September Stewardship Activities

By Jayne Neal

he vegetation surveys we do are wonderful opportunities to learn how to identify many local plants, get introduced to GPS, and be trained in how to use a compass to navigate in the field. While you do have to be able and willing to hike through brush and in rocky areas, the rewards are indescribable. For instance, finding an uncommon terrestrial orchid, Hexalectris nitida, also known as the Glass Mountain coral root. Curiously enough, while most of the H. nitida orchids that grow on the Edwards Plateau are cleistogamous (selfpollinating) and infrequently have open flowers, those that grow elsewhere in TX have blooms with a “slight sheen that catches the light. Hence the species name nitida, Latin for glossy and polished” (Liggio, J. and A.O. Wild Orchids of Texas). No matter what your particular ecological or natural history interest is, our vegetation surveys are a great opportunity to learn more about local plants and animals, while helping us gather important data. Another great benefit is that we provide all the training and almost all of the equipment. You will need to bring water and a backpack to carry some of the tools we will be providing. In September, we will do our vegetation surveys at Scenic Canyon. Below is the complete schedule of activities. Vegetation Surveys, Scenic Canyon Thurs, Sept 2, 9, 16, 23, 30: 7:30 am -11:30 am. 19011 Scenic Loop Rd., Helotes, TX 78023 Approved for volunteer service hours.

Why Discolored Teeth?

H

By Chris H. Menzel - Alamo Area Master Naturalist ave you ever thought about why rodents have discolored teeth or even noticed? Like most curious things in nature it is a special adaptation that assists in survival. Common rodents include, rats, mice, squirrels, beavers, porcupines, guinea pigs, and beavers to name only a few. Forty percent of mammal species are rodents, and they are found throughout most of the world. Rodents are characterized by two continuously growing incisors in both the upper and lower jaws that must be kept at a constant length by gnawing. Incisors are the frontmost teeth in the mouth. Rodents must have razor sharp incisors to gnaw through wood, break into nuts and seeds, and for defense against predators. The incisors are composed of two different substances, the front (anterior) portion of the tooth is comprised of a high iron content enamel that creates the yellowish-orange tooth color. The iron content is much harder than the rear (posterior) portion of the tooth which is a softer material called dentine. Therefore, as the animals chew, the softer material wears away faster than the colored harder part so that the teeth are constantly sharpened as they grow. So, the next time you see a rodent give a moment of appreciation to how Mother Nature gave this creature a special tool to survive.
