Camera Trap Analysis 2014/2015

At the end of this week my camera trap will have been running 24/7 for 2 years and so I am now beginning to look at the ways in which I can analyse the data. Last year I looked at the 2014/15 data and produced some weekly graphs showing abundance and some interesting distributions of activity in the mammals. I also wrote a short report on the Badger.

This time I have started to look at when during the day or night they are most active. Each of the following graphs show the culmination of all sightings over the 52 weeks in the 2014/15 season. At the end of next week I will do the same for the 2015/16 season. I will also break up each year into seasons to compare activity times throughout the year.

 This graph shows the percentage of each mammal species recorded in the first year

 This graph shows that the Badger is wholly nocturnal and most active along the hedge line in late evening.

 With the Fox you can see periods of activity across the night with an interesting dip between 8 and 11 pm. It is also possible to see low activity during the day.

 The Muntjac shows several bursts of activity. There is a dominant peak that relates to dusk and again a small peak at dawn. There is some evidence of some daytime activity.

 The Wood Mouse, as expected, is completely nocturnal, with not real spikes in activity but seem most active between 1 am and 3 am.

The Grey Squirrel is a fully daytime species with an even distribution of activity across the day with a peak at Mid-Day.

Lastly this is a list of the species recorded across the whole 2-year survey period.
