Short Wave

What drives animals to your yard? It's complicated

January 27, 2026

Key Takeaways Copied to clipboard!

  • The increase in lizards and frogs observed by listener Shabnam Khan in her Atlanta-area yard is likely due to local environmental changes that create better wildlife habitat, such as native plants or new water sources, or larger shifts like urbanization displacing wildlife. 
  • Experts suggest two approaches for managing unwanted wildlife: an 'eradication approach' involving making the yard inhospitable (e.g., short grass, no hiding spots), or a 'sharing is caring approach' by creating dedicated sanctuary spots for animals, which benefits the garden by providing natural pest control. 
  • The perceived population explosion of amphibians and reptiles in Metro Atlanta may not reflect an actual increase in numbers, as long-term monitoring data is lacking, highlighting the need for community science programs like MAAMP to gather necessary ecological data. 

Segments

Listener Question Introduction

  • Key Takeaway: Listener Shabnam Khan in Lawrenceville, Georgia, reports a recent explosion in garden visitors, specifically lizards and frogs.
  • Summary: The Short Wave episode addresses a listener question from Shabnam Khan, a long-time resident near Atlanta, who has noticed a significant recent increase in lizards and frogs in her garden. This spike in visitors is causing her stress and prompting the investigation into the cause. The hosts, Emily Kwong and Hannah Chinn, frame this as a ‘Nature Quest’ segment.
Identifying Local Wildlife

  • Key Takeaway: Common native Georgia reptiles and amphibians, such as the Green Anole and Five-lined Skink, are highly adaptable to suburban environments.
  • Summary: To investigate, the host sought identification from Daniel Solenberger, a herpetologist with the Georgia DNR, who identified several species sent by the listener. These identified creatures are common, adaptable species that thrive in neighborhoods and near human structures. The experts confirmed these are native species, not invasive ones.
Habitat Changes Driving Wildlife

  • Key Takeaway: Intentional or unintentional changes in a yard, like reduced mowing or adding water features, can significantly improve habitat quality for amphibians and reptiles.
  • Summary: Experts suggest that changes in Shabnam’s yard or neighborhood over the last few years are likely attracting the animals. Amphibians are particularly drawn to water sources; even a pool a block away can influence local populations. Creating better wildlife habitat, even unintentionally, encourages these common species to congregate.
Managing Wildlife Presence

(00:07:08)
  • Key Takeaway: Managing wildlife involves either making the yard completely inhospitable or creating designated, separate areas for animals to hide.
  • Summary: Two management strategies were presented: the ’eradication approach’ involves eliminating all cover like rock piles and keeping grass extremely short, which negatively impacts other wildlife like birds. The alternative ‘sharing is caring approach’ suggests creating a dedicated amphibian sanctuary in a section of the garden the listener doesn’t actively use.
Urbanization and Ecological Shifts

  • Key Takeaway: Urbanization globally displaces wildlife by taking up natural habitat, forcing species to move into human-populated areas, and fragmentation from roads increases mortality risks.
  • Summary: The trend of increased wildlife sightings is linked to larger ecological shifts occurring in urbanizing areas worldwide, where habitat loss forces animals to relocate. Human development causes habitat fragmentation, which is especially dangerous for amphibians moving between terrestrial and freshwater breeding grounds. Furthermore, human-introduced predators like outdoor cats kill millions of amphibians annually in the US.
Community Science and Data Gaps

(00:12:52)
  • Key Takeaway: Long-term population monitoring data for amphibians and reptiles in Metro Atlanta is scarce, necessitating community science efforts like MAAMP to fill the gap.
  • Summary: Seeing more animals does not definitively prove a population increase; scientists lack long-term data in the Atlanta region to confirm population trends. Mara Dudley is addressing this data gap through the Metro Atlanta Amphibian Monitoring Program (MAAMP). Residents in the area can volunteer, receive training, and contribute documented findings to this monitoring effort.
