Keyline Treatment of Headcuts

A central concept of Keyline-pattern subsoiling is plowing downwards in valley-forms and upwards on ridge-forms.  This discussion between Chris Gill and Ken Yeomans explains why.

Doing What Works: Range Magazine

Here is the summary of two years of correspondence with the Mule Deer Working Group, my futile attempt to get them to change the sloppy-science-based range advice which so harms desert habitats and wildlife. What this shows with respect to the range science on which wildlife practices are based, is 20 wildlife agencies  ignoring science

Habitat Guidelines for Mule Deer

This document was amended in 2009. It is dated 2006, but contains, for example, references to the Briske, et al. paper published in 2008. Its conclusions are identical to the unamended version.

Richard Teague et al. on Benefits of Planned Grazing

This paper by Richard Teague, Fred Provenza et al. challenges the conclusions of Dr. Briske.

Keyline Concepts for Subsoiling

Netting out what comes below, as explained in paragraphs 11-18: always plow valleys downwards and ridges upwards. This is the heart of Keyline subsoiling and the major unrecognized aspect of contouring which can actually cause erosion to increase.   Next is the plow itself. Virtually all plows and discs are designed to kill plants and

Chris Gill to Dr. David Briske

I had already read the Briske paper and realized that it tested Short Duration Grazing systems and not planned grazing. But when the Authors of Habitat Guidelines for Mule Deeroffered it as proof of their conclusions against planned grazing, I wrote Dr. Briske this letter and copied the Authors.

Chris Gill's Response to the Mule Deer Working Group Regarding Habitat Guidelines for Mule Deer Advice Against Planned Grazing

Rather than send a long, separate response, I decided to try an  interlined response, dealing with these points one at a time.  I hoped that doing it this way would get the authors to focus point-by-point.

Of Mule Deer and Paradigms

I wrote this for Holistic Management International’s semi-monthly publication In Practice, discussing the Mule Deer Working Group’s unwillingness to amend its conclusions which misstated the scientific basis for their advice against planned grazing.
