Summary

Track-pads are the most cost-effective method for monitoring carnivore crossings in culverts, detecting 90% of tracks with visits every two days. Video-surveillance, however, captures more crossings overall and allows for behavioral analysis.

Area of Science:

  • Wildlife ecology
  • Conservation biology
  • Road ecology

Background:

  • Drainage culverts are assessed as habitat linkages for species, but sampling efficiency is often unknown.
  • Evaluating cost-effective methods for monitoring wildlife passage through culverts is crucial for conservation.

Purpose of the Study:

  • To determine the most cost-effective monitoring method for sampling carnivore culvert crossings.
  • To estimate the optimal interval between visits for track-pad surveys.
  • To compare the advantages of track-pad and video-surveillance methods.

Main Methods:

  • Track-pads and video-surveillance were used to monitor 15 culverts across two highways in southern Portugal over two sampling periods.
  • Data on animal tracks and crossings were collected and analyzed.
  • Cost-benefit analysis was performed to compare the two methods.

Main Results:

  • Track-pad surveys achieved 90% detection of animal tracks with a 2-day interval between visits.
  • Video-surveillance recorded more crossings (n=129) than track-pads (n=102), but detection varied by culvert type and species.
  • Circular culverts showed higher detection rates than box culverts with video-surveillance due to camera vision limitations.

Conclusions:

  • Track-pad technique is the most appropriate for cost-effective carnivore monitoring.
  • Video-surveillance offers advantages for year-round surveys and behavioral analysis.
  • Method selection should consider species, culvert type, and research objectives.
