Where are the Dogs?

Picture
 We have started fitting domestic dogs from surrounding villages with passive GPS tracking devices.  We plan to document their movements into Khao Ang Rue Nai Wildlife Sanctuary (KARN) and eventually determine the proportion of overlap in the home ranges of dogs and dholes.  This will help us perform an analysis of disease transmission risk.  My terrific field assistant, LungDaeng, is in charge of collar deployment and download while I am back at UMass for the fall semester.  He has never used a computer before, so teaching him to download and save a GPS file was an adventure in patience.  The key was for him to write the directions in his own words, step-by-step.  

Testing of collars in July showed active dogs that roam across the main sanctuary road.  The yellow lines on the above map show the path of a 10 year old female from 10-23 July, 2010.  The main road 304 of the sanctuary is visible west to east in white.  The red line delineates the boundary of KARN.  Forest to the west of the line is inside the sanctuary.
