Ive had a trail camera on a new permission for a month which I collected recently. I picked up a number of roe day and night for several days. Then I saw no deer but plenty of sheep as the sheep had got through a fence and stayed in the small area I was monitoring. Seems likely that the presence of the sheep had put the deer off entering the area. There was nothing else picked up on the camera eg human activity etc which could have explained the sudden absence of the roe.
