Houston Toad Recovery Plan F 2 Austin Ecological Services Field Office (512) 490-0057 Houston toad Bufo houstonensis 2 1.1 Monitor populations and habitats Ongoing Current FY 2006 Other Management Work type not yet selected Labor type not yet selected 1.1-1 Houston toads were surveyed in 2012 from survey routes. At least 12 positive occurrence points were reported. Most of these points consisted of 1-3 males (with only one chorus over 10 individuals, which occurred over 2 consecutive nights). Houston toad surveys were only conducted in Bastrop County, Texas in 2012. Bastrop County surveys - 28 nocturnal surveys conducted with over 100 males detected over the course of the season (more than what was detected in 2011). Results from daylight searches conducted as a result of FEMA's ongoing restoration work indicated that reproduction at 5 locations within the county were confirmed, with thousands of juvenile Houston toads emerging onto the landscape. At least one pond from within the burn zone resulted in successful emergence of Houston toad juveniles. During 2012, Houston toads were detected well within the Tahitian Village subdivision and just north of the Colovista subdivision for the first time. Dr. Forstner speculates that the 2011 fire did not eliminate Houston toads from the landscape, rather it has appeared to drive the species outside of it's typical boundaries within Bastrop County.

Houston Toad Recovery Plan F 2 Austin Ecological Services Field Office (512) 490-0057 Houston toad Bufo houstonensis 2 1.1 Monitor populations and habitats Ongoing Current FY 2006 Other Management Work type not yet selected Labor type not yet selected 1.1-2 Houston toad populations were conducted in Bastrop County, Texas 2013, although the survey situation was abnormal. The original survey designs retained sites year after year (index sites) as well as a roaming group of survey locations to address construction or other things going on in Bastrop County. From 2010, movement was used to place locations within a conjunction of LPHCP participants to enable feedback and information to those participants. The drought, then fire, meant that the posts did not move from 2011 to 2012. The 2012 route enabled us to provide real-time data to FEMA and the County, but also allowed detection of Houston toads at sites outside the fire zone. There is now a new "normal" for Houston toad surveys in Bastrop county. Dr. Forstner has designed a survey route that emphasizes locations at which recovery operations will occur and may occur during breeding/emergence. These projects are culvert or headwall work that will act to improve the issues of damage and flooding we are seeing across the fire zone. More importantly, repair of the culverts will get the ponding off the roads before those become breeding locations. Dr. Forstner chose to de-emphasize the northern county and eastern zone within the LPHCP boundaries to accommodate detailed information relevant to the recovery operations and understanding toad outcomes in the fire zone. Doing this changes the survey of established historical "index" sites for this year. Email dated January 27, 2013 - "Thus far, we have detected chorusing of Houston toads at two ponds on the night of January 12, a single male was caught crossing the road on January 11, and a second male was caught crossing the road on january 25th. Houston toads are active on the surface within and outside the fire zone, any and all activities that could result in additional mortality are thus now in conflict with that activity season. We did detect reproduction from chorus frogs and leopard frogs in roadside puddles and impoundments, these are a concern but until it is egg strands all this does is enable us to know likely locations for strands to be found." Email March 18,2013 - "We have wild HT and headstart HT calling at the ponds, and being found at the ponds. We had two pairs in amplexus at Pond 12 last night. Weare in excess of 48 Houston toads in Bastrop County thus far this year." Email April 9,2013 - "... we have detected 2 Houston toads in Lavaca County so far. These were N and E of the May 2011 location by a mile or so (2013 points will come after the madness slows). But we have not detected HT in Colorado or Austin counties north of IH10 thus far this year...Bastrop is chugging along, we are above 60 individuals across the entire county (all routes) very few on the Griffith League Ranch, most in Bastrop State Park. We have egg strands head starting and nearing time to go back to the ponds. We also had reproduction at Jim Small this year, eggs in pond. Finally, we had a headstart and wild toad produce a strand in pond 12 which is developing normally."

Houston Toad Recovery Plan F 2 Austin Ecological Services Field Office (512) 490-0057 Houston toad Bufo houstonensis 2 1.1 Monitor populations and habitats Ongoing Current FY 2006 Other Management Work type not yet selected Labor type not yet selected 1.1-3 Houston toad surveys began in Bastrop County in January 2014. Updates from March 2014 chorus survey: minimum 7 distinct chorusing locations have been detected in Robertson County. They are arrayed along N and S of FM 391 east of the junction with FM 2549. This represents the first Houston toad detection in Robertson County since 1976. Chorusing HT males were detected over 100 times in Robertson County in 2014. Surveyers estimated approx. 58 males present in this county. Chorusing HT males were detected in Bastrop County approx. 46 times, leading surveyers to estimate about 20 males in this county. One breeding event (resulting in eggs) was recorded in Bastrop State Park and two breeding events (egg strands) were recorded at the Griffith League Ranch. No HTs were detected from approx. 12 survey nights in Milam and Leon Counties. Only 4 HT individuals were detected in Austin County (north of the Nava property). Only one HT detection was made in Colorado County in 2014, despite 22 survey nights along the Austin/Colorado County route The habitat in Robertson County was described as extremely fire suppressed, so the threat of catastrophic wildfires there is considerable.

Houston Toad Recovery Plan F 2 Austin Ecological Services Field Office (512) 490-0057 Houston toad Bufo houstonensis 2 1.21 Study existing populations and habitats Not Started Other Texas Parks and Wildlife Department, USFWS Regional Office 2, Management Work type not yet selected Labor type not yet selected Should be done as part of 1.1 1.21-1 Research regarding effects of fire on the Houston toad and its ecosystem was completed in response to the high severity Bastrop County Complex Fire, which occurred in September and October 2011. The fire burned 13,406 ha in the Lost Pines ecoregion, much of which was known occupied Houston toad habitat. The goals of the study were: 1) to increase knowledge of fire impacts on amphibians and reptiles, 2) to improve understanding of fire severity as a factor influencing the response of ecosystem components to fire; and 3) to increase understanding of the temporal and spatial ecology, and impacts of fire, on the invasive red imported fire ant (RIFA; Solenopsis invicta), a known threat to the Houston toad. Researchers used low and moderate severity prescribed fire to manipulate the habitat, and incorporated unplanned high severity wildfires into their study designs. The herpetofaunal investigations indicated that direct mortality from fire was not significant, even for high severity wildfires. The high severity wildfire research indicated the post-wildfire landscape provided suitable habitat for herpetofauna about 6 months after the wildfire. The study investigating the influence of fire severity on responses of ecosystem components to fire indicated that fire severity was an important factor, and the influence was related to magnitude, but not direction, of effects. For some components (e.g., pond nutrient levels) the magnitude effect was clear, whereas for others (e.g., species composition of understory vegetation) it was dichotomous in that no effect was apparent for low severity fire and a strong effect was apparent for high severity fire. An additional important finding was mortality of loblolly pine (Pinus taeda) trees was nearly 100% in the high severity wildfire zone, and subsequently loblolly pine tree recruitment was low. Thus, restoration of the Lost Pines will require significant active management through reseeding of loblolly pines, with the alternative being a shift to hardwood-dominated forest patches in the high severity wildfire zone. The RIFA investigations indicated that peak annual RIFA activity coincides with the period when juvenile Houston toads are found at high densities around breeding ponds, and thus are particularly vulnerable to population-level impacts of predation. Further, there was a strong inverse relationship between RIFA captures and overstory canopy cover, and high severity fire appeared to positively affect RIFA through reduction in canopy cover.

Over the following month, the Houston Zoo released over 20,000 Houston toad eggs onto the Griffith League Ranch (owned and managed by the Boy Scouts of America/Captial Area Council) and Bastrop State Park from six egg strands that were propagated from Houston toads in captivity. Students from Texas State University monitored the developing egg strands, and reported successful metamorphosis of the eggs into tadpoles and juvenile toadlets. In late July, over 200 juvenile toads (averaging only 1-2 grams each) were also released onto the same properties.

All eggs are screened for pathogens and other potential health issues by zoo veterinarians before their released into metal hardware cloth exclosures that are used to prevent predation and help headstart the eggs to the tadpole stage of development. After leaving 9 egg strands uncovered (as controls), they were all found to be completely gone (presumably predated on) the day following their release. After the 9th egg strand disappeared, no more controls were used. All other 40 egg strands released were covered. 32 out of the 40 egg strands that were released and covered by the mesh exclosures, were fertilized and experienced some successful hatching - at least in part. We expect the egg exclosures to be very successful in boosting survival of HT eggs in the wild, but we likely won't see evidence of this until the 2016 breeding season (through detection of an increase of chorusing males and reproductive events). Ongoing Current 2014 Labor type not yet selected Work type not yet selected The initial goal to release as many as 250,000 Houston toad eggs during its breeding season in 2014, was not reached due to staffing and space limitations at the Houston Zoo. We will work with the Houston Zoo to help identify other entities interested in Houston toad captive propagation.

In 2014, the Houston Zoo produced approximately 160,000 eggs that were released as tadpoles or juveniles into the wild. The Houston Zoo was also involved in a number of research projects. One involved working with Dogs for Conservation in an attempt to train dogs to detect Houston toads in the wild. They also collaborated with the University of Georgia to develop reliable screening techniques for Chalmydolphila infections in captive Houston toads. Also, zoo veterinarian Dr. Lauren Howard worked to develop effective treatment techniques for Chalmydolphila infections in captive toads. Dallas Zoo – The last of 60 Houston toads that were transferred as part of 3 shipments from the Houston Zoo over the last few years died in 2014. Necropsy and pathology reports indicated that the cause of the losses could not be determined. It is unlikely that any additional Houston toads will be transferred to this facility unless more information is gathered and necessary changes to their program are made. Fort Worth Zoo – As of December 2014, the Houston toad population at this facility consisted of 96 individuals (38 males, 18 females, and 40 unsexed juveniles). This population reproduced on several occasions in 2014 without the use of hormones. They sent 8,150 captive born tadpoles resulting from these reproduction events to the Welsh property in Bastrop County. From July to December 2014, this facility lost approximately 50 percent of their adult population to disease. Reintroduction efforts have been suspended from this facility until these diseases can be managed. Ongoing Current 2014 2015 Labor type not yet selected Work type not yet selected
