pitfall traps Pitfall traps 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 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 Description: similar to active searches, but done at night. Tape recording 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 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. see Kennett, R. (1992). A new trap design for catching freshwater turtles.
