This week's prairie plant features the Compass Plant; this plant is fairly iconic on the tallgrass prairie - a large plant, usually towering above me as I walk through the mid to late summer prairie.  The birds love their seeds and this plant provides a solid platform for many bird nests as well.

I first spread seed for this plant in our first year here at the acreage and five years later we had flowering stalks 5-8 feet high!  It was well worth the wait I'd say, but I'd recommend only seeding for 2-3 years (maybe less) and then wait for the plants to establish, otherwise you'll have stands too thick to navigate!

The leaves on Compass Plants are very distinct and quite large and handsome.  The plant gets it's common name from the leaves tending to orient themselves in a general north-south direction...they are very large, a foot or more in length and half a foot or more wide...very thick and substantial to say the least!

The yellow flowers are 3-4 inches wide and are alternate up the plant's heavy/thick stem.  They attract a great variety of pollinators too!

The Compass Plant's leaves and roots was used by several first nation tribes for many different uses...in the book "Wildflowers of the Tallgrass Prairie" by Roosa and Runkel, it is even mentioned that burning a dried root during a lightning storm acted as a charm to ward off lightning strikes...or hopefully so!
It was also said that when in bloom, a gummy material forms along the upper 3rd of the main stem.  This resinous material was used by Native Americans as a chewing gum.

This is one plant that deer really seem to like in the early summer stage of growth but avoid later on when it gains height...I don't know how good of a forage it may have been to pioneers first settling the prairies but the Roosa/Runkel book says it was liked by cattle as well; likely being a reason it was pretty much eliminated wherever cattle were grazed year after year...I personally have found that cattle are very hard on native forbs, many will not sustain heavy grazing pressure like that year after year.

Next time you're out on the prairie, walk up next to a Compass plant and see how it measures up!  They're pretty cool in my book!

August in the Valley

 It's been a banner year for the Compass Plants, not only here on our pasture, but in many places all over the region.

And even tough it has been a very dry summer once again, the prairie pasture here isn't looking too terribly bad...there are exceptions but the plants are fairly showy this season.

And the Cup plants are looking robust as well - the Goldfinches are drinking from the leaves in the morning dew and soon will be devouring their seed - a favorite of theirs!

Its a mystery to me how summer vanishes before our very eyes.   Oh it hasn't yet by any means, but it just began a blink ago; and here it is August in the valley.

 This morning the sun found me south of the studio two or three miles, walking the "edges" of the Waterman Creek valley.  I had planned on walking the creek, because it is so low that traversing and wading is not a problem right now...we're having another very dry summer here.  

This section of the Waterman is embraced in what I'd describe as a "bowl" or "basin".  I've walked the creek on this section several times but never explored the edges surrounding it.  It was a pleasant surprise when I came upon this small woodland pool on a ridge above the creek.  Some Wood Ducks , likely in molt, paddled towards the opposite side of the pool, softly expressing their displeasure or concern.  The duckweed gave the pool a soft green blanket; a convenient salad breakfast for the "Woodies".

As I had hoped, the air was still as the sun broke; this always helps with closeup landscape photographs like this...leafy branches hold still for a longer shutter speed.

This image is a bit deceiving, as it is mere feet away from the valley opening below,  and this creates a perfect edge habitat for Orioles, Eastern Bluebirds and Field Sparrows.  The Field Sparrows were doing that wonderful trill; its a beautiful song and I was so happy they were still present with their notes!  Soon many of our birds will be in that transition mode into fall and the familiar favorite songs and calls will be absent until returning next spring.  I always regret seeing this transition come.

There are other transitions coming to us here, I won't get into it too much at this moment as I'm going to hold off until I can gather more information.  But it involves a "possible" change for our valley and for our personal lives here.  A very large (it will be the largest in Iowa) transmission line is applying with the state's utility board to run through our property and across the valley past the Waterman Creek Great Blue Heron rookery.  This is a 600kv(+/-) line system to cross the entire state and into Illinois...it will cross 16 counties "if" it is approved, and it will be carried by 200-240 foot lattice work towers.  

We aren't really the masters of our destiny as we so often find out.  And this isn't written in stone yet.  We have joined forces with an association of landowners to do our best to see that this does not happen, and hopefully 16 counties worth of landowners will find a voice to prevent it...but this will be a shadow for a couple years or more before we know what is happening, or not happening.  This has been a unfortunate interruption to the creative flow of work here at the studio, needless to say.  I am now doing my best to direct research and followup time for this specter, to a smaller part of my day, trying to keep things in perspective. I am hoping to stay out of its shadow and into the sunlight so I can still create and enjoy this beautiful gift we have treasured since coming here 11 years ago.

I will write a little more in depth about this soon...in the meantime it is August - grab summer by the collar before it s gone...hope to see you on the Tallgrass!
