This research study focuses on 31 families (n = 105 individuals) and their experience using a place-based e-Trailguide to observe and learn about the local biodiversity during a hike. Open-ended interviews were conducted with each family after their hike with the e-Trailguide to assess shifts in biodiversity awareness. 190 interview responses were thematically coded into 17 different categories. Results showed that new awareness of tree characteristics, plant identification, and insect species were reported most often. Overall, families' new awareness of plants was reported more than animals. Implications highlight the value of place-based and temporal-specific content when designing outdoor-based mobile programs for families.
