Title: Information on what Texas wildflowers are disappearing
Answered by: Nan Hampton


I was shocked to find that Texas Bluebells were vanishing. What other Texas wildflowers are vanishing? There is an endangered species list but I want to help before my wildflower neighbors before they get that scarce.


I guess you are referring to this previous question or perhaps this one.  You mention that you have seen an endangered species list and I suppose it was the one from Texas Parks and Wildlife Department (TPWD), Endangered and Threatened Plants in Texas and the United States.  The TPWD also has another list, A List of the Rare Plants of Texas, by Jackie Poole and Jason Singhurst of Texas Parks and Wildlife Department and William (Bill) Carr of the Texas Nature Conservancy that also includes rare plants that are not yet considered threatened or endangered but are being watched. 

You will note that  Eustoma exaltatum (Texas bluebell) is not on either list.  In a communication about the status of the Texas bluebells with Bill Carr of the Texas Nature Conservancy, he said:

"Those species do fairly well around cattle and even proliferate under certain grazing regimes. Twenty years ago I did an inventory of blackland prairie openings in the Sam Houston National Forest lands in east Texas, and Eustoma was the midsummer dominant in grazed examples. ...Trespass cattle kept everything else grazed to the nubs, but they didn't touch the Eustoma."
