At left, you can see why most people never notice adder’s- tongue at all.
At right, notice the horizontally creeping root system of this fern, and one of its growth nodes We were originally summoned to this site for a plant rescue, as we were told the immediate area was going to become a road and these secretive little plants would be lost. However, before our departure we learned that the development plans had changed and they were in no danger after all. Great news! Since we found that there were thousands of the plants in the area, we were granted permission to remove a small number for relocation in appropriate habitat at LLELA. Currently some have been planted in like soils, while the remainder are growing in the LLELA propagation nursery. One more native plant has found a home at LLELA, as we work to rebuild our ecosystems…sometimes one diminutive species at a time.

Did You Know? Species in the Adder’s-Tongue family (Ophioglossaceae) have the highest chromosome numbers of any known vascular plant species...as high as 600+ pairs. Humans have only 23 pairs.

Friends of LLELA members enjoyed food, fun, and prizes at our 2014 kick-off meeting on a recent cold February evening. A poll taken at the meeting indicated that a majority of members preferred to hold quarterly meetings, so watch for our next gathering in May.
Please plan to attend our “Greenhouse Warming” on March 8 (see below). Although we will be hav- ing chocolate and champagne (or wine) we invite you to dress in your warmest woolies and wellies (boots) and come out to celebrate this wonderful addition to LLELA.
Woolies and Wellies Champagne and Chocolate Tasting Celebrating the Opening of the LLELA Greenhouse And Honoring LLELA Friends, Volunteers & Donors March 8, 2014 • 7 to 9 pm Special Presentation at 8 pm
Put on your warm clothes and wellies and join us at the greenhouse for a beautiful outdoor evening at LLELA! It’s upscale gone back to nature.
For more info or to RSVP: 214.478.1064 or [email protected]
Before the greenhouse warming event, we would like to ask our friends and volunteers to come out and help us spiff up the greenhouse grounds on Saturday, February 15, from 10:00-Noon (there will be coffee & donuts!).
March and April will be busy months for LLELA. Ambassador training will be held on March 19 and 22. This training will equip volunteers with the information and tools they need to spread the word about LLELA as we move into manning booths at local fairs and celebrations and making presenta- tions to various groups.
Please contact Scott Kiester ([email protected]) for more Ambassador information. Scott will an- nounce exact times for training after conferring with our soon-to-be LLELA Ambassadors! On April 26, 2014 LLELA will host the “One Ale of a Trail” Run. Proceeds from this event will ben- efit LLELA operations and programs. This will be a huge fundraiser that will require lots of volun- teers to direct people, hand out water and snacks to runners, etc. The Friends of LLELA will be a key part of the Run’s success.
Please contact Kristy ([email protected]) or Elaine ([email protected]) to volunteer to help that day with the run. Please also let them know of any possible corporate donors you think may be interested in being a sponsor for this event. Generous sponsors will be the key to realizing great success for LLELA.

It’s not easy being green. At an international conference in 1989, scientists all over the world for the first time became alarmed at what appeared to be dramatic declines in some amphibian populations. Then, in 1995, a group of school children in Minnesota were the first to notice an alarming rate of malformed limbs in some frog populations. Because amphibians use wetland habitats during at least part of their life cycle and because they have permeable skin, ecologists believe that declines in amphibian populations and malformations may serve as early warning indicators of broader changes in ecosystems.
Participants in Texas Amphibian Watch have an opportunity to contribute data which can help scientists monitor and understand amphibian populations in our state. Master Naturalist Scott Keister will give a presentation to acquaint volunteers with the monitoring program and frog identification, then take the group onto LLELA’s Bittern Marsh Trail for a bit of on-the-job training.
There is no fee for this program, but we encourage people who attend the training to make a commitment to participate in a new, ongoing amphibian monitoring project at LLELA. In other words...if you show up, we are going to sign you up! Please contact Lisa Cole at 972-219-3930 or [email protected] to register.
