasses!

Quiet times.

Today has been a slow day. Our neighbor was supposed to come by today to help bushhog but he hasn't gotten around to it. As it is, the grasses and tallow trees are growing up all over the place. Most of the vasey grass has had time to make seed and the seeds are ripe now. I'm not familiar with how that stuff grows out here but the pasture was always short before, because of the cows, so there's a possibility that things will really get crazy now that it has time to grow up and propagate. We will see.
I mentioned to Seth how nice it would be to be able to maintain data with GIS technology and then we could *really* get an idea of just how agressive some of these invasive species are. The blackberries are nice for fruit (the fact that they are growing wild means we don't have to tend to them!) but in open patches that haven't been mowed, fresh green growth is shooting up all over the place.
I have a few plants around the place that I still haven't identified. There's something Ronnie calls "tea weed" that I haven't been able to find out about. That grows just as wildly as the thistle and the tallows. Maybe I will take a picture sometime and someone will be able to help me identify it.

Ah yes, and the hens made it through the night. I hope we can set something up for them this weekend.
