S-shape, but re-shape it if necessary. In addition, make sure that the wires are straight.
Baiting hair-snares
It is best to prepare hair-snares before going into the field. Place hair-snares and small carpet pads on a
table. The lure is already pre-mixed. Thoroughly shake or
stir the lure. Put 2 teaspoons (1/3 oz) of the lure on each
hair-snare and 2 teaspoons of the lure on each small carpet
pad. Spread out the lure on the pad as much as possible.
Squeeze dried catnip between your thumb and fingers to
help release the odor and sprinkle onto the hair-snare. The
amount of dried catnip per pad is the maximum the pad can
retain once it is lifted vertically, usually about 1 teaspoon.
No dried catnip is put onto the small carpet pad that is
hung from the tree branch.
Figure 5. Put 2 spoons of mixture on hair-snares and 2 spoons of mixture on small pads. Note that small pads are not shown in this picture.
Bait ingredients:
1:1: 6 ratio of propylene glycol, glycerine and beaver
castorium. Six drops per oz of catnip oil was added to this
mixture.

Habitat Measurements
Record topographic features using a clinometer for slope and a compass for aspect. Make sure your
compass has been adjusted for declination between true and magnetic north (declinations are provide on
USGS topographic maps). Provide elevation at stations using the most accurate source available.
Record over-story species and a visual estimate of over-story cover within approximately 30 ft of station.
Likewise, provide understory shrub species and a visual estimate of shrub cover within approximately
30 ft of stations. Give a visually estimated dbh of a typical over-story tree species.
