Mark Vander Meer gives a presentation on soil science as it relates to forestry. I was presenting in another room at the same time, so Mark gave permission to Jocelyn Campbell to record this for me. Once I saw it, I thought it was so good, that I asked Mark if it was okay to put it up on YouTube.
Mark is a soil scientist who works as a wild restoration ecologist in Montana. His presentation focuses on soil restoration and is very much question driven.
He starts off by talking about the watershed death spiral, where the soil loses its ability to hold water. Mark identifies three main reasons for that to occur: Compaction, roads, and loss of soil organic matter. He explains that the problem results in streams and springs disappearing.Comments (4)
Building, Energy Systems — by Paul Wheaton February 20, 2013
Four DVDs will be created: "Fire Science", "Sneaky Heat", "Boom Squish" and "Hot Rocket" – showing the most sustainable way to heat.
I pointed the video camera at all the cool stuff at the workshop, just like I said I said I would. Now it is time for you all to pony up for the DVDs. Once funded, the raw footage will be massaged into stuff that will fit into DVD-like thing-a-ma-jigs.Comments (9)

Permaculture is an ethical design science.
– Geoff Lawton
Today I, Paul Wheaton, sat down with Geoff Lawton to discuss all things permaculture in the 195th edition of my podcast. We spent 90 minutes on topics ranging from the issues of being a leader and having detractors to aquifers under the Sahara.
Geoff will be a special guest on the permies.com forums where you can ask him all your detailed, complex questions and get detailed, complex answers in return. Four lucky permies.com members will receive a free edition of his Food Forests DVD.
But most importantly, Geoff says I am right that plants do exchange loads of nitrogen with the soil while they are still alive as Geoff has a meta-review of the review that Helen Atthowe and I did of his Food Forests DVD. He also says Helen was right, but you should focus on the fact that I was right!Comments (4)

Click play to hear the talk!Review of Geoff Lawton's Food Forest DVD, by Paul Wheaton and Helen Atthowe
Paul Wheaton and Helen Atthowe (www.veganicpermaculture.com) watch Geoff Lawton‘s Food Forest video and Helen really loved it. It shows a food forest as they start it, at 6 months, a year, 3 years, 10 years.
Paul thinks it is one of the best permaculture videos. Lawton starts by talking about three concepts: the layering of systems (there are 7-10 layers of a forest), succession of systems (how nature repairs itself), and time (working with different events — eg: sun, shade, flood over time). Paul shares Helen’s hesitancy using the word “permaculture.” They also talk about the word “science” and “studies.” Lawton has 1st, 2nd, and 3rd recovery plants. The first are: annuals, nitrogen fixers, ground covers and leguminous shrubs. The second are medium size nitrogen fixing trees (later to be chopped at head height in order to nurture the longer term trees). The third are longer term nitrogen fixing trees.Comments (1)
