We Are the Re-Generation


We are not Millennials
We are not Gen-Xers
We are not Baby Boomers, Gen Y, or Z.

We are the Re-generation,

Renewing the soil.
Rebuilding forests, watersheds and wetlands.
Regenerating prairies and lakes.
Redefining farming for perhaps the first time in generations 
and building perennial systems that will support our farm families for generations to come.
We save the soil and we save the farm…we save our place on this planet.

Who else is going to do this?  Cities?  Corporations?
All manufactured landscapes reduce the carrying capacity of our planet.
Show me a value of a street, building, or sidewalk that creates a net gain in the capacity of natural systems. Natural Capital is the real value of a place.
The ecological functions within its natural systems define a sites carrying capacity.

Land and water are the only resources for corrective measures; by raising their carrying capacity. Live in the Biotic World, surround yourself with living things and know the difference. Having us here should be a net gain to the planet and its future inhabitants.

Intensity of Storms Causing Water to be Less Available for Storage.


Two huge rains today, so far. Cats and Dogs, Lamas, Wildebeest. So much at one time we lost way too much to overflow. We increased the size of our downspouts by 33% and still cannot handle the roof run-off. Gutters are fine, Downspouts are adequate. Now the drain tile pipe in the ground is backing up. Overflows at the top. we need to increase the drain tile slope for sure so it drains away faster and possibly a larger diameter pipe. I have been watching this progress for more than ten years. Everything needs to be oversized for the extremes, since the extremes are now the norm. The drain tile backs up three feet above the ground. More slope will create more siphon effect.

BTUs from Tree Species

Fire Wood BTUs by Species
 Its Surprising, the difference between wood species and their output. The efficiency of the stove or fireplace makes a big difference for the actual BTU delivered to the heating system.  Dan

The Energy Content of Wood Species

By September 1, 2015
Method of Calculation: A Cord is defined as a tightly stacked pile of wood with the following dimensions: 4′ x 4′ x 8′. This volume (128 cubic feet) contains an average of 85 cubic feet of wood and 43 cubic feet of air. Each pound of wood contains 8660 BTU’s, but with well-seasoned firewood at 20% moisture, only 6200 BTU’s are available.
Example using Osage Orange: 57 lbs/cu.ft. x 85 (cu.ft./cord) = 4845 (lbs/cord) x 6200 (btu/lb) = 30 (mbtu/cord)

Press Release, PRI/USA Grant Awards 2016











GRANT AWARD

1/28/16 Reno, Nevada.
The Permaculture Research Institute/ USA  awards a $5000.00 URBAN HOMESTEAD GRANT to the Be the Change Project; managed by Katy and Kyle Chandler-Isacksen of Reno, Nevada. The urban homestead is dedicated to permaculture, service, community building, climate and social justice work - particularly at the neighborhood scale.  The heart of THC is the half-acre urban homestead located in a socio-economically diverse part of Reno where Katy and Kyle host classes, workshops, tours and field trips.  The Be the Change urban homestead is electricity, fossil fuel, car-free, and is an example of simple living that highlights permaculture principles in action.
With PRI/USA support, Be the Change will be improving both their urban homestead and the development of an Urban Folk School.  This re-skilling and permaculture learning center will become a food forest, urban intensive garden, and research site for “permanent culture”. The food forest and garden will be powerful hands-on learning tools for neighbors, young urban farmers in training, school groups, Reno’s permaculture guild, City officials/commissions, visitors, etc. The Urban Folk School provides a location for community gathering and organizing toward improving quality of life in the neighborhood and city. The site is also a wonderful public space to demonstrate permaculture’s capacity to take barren urban land and make it a beautiful and productive habitat for neighborhood humans and wildlife alike. 

Funds will be used for;
Food, Plants, and Habitat Development:

  1. food forests and nursery (bare root plants and seeds, mulch, extra compost and amendments)
  2. Intensive gardens (low/mid tunnels, row covers, soil building and planting tools, scale, food cleaning/sharing station, green house shelves/trays)
  3. integrated animal systems (fencing, animal tractor materials)

Drip irrigation materials for food forests, intensive gardens at both sites. seasonal  growing under row covers, and poly tunnels.

Reno Rot Rider Compost System
  1. Bike and trailer parts, bins, buckets, tools
  2. hitch, and hitch connector kits, tires, rims and tubes, hardware
  3. aluminum ladder for a frame, EMT conduit, steel signage and learning/sharing materials

PRI/USA is a non-profit service organization directed by Daniel Halsey, Geoff Lawton, Rhamis Kent, Owen Herbutzel, and Neil Bertrando.
Grants are awarded as beneficiaries apply, show resilient permaculture practices, and demonstrate a commitment to raise awareness of permaculture principles. Grants range from $5000 to $10,000.

How to Use a Standardized Scale for Permaculture Design

In a quest to stream line the design process we use a standard scale for all our work and then resize the artwork for final delivery. That way we always have the same plant symbols available at a common scale and the math is simple too. We are also changing our labeling to clean up the process and add more information. Don't number the plants, "ID" the plants. As always , its a work in progress.

Air Cleaning Polycultures for the Home

Air Cleaning Polycultures for the Home

With growing trends of urbanization and people spending more of their time indoors, the quality of indoor air is an important health consideration. Homes in cold climates reduce airflow as windows close and most apartment builds offer little ventilation. The increased use of synthetic materials over natural fibers and minerals, along with chemicals used in building materials have brought increased volatile organic compounds (VOCs) into the home and work place. These air born VOCs range from carcinogens like formaldehyde to petrochemicals like benzene and xylene. This is added to more familiar household chemicals such as alcohols and ammonia. Obvious sources like paints and adhesives combine with subtle sources like grocery bags, cosmetics, paper towels, and upholstery. All emit this wide range of chemicals into our indoor spaces and the air we breath.
As building practices better seal buildings from outdoor air, we are also creating the problem of trapping these air born chemicals indoors. When The National Aeronautics and Space Administration (NASA) began researching how to maintain a healthy indoor environment for astronauts traveling to the moon (which is an excellent extreme example of our indoor air problems, they needed to address high amounts of chemical emissions and with no possibility of outdoor air exchange) they quickly realized that the best air and water filters were not products of their own engineering, but from nature: plants.
A series of studies conducted by NASA and Wolverton Environmental Services, Inc. assessed the air-cleaning properties of a wide range of common indoor plants, identifying their varying capacities for chemical removal.  Subsequent studies have also found microorganisms in the potting substrate important contributors to emission absorption. The collection of plants that have been identified as air-cleaning species can grow in a large range of  indoor environments. Furthermore, their use is not limited to air cleaning potential; for all of these plants can contribute additional functions to our indoor spaces whether it be ornamental, medicinal, or edible. Taking into consideration the unique micro-climates and need of your home, you can build your own efficient air filtration system with a polyculture of air cleaning plants. The Natural Capital Pant Database has documented these plants to help subscribers build their own air cleaning polycultures for indoor use. 

Two polycultures for indoor air cleaning
Indoor air-cleaning polyculture 1:
  1. -Golden Pothos (Epipremnum aureum) 
  2. -Sword Fern/Boston Fern (Nephrolepis exaltata)
  3. -Areca Palm (Chrysalidocarpus lutescens)
  4. -Lady Palm (Rhapis excelsa)
  5. -Peace Lily (Spathiphyllum)
  6. -Australian Sword Fern/Kimberley Queen(Nephrolepis obliterata)
Features: Best in part to full shade and high humidity, have high transpiration rates, sensitive to cold temperatures, all grown for their foliage with the exception of the peace lily (which has a white spathe/spadix structure).
Chemicals removed: Formaldehyde, benzene, trichloroethylene, acetone, toluene, xylene, ammonia, alcohols, carbon monoxide.

Indoor air-cleaning polyculture 2:
  1. -Gerbera Daisy (Gerbera jamesonii)
  2. -Chrysanthemum (Chrysanthemum morifolium)
  3. -Ficus Alii (Ficus macleilandii 'Alii')
  4. -Pygmy Date Palm (Phoenix roebelenii)
  5. -Aloe (Aloe vera)

Features: Best in full sun to part sun, low humidity requirements, med-high temperature requirements, high insect resistance, very ornamental plants with varying textures and colors. 
Chemicals removed: Formaldehyde, benzene, trichloroethylene, toluene, xylene, ammonia

Blocks of Change

So many issues with change. We are baling Sand Love Grass for soil OM in the red sandy soils of West Texas. Two balers have tapped out, saying the ground is too rough. An ecologist said we should burn and/or disk the entire 160 acres of bumpy sparse grass land, while I see the plowed cotton fields blowing away nearby. Grazing is expensive if you want paddocks, otherwise cattle ranchers are happy to let the cattle in and eat it to nothing.

With tufts of grass far apart. what is the low calorie solution. Scything seems too energy costly. Long term, we need OM, ground cover, wind abatement. All on 6 - 12 annual inches of rain. No key-lining or sub-soiling needed.  For now we are focusing on the zone 1 homestead, hoop houses, berms, and plants. The field will wait.

Slugs Occupy Vermicomposting Farm. Good, Bad, Ugly? Depends.

In seeing the slugs in the worm boxes at American University in Beirut,  I thought I would investigate whether they are carnivorous. Some are. Its good to familiarize ourselves with co-occupants in the worm ecology. I wonder if they eat the worm eggs.

Testacella haliotidea Draparnaud

A Leopard Slug is omnivorous, eating other small slugs. But mostly eats fungus and OM.
Leopard slugs are know vectors of meningitis (just don’t eat them raw).    This photo is from the AUB worm farm.
Probably not an issue and not a plant eater.






Worm-Eating Slugs Family Testacellidae

Fauna of Soil Ecology
This carnivorous semi-slug  spends most of its time underground, where it   hunts and consumes earthworms, snails and slugs . The shelled  slug  is commonly   found in disturbed habitats like gardens, parks and agricultural fields.   This slug  is able to burrow to depths of up to one meter during periods of   aestivation. This animal has not been reported to feed on plant material and as such should not pose a threat to agricultural produce.  The ecological impact that this species may have on other terrestrial   mollusc  species has not been documented.

http://tcpermaculture.com/site/2013/05/24/predatory-gastropods-aka-carnivorous-snails-and-slugs/

Worm-Eating Slugs (Testacella species, Family Testacellidae): Found in Europe, Africa,  Britain, and Islands in the North Atlantic. These slugs with a shell (yeah, they are still called slugs, not snails) primarily eat earthworms and live most their lives underground. There are some reports of these slugs eating insect larvae as well.
Ghost Slug (Selenochlamys ysbryda, Family Trigonochlamydidae): Found in the UK and Europe down to Turkey. Also a earthworm eater.

What is our ecological function on the Earth?

Through research and investigation every plant and animal on the earth has been categorized for its characteristics and ecological functions. Every animal except human beings. What is the ecological function of mankind on the Earth?

Having studied and designed agricultural ecosystems as well as sustainable homesteads, I have come to the conclusion that the ecological function of mankind is to raise the carrying capacity of our planet. We can by good design and good decisions actually increase the availability of food, clean water, clean air, and the resources for a comfortable lifestyle.

On my own homestead and on those I have designed it is obvious that it does not take much effort to create a self sustaining and resilient food production system. It is a system that over-yields and can feed many more people than those occupying the land. It is also a system that feeds all the plants and organisms that support it. The principles of permaculture, holistic management, and a restorative culture make possible the vision to create a new future where everybody gets fed.

First Year Wintering Livestock, Goats for Now

When you enter permaculture and begin listening to the land, you soon learn to sense the site conditions as they change, sometimes before. Each season fine tunes our perception to deeper detail. It wasn't until I owned and tended livestock that I truly felt the harmonics of change.

The sensory connection to the land is immediate upon the implementation of a design or planting space. The connection with a living creature, especially one as intelligent as horses, goats or pigs brings a whole new level of understanding. Watching the thermometer, wind, and humidity brings a realization that something else is out there enduring the conditions that would otherwise make quick history of ourselves.

Beneficial Habitat: Beetle Banks




Ground Beetle
Large expanses and widening fields for crop production have substantially limited the access of beneficial insects to field crop prey. The ecological services provided by naturally occurring pest predators is increasingly impeded spatially as the fields grow. The field edges, being the over-wintering and refuge for beneficial insects, are the primary source of conservation pest management in many crops. As much as 35% of pest management and crop protection comes from naturally occurring biological controls. Increasing the natural capital needed to enhance the supportive habitat is a low investment and a high return strategy for growers. 

This technique is also important in the ecological design of food production areas on homestead or in a production orchard. Many times we think of beneficial habitat for the use of pollinators and flying insects. We need to remember that there is a great diversity of beneficial insects that need habitat. Beetles play an important role in controlling past populations in our growing spaces.

Beetle Banks, suggested by Southerton (1984) are grassy ridges within crop fields, which by their position, decrease the travel distance of flying or crawling beneficial insects. Field edges of rough Tussock grass covered banks (Luff 1966) support a high density population of Caribidae ( Large Ground Beetles) and Staphylinidae (Smaller Rove Beetles) (Thomas 1991).   
Rove Beetle
Reducing the distance from edge to edge increased the frequency and duration of insects in the center areas of the fields. Especially in Spring, as the insects migrate further into the field following aphid and other pest populations. Although Collins, et al (2002) refers to it as decreasing field size, I believe the banks are an integral part of the field itself and a permanent fixture within the cropping system. The control of cereal aphids has been the motivation for many of the studies to be cited. Polyphagous arthropods are important players in the natural biocontrol of wheat pests. Conservation Biocontrols are the  " ..techniques to encourage and conserve populations of naturally occurring (pest) predators..." (Collins et al, 2003).
According to Collins et al. (2003), the most needed Integrated Crop Management (ICM) component is natural biocontrol agents (BCA).  The most important BCAs in Cereal aphid control are polyphagous (predators of multiple prey, not specific) arthropods. Since expanded agricultural intensification has removed or degraded field boundary areas, added habitat spaces are needed for increased polyphagous predator benefit.






Field edges of rough Tussock grass covered banks (Luff 1966) support a high density population of Caribidae and Staphylinidae (Thomas 1991).  Beetle Banks, suggested by Southerton (1984) are grassy ridges within crop fields, which by their position, decrease the travel distance of  beneficial insects, flying or crawling. Reducing the distance from edge to edge increases the frequency and duration of beneficial insects in the central areas of the growing space. 
Function of Beetle Banks
The function of the beetle banks is to increase supportive habitat for conservation biocontrol, reduce stress on predators of crop pests, and the travel time from over wintering habitat to field center.  The over-wintering refuges (Beetle banks) are placed mid field and allowed to regenerate foliage from seed and natural sources. Colonization by local plant, animal, and insect genera may take time to disperse from existing habitat.  Transfers from previous spaces are affected by soil, distance and quality of field margins, and insecticide used in field areas. Generally, banks are seeded and left to natural species movement (Collins et al. 2003).  From all studies reviewed, none inoculated the beetle banks with field margin soils or plants. Barren strips were seeded and started without the trophic system existing in the unplowed habitat of field edges. Using the comparison of the field margins as the banks mature gives a good baseline for the progress of the monitored insects. In practice it may be better to transplant dormant grasses and soils from the margins into the banks to inoculate and accelerate the banks succession

 
Key design considerations

Provide plant diversity and structure in the buffer.

Protect buffer from disturbances (e.g., pesticides, tillage).

Predation of insect pests generally increases with the percentage of buffer habitat in the area.

US Forest Service 1400 Independence Ave., SW
Washington, D.C. 20250-0003
Locate buffers throughout the fields and landscape to encourage dispersal of beneficial insects.

Buffers may provide habitat for some pest insects but this can be reduced by selecting appropriate plants Beetle banks are long, planted berms that provide habitat for beneficial insects.
 

The Goal

  1. The manipulated habitat increases the population of beneficial insects
  2. Beneficial arthropods move from the enhanced habitat to have an area of agricultural value
  3. The beneficial arthropods established and/or remain in growing space long enough to provide an significant impact on the pests for increased harvest              (from Loughner R. et al, 2010)

Do beetle banks do this?

Can the habitat enrichment increase PCs enrichment and the supporting trophic levels to sustain an ecological and best economic benefit?

Design and Installation

•With farm equipment, the bank is created by careful two-direction plowing, with furrows plowed against each other, during autumn cultivation.
•Machine drill or hand sow with a mixture of perennial grasses including at least 30% tussock-and mat-forming species (in the UK, these include orchard grass (Dactylisglomerata) and Timothy grass). •The rest of the mixture can consist of fescues and bents.
•For good establishment these can be sown at a rate of 70 kg/ha (62 lbs./acre).
•Three mowing cuts may be necessary in the first year (when the sward reaches 10cm) to encourage grasses to tiller and control invasive annual weeds.
•Once established, cuts are needed only to encourage dead tussocks to regenerate, and to control woody species (approx. once in three years).

Permaculture and Polyculture Consulting and Design

Permaculture and Polyculture Consulting and Design
Getting to know your property, the plants you have and those you can grow, is a fulfilling endeavor. With most I am the steward of the land. I give them good soil biology and they do the rest. If I group them in cohesive plant communities, they respond with greater yields. If I encourage the micro-organisms (Fungus and bacteria) , the roots obsorb more nutrients making a pest and disease resistant plant. A stronger plant that gives us more organic food and takes less energy.
