Method and Device for Monitoring Integrity of Wooden Posts A device (10) for monitoring the integrity of a wooden post (40) comprises an outer sleeve (11), a moveable pin (12), driving means (24) and indicating means (50). The outer sleeve (11) is adapted to be mounted in a pre-formed recess (41) of complementary size and shape extending from the outer surface (43) of a wooden post (40) substantially into the centre (45) thereof. The moveable pin (12) is mounted within the outer sleeve (11) and has a head (18) arranged normally to bear against wood at the centre (45) of the post (40). The driving means (24) is arranged to urge the pin head (18) against wood at the centre (45) of the post (40). The indicating means (50) denotes any movement of the pin (12) further into the post (40). When in use in a method of monitoring the integrity of a wooden post (40), the device (10) is located in a pre-formed recess (41) and the indicating means (50) is used periodically to monitor any movement of the pin (12) further into the post (40).
