The following trapping techniques are used with reptiles and frogs:
pitfall traps
active searches
spotlighting
tape recording
drum nets
Pitfall traps![top of page](img/top.gif)
Target group: lizards and frogs
Description: small to medium size hole dug into the ground
and plastic bucket placed inside. A drift-fence (variable height
and length) is placed on ground to intersect with bucket.
Active searches![top of page](img/top.gif)
Target group: all reptiles
Description: active searches are deliberately timed in a
fixed locality where habitat is physically disturbed in order to
uncover animals that may be hiding. A passive search on the other
hand would involve simply observing animals for a fixed period (see
birds).
Spotlighting![top of page](img/top.gif)
Target group: geckoes, frogs, and snakes
Description: similar to active searches, but done at night.
Tape recording![top of page](img/top.gif)
Target group: frogs
Description: many species of frog are difficult to locate
due to cryptic behaviour. Use any type of tape recorder to record
frogs calling. Make sure you note the type of habitat, date, and
any other feature that may be helpful later on to distinguish calls.
Later, you can compare your calls with tape recordings of known
frog calls (these are sometime available from local naturalist groups).
Alternatively, local frog specialists may be able to give assistance.
Drum nets![top of page](img/top.gif)
Target group: freshwater turtles
Description: large drum net, baited with meat, for sampling
turtles. Attached by rope to overhanging tree branch. It is important
to keep part of the net above water and to regularly check nets
to avoid injuring the captured animals.

turtles. Wildlife Research 19:443-445.
