February’s heavy snowfall and long-lasting freezing temperatures affected many fish and wildlife species throughout Texas. In a state this large, you can help Texas Parks and Wildlife Department biologists assess the damage by reporting any animal mortality events you see on your property or neighborhood through a special project on the iNaturalist app/website. 

The prolonged period of subfreezing temperatures, coupled with a limited availability of food resources due to snow and ice, has had some impact on wildlife resources; however, given the secretive nature of most wildlife species, the full extent of the impact cannot yet be determined. Some of the wildlife species impacted by the storm include exotic, non-native ungulates like axis deer, blackbuck and nilgai antelope that originate in temperate climates, various bat species and multiple bird species.

Did our native and exotic deer make it through the storm?

While TPWD has no regulatory authority of exotic species, the cold weather did have a significant impact on some. White-tailed and mule deer are much more tolerant of these extreme cold weather events than exotics, so TPWD doesn’t expect significant losses of our natives, except a few very old whitetails.

Despite potential significant loss of axis and blackbuck, this mortality event may lower free-ranging exotic populations in areas of the Texas Hill Country where they were overpopulated, ultimately helping native habitats that benefit white-tailed deer and other wildlife.

What about deer habitat? Is there food for them to eat?

At this time, the more pressing concern is possible impacts the cold weather had on the native deer habitat in some regions. In South Texas, some brush species still had green leaves prior to the freeze and snowfall. Now, however, TPWD staff are noticing many shrubs shedding leaves and turning brown.  Additionally, the winter herbaceous vegetation, which are critical for deer this time of year and into the early spring, were impacted and burned by the freezing temperatures. TPWD is hopeful that, despite the cold temperatures, the moisture from the snow and ice was able to be absorbed by the soil and as temperatures warm up, the usual spring green-up will take place statewide.

Don’t handle impacted bats!

Across the state, citizens, biologists and park employees are reporting dead bats under bridges, along with finding live bats that were downed due to the freeze because of dehydration, starvation, and cold body temperatures. Currently, wildlife rehabilitators and other organizations are being inundated with the bats that survived the storm and doing everything they can to help.

If you find dead or live bats, it’s extremely important not to handle them. The best course of action is to record the observation via iNaturalist and then, if the downed bat is still alive, contact a rehabilitator. A list of wildlife rehabilitators can be found on the TPWD website as well as on the Bat World Sanctuary website.

How are birds faring? They looked so cold and hungry.

TPWD staff continue to receive reports of dead birds, including waterfowl. Biologists have received reports of dead songbirds and woodpeckers, possibly resulting from poor body condition and lack of cover from ongoing drought conditions in certain habitats. Insectivorous and nectivorous bird species likely suffered greater losses than other bird species. Quail, however, fared well according to some reports. Richland Creek Wildlife Management Area (WMA), among other WMAs with wetland ecosystems, reported hundreds of dead coots and multiple dead Blue-winged Teal.

What about the fish kills along the coast?

We’re continuing to assess fish kills along the coast. Here’s what we know so far. 

I found an injured animal, what should I do?

Please contact your local wildlife rehabilitator. See our website for tips on how to assess the situation, including a link to find licensed rehabilitators by county.

Did Texas Fish Weather the Snowmageddon?

February’s massive winter storm impacted not only the millions of Texans who lost power and water — long periods of frigid temperatures caused problems for the state’s fish population as well.

Texas Parks and Wildlife Department biologists are assessing fish kills, a process that can take some time in a huge state with a lot of coastline, but they’ve released some preliminary observations of the trends they’re seeing. As they amass more information, they’ll know more about the extent of the mortality. It’s a bit like putting together the crime scene to solve the mystery.

You can help them! TPWD is asking for the public’s help in reporting any animal mortality events they observe on their property, ranches or in their neighborhoods through a special project on the iNaturalist website or app. It’s easy to download your photo or enter a quick bit of information on what you saw and where. That’s all you have to do!

Fortunately, the winter storm’s impacts to inland freshwater fisheries have likely been minimal, especially when compared to observations along the coast. There have been a few reports of threadfin shad kills in North Texas as well as non-native tilapia kills in the far southern region of the state, but no impacts to freshwater sport fishes have been documented. Rainbow trout stockings planned for that week of arctic weather were postponed to wait for improved travel conditions for delivery.

Freezing events along the Texas Coast are rare, but extreme cold temperatures can be a natural cause of fish kills. If fish do not make it to refuge in deeper, more temperature stable water in cold weather, they may die when water temperatures reach a certain threshold. For example, spotted seatrout experience more mortalities associated with freezing weather than other common game species.

Currently, TPWD is seeing localized fish kills in affected bay systems and receiving reports of areas with dead fish from guides, anglers, and other boaters along the coast. Initial reporting of fish mortality occurred February 14; the work is ongoing. Rapid assessments indicate the majority of fish (by number) impacted were non-recreational species including pinfish, spot, silver perch, gulf menhaden, mullet and other foraging fish. Recreational species impacted include spotted seatrout, red drum, sheepshead, grey snapper, snook, black drum and tarpon.

The geographic extent of fish kills includes the entire Texas coast, but bay systems south of Galveston Bay have seen the biggest impacts. The majority of the kills were located along the southern shores and undeveloped areas, such as the back sides of the barrier islands. Affected recreational fish include spotted seatrout, red drum, black drum, sheepshead, grey snapper, snook and tarpon. 


Sabine Lake 

  • Reports of a fish kill in Keith Lake system of Sabine Lake. Game wardens reported seeing red and black drum, in addition to some sheepshead. 

Galveston Bay Area

  • Fish kills reported over a 3-5 mile stretch in the Gulf Intracoastal Waterway (GIWW) near Christmas Bay, a 9 mile stretch of the GIWW from Swan Lake to Bastrop Bay. Minimal impact with species observed included mullet, sheepshead, small spotted seatrout and red drum.  
  • Fish kill observed in a dead-end canal system in Village of Tiki Island and Jamaica Beach. TPWD observed numerous dead mullet floating and a number of other unidentified fish on the bottom of the canal. TPWD retrieved several fish off the bottom from Jamaica Beach with nets. All fish recovered were mullet.  
  • TPWD surveyed areas of Christmas Bay and Cold Pass approximately 2.5 miles and observed no dead fish.

Matagorda Bay

  • Fish kills in Carancahua Bay, East Matagorda Bay, Magnolia Beach, Matagorda Peninsula, southern shoreline of the GIWW to West Matagorda Bay, Turtle Bay, Port O’Connor public beach and pier, canals at Sargent, Keller Bay, Lavaca Bay. Multiple species observed.  

San Antonio Bay

  • Fish kills observed at the Matagorda Island shoreline, Pringle Lake, southern shoreline of San Antonio Bay. Pringle Lake was hit especially hard with a larger proportion of game fish observed. 

Aransas Bay

  • Fish kills observed throughout Aransas Bay system including Lighthouse Lakes kayak launch, Hwy 361, Airport Park Point south to Copano Village, Copano Causeway, Bahia Bay canals, Camp Aranzazu, Ransom Channel boat ramp, GIWW adjacent to Redfish Bay, Mud Island, Cedar Bayou, and southern shores of Mesquite Bay. Multiple species observed.

  • Fish kills observed in Padres Island canals, shoreline near Clem’s and Billings boat ramps, shorelines in Lake Padre, Upper Laguna Madre near JFK causeway, canals of North Padre and Tropic Isles, Land Cut, and Baffin Bay. Multiple species observed with areas particularly hit hard being the Land Cut area. 

Lower Laguna Madre 

  • Fish kills observed in Port Mansfield area, Arroyo Colorado, Brownsville ship channel, Long Island commonly known as the “Y”. Multiple species observed.  


Coastal Fisheries biologists will continue to make on water assessments into the week of Feb. 22-26.  While ongoing assessments can provide some estimates of the magnitude of this event, biologists will be able to present a more accurate assessment of the impacts on particular species as routine monitoring (gill nets, bay trawls, and bag seines) continues and they are able to benchmark numbers against sampling efforts from previous years.  

For many of the key game species, informative data will start coming in with spring gill net sampling which runs from mid-April thru June. Additionally, as a part of year-round survey efforts, biologist will soon begin collecting information from recreational anglers at boat ramps.  

This data will provide additional information regarding the impacts of this cold-weather event and will help inform what management actions, if any, are needed to help accelerate recovery of fish stocks.
