Butterflies! When we see butterflies flitting from flower to flower, we think about their beauty and how relaxed they make us feel.  What we don’t realize is that they are busily doing a very important job.

Yes we do! Our Natural Area Parks & the Hill Country have very interesting geology with an important relationship with our water source, the Edwards Aquifer. Dr. George Veni provides information on our geology in the series, "Geology of Friedrich Park".

Texas Rat Snake

The recent showers seemed to have stirred up wildlife and given the natural world a resurgence of life it desperately needed.   Rat snakes, including the Great Plains and Texas Rat Snakes, are starting to make their appearance near buildings and out in the field. 

The Texas Rat Snake (Elaphe obsolete lindheimerii) is a common snake that is likely to be encountered in backyards across the area.  This snake can be intimidating by its size, behavior, and appearance.  When agitated or cornered, this snake can move the tip of its tail rapidly in leaf litter or debris to make a rattle-like sound.  Many non-venomous snakes will display this behavior to sound more intimidating.  Of course rat snakes are not venomous and play an important role as predators in a natural ecosystem.

This rare, annual treasure, also known as the bracted twistflower and the bracted jewelflower (Streptanthus bracteatus), remains a mystery in many ways. Read more about this plant in the article by Jayne Neal, The Mystery of the Bracted Twistflower


Mountain Lion

Mountain Lion (also known as puma, cougar and by other names) is a native animal of Bexar County.  They have always been here and continue to survive in reduced numbers.  As our communities expand and wild areas become more rare, these large cats are being forced into areas they would not normally inhabit.

The Natural Areas are nature preserves.  Our goal is to preserve the natural landscape and its native flora and fauna, including mountain lions.  However, human safety comes first.  For your protection we are providing this information.

Please review the Texas Parks and Wildlife's
"Mountain Lions in Texas" for more information and the best reaction for you if you have the rare occurrence of a meeting with this animal.
