Abstract: We developed two types of snares incorporating barbed wire for obtaining hair samples from raccoons (Procyon lotor) suitable for DNA analyses. The hair snares were a wood box with a single strand of barbed wire positioned 20 cm above the lower edge of the entrance and a 5 gallon bucket with 2 strands of barbed wire in an inverted ā€˜Vā€™ position. Snares were placed from August to November 2005 along forested roads in the central Upper Peninsula of Michigan. Both hair snares collected samples suitable for DNA analyses; however, the number of hair samples collected/100 snare nights was greater (P < 0.001) for bucket snares (n = 36) than for wood box snares (n = 5). Capture efficacy was also greater (P = 0.013) for bucket snares (91%, n = 35) than for box snares (68%, n = 44). The overall number of hairs collected at bucket snares was greater (P = 0.021) than the number of hairs collected at wood box snares. Barbed wire was an effective medium for obtaining hair samples from free-ranging raccoons. Because of greater performance, low cost, and ease of construction, we recommend use of bucket snares over wood box snares.
