The browse line, and their trails, inside the wood will be a clear indicator of Muntjac ; they really are creatures of habit. If there is a brook running through it even better, a high water table will be keeping their browse in good condition.
I took on a very small permission for Muntjac recently, had the land cleared (footpath, road, housing all adjacent), high seat, and patience. Forget going out at last light, get there before daybreak, so this week (mid-July) set up before 04.00 ; one tiny corner 30 metres by 30 metres has yielded five does in six dawn outings since 26th June.
Best of luck, S
