Including plant species associated with sage-grouse
Type, Common name, Scientific name

Each species, including the exotic weeds, require a minimum nutrient and organic matter thresholds in the top two inches of soil, for their seedling's survival, as you can see at http://www.ecoseeds.com/good.example.html

No links = Thresholds that still need to be determined, using the Waypoint Lab A-17 soil test plus an A-19-2 organic matter test that are run from the top 2 inches of soil taken from next to seedlings of each species, and the tests run, data only, in a bar graph format.

A second soil sample is taken from bare soil within 10 feet of the first sample, to confirm the threshold levels set by the first soil sample. Each soil sample needs to be a one-quart freezer-ziplock bag full, which has been sifted through a inch mesh screen to remove any rocks or vegetation matter.

Waypoint Lab protocols and the sample form to send in with the soil samples for the A-17 and A-19-2 tests, can be downloaded at http://www.ecoseeds.com/Waypoint-Lab-testing.pdf

FOOTNOTES--

(1 ) - Introduced species.
(2 ) - Especially important sage grouse food species.
(3 ) - Important sage grouse chick food species.
(4 ) - Known Pseudomonas host plants, that produce rain clouds
-- (None so far).
(5 ) - Species not yet tested by Great Basin reseachers,
I am recommending a look.
(6 ) - Known weed-fighting native plant, with strong allelochemical actions.
(7 ) - Cheatgrass thresholds, should be pegged to mature plant heights.


For example, setting the threshold for 2 inch tall cheatgrass plants, 4 inch tall plants, 8 inch tall plant, 12 inch tall plants, 16 inch tall plants, etc.

Then, those soil nutrient and organic matter thresholds that have been pegged to cheatgrass plant heights, could then be used as a rough soil-nutrient indicator. So when you see mature 2 inch tall cheatgrass, you might have very low soil nutrients, that you could confirm with a soil test. Conversely, tall cheatgrass in an area, could indicate richer soil conditions in that area.

Please note--It is unknown which Great Basin species of the following genera have been tested, so for these genera, I have made my own species recommendations for-- Clover, Desert Parlsey, Evening Primrose, Fleabane, Hawksbeard, Lupine, Milkvetch, Mountain dandelion, Phlox, and Wild onions.
