Conclusion
Top 3 patterns
1) The trespassing service trucks we identified in 12.1. As explained, the movements by the trucks were the most suspicious among all the anomalies discovered. Further investigations are recommended to be conducted to find out what were they transporting in or out of the preserve – whatever it was, it would not be good for the preserve. Even the truck drivers were not hunting the birds directly, they might be transporting certain things that are harmful to the natural environments in the preserve, which in turn would affect the birds’ habitats.
2) The long stay duration car ID 20154519024544-322. This car recorded 281 visits to 10 gates, which shows a very suspicious loitering behavior. It could be moving around the preserve searching for something, could be the birds!
3) The movement of service trucks and sightseeing guests/coaches all night long. We observed that unlike the campers, the service trucks and sightseeing coaches move along the connecting paths all night long, going from one side of the preserve to another. The constant traffic at night might be a nuisance to the birds’ life, and caused the birds to migrate to other quieter places outside the preserve.
Besides the possible caused identified above, there is another area of concern – the fixed patrolling routine of the rangers. In our path analysis, we noticed that the rangers are working on fixed patrolling routes. It would be relatively easier for people with evil intentions to observe the patrolling routes and schedule, and plan their activities accordingly to avoid being caught. This might be a potential threat to the natural life in the preserve.
