City Nature Challenge 2022 — April 29 to May 2! Mark the calendars! Tell your friends! Engage with nature!

Short message:  The City Nature Challenge is happening again this year on April 29 – May 2!  This event is all about getting the public engaged with nature.  If you’re able, go outside and make some iNaturalist observations, try to host an event, lead some training, or promote the city nature challenge through your platforms. 

Longer message:  City Nature Challenge 2022 is April 29 – May 2!  All iNaturalist observations made within Dallas/Fort Worth (the ten counties that make up the DFW metroplex: Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, Tarrant, and Wise) during this time automatically are added to the City Nature Challenge project

You don’t have to join any project or do any extra steps.  Identification of observations will happen from May 3 – 8.  It will be another global collaboration rather than a competition, but here in Texas, Houston is talking some extreme trash already…  Can DFW let this stand?!?  I think not!  🙂  As a matter of fact, Texas alone has quite a few participating metros. 

If you want to learn a bit more about the City Nature Challenge in general.

If you’re able to host any events — trainings, bioblitzes (virtually or in person), or nature walks, let me know.  We can start collecting these events in a journal post on the project.

So, mark the calendar, tell your friends and the organizations you work with/for, and hopefully you can find some time to spend out in nature.  If you have any questions or concerns, please let me know!

Marine fossils of North Texas and North Sulphur River with Mick Tune — April 6 Wed

Wednesday, April 6

Marine fossils of North Texas and North Sulphur River with Mick Tune

Mick Tune, fossil enthusiast and frequent speaker for the Dallas Paleontology Society, will share his knowledge of the Cretaceous period marine megafossils such as mosasaurs and plesiosaurs from when North Texas was immersed in the Cretaceous Sea, also known as the Western Interior Seaway, This narrow, shallow sea that spanned from what is now the Gulf of Mexico to the Arctic Ocean created the limestone, also called Austin chalk, that forms the bedrock of eastern DFW.

Why is the North Sulphur River’s (NSR) odd and mostly man-made slot canyon the most interesting and open fossil hunting hikes in North Texas? What is its future of it and the Ladonia Fossil Park now that a dam and reservoir under construction will inundate more than half of the river?

Tune enjoys an extended Q&A period, so have your questions ready. Come at 6:30 to see and touch Tune’s 80-million-years old Late Cretaceous marine fossil finds from the Ladonia Fossil Park. Bring your fossils for Tune to try and identify.

Join us at Dallas College Brookhaven Campus, Building H, Room 125. Campus map. See Covid protocol, below. Or participate via Zoom — register here(If you are attending in person, you don’t need to register for Zoom.) 

Tune, who calls fossil hunting “hiking with a purpose,” is the author of Wildering: Anyone’s Guide to Enjoying the American Wilderness and spoke about backpacking at the January 1, 2020 NTMN meeting. Enjoy this GreenSourceDFW feature about Mick, his hiking adventures, and his fossils.

Field Trip:

Saturday April 9, 11 am to as long as you want to stay

Mick Tune will guide us on a fossil-hunting expedition at Ladonia Fossil Park on the North Sulphur River in Fannin County north of Commerce. You just might go home with a shark’s tooth or other marine fossil! Locale is rugged and accessing the river entails a climb. Long pants, gloves and hiking shoes suggested. Be prepared for bright sunlight and insects.

Please note that the park is in a new location due to reservoir construction. New address: 2853 FM 2990, Ladonia, TX 75449. Google maps marker: Ladonia Fossil Park. Internet is not always reliable in rural areas, so be sure to study the map.
