Brackenridge Field Lab- Creek Corridor

The video begins in the middle of a stream that runs through the NW portion of the field station, approaching a limestone seep that creates a large pool housing a number of rare species of frogs and salamanders. The video continues up a trail and downstream to a large 400+ year old pecan tree. During a devastating flood caused by a catastrophic dam failure in 1900, the tree was buried at least 30 feet in silt. subsequent erosion has removed some of the silt, but the tree remains buried in over 15 feet of silt. The tree has survived and still produces a yearly crop of pecans. Viewing Tips: After starting the video, click on the gear icon “⚙️” in the lower right corner of your screen. Set video quality to 1080 (HD) or higher, adjust playback speed, or turn on closed-captions. The Virtual Field's Ecosystem Exploration Series allows viewers to develop their own powers of observation by studying the environments of the earth. Each 5-min video is filmed by staff or researchers at field stations and marine laboratories around the globe and comes with an accompanying video guide. The guide helps instructors teach students to observe evidence of concepts they learn in class. Concepts are tied to the ESA's Four-Dimensional Ecological Education framework, formative processes and adaptation. Video guides provide questions that encourage students to look for specific kinds of evidence in the video and document their answers with descriptions, drawings, or digital media. Annotated versions of the video and video guides provide details linking evidence to concepts. For more details, see instructor guide (https://docs.google.com/document/d/15...) or visit https://thevirtualfield.org/. The Virtual Field is a coalition of 50+ field stations and marine laboratories around the globe creating a suite of virtual teaching materials that introduce students to field research and observation. Projects are funded by a grant from the National Science Foundation and is a collaborative project of the Organization of Biological Field Stations.
