On February 3rd I presented the results of a study involving patch burn grazing on a prairie natural area. For those interested, here is a link to a PDF that I generated from the Powerpoint slides and my notes. Feel free to post any questions or comments here.

    Great presentation, with very clear arguments. It is interesting to see the comparisons.

    Thanks for sharing! Are there any control transects?

      Great question. There are control transects on a nearby prairie that have been sampled eight times over the past 17 years. Richness and diversity on these transects fluctuate from year to year while mean C-value stays relatively constant around 4.50. The two years of baseline data also serve as controls. This study is currently being polished for submission to a peer reviewed journal.

    It begs the question about timing and intensity of both burns and grazing - do you have any of those details?

      I have some details. Burning was always before early March with low to moderate intensity. Grazing was moderately high to high intensity from early June to late August (three months). I have the pounds/acre written in my notes. I could look it up if you like.

Strolling the Remnants: Sand Prairie Conservation Area

Image
My work through the Institute of Botanical Training takes me all over the Midwest. In 2009, I was working on a contract in southeastern Missouri that was about an hour from Sand Prairie Conservation Area. An admirer of prairies of all kinds, I visited the site twice over the season and would like to share my observations below. Visit One: April 17: A chilling spring breeze blows across the sand prairie. Sun-warmed sand dislodges, rolls and re-accumulates as it gradually exposes and conceals scattered pebbles in this sandy scene. Small dune-like hills stabilized by vegetation subtly gradate into expansive flats. The surrounding landscape speaks of the early Holocene winds and braided waters of glacial outwash that are responsible for the sandy deposition. A sprinkling of sand islands scattered within a matrix of wet forests of the Mississippi floodplain. Here, inches in elevation separate desert from swamp. Weathered gray stems spinning in the wind draw solar systems in the sand. The

A Spring Prairie Tour

A Spring Prairie Tour (May 1, 2020) by Justin Thomas Director of Science NatureCITE The following photos have been posted for folks listening to the NatureCITE podcast #5 (link  here ) to follow along with. For more about ecological emergence, ascendance and autocatalysis see NatureCITE podcast #3 and stay tuned. The photos aren't great, but by using the captions of each photo while listening to the descriptions on the podcast one should be able to better understand of the phenomena and lifeforms explained in the podcast.  Castilleja coccinea (Indian Paintbrush). This was the only population seen on the property, though it used to be common. Growing season fire (that which occurs from mid-February through late September), especially in the spring, burns up the rosettes of this species before they can grow and flower.

Botany Road Trip: Spring 2008

Image
Every spring I like to take a botanical road trip. Last spring my buddy Brad from Michigan came down and we took a southern tour. Due to a computer malfunction, I was unable to show my slides of the trip at the annual Botany Slide Show Extravaganza this winter. So, being compelled to salvage the usefulness of my slides from the trip, I put together the following. The trip started right here in Dent County with a visit to Big Glade at Indian Trails State Forest. Big Glade had received a solid burn earlier in the spring. The tender green tips of summer grasses and sedges were just breaking dormancy and lending a green buzz to the chert strewn dolomite shelves of this spectacular natural area. As it was early yet, few plants were flowering. Here are two fun ones: Castilleja coccinea (yellow form) is one of my favorites. This hemiparasite is common on glades, but rarely abundant. This is Silene caroliniana var. wherryi . In Missouri, it is only known from a cluster of counties in the ce
