Using data collected from 425 locations of an agouti collar on the island we generated a first generation predictive range model. This was based on a relationship between the signal strength of a transmitter and its distance from the receiver, its elevation, and is aspect relative to the tower; this explained approximately 2/3 the variance. Using this relationship, we can estimate the number of towers that will be able to detect this transmitter throughout the island. This model is shown here, with grey being no detection, orange being detection from one or two towers, and darkening shades of green being more and more towers. Additional testing has shown this model to be pessimistic for the island perimeter (we do detect transmitters on the peninsulas) and optimistic for the island center (we don’t get detection from quite so many towers). The purple dots are the tower sites, the purple box is the 50-ha tree plot, black lines are trails.
