Houston Toad
An endangered toad survives in scattered sandy woodlands where fire, pond hydroperiod, drought, roads, and soil disturbance determine whether breeding succeeds.

Houston toads spend much of the year concealed in loose sandy soils and emerge to breed in shallow ponds after favorable cool-season or spring rain. Males produce a long high trill. Eggs and tadpoles need water long enough to develop, but ponds with abundant predatory fish are unsuitable.
Habitat loss, fire suppression, drought, severe wildfire, road mortality, disease, and isolated populations drive risk. Recovery includes prescribed fire, pond management, captive propagation, monitoring, and protected land. Listen only from public routes after rain; do not use playback, enter breeding ponds, or publish precise locations.
- Status
- Federally endangered Texas endemic
- Best clue
- High musical trill after warm rains
- Texas habitat
- Sandy pine-oak woodland with seasonal breeding ponds
Quick guide
- Observe
- Drive slowly on rainy nights in known habitat and remain alert for amphibians crossing
- In the field
- Prescribed fire can restore the open ground structure the species needs
Recognize it in the field
- Voice
- Look for a clear, sustained high trill on warm wet breeding nights when identifying Houston Toad.
- Form
- Check small brown toad with irregular dark blotches and warty skin together with prescribed fire can restore the open ground structure the species needs before accepting the identification.
- Ground
- Use Sandy pine-oak woodland with seasonal breeding ponds in deep sandy woodlands of east-central Texas, Texas as habitat context and check the appropriate active season.
- Ethics
- Observe by sound and never enter or illuminate breeding ponds repeatedly.
Good to know
The name does not mean the species is a citywide Houston backyard animal; remaining populations are scattered in specific sandy habitats, especially around Bastrop and east-central Texas. Exact locality protection matters.
