Anyone know the creator of this great graphic? We are trying to incorporate it into informational signs at the Crescent City Food Forest and would like to accredit the right people/organization. I have found it all over and am having trouble tracing it back to the original creator. Thanks!
This sounds a bit like the soil and coastal climate I started working with at the crescent city food forest. I understand why you’d hesitate to build a big hugel at first, but it would be very helpful to bury woody debris wherever you may be digging and building raised beds anyhow. This will add organic matter, water/nutrient retention as exchange, drainage, and fungi that help with all this.
For this fall-winter, I’d start with fava beans (good greens, nitrogen fixation, biomass production), daikon, brassicas, chard/beets, and peas in addition to a cool weather grain if so desired (barley, quinoa) that will support the peas and pump sugars into the soil in exchange for nitrogen from legumes. Peaceful Valley (groworganic.com) is a good regional source for bulk cover crop seed (favas especially). Brassicas are so prolific as seed sources I bet you could find some in neighbors gardens or put out a request and get a bunch. I harvested a gallon in about 40min this fall! I have also had luck requesting yr old seed from local stores, including the big box guys (if they have a nice manager like our local one). Good luck!
One bright side is how many native plants germinate best in bear scat. It is used in several National Park restoration programs. I am assuming you are talking both black and brown/grizzly bears where you are so I would not mess around with too many experiments, but I have heard from Mike Mcgrath on the You bet your garden podcast that a motion activated talk radio (More obnoxious the tone the better) can be worth trying. I’d really consider electric fence with multiple LGDs if you really want to keep fruit trees, which are essentially feeding making them problem bears. In the long run I might try the Mollison described fruit tree embedded into blackberry thickets method.
Regarding how Paul and Allen would manage 1million acres of western Oregon timber land, points about Northwest coniferous forest ecology and hydrology were at times quite inaccurate by my understanding of the current science (they did only have 30min prep), but many of the points in this podcast were great. I have always particularly liked Paul's main idea of moving many permies onto the land so it has more stewards/acre. Done well, this infusion of beneficial keystone species (permies) would be a vast improvement compared to the ridiculously low current # of Forest Service employees/acre. Being so stretched thin is what seems to prompt many unsustainable and ecologically destructive practices like herbicide spraying, monoculture, and poor fire management. I would bet this is similar on private forest lands, but should admit I know a lot less about current private practices (often kept private as proprietary) than those used in public land management.
I think it is important to note how I should grant Allen and Paul the benefit of the doubt and assume they are talking about plots with little to no old-growth left, and that they would preserve any truly ancient forests and the endemic soil species (often endemics are found in each old growth tree), unmatched carbon sequestration, water retention, fire resistance, and sanctuary they provide. Therefore I should also assume Paul is not using the straw man that is current forestry (i.e. tree farmed) land management as an argument against conifer forests’ potential ecological and human value, as that would be akin to criticizing the “three sisters guild” by means of an indictment against current corn monoculture. Old-growth forests and tree farms (as much of or national forests and private forests are managed), are qualitatively different, but I again feel the need to defend conifers’ integral place in health NW ecosystems. Despite native burning and preference for oaks and other deciduous trees in many places, the NW still had the vast majority of its land covered in conifer forests that had the highest biomass/acre of any place on Earth (10x tropical broadleaf forests). On the other hand, “forestry” lands are now either mono crops or are largely very low in species diversity, and even diversity within species is horrible, with many large swaths aerially over-seeded with very narrowly sourced genetics of just Douglas fir. Fires are suppressed entirely to protect short term profits. Private and publicly managed forestry lands are also subjected to herbicides to remove integral support species like alders, willows, and bays that are misconstrued as competitors for light, water and nutrients instead of as hosts for nitrogen fixating and nutrient chelating soil microbes. This makes these forests less healthy, less able to retain water and produce sap to repel insect pests that then leave them as dead ladder fuels. I think Paul’s preference for “woodland” over “forest” as a more permaculture friendly term, despite how the former embeds the resource to be extracted in the name “woodland” and implies that as the sole value thereof, reflects just how mismanaged many of our national and privately owned “forests” have been. I would argue tree farms are not forests any more than a corn field is a prairie. I would have liked a little more specificity about the nature of the forests they were inheriting was, but again they only had 30min to think about this and I should cut them some slack.
Within their 1million acre plots, Allen makes sound points about conglomerating settlements (I’d imagine around water) and allocating large contiguous areas for intact ecosystems (zones 4-5) to allow for other keystone species’ return. These would include beavers, wolves, grizzlies and salmon.
However, conifers are also a keystone species in NW ecosystems, and I would assert far more than 5% in 1/2acre groves (Paul’s suggestion) would be necessary for the system to function. The primary reasons for this are related to how conifers are particularly well suited for the NW climate, with its mild wet winters, dry summers and regular fires. These mild wet winters allow for coastal conifers, with their A-shape suited for low sun angles, to grow just as fast in January as they do in June (Noss, Redwood Ecology, 1998). Deciduous trees’ shapes are much better suited for high sun angles of summer, when we have little to no rain. Moreover, conifers holding their leaves/needles through the rainy season makes them much better at slowing, spreading and sinking water than bare deciduous trees. When in the BBB Mollison refers to the peak water holding capacity of ancient forests, where it can take 70yrs for a raindrop to reach the river, my understanding is he was speaking of coastal redwoods and other NW coastal conifers. The assertion that conifers dry up streams was a common logger justification for cutting them, and their evidence was how often the rivers beneath the forests swelled over their banks in unprecedented ways after logging. This obviously neglected how the biomass of the trees removed and the soil they held would have been holding the rain through into the summer to humidify everything downwind, and in the soil for decades as it seeped downstream through innumerable lifeforms. The dog-hair second growth would then also grow as the streams eventually dried up due to the loss of biomass, reinforcing this misconception that conifers dry up streams, despite how healthy coniferous forests’ bottom layer used to always be a healthy salmon or trout bearing stream. These fish were the primary food produced by NW native forests that were dominated by conifers, but also hosted a diverse array of understory broadleaf trees that also produced significant food sources (hazel and bay nuts, acorns, huckleberry,). Where I live now in NW CA, also hosts the highest botanical biodiversity of vascular plants (300+/hectare) in North America, and the canopy is dominated by the most diverse array of conifers on earth (23). I plan to embed food forests and holistic management practices with animals in and around this native bounty.
Montana seems to vary greatly from Western Oregon/WA/CA in this factor, but the NW coast of the US is also one of the least lightning prone regions on Earth, allowing for trees of greater height (and with it upwards of 10x the collective biomass/acre) than native deciduous trees ever achieve (I don’t think we’d want to introduce the only comparably tall broadleaf, the fire prone eucalyptus). The biomass of these coniferous forests can therefore hold vastly more water than a deciduous forest ever could. These native NW forests evolved to do this likely in response to wet winters and dry summers. This water held from winter rains by massive conifers provides the majority of summer humidity and precipitation inland all the way across the continent (Mollison), as the trees transpire up to 500gal/day (Noss). Moreover, due to their growth period (spring-summer) being largely during the dry season, deciduous trees in the NW can only grow near water, where they also get columns of light through the coniferous canopy. For similar reasons, larger native deciduous trees like big leaf maple, alders, bays and Oregon white oaks often have beards of beneficial moss and lichen to hold winter rain into the dry season for them to absorb through roots that form between their trunks and the moss. Many non-native deciduous trees are not adapted to do this and can die from rot if moss and lichen growth on their trunks gets excessive. Fighting against the NW climate’s selective preference for conifers, especially on slopes and the coasts, seems like rolling the rock uphill. Of course I would love to build food forests dominated by deciduous broadleaf trees on the south flanks of conifer canopied groves and forests, but on any slopes over 15deg and where human access is difficult I would allow evolution to take its course and this will almost always favor conifers for the reasons mentioned above. However this all varies greatly based on the health, age and state of succession of the forest we are talking about. If we are talking about a dog-hair Doug fir regrowth monoculture, I would say Paul’s suggested treatments for selective logging and using the wood for building, hugelkuture, junk pole fencing and other permafications are appropriate.
Why might I not be written off as a dumbfuck? I have intensively studied and worked in NW forests for over 15yrs, in addition to hiking a great deal of the west coast (thru-hiking the PCT, spending a decade of summers working in NW forests as a backcountry, interpretive and ed ranger, trail crew member/leader, environmental educator, and restorationist). What I do know about our local private logging practices comes primarily from a 30yr veteran forester for Green Diamond, and from knowing many loggers, foresters, biologists, botanists and ecologists. I have also talked with quite a few native (mostly Makah, but some Clallam, Tolowa and Yurok) friends extensively about their traditional practices, as well as reading about them quite a bit. I do not know it all of course, but if I know anything, its NW forest ecology. I have applied this background to my study and practice of permaculture for the past 7 years, and am now the food forest site developer for Del Norte County and adjacent tribal lands, and a co-founder of the Wild Rivers Permaculture Guild. Therefore, even though I listen to pretty much ever podcast Paul puts out, the idea of managing a million acres in a permaculture way to work with fire particularly piqued my interest. I was disappointed to hear some common misconceptions about conifers, or at least assertions that deserved some contextualization. I don’t expect anyone to get everything right, and I hope this feedback is taken as constructive. If you’d like my source material, I could dig it all up, but I’d start with the books Conifer Country (Kauffmann) and Redwood Ecology (Noss), which of course are focused on NW CA and SW OR, but they also cover many associated species and ecosystem dynamics common to Oregon as well.
Congratulations on starting the journey. My only tropical experience is in Samoa at the University of the South Pacific Agricultural Campus in Alafua, and a month Fiji at my USP roommates' family farmstead (he was the son of the high chief of NW Fiji, so this was pretty extensive). I've never been to the Philippines so take that into consideration.
Wild onions were a staple in Samoan food, with it being integral to the wonderful coconut cream-wild onion dish used as an almost ubiquitous condiment with taro, breadfruit, fish etc. Root crops other than Taro did seem to have trouble in much of Samoa due to compacted clay soils from heavy rains stripping topsoil and pounding it into brick when it was exposed following deforestation. In Fiji, sweet potatoes were grown in mulch mounds, likely to get above a similar hardpan.
The Peace Corp and UN Ag folks were pushing the proliferation of nitrogen fixators like pigeon pea, peanuts, etc, and the starts/seeds of these that I brought to a host family for a month-long research project took off quickly with no help from me.
The rainforest chilis growing all over both Samoa and Fiji must not be native as these plants came from the Americas originally, but are the best hot peppers I've ever had. Just chilis, onion, and salt in water made a great dipping sauce with roti, taro or "curry in a hurry" (taking only 3-4hrs!) that my Fijian neighbors would make on long leisurely Saturdays. I miss those guys and that was some of the best food I've ever had, but I do not miss the Samoan heat and humidity!
I agree with the coppice and pollard suggestion as the ideal option. The roots will die back proportionally to what you cut back, essentially injecting compost full of rooting hormones and enzymes (being a willow) into your soil. If you do need to cut it down (which is not the permaculture ideal in most cases according to Bill Mollison), you could always help that tree live on as an easily rooted cutting somewhere more suitable for you. If we are growing food as an economic necessity, it's hard to judge someone for cutting down a non-edible/medicinal tree shading the only place one could garden. However, if we are growing our food for the environmental reasons like many permies do, I think it is incumbent on us to consider other places we could garden that would not require removing trees, especially large and old trees with ecosystem services far greater than our gardens would provide.
Even oft vilified conifers have immense ecosystem services, as their needles can have many acres of surface area for slowing, spreading and sinking water, cooling waterways and land, as well as providing habitat for extremely diverse soil ecosystems (in fact the most diverse on Earth are in old-growth coniferous forests of the NW). That being said, an old-growth forest is qualitatively as well as quantitatively different than a tree farm, backyard, or street-side tree. I have removed many small trees of many kinds around my house that can act as ladder fuels in fires, so I don't mean to cast any universal condemnation of tree cutting. I just encourage thinking about what we are doing this gardening for, considering how long a tree took to grow, and its many services to us and other living things. Kind of like we benefit from considering long and hard whether we want to liquidate an investment account that took decades to grow, and make sure its for something worthwhile long term.
I'd plant them in their final location if possible, to let winter moisture help them develop a root system tied into the water table to survive the next summer. That's in my climate though, where we have mild wet winters and dry summers.
Where you are in Denver, I’d probably avoid frost pockets. In other places that would never see killing frosts but need as many chill hours as possible, or to avoid early bud break due to warm winter temps and spring frosts/hail, frost pockets can be useful/acceptable in my opinion. Where I am in NW CA at 1500-1800ft, with low temps around 15-20f most years, 0-10f is probably the 100yr low as my educated guess and many fruit trees would never die in this but benefit from avoiding early bud break on our sporadic but fairly regular “Juneuary” warm winter days. However this is a remote area with widely diverse microclimates. Like many oft vilified natural phenomena that can be avoided or enhanced with design, frost pockets have their place.
In general, I do not worry about weeds from worm castings. If you are worried about it, id go with the heat suggestion, or you could also let them rot/ferment in a barrel of unaerated water, then dump all that over the worm bin when it could use the moisture. You could also sprout them on a tarp or in aerated water then dump onto the bin for the worms to eat.
I have found they eat weeds and seeds, and produce great castings after. I haven't figured what may survive their digestion, but its a small minority of seeds. I speculated seeds that may sprout in the castings are likely those that are extremely small, or those well protected by a coating or mucous (ie tomatoes seem to grow out of my bins).
If you are short on seed and want to help get better germination rates, you can make seed balls following Masanobu Fukuoka's directions from One Straw revolution (basically rolling diverse seeds in 90%clay/10%compost). Spread seeds or seed balls and mulch if soil is bare. If it is covered in weeds/grasses, spread seed mix or seed balls before rain, then cut back weeds/grasses as coarsely as possible and use that as mulch, adding more organic matter if necessary to cover seed. It the grass is in a thick mat, this is the only time i'd consider shallowly tilling/flail mowing once where tree roots won't be damaged.
Antonio, I just connected that you were the one with the post from Valencia, Spain. It's so good to hear about that part of the world where my Basque ancestors came from getting some permaculture reinvigoration from people like you! I imagine the Basque and Catalan cultures both must have had a great deal of permaculture friendly traditional practices (one of which I know of being the Cork Oak-Jamon Iberico silvo-pastured pork production that sounds a lot like holistic management to me). I would try to learn as much as I could from remaining traditional native practitioners and historical documentations of what worked there for over ten thousand years for the Basque and Catalan people, much like I am trying to learn from the local Tolowa here who stewarded the redwood coast so well for a similar amount of time. I also understand the moorish influence on agriculture in Spain had some very permaculture friendly design elements (swales planted in summer, berms in winter). Best of luck!
"Four distinct management groups organize the cover crop diversity. 1) Cool-season grasses like wheat, oats, and triticale; 2) Cool-season broadleaves like canola and sweet clover; 3) Warm-season grasses like hybrid pearl millet and sorghum-Sudangrass; and 4) Warm-season broadleaves like sugar beets, cowpeas, soybeans, and sunn hemp. He advises to set the drill for the largest seed." (He has a fancy seed drill that allows him to plant upwards of 70 species at a time without tilling).
These are good questions Antonio. It will help others provide locally appropriate answers for you if you put your general location, elevation and zone in your profile.
That being said, I have gotten plenty of good insights from farmers like Gabe Brown and Sepp Holzer in vastly different climates from mine. Generally, its hard to go wrong with diversity in all dimensions, including plant species and families, growth habits, height, root structure, climatic preferences, and seasonality. Gabe Brown emphasizes representation from five main families (much like the old NY crime syndicates;):
1) Amaranth (including sunflowers, buckwheat, spinach)
2) Legume (beans, peas, clovers)
3) Brassicas and mustards (ie cole crops like kale, collards, cabbage)
4) Grasses (as Bill Mollison said, "save your money on grass seed, they will come on their own!")
5) Borage family (phacelia, borage, comfrey)
I'd add in some squash, potatoes (under deeper mulch), and anyhting else you could hope would grow in your climate and season. Then cover with a 2-4" (less with small seeds, deeper for larger seeds) mulch of straw, chopped and dropped weeds, shredded leaves, pine needles, palm fronds, or any other loose organic matter you have cheaply available. Sprinkle in some compost or spray with compost tea if you can for microbe inoculation. You will get plants naturally selected for your context and methods, and significantly better soil the next season and beyond.
I don’t think I can fully answer your question or that I even fully understand what your question is, but I’ll give a short summary of how I’ve applied what I’ve learned from Geoff Lawton’s videos on his website and the PRI’s. As I understand and have applied his methods, we are mimicking natural processes in which seeds are dispersed in a carpet with much higher numbers than could possibly all survive to reproduce, and then fall leaves and duff (mulch) cover them instead of soil. So we broadcast a dense carpet of legume and diverse other seeds and then covering with a loose light mulch that strong seedlings can push through, ideally before or during rain. We will then have natural selection take its course and the seed that form on our plants the next season will have been selected for suitability to this method and our climate. So we only have to buy or acquire the seed from outside once, quickly balancing out the extra cost of overseeding at first, and that extra seed is itself an excellent veganic fertilizer. I have also found that bulk fava beans, if bought in bulk, compare well in price to other organic veganic fertilizers that provide what the beans do, even if the seeds just decompose. This is even more valuable as a complete fertilizer if it’s diverse array of seeds like buckwheat, brassicas, grasses and wildflowers. Also, by that second season we will have biomass for chop and drop mulching over our home grown seed, and as our trees and shrubs grow this will increase. Hope this helps.
1200$/week would be a good deal in my area for the small-medium sized bobcat excavator (15,000 lbs). I would however not bother pulling a stump if I were simply going to use it for a hugel in that same spot. I'd just use it as the base of the hugel, or as part of a larger one. If you plan to do something else there and have the time and cash, the excavator I describe could do the job easily in much less than a week, so I may consider how I'd use the rest of that time on ponds, more hugels, swales, woody debris filled trenches, etc.
I am pretty sure swales are not advised on slopes above 15deg, and are especially precarious with clay soil as when saturated it is prone to slides. Permanent tree cover, ideally with species that have leaves present to slow and spread rainwater during the rainy season (meaning evergreens in the Pacific NW I’m in) is the best watershed management practice according to many sources I’ve read (Mollison, Fukuoka, Loess Plateau Restoration protocols, NRCS). This is also what nature does when left to its own evolution. At least tree planting is less work and safer than making swales, but probably not what you want to hear. It’d be good to plant before your rainy season and choose varieties that need no irrigation.
Oh, I’d also host or join some fruit juice pressing events and take the mash home to plant where you don’t plan any other earthworks or buildings. Sepp Holzers advice, which I’ve followed with success, is to spread the mash on your poorest native soil, cover with mulch, and let nature select for the strongest tree for that spot amongst thousands of seeds.
If you have done any of this already, good on ya, but here are some resources I’d check out:

In terms of general strategies: access, water, earthworks/soil in that order. Access allows all the work on the latter parts to be easier and more efficient. Water is necessary for any life we want to support, and understanding our water needs and devising a master plan for water flows on the site will inform our earthworks design. Soil will form and stick around naturally with sound water management and earthworks design. Beyond that, keeping the ground covered with organic matter living or dead is the basic principle I follow. No BS (no bare soil)! Manure from male cattle is fine though
Thanks y’all. I really don’t want to kill any wildlife, especially predators that keep ecosystems in balance, but I do love my Wilson more than anything! I agree that killing snakes that rattle makes a vacuum for those that don’t. I think they have been attracted by the mice/pack rats that invaded/exploded while the house was unoccupied by a cat during our move. If you look at these pics or my post on the “Show Me Your Gates” thread, you may see why removing rock piles is not really an option. I don’t know how else I could hold up the fence other than rock jacks.
Anyone know where to get a few hundred gopher, rat or king snakes (they eat rattlers)?
I have seen two rattle snakes near my house in the past ten days. The first was under our deck abutting the house. Our Pyrenees-akbash Wilson went to sleep down there out of the summer heat, and bolted out when the rattle started, then started barking and stomping right above it on top of the deck. I got dressed for the job and moved the snake outside the fence and got it to slither away further with a hose. The second was a smaller snake in the brush outside the fence and above our driveway. Both alerted us with rattles well before conflict occurred. I know that killing snakes that rattle in warning has shown in a Washington State University study to basically breed snakes that don’t rattle for humans. We also have pretty hardy dogs in Wilson and a Doberman we are fostering that was raised on the property. However I have considered killing the snakes and feeding them to the dogs, cooked and beheaded, of course. I am torn. I’d feel horrible if we lost a dog to a snake, but wonder if killing one that alerts us to its presence really reduces the risk. Your thoughts?
I have to agree with Rene. It seems like everybody here have admirable intentions, and I hate to say what’s “not Permaculture”, but Bill Mollison was explicit in saying that clearing a forest to garden in its place is not what he intended. That being said, some woodlands are not the native polycultures they could be, and that could warrant utilizing the harvest of trees for infrastructure while simultaneously performing ecosystem restoration. Many areas over seeded with dog hair Doug for around here come to mind. I agree with the posts above encouraging working within the context of the site, and finding one with potential in line with your goals will be key to success. I also agree with the encouragement to underestimate the work you want to have to do to make it work for you. Don’t chain yourself to a property, when the right one can instead set you free. Best of luck.
How bout the HHH "hot, heavy heater." Kidding, but can't think of anything better
I do think that despite the wealth of great insight put into the Rocket Mass Heater, this probably sounds like something dangerous and enigmatic to soccer moms, and this is a big reason why it is not catching on like we'd like.
Just saw your last response, and yes manure mixed with wood chips will gas off nitrogen when on the surface together. However, nitrogen is basically free, as it’s about 4/5 of our atmosphere. We just need to help the soil fixate this N, and the manure and woodchips will be the perfect habitat for fungal inoculation, which can be as proficient at N fixation as any legume. You could let nature do its thing or inoculate the woodchips with king stropharia or blue oyster mushrooms, which inhabit a wide range of wood. I’d also grow legumes in almost any bed, and strongly recommend Scarlet Runner Bean if in zone 7+ where it can be perennial.
I have done this before and agree with the comments above. It will probably make your results from the compost/manure additions slower but longer lasting, generally a good thing long term. If you wanted more immediate benefits from the nitrogen in the manure, you could take the chips aside but I’d just water it through the woodchips. It will also break the chips down faster. I have also always seen good results with manure/compost teas watered in through the chips. The woodchips also make it easier to water more assertively, as I can use a much stronger stream from an open ended hose and the chips disperse it and prevent compaction/erosion. I generally make a fairly strong compost tea, add a modest amount around any garden beds I want fertilized/inoculated, then water that in through my woodchip mulch.
Pond water is my go to for nitrogen and a soil life boost. I currently have a pond with goldfish that have bred prolifically from the initial introduction by the prior owners grandkids. I have also used Muscovy duck pond water with great results, and the ducks provided a good amount of phosphorus too. I would usually make this the base of an aerated compost tea.
“It is pretty hard to get perfect grazers. Inevitably they will leave some of the grass and weeds that they do not like behind. Most of the time weeds are late in going to seed over that of grasses, so it is nice to go out and "clip" pastures which kills the weeds before they go to seed. Doing this really improves the field because it is both Chop and Drop, and Rotational Grazing. Within a few years of clipping pastures at the right time, you will get really thick stands of sward.
The maintenance on a tractor is not that bad. As I said, I put a clutch in mine for $300 in the 20 years I have had it. A few front tires, and some odds and end mechanical work. Its been under $1000 in maintenance costs in 20 years; or the equivalent of buying about 5 sheep at todays prices. It will take well more than 5 sheep to mob graze any pasture! I bought mine in 1999 for $14,200, and it is worth about $9,000 today. So in twenty years it has a total cost of about $6,200. It also has just shy of 3000 hours on it, so it has an average cost of around $2.00 per hour. To me, my time is worth more than $2.00 per hour.
As for my BSC, I bought it used for $500“ - Travis
I love this idea, having played around with quasi passive structures for a few years now. I do have a couple questions (hopefully I’m not being redundant with another persons inquiry):
My first reaction to the design drawings was, “that seems like it will be very cozy in terms of temperature, but will it provide enough light for optimal plant growth?”
Have I missed some research on how little light many subtropical (like those that need greenhouse in MT) plants really need? I know a lot of shade loving plants would do fine with dappled partial sun, but it looks like mid summer sun would only reach the windows for a couple hours on the shoulders of the day. I think most subtropical fruiting plants would benefit from more light than this. So just some observational data on such plants’ (ie tomatoes) growth, and whether they get leggy or stay nice and stout would be greatly edifying. Thanks for putting in the work!
I generally translate the recommended seed depth to the depth of mulch I put on top of the seed. Correlating with what was mentioned above, small seeds get only a light sprinkling of straw, larger ones like squash and runner beans get up to 2” of straw or woodchips.
Something mentioned above about the Ruth Stout method using hay, when I thought it was straw (to reduce weed seeds). Am I mistaken?
Birds are major phosphorus transporters in many ecosystems, so their manure would be helpful. Long term consider providing bird habitat. In the short run some seabird and bat guanos are great tea additives. For your bioavailability, I’d make a tea with the above, some of the best compost you can find, worm castings, kelp, and oats or barley for microbe food. This will make any nutrients already there more usable for plants and add a little bit of everything plants need.
I am sorry to see your bad luck. I agree with Marco and would look to harvest that excess of protein and frass with birds. I doubt you could really do anything about the swarm itself and protecting your garden seems a lost cause. You should have some great bird song and fertile soil soon though!
