City Nature Challenge – Saturday evening @ Southwest Nature Preserve
Apr 28 @ 4:00 pm – 10:00 pm

Beneath the Water & In the Woods –
See what’s in the pond and look for critters in the Preserve with three experienced naturalists

4:00 pm – The Ponds

Watch as Nic Martinez and friends explore what’s below the ponds using nets and seines (this is an approved SW Nature Preserve activity – please don’t do this on your own). A variety of turtles, frogs, fish, and invertebrates live in the ponds, and we’ll find some of them and document them in the citizen science app “iNaturalist,” as part of the City Nature Challenge 2018.

6:00 pm – The Critters

Take a walk with Michael Smith, Clint King, and Nic as we walk the preserve and learn about this Eastern Cross Timbers ecosystem and the critters that live there. Michael’s and Clint’s specialties include reptiles, amphibians, and invertebrates, but we want to see everything.

 

8:00 pm – After Dark

See and hear the preserve as night falls. We will pay particular attention to the edges of the ponds where frogs may be calling and we might see a harmless snake or two swimming under a nearly full moon. Owls may be calling and spiders will be spinning their beautiful webs.

 

Come with your cameras and curiosity! This place is a treasure trove of beautiful and fascinating life and we want to document as much of it as possible in this year’s citizen-science competition among cities in Texas and beyond. Remember, we take only photos and memories; we do not take anything else home. Children, with a supervising adult, are welcome but please keep in mind that the walks will be an hour or more over uneven terrain. Hope to see you on the 28th.

Program at SWNP: Tree Walk with Jeremy Priest @ Southwest Nature Preserve
May 5 @ 10:00 am – 12:00 pm

During 2018, the Friends of SWNP are offering about half of our programs at the Preserve, with the intent of showing off different aspects of this unique area.  As our second of these on-site programs, we will be walking the trails, looking at trees – identifying the variety of trees at the Preserve with a focus on historic trees.

Jeremy Priest, the City Forester for Arlington, took core and cookie samples from the large post oak “Big Daddy” at the NE corner of the preserve In December. He estimated the tree at a minimum 160 years old just based on his experience with post oaks in Arlington. The samples have been sent for analysis to an arborist in Wylie, working with the Texas Historic Tree Coalition.

Jeremy also cut a cookie from a branch from one of the stunted blackjack oaks on the bluff. After examining the rings, he said the slow growth indicated an age of about 120 years old – even though the trunk diameter was not nearly as large as the big post oaks elsewhere.
