Dallas and i went to Washington state a few falls ago and collected a few treasures from our hikes. Finally going to get around and try to stratify and start these chestnuts. Hope they aren’t too dry or old to sprout~
Today’s (June 19) chores were frustrating and exhausting – hopefully, i won’t vent too much, but instead methodically record what happened and what decisions to make based on the mishaps. However, the first of the morning was spent walking in 3 Angus heifers to attach Estrotect patches in preparation for AI (artificial insemination) over the next weeks followed by spraying off 30 gallons of Surmount chemical mix on woody brush at my farm. Started about 5:30 am.
This late spring I started letting my cows graze the new seeding implemented last fall. It’s been super, super dry (until today! already 8/10s of an inch and still gently raining), so using a back fence was not important since the grass wasn’t trying to grow back after grazing because of the heat and dry.
Nevertheless, I’ve been stripping off sections of about 2 days grazing each – no where near what could be considered mob grazing, but i’ve already decided that is a practice which simply won’t work for me. I had already set up 2 temporary fences of polybraid of about 1/4 mile each. Anyone who has done this realizes that that 1/4 mile of walking turns into at least a mile by the time the poly is unrolled, then walk back to get posts, then set up posts along the poly and hook the handle into a hot (electrified) lead.
When i arrived this morning, the cows had blasted through both of them!! I was not a happy camper to say the least. Thankfully, i had brought along another 1/4 mile roll of poly braid and I pushed the cows sort of back where they belong and i unrolled this tape. The grass and weeds were tall, so it just sort of laid on top and looked like a fence the cows didn’t want to bother. Testing the lead, i found that there was no electricity. Ah ha! all the polybraids were ‘dead’ and with baby calves running around, it didn’t take long for them to run through with mommas right behind.
But why was the fence dead?
I had spent some time at that very spot repairing some wire and gate just 24 hours before. Why did the tree not fall while i was there? Only by the grace of God. Not only that, but my spinning jenny was unharmed and the end post was still in place! Only one gate handle and the top hi-tensile wire was busted. Easily repaired that. Plus, the tree fell in such fashion that i didn’t even have to move it or cut it up. (thank goodness because i didn’t have my chainsaw on this trip). I simply repaired around it. It will have to be removed when i have time.
But this also is a prime illustration as to why forests, timbers, draws, need managing! Treehuggers take me to task for removing mature and junk trees. But without management, trees can become diseased, can’t compete for sunlight and nutrients so they can die and are a major hazard.
Anyway, back to my morning winding up. Once all was said and done, i’d walked at least 5 miles in tall forage, scratched through dense brush, and crawled in and out of deep ditches to retrieve all my temporary fencing and posts, finishing the morning installing a new rain gauge, checking my replacement heifers, and resetting an end post.
Dragging back to the seed plant, refueling the JD Gator and using forced air spraying out the seed heads from the grill (this must be done to keep the Gator from overheating), unloading the reels of polybraid and a bunch of posts. I forgot to take water with me and by noon (got home), i had lost 4.2 lbs. Goodness, that is 1/2 gallon of water sweated out!
This was another reminder of why mob grazing with multiple shifts per day will not fit with my schedule and quality of lifestyle. It’s just too stinking much work – i sold off the sheep to get away from so much exhausting work. With tall grass (not complaining), deep ditches, long stretches of temporary fencing, dense brush, and baby calves not trained to electric braid, there are simply too many bugaboos to make this a happy time. The mob currently has about 20 acres to relax and graze. It is what it is – i do the best i can.
Another super helpful article with great ideas from On Pasture. My ongoing logging activity has yielded far greater returns than expected since my logger has found buyers for specialty logs which resulted in more money for both of us! Plus helped the specialty buyers keep their mills going. Although my logger can remove and use some of the trees for firewood, there is still a massive amount of firewood type logs which will be burned up if i can’t find someone who needs firewood to come in and cut it up and haul it off. Seems like a waste, but there is not much use for firewood quality logs anymore. (and these are already safely on the ground!)
One of the things that really impressed me (Kathy) on my April visit to Greg Judy’s place in Missouri is the thoughtful way he turns forested areas into silvopastures. In addition to creating great pasture, he turns trees into money by selling it as timber, and uses left over limbs to grow another enterprise – shitake mushrooms. I think other On Pasture readers could do the same. So with this week’s Classic by NatGLC, here is Brett Chedzoy with suggestions for getting started at your place.
Throughout most humid regions of the US, the landscape is dotted with old farm fields and pastures that today grow trees and shrubs. In some cases, there are obvious reasons why land was left to revert back to its natural state – too wet, stony or steep. But many of these old field sites also grew back because the farmer no longer had the means or needs to keep the land open. Regardless of the underlying reasons, many of these what now appear to be woodlots (or brushlots, if that’s the image that comes to mind) present ripe opportunity for productive and profitable grazing system expansion – especially when adjacent to existing pasture land, or available in large enough blocks to support a viable grazing operation.
There are many variables to consider when evaluating the potential of bringing idle land back into production for grazing. For starters, the land must be accessible and “fenceable”, have a developable source of water, and be potentially productive enough to offset the necessary investments. If you can’t check “yes” to these questions and there isn’t a reasonable fix, then look elsewhere for the time being. The next step is to come up with a (simple) plan for what will be done, who will do it, and when. Making sure there’s a good “why” is also a recommended part of this planning. In other words, will it pencil out and contribute to your objectives?
The following are some of the important considerations for reclaiming former farmland:
Are there trees and shrubs worth leaving?
If so, then developing into a silvopasture (openly-wooded) pasture may be the best option because quality trees can cultivated as a future cash crop while at the same time provide shade, browse, watershed protection and many other benefits. And if grazing is the objective, why spend money clearing trees today that will yield profits tomorrow?
How many trees should be left?
Silvopastures, like many things in life, are all about balance. From a forestry perspective, favor trees of good value, vigor and quality that will continue to significantly appreciate in value. Trees that are of firewood quality today – and will only probably become larger firewood trees in the future would be good candidates for culling, unless there is some other justification for leaving them. Some examples would be unusual species, or trees with special wildlife value like a nesting cavity or den. Silvopastures vs. woodlots can be thought of as a choice between growing the best trees on a given location together with either forage (in the case of silvopastures) or firewood (in the case of woodlots). For silvopastures, the firewood-quality trees are removed to reapportion sunlight to the ground level to grow quality forage plants. Getting enough sunlight on the ground is a critical step in silvopasture development, so avoid leaving too many “good trees”. Consulting foresters can provide invaluable expertise when contemplating an extensive woodlot thinning.
What about all that other green stuff?
Trees intercept some of the precious sunlight needed to grow forages in the silvopasture understory – but so do all of the other plants and shrubs already growing there. Some of these plants and shrubs may be quality food sources or enhance the silvopasture in other ways. Others, however, may detract from the silvopasture because they are unpalatable, potentially harmful, or too aggressive in their growth habit such as the so-called “forest invasive plants” like multiflora rose (although there are also many native plants that can be problematic like some species of ferns). The “low shade” from the shrub & herbaceous layer is often more of an impediment to growing quality forages than the “high shade” of the main canopy trees. And unlike the culled trees that can often be utilized for things like firewood or sawtimber, these smaller plants are usually costly to control. Mechanical, chemical and organic methods such as burning, shading (solarization) and livestock impacts (trampling, girdling, defoliating and rooting) are all options to consider for removing the lower interfering vegetation. Usually, a combination of these methods will give the best results.
Heavy livestock can be baited into persistent patches of undesirable brush to damage and weaken the targeted plants over time, as well as to stimulate the growth of forage plants in the decomposed waste hay. In the examples below, a round bale was fed in a clump of multiflora rose, leaving the canes heavily damaged afterwards. Mineral feeders and supplement tubs can also work to lure animals into brushy and weedy areas.
So, I got enough sunlight on the ground – now what?
Daylighting the ground is the starting, not the ending point towards establishing quality silvopastures. The next two steps are to create favorable conditions for desirable plants to germinate, and then manage in a way that promotes their growth – while discouraging the growth of the undesirables. Germination requires a seed source and good seed-soil contact. Wooded areas surrounded by fields and pastures – or where there is still a remnant of forage plants – usually have a sufficient seed bank to spare the expense of supplemental seeding. Once a variety of herbaceous and woody plants start to grow in the increased sunlight levels, skilled management will be necessary to shift the composition to primarily desirable species. When open pastures become too weedy, they can be mowed, sprayed or even reseeded. Silvopastures, on the other hand, have lots of obstacles in the way that limit these options – so intensively-managed livestock impact is about the only practical tool to manage vegetation. Desirable impact with livestock can be achieved in different ways. Some examples are: rooting by pigs; bark girdling and defoliation with small ruminants, or trampling and crushing with heavy livestock that are grazed at very high densities or which are baited into brushy areas during winter feeding. Each of these has its pros and cons, but managed correctly could be an effective way to increasingly improve understory vegetation composition – without unduly compromising animal performance, welfare, tree health and other resources.
There’s a learning curve involved with developing idle land into successful silvopasture systems, so start small and experiment when possible. Resources and advice from fellow practitioners is available at Cornell’s silvopasture forum: www.silvopasture.ning.com
