in place in order to control the population of red-imported fire ants throughout the Houston toad distribution range, however they are not being managed. Result A new set of reintroduction techniques have been put into place which as increased egg production. Assisted reproductive techniques such as hormone treatments, biobanking, and in vitro fertilization have been developed by institutions to create optimal genetic diversity and egg development. In addition to this eggs were transported to release sites to give them a higher chance of survival. There has also been an increase in the wild population. Over 450 male toads were heard at the release sites and there were 42 egg strands discovered. There has also been an increase in range, as toads were found 2.5 miles from release sites.
