City Nature Challenge 2025, iNaturalist (Ends April 28, 2025)
The weekend of April 25-28, 2025, is when this year’s City Nature Challenge will take place. Participation is simple and easy: spend time in the natural world (something we already love to do!) and document your observations of the species in that area by recording them in the iNaturalist app. Participants often come away from the challenge with a renewed appreciation for biodiversity - and possibly the fragility of the natural world - because of their focused observations.
What began 10 years ago as a friendly competition between just two cities in the USA has become an international citizen scientist event! This year, 690 cities are participating in the challenge, and there is even a Global Project for those who are not in the designated cities. (Observations made in Marble Falls and other nearby communities can count towards the City of Austin’s participation in the Nature Challenge.)
For full details, please see the City Nature Challenge website.

HLBWS Monthly Meeting, “Common Medicinal Herbs in the Texas Hill Country: Cultivating and Wildcrafting”
Invited speaker Stephanie Tourles will discuss six common healing herbs, three that are easy to grow and three that are locally wild-growing. Members will learn the beneficial properties of these herbs and how they can be used medicinally. Samples of the plants in their various forms and products made with them will be available for all to experience.
Stephanie Tourles's education began in the late 1960s -1970s as a little girl on her grandfather's farm in north Georgia. He grew up poor in Appalachia and was well versed in wild-growing herb identification, making home remedies, and Cherokee medicine. He took her for long walks and taught her about the local healing leaves, roots, flowers, barks, and clays, and the art of making salves and tinctures. With much guidance and experimentation, Ms. Tourles began experimenting, mixing up her own remedies and applying them to anyone who would submit to being her patient. She asked for feedback and kept copious notes for years.
Since that time, Ms. Tourles has undertaken extensive study with many herbalists and mentors, training in Western and Ayurvedic herbalism. Between 1994 and 2022, she wrote 15 books on the subjects of natural/herbal skin and body care, topically-applied herbal remedies, insect repellents, raw food nutrition, essential oils for home health, and natural foot care. Her publisher, Storey Publishing, sent her on frequent book tours around the country which included many TV, radio, and bookstore appearances. Currently, Stephanie is in private practice in Marble Falls, Texas, as a licensed massage therapist, certified foot/hand reflexologist, skin care herbalist/licensed esthetician, and craniosacral therapist.
Meeting room doors open at 9:30 a.m. for social time and light refreshments. The business meeting starts at 10:00 a.m., and the presentation begins immediately after the business meeting. Weather permitting, there is a pre-meeting bird walk at 8:00 a.m. at Haley Nelson Park in Burnet.
