TreeYo EDU new Article Release: State of the World

To conclude Chapter 1, finally, of my online book, TreeYo EDU, I give you the State of the World article. Fitting timing after yesterday. Its a part that every Permaculture Design Course has in it and i offer a patterned based approach to the perspective. Its a pretty fun read i have to say and i hope you enjoy and leave comments on all the great projects that are going on around the world as i ask for in the last sentence.

Desertification TALK

There is something big happening in southern Europe that is not getting enough air time and I believe it requires our attention. Check out my presentation on desertification at Danyadara to find out more. Just add your email and you get a link the talk I did on the topic. Thanks to the folks at Danyadara for putting it into a viewable presentation.

TreeYo EDU article release from Patterns Chapter

Overbeck Jet, Von Karman Trail, Eckman Spirals

Getting one step closer to finishing the patterns chapter with this article for TreeYo EDU online PDC handbook. Its a short one but some pivotal patterns to understand and apply. Excerpt from opening line: As patterns build upon themselves and approach the fractal realm, they become increasingly complex in structure yet equate to simple forms with their subsequent dynamic energetic exchange.

Rainy Season Ending Final Push: Suryalila Retreat Center project Update: Southern Spain

When I showed up again at Suryalila on April 20th, 2017 I had just finished a one month stint of being on the road in Portugal and felt refreshed to be back there in Southern Andulusia.  To my surprise the landscape had already taken on a harsh look and the weather surprisingly hot.  There wasn’t much of a spring, which

made the winter crops bolt quickly but the soils still a bit too cold in our new sunken beds for really great growth of summer crops.  However we made some mulch, bed prep and watering adjustments and began to plant out the garden further along with farm manager Jacob Evans.  And not just him but a wonderful crew that evolved and emerged as a serious squad.  I supported them with lots of education and they supported the project and myself with lots of hard work and laughs.  And not just outside in the field, but also inside building the association of Danyadara Permaculture further so that a true educational center surrounding permaculture can be lifted up off the ground.

It really didn’t rain much from March 3rd to April 28th, maybe one inch (25mm).  That makes life tough when you have so many new growing spaces and young trees.  You need that water for the growth of biomass to cycle, for animals to eat, for trees to get established, and crops to be nourished.  Watering with well water is just not the same as rainwater, which is what we saw when it finally did come a couple of times during my time there.  So we just cracked on with planting, watering, managing cover crops, composting, worm bin maintenance, earthworks adjustments, plant propagation, animal husbandry.…  the list goes on and on.

Kai, Anna, Amelia, part of the crew working on turning one of the many piles we built and managed during this month

We did some implementation of sunken pits (a form of sunken beds)on the swales we installed in December and on the Moonshala terraces we installed in the PDC in March.  We worked hard to get this done by simply creating a small sunken crater and putting seeds of squashes in just before a rain.  However the rain ended up being very little amount and the hand watering began.  The germination rate was ok and again proves that rainwater is such a quality version of water and with shifting climates this is one of the repercussions, lack of good germination.

However we did get one big three-day rain event exactly one year after the big rain event of May 10-20 that happened last year in Iberia.  It wasn’t ten days this time but we worked like mad for days before to install even more growing space in the old wheat field.  The wheat field had been subsoiled twice on the

11 months ago, late June 2106, the wheat field looked like this, a monoculture of wheat has just been harvested for the last time

keyline pattern in the last six months and was ready for its next step to happen.  With trees planted thus starting the alley cropping and with animals rotated to cycle biomass, it was time to create gardens in the alleys.  First we grazed the field in a rush with a couple of horses and the biomass they didn’t eat we harvested for hay for the other animals in different pastures.  So we used the subsoiler once more going off contour during the first passes then back on the key line pattern after that to break up the ground further and set the beds.  Then we weeded the long rows of the mainly annual vegetation and then tilled. While tilling is not the best for the soil, well, sometimes you got to do it in year one and especially when you are in a hurry.  As we were tilling, we were following behind making sunken craters once again to accommodate squash but also with sunflowers.  We incorporated manures and then topped the craters up with a light application of compost after the seeds were sown just hours before the rain came.  The crew was amazing with this implementation of the wheat field garden with others from the retreat center community coming out to support the final push as well. At the end the beds looked like terraces, following the curves of the valley which contains rich soils.

And the rains came, terraces held water, swales captured water, the keyline pattern cultivation infiltrated water, the sunken beds, the pit gardens, all of that digging and mounding by us and the machines was in full action.  Crops grew with amazing speed and biomass was springing forth.  It was a sight to see for sure with 2 inches (50 mm) of rain coming over three days.  And quickly it got hot so the rush to chop and drop and lock that moisture in through mulch was the next big push.  And to get the place looking great for a big yoga group of 60 people that came just days after the rains stopped.  Me and Jake gave tours to that group and a sense of inspiration from nature was present.  We have indeed transformed the landscape there through so many approaches that I feel quite proud of my work there along with so many people. Furthermore, with the wheat field we planted out a couple of more long rowed beds on this same implementation pattern but mainly just planted on the level ground with tomatoes, peppers and eggplants.  It should produce an abundant supply of food if summer doesn’t come too quickly and the crops can shoot after the transplant shock.  Overall the wheat field has gone through an enormous transformation in 11 months and am impressed with the speed of progress we were able to achieve.

Me on the broad fork keeping the gardens beaut!

And my inner landscape was transformed once more forever.  It’s a place where living life in community brings up a lot.  It’s practically impossible to escape.  And thank goodness because when your eyes and ears are open lessons are abundant.  I left with this Mollison quote during my final morning meeting “the greatest change we need to make is moving from consumers to producers.  If only 10% of us do this there is enough for everyone, hence the futility of the revolutionaries who attack only with bullets and words, not shelter and gardens.”  We became producers of groundwater, of biodiversity, of soil, and of food.  The mantras fused into two, lets plant some treesyo in the winter to the spring lets grow some foodyo.  But most importantly probably, we were producers of community.  It’s the people you remember the most over the years not how many trees you planted or your yields per acre or hectare.  And this crew, this epic journey of pushing as hard as I could for four straight weeks, and all the other amazing people I met through the retreat center, well it taught me a lot and reminded me just how blessed I am.

Danyadara: Suryalila Permaculture Association

No time to do many updates as spring planting of the veg gardens and taking care of the nearly 1000 trees planted this winter keeps me quite busy. But here is a short video of the main project i am working on these days alongside an amazing cast of characters. What a pleasure to be here in Southern Spain at Suryalila with the non profit association now have been launched, Danyadara.

On the Road: Fair Share Consulting/ Implementation with Past students/ Past Projects

check in on past students and projects and being open to the future

After finishing the two week PDC at Suryalila Retreat Center in Andalusia spain and then a weeks worth of implementation work, I headed off for a short break to Grenada to rest and recharge.  I like to travel a bit to cultural cities as well to have a peak into the past and see cultural development.  While I enjoyed the rest I was quickly anxious to get back to Portugal, which I have called home on and off for the last eight years but more full time the last three.  With no base anymore I decided to line up a travel through the southern part of the country checking on past students and projects offering a hand and a creative/informative mind.   I have always wanted to do a travel like this and not being attached to any base site I was free to do it and have thoroughly enjoyed seeing their progress and am extremely alarmed by the rapidly increasing signs of desertification.

Jacquie- Ourique, Portugal

Jacquie acquired this stunning site in the last year along with her partner Neal and have been hard at work in a good pace to clean up the land and settle into a new lifestyle.  Jacquie was a student in the December earthworks and food forest Course at Suryalila and has been up to exactly that since.  Having added a swale for runoff and planting new trees she is cracking on with complimenting her already existing orchard.  The property itself is 7.5 HA and its main feature is the already existing productive trees and also the almost year round quite large stream.  It’s a very beautiful aquatic habitat and we discussed improving the riparian buffer to create more natural habitat.  You find this a lot in Portugal that the riparian buffers were long deforested and is part of the problems of water this country has.  We also looked at the nursery site that might be her future mission after much of her life being dedicated to wildlife rescue and conservation.  An obvious pond site was also observed in the two open fields that were once pasture land and have tons of potential for development.

Derek: Ourique, Portugal

Monte Velho, one of Dereks lands that he bought in the 90’s, is a 132 HA montado (oak Savannah) where myself and Jesus Ruiz implemented a 100 HA keyline operation back in 2015 spring.  Derek is not full-time at the site but is moving that way and I am encouraged by his lets just plant some trees and get them drip irrigation and lets see what happens approach.  Much of the work he has done in the last few years has been on water retention with four new dams added and the old fifth one renovated.  He is going with corridor  planting’s and is on the right track.  The leftovers of the humid acid fertilizer is still being brewed and put out into the landscape.  For sure the pastures where improved by the subsoiling and biofertilization put out.  I was amazed at the lushness of the valley’s and how most of the ridges had been improved in their pasture quality.  Cows are still being grazed not the land through a lease.  Still the rotational grazing plans need set up but he followed my advice on many things like not letting the cattle drink directly from the ponds rather have them piped out to water troughs.  I look forward to working with Derek more in the future as he has a 12 HA valley and Ridge just below the ruins that would be a showcase piece for microclimate and tree crop development.

Josse: Porto Covo, Portugal

From Ourique, I headed coastal to the coastal Alentejo area of Porto Covo/ Villa Nova de Milfontes to visit Josse on his small plot (3000 Sq M).  Josse just completed the PDC at Suryalila and was a very gracious host.  His house/ guest house had just been completed and was anxious to crack on with the landscaping part.  He bought the land a few years ago and when not working in Switzerland spends his time cleaning the land and surfing.  With that work already done we did a bit more clearing work but got set up for a mini Permablitx whilst also visiting several other projects that are covered below.  We also met up with Sam Millar from the December course at Suryalila  as he lives down the road in Sao Luis currently.  Him and others from the local community and a couple other people staying with us contributed to the mini permablitz we held on a warm Sunday afternoon.  We implemented 2/3 of the sunken bed veggie patch after the morning of designing pathways, building zones and growing spaces.  With such a small space its fun exercise in creative thinking on making things multifunctional.  He already had done a design at the PDC in his free time so we had already quite a lot to work with.  Then when people showed up for the Permablitz we worked diligently to weed a heavily infested bermuda grass patch and do the digging and mounding.  His soils are sandy but rich so we just made minor sunken beds ready to be filled with heaps of organic matter.  It was great to see what eight people could do in the afternoon which also included lots of people making connections and drinking a few beers. We finished with a great meal cooked by Josse as he is a chef and i look forward to spending more time at his guest house in the future and possibly implementing other features like a bio swimming pool, earthen mound sound break hedge, and food forest development.

Ferry and Francine: Troviscais, Portugal

As said above whilst at Josse’s we also toured several properties.  One nearby in the Sao luis area was Ferry and Francine’s Herded de Lage / A quinta property.  Myself and others like Karsten and Dan had implemented the initial design and garden/ terrace infrastructure.  Ferry and Francine, along with lots of volunteers, have been hard at work building up the amazing natural buildings since being there in the initial very tough startup point (2014).  The most amazing part of my return after so many years of not seeing it but having many past students pass through as volunteers was the growth of the trees.  The garden hedge looked great even though it had a minor set back of some goat grazing.  Also down on the terraces I was amazed by what I saw in the initial nitrogen fixer plantings that are now three years old going into their fourth.  We planted mainly casuarina and acacia and both have put off remarkable growth on the edge of the terraces.  The Casuarina were 5-8 meters tall after just three years and the acacia not far behind.  It makes for chop and drop to happen soon and also cover for more tree crops.  They will be hosting a PDC in May and I look forward to working with them again sometime in the future.

Alex- Seisimbra, Portugal

Also on the first day we were at Josse’s he graciously drove us north by a couple of hours to meet up with another student from the PDC at Suryalila called Antonio.  Antonio was a past consulting client and came to the PDC to further his knowledge and really sink into the Permaculture movement.  He is a well connected fellow and he brought us to his friends place in Sesimbra, just outside of Lisbon on the other side of the River, for a dinner as a retreat group was breaking their fast.  We had a small tour of the land mainly in the site where they are planning a raw food festival.  Our host were very accommodating and invited us to also stay for a sound journey meditation with a hand drum which was very peaceful.  We are in talks now about further consulting/ project development on their beautiful 200 HA piece of land with heaps of potential.

festival host site

Leo: Roncoa, Portugal

Our last stop was further to the north at Leo and Wendy’s place Monte de Ameira, which is a rolling hills block of 15 HA with lots of cork trees and a small winding stream that runs year round.  I went to Leo’s place last year after not seeing him for years to stop by in my travels.  Leo and Wendy were students in 2010 and he came to the food forest course last year as well after our meet up.  Last year I gave some consulting advice and upon arrival back it was time to crack on with some of those tips.  Last year was his first full year of operation in his guest house, which was quite an undertaking with also rebuilding the ruin for their house.  Leo is really well integrated into the local community of Portuguese farming community and has earned the name of the Holantejoan; Dutch and Alentejo combined.  It’s different than the expat communities that are great to see popping up, especially further to the south in the Sao Luis area.  Thus we made a big move in his classical young orchard of straight lines to get to his food forest goals.  So we weeded around the trees, added composted goat manure, added worm compost extract and mulched with green then brown material.  But then we took it one step further by clearing a 2 diameter circle with a small earthen c-shaped bund at the bottom for water and nutrient mention.  With this space created, we then implemented guilds to create the altered approach.  We put in a variety of plants that we got from a Portuguese National nursery near Alcacerdo Sal. No tree guild was the same and we manured in between all of those then covered with a light mulch as a broadcast seed was done in between the small perennials.  It was stacking in space and time at its finest.   It was a great time and I will write more on this one in blogs ahead.

Overall it was a great journey to see and now I am back at Antonios place in Lisbon looking to further connect with my community here.  I have no base but I am not without a network of people who are willing to host.  Its time to get more projects further including consulting of several clients in the area.  I will also go further with the educational material project I have been working on for years with my dear friend Anita Tirone (PDC 2012).  I will also write more on the drastic die off of cork trees that i have been seeing and with the dry spring in Iberia this year it is only going to get worse.  But I know there is a growing movement here in Portugal and in our neighboring brothers and sisters of Spain.  So we go further with launching sites, green businesses and working towards regenerative and equitable systems. And in conclusion, thanks so much to the hosts who were all gracious and thankful for the drop in.

Past Course Blog: PDC at Suryalila, Feb/ March 2017 in Andalusia, Spain

Here is the course blog from the amazing journey that was Suryalila Retreat Centre with an eclectic group and an amazing dynamic trio of teachers with Itai Goldman and Ja Cobo. Thanks so much to all of you for the learning process and the hands-on work we did to give back to the site and the earth itself. Lots of earthworks accomplished, tree planting, hot composting, and natural building.

New TreeYo EDU Article: Earthworks Checklist

This TreeYo EDU article helps to build the context of Earthworks implementation as well as the design and project management of it. It covers my years of experience doing this regenerative technique, however only when the context has been built correctly and the resources are there to complete its implementation.

To implement an earthwork within a landscape can be a rather simple choice when the correct protocol are in place for its inception.  Thus in this article we will look at some of those factors and complement it with design principles that help you to select the right earthwork in the right place from a well understood context.  While it’s a simple choice, there are many factors involved and this regenerative technique should not be taken lightly, especially when done with the power of fossil fuels and machines.

Treasure Lake/ Forest Blog: 16+ years of on and off management

After 16 years you notice the change.  Yes 16 plus years of on and off management of the forest at my families land, better known inside our circle as the lake, and outwardly as Treasure Lake.  My family has owned the property since late 1983 and lies just outside the major metropolis ti-state area of Cincinnati, Ohio.  Iimg_1509 have seen encroachment of the suburbs from all directions over the years but it never really reached this tiny corner of Boone County, Kentucky, USA.  So as the ‘burbs grow, forests diminish, water quality drops, and biodiversity is tormented by the invasion of industrialism.  But in those last 16 years at the lake, I have seen Paw Paw patches and spicebush thickets on the rise and big trees keep getting bigger.  I have been witnessing the dying of random trees, the sprouting of new seeds of hickory and oak, and the changing mosaic as the ash tree dies out.  It’s like the paw paw knew the ash were dying as they began to sprout by the weakening trees and now that the canopy break is in full swing, they are popping upwards rapidly.

16 years I have been wielding hand tools and power tools for managing succession in the 40 acres (16 HA) of forest that surrounds the 15 acre (6 HA) lake.  It started with clearing old campsites, left over

from the properties recreational area inception in 1947, which had been abandoned at some point as the property changed hands numerous times. We did this initially so we could party out in the countryside relieving us of the monotony of suburban bars, college town forays, and city nights out.  It was me and my brother and friends at first in 2000 before I headed off to Southeast Ohio to get my degree in Fish and Wildlife Management at Hocking Technical College in late summer 2001.  In 2001, my grandfather had the lake rebuilt as this 1947 Army Core of Engineers dam had burst in 1992, a tough year for the project.  With the lake being built and my spending more time out there and wanting to study nature more, but being so clueless on how, my good buddy Andrew Williamson drug me out of the city on a whim to go and study ecology essentially.  The day we moved out there was 9/11/01 by chance.

From there each summer I would come home and apply the things I was learning and study ecology  further through my families forest and lake.  My whole education was always put through the lens of slide18going back to my families land and making the property thrive and the business of pay fishing more ecological.  So I would rally my friends who were quite keen to get out of the burbs for a bit and come and chop down honeysuckle and multiflora rose (“invasives”) and the like to open the ridge tops that jut out towards the lake.  These spaces now are the campgrounds we have on successive ridges pointing south on the northern edge of the property.  Since then, I and others have been mowing to keep the edge back but it manages to creep in from time to time on these campground spaces.  The place really is a jungle in the growing season with its 12 months of even distribution of precipitation and intensely hot, humid, rainy summers there in the Ohio River Valley.  I have also been thinning trees on the edges and valleys to augment the forest composition for biodiversity, to cycle biomass, and to obtain yields of poles in particular.

Thus I have been systematically and continuously cutting back invasives, as they do coppice.  I also have been playing with the canopy to invite our native understory plants like Paw Paw and spicebush to emerge into the sub canopy as I remove their bush and bush/vining layer competitors (again bush honeysuckle and multiflora rose) and sub canopy layers like red maple (native but blankets like an invasive), box elder, black locust, and a bit of elm.  The ash is dying because of the emerald ash borer and

of course there are deaths of trees from various reasons including the veracious appetite of the climbers that I let take their natural course as much as I can.  My grandfather, before his passing, and also to support a tough economic time for the project, elected to harvest about 25 mature trees.  I worked hand in hand with the forester to make sure there was not too much taken and it was done well.  This created really large canopy breaks in some areas and altered the composition below as well of course. So in essence, I am making this 40 acres (16 HA)  of natural food forest into a more cultivated food forest.  I have only planted in a few trees like grafted paw paw, persimmon and jujube. That is an area of a broad valley where we dramatically opened the canopy for the harvesting of black locust poles for stage building for Pollination Fest and other pole necessities.  We went beyond that initial harvest in 2014 and continued to harvest that and cycle biomass from youngish box elder to open even more light for the rapidly spreading native paw paw patches.  I could have done it all in one year, especially with a chainsaw, but one of the keys I have been finding over these years is to go at a more natural pace by using hand tools as much as possible as to not create too much disturbance and invite another invasive in.  In my month stint in late fall 2016, I split my time between a chainsaw, a brush clearing ax, and a japanese timber saw to do the work I needed in the forest.  I was mainly going back over patches I had cut two to three years previous on steep hillsides, which needed this next intervention so other understory species besides the aforementioned ones could flourish as well like dogwood, redbud, and muscelwood.  It’s a much more interesting forest when these native species thrive and the invasives have their little brambly corners to be the habitat they were intended to be when brought to the continent from Eurasia.

So the species composition has changed over the years and that is the feedback loop of watching the same hillsides and valleys for 16 years.  It’s a more biodiverse place now with tons of potential for wildlife viewing of all sorts.  So even if some of my agricultural experiments have failed, well the forest keeps on growing.  I am excited for this years feedback loop as some of the Paw Paw patches had grown so thick I began to cut them back as to give more space to individual trees becoming much bigger.  They spread via rhizomes and if they don’t have enough light they don’t produce much in the wild.  I tried this in 2014 in one space near the edge of the lake where a patch was growing with basically an open canopy on this south-facing space.  It dramatically increased the canopy space of these paw paw and i just reduced that patch, which had already been reduced in numbers once from 8 main trees and 2 smaller ones, to just 5 trees.  There is quite a lot of canopy space for them to fill but i think it will happen quite quickly.  I also played with this paw paw spacing and canopy opening in about five other paw paw patches, which are all wild.  I am curious to see how quick they grow back into a closed canopy as well and wonder when i will have to thin those as well.  Imagine having so many wild paw paws that you have to cut some down.  I consider that an accomplishment.

This upcoming year i will spend more of the growing season there and will be doing heaps of chop and drop and adding in a few more grafted paw paw to get more pollination possibilities going.  They are cross pollinated so this grafted genetics should help since these large patches are often just one tree that has grown rhizominously for years.  One day i will top graft numerous varieties onto these existing wild ones and it will be a paw paw paradise.  I leave you with that image.  Thanks for reading.


Course Recap: 10 day Earthworks and Food Forest. Southern Spain, December 2016

The end of 2016 brought to me an opportunity to lead ten students on a ten day journey of earthworks and food forests. It progressed the students knowledge and skills immensely as well the host site Suryalila Retreat Centre goals. In the end we shaped, mounded, planted, learned, laughed, discussed, debated, and created. More water will infiltrate and when you see a bird land on a tree you planted, well you know you helped to bring life. Enjoy this blog post and an abundant 2017!
