Dam construction update: starting on June 1, LLELA visitors will not be able to cross the outlet works. There will be no access to the Bittern Marsh Trail or east side of the river. Sometime soon (date currently unknown), all access east of the Cicada Pavilion will be prohibited for about 8 weeks. This will include the following areas and trails: Bittern Marsh Trail, kayaking and fishing in the Elm Fork of the Trinity River, all camping areas, and the Redbud Trail. Only the Blackjack, Green Dragon, Cottonwood, and Cicada Trails will be open during that time.


Wintering Ecology and Migration Tracking of Kestrels


Kelsey Biles-kestrelsUNT doctoral student Kelsey Biles conducted research on wintering American Kestrels in Denton County, including birds at LLELA. Kestrel populations have been in decline, and while researchers believed the cause of the decline was occurring on the birds' wintering grounds (including in Texas), little research had been done on the subject. Biles' study asked three questions:

  • What factors are related to kestrel survival within and between winter seasons and site fidelity in North Texas?
  • Which of the two most common methods (leg-loop and backpack harnesses) is most effective for attaching migration tracking devices to American Kestrels?
  • What are the potential benefits of pairing behavior exhibited by American Kestrels during the winter in North Texas?
