Project T-40-R1

Project Title: Utility of Anuran Call-survey Data for Estimating Occupancy, Abundance, and Reproductive Success in the Cache River Basin

Community and/or Species Focus:

 Bird-voiced Treefrog, Crayfish Frog, Wood Frog

Goals/Objectives:
  1. Analyze existing frog calling survey data
  2. Estimate occupancy, abundance, reproductive success, and fine-scale habitat variables at the 10 Cache River wetland sites where call-surveys have been conducted for the past 5 years
  3. Conduct an overall multiple regression analysis on the data collected
Achievements:
  1. ​Routes 1-7 were selected for use based on completeness of data, and GIS was used to map the call sight locations
  2. Surveyed sites weekly using visual, call, minnow​ trap, and dip net surveys
  3. No pattern was discovered within genera for the impact of habitat variables on species; all genera with significant effects had only one member affected

Post-Project Survey (if applicable): n/a
