Coal Creek

May 29, 2014 I went on a field trip to Coal Creek.  


We have hundreds (if not thousands) of old mines here and this may well be a solution for returning those scarred slopes back to what they once were- alpine meadow and grassland.

No, you probably haven't heard of it but I hope a lot more people will hear about it and we can start this process throughout the Western US.

Here's an overview of the  Coal Basin Project

…. or as  Scott Snelson calls it "the biochar grazing nexus" .  Scott was District Ranger of the White River National Forest at the start of this project.  



Youtube is being uncooperative this morning- so you'll need to click. If you want to read the Aspen Times article on Scott without feeding the marketing machine then go to the link on a tablet or a smart phone. aspentimes.com/article


The group yesterday was impressive. We had representatives from Pitkin County, the Town of Carbondale, The National Forest, the Roaring Fork Conservancy, Roaring Fork Water Shed Plan  and The Crystal River Cattlemen's Association to name a few. Soil Scientists and Geologists who have been monitoring the project were also there. The short version- this represented a lot of cooperation between Federal Government, County Governments (both Pitkin and Garfield), City Government, Private enterprise and non-profit Organizations.  Cooperation and collaboration between agencies and individuals for mutual benefit - what a concept. That may well be the most heartening part of this story.

We met at the Coke Ovens at Redstone.

and we carpooled up the Coal Creek Basin.

Here's Wayne Ives of the White River National Forest giving us an overview at our first stop. 

This was an area which was covered in mining "slag"

much like the Hope Mine on Castle Creek. 



Unlike the Hope Mine this area had traditional grazing on it until about 30 years ago.

So what did the "Coal Basin Restoration Project" do? They used Cattle, Compost, Cattle Stomp and Biochar to restore something which used to look like this:

into something which looks like this

What you're looking at is an acre which has 2 different treatments. Both involve cattle and both involve "seed stomping" one has biochar the other does not.

Here's the process. 

noxious weed control.
a 17th century cure for baldness, dog attacks and hemorrhoids but still a noxious weed.

(Weeds of the West- excellent book)



Then they spread 3" of compost  and then covered it with hay, "White River National Forest seed mix" and straw.

On half the compost had an additional 5% biochar  other than that the process was the same. 

Then came the cattle.

The cattle "stomped" the White River National Forest seed mix in, ate the hay and left the straw for cover (aka "litter). The cattle also left behind fertilizer and hoof prints (I'll get back to that later)

Take a closer look….



You see the distinct change in color in the soil?

That's the biochar.


That's moisture retention.
That's gold.

Compost, Hay, Straw, Seeds and Cattle *without* biochar.

Compost, Hay, Straw, Seeds and Cattle *with* biochar.

Each hoof print creates a microclimate which provides shade and a place for water to pool.


Here's the microclimate without biochar.

Here's the microclimate with biochar.

Got it?

Okay…. up the road a bit… and this time take the cattle out of the process...
Start with what's left over from an avalanche on the road (shale washed down from the cliffs above)
..bring in the machines



to give you some furrows to impede erosion and give the water someplace to settle…

3" of compost with no biochar

in case you were wondering...

 what 1" of compost with biochar will do…

what 3" of compost and biochar will do

There are a lot of elements to this experiment. 

There are plots growing native grasses and forbs under controlled conditions.

(These "bioislands" were planted by Garfield County prison inmates.)




There are sediment monitors on the creek
(There is a lot of sediment in that water- I mean a lot…) 




and soil moisture monitors in the ground.
The tubes go into the ground for control,  non-biochar and biochar compost sections.

Soil moisture monitor at 2", 8" and 20" of depth.

Here's the data- the process doubles the moisture content 

(or more- I'll give you exact figures as soon as I get them).



It's our choice, slag and erosion or



Grass.

Here's more information on the Cattle Stomp and  using the Savory Method to reverse desertification in the links; and here's info on Biochar from Morgan Williams at the 2012 ACES talk (youtube- get your act together please….) click here for the video.
