Bring Something for the Raffle Post oak september 2016 2

From the President Jan Miller

As an alternative to these crazy times, marked by goofy weather, uncertain political futures, and looming environmental crises, consider a Nature Rx1 break! According to the calendar and recent weather, fall actually seems to be on the way, so take advantage and visit a local park or contemplate the marvels of your own environs, even if it’s just a potted plant on the balcony. Maybe you had a chance this summer to visit a state park or celebrate the 100th anniversary of the National Park Service, but if not, now’s your chance. Even if you can’t get away, take a virtual trip with Michael Smith’s recent blog post2 on nature’s resilience. The fall season brings new activities, so mark your calendar. Bird migration is underway (don’t miss Charley Amos’ September 7 ACC program) and sightings are increasing already. Monarch butterflies will also be on the move if they aren’t already. And EcoFest3 2016 is set for Saturday, September 17, with new hours: 10 am – 2 pm. Eco-fun for kids, with displays and vendors for adults too. (Tip: Free mulch this year and you can pre-register for free native trees.) ACC once again presents the big Fix-It-Green demonstration, with solutions for saving our natural resources and your $$$. Volunteers will be needed to prep the displays the week before and to greet attendees during EcoFest. It’s a great opportunity to learn more about ACC and great fun, so please join us.

Water Entomology and Streamside Ecology: "Does what you can't see in the water bug you?" by Keira Quam (TPWD) and Mike McCorkhill (FW Fly Fishers and TPWD angler education volunteer)

This program is designed to teach adults how to teach kids about connections between aquatic inver- tebrates and the health of the water. You will learn easy-to-use and effective aquatic species collec- tion, how to determine species types and numbers and what their presence or absence may mean in our nature preserve pond environment. This is a demonstration and applied hands-on class, so expect to use what you learn in our follow-up activities on Saturday.

Water Entomology and Streamside Ecology: Part 2 Saturday, September 24, 9:30 am Southwest Nature Preserve, 5201 Bowman Springs Rd, Arlington

Use what you learned on Tuesday night as we work with a middle school science class in the water at the Preserve. RSVP required! Sign up with Keira at the meeting on Tuesday or email her at [email protected]
