ABSTRACT:
A method and apparatus for providing notification of the falling motion of a tree. An angular sensor produces a sensor signal when its angle is changed beyond a predetermined angle by the falling motion of the tree to which the angular sensor is attached. Receipt of the sensor signal causes a transmitter to send an alarm signal over a 900 MHz spread spectrum channel to a receiver. The receiver generates a vocal message which is, in turn, cyclically sent over a wireless or wired telephone link to a law-enforcement agency or a party representing the landholder. If a particular telephone in the cycle of telephones does not answer, the receiver attempts to connect over another telephone link.
