I've not seen a Muntjac for several years. There's an unplanned nature reserve near us, where a triangle of land is blocked off by a motorway and two busy roads. there's a river running through it so the wildlife never has to struggle to find a drink.
I don't doubt the Muntjac, Kingfishers, and an amazing collection of wildlife still hold court there.
At one point you could walk along the river bed, under the motorway bridge, and reach one boundary of the 'reserve'. But that was as far as you could get because there was a a sudden deep hole in the river bed, which used to be a prime fishing hole when I was a schoolkid.
I've seen a kingfisher nest in the bank just there, and occasionally on moonlit nights, looking through the motorway bridge from the road road bridge I've seen a heron night-fishing. It's quite bizarre because you look through the darkness under the bridge and see a pool of light at the far end. Even without the moonlight there's a fair scatter of light from the motorway and the slip roads.
It's a little slice of 'a land time forgot', and in Spring and Summer, if you look down from the motorway it's a complete wilderness of bramble and wildflowers which have survived, even flourished, since it was a meadow. I'm sure most people never notice. I hope it stays that way. A self contained little eco-system.
Be a great place to hide a body, but you'd have to take it in via the river to avoid leaving an obvious trample-trail through forty plus years of undisturbed growth. ;-)
