Threats/Causes of Endangerment

- -Drought causes loss/reduction in breeding sites
- -High Traffic Roads
- -Red Imported Fire Ants kill young toddlers & also limit their food supply
- -Sensitivity to pollutants e.g. pesticides & organic compounds
Possible Courses of Action for Protection
- -Providing information & education to the general public & landowners of habitat requirements to the toads' lives
- -Protecting pond habitat
- -Conserve management of native vegetation
- -Proper disposal of household, gardening, & agricultural chemicals
- -Special Nongame & Endangered Species are funding for the conservation of habitats to the Houston Toad
