The Path Analysis

Note: The path only has one sampling site that we would not cover in path analysis part.

Patterns	Visualization
1. Paths--3+4: The path 3 water flow: Sochair to Sakda. The path 4 water flow: Achara to Sakda Recent Period (from 2014 to 2016) In the recent years, the Total dissolved salts is only abnormal volatility during the past three years in the upper streams. Although the lower streams also have oxygen saturation and Bicarbonates, we can clearly notice that these two measure have greatly possibility come from Achars area (path 4). The mentioned two measures have greatly volatility in the Achars sampling sites at the same time period.
2-1.Paths:5+6+7 with past period he lower samping point Kannika which is end point of three sampling water path. But in the Kannika, the Oxygen saturation has increase in 2015 and 2016. And we also can exlude the reason that the measures come from Boonsri, because if measure suddently increase in Boonsri, it's next point Chai should be increase at the almost similar time, but in fact, the chai even never measure out the Oxygen saturation during that time. Therefore, we highlight the other potiential contaminated area.
2-2.Paths:5+6+7 with recent period In the kohsoom, there are more measure appears, for example Zinc . And in the past, the Bicarbonates volatility has relative small and Total coliforms has greatly changes in kohsomm, but it didn't has greatly volatility after 2013 Q4,where a little strange. And in the 2011, the upper sampling sites in three water path both have obviously change of bicarbonates.

Location Analysis

Note: The null measures in data set has been excluded s to avoid misunderstandings.

Patterns	Visualization
1.Campers Fig 7 provides the yearly visitor traffic calendar for the campers. The campers visited the reserve more often from May to Aug, possibly because this is the warm period of the year. The highest traffic of campers was observed in July 2015. There is a drastic drop in the campers, especially extended campers, from Q4 2015 onwards, which could be attributed to the colder weather.	700px
2. Rangers Trend Fig 8 below reveals weekly activity pattern for rangers. In 8.1, the heatmap was configured to show the average stay duration for the rangers at various gates. We noticed the rangers would stay for extended durations at camping 8 (Mondays, 10am to 14pm) as well as gate 2 & rangerstop 1 (Mondays 6am – 11am, Wednesdays 13 – 16pm). The rangers could be doing inspection or maintenance works at this these locations. Looking at the reserve map, we can observe that ranger stop 1 and camping 8 are both located at the “dead ends” of the reserve, with no paths extending beyond them – it is likely that these two locations are surrounded with floras whereby periodic maintenance is required. In Fig 8.2 we could see the rangers gathered at the rangerbase and gate 8 (which is in close proximity to the ranger base) on Thursdays 14pm. It could be an indication that the weekly ranger meetings were held on Thursdays 14pm at the rangerbase.	600px
