Over the years, the soil underneath my back deck has been a home to ground-dwelling bees, a rat or two, and a skunk. I don’t mind the wildlife, especially the skunk, who is a good neighbour (aside from eating my water lilies). Dirt is a living expanse, it’s not supposed to be sterile.
This week, I did some deck reconfiguration as I was changing the set up of this year’s garden. As I lifted various parts of the deck, I noticed the soil was quite moist and rich, sheltered from the heat, and it had been tunnelled, turned and fertilized by rodentia and others. (Tip for dealing with the skunk’s latrine: throw down some dolomite lime).
I took a course in Organic Soil Fertilization late last year and learned that my soil type is loamy clay. I also learned that soil microfauna, like isopod “pill bugs,” centipedes, and worms, are essential for soil fertility as they are our little decomposer friends, grazing on bacteria, fungus, carbon sources, and occasionally each other. Soil macrofauna, like rodents, amphibians, and others who burrow to make nests and passageways, are considered soil engineers. They are particularly responsible for distribution of seeds and nutrients.
I’ve since found a chapter, published in two different books on ecological management of rodents as pests (and not as pets as we know them over at Mooshika). The chapter Rodent-Ecosystem Relationships discusses the positive aspects of rodents in ecosystems. This perspective is long overdue, considering how we belabour beyond any context the economic damage they can do to crops and the public health issue of plague, which isn’t that relevant over the past 100 years. Let’s hope it’ll take about a quarter as long to put those issues into their proper perspective.
I would like to hope that we could be free of scapegoating rats and mice or any other creature, but really, we must try to see them as they actually are. The above book chapter is a welcome addition to the literature. It is by Dr. Chris Dickman, an Australian desert ecologist, of whom you can see on ABC Television here: http://www.abc.net.au/catalyst/stories/3251977.htm
