I'm just back from a trip to try to spot brown hares here in Carmarthenshire.
I was near the village of Brechfa and joined Vaughn Mathews who works with the Wildlife Trust Wales and is currently coming to the end of a three year hare survey of Wales.
It's estimated that there's been a 75% drop in hare numbers in Wales since WWII, but the survey is trying to establish if areas which are being sensitively managed are seeing a resurgence in numbers.
Farmland run as part of the Welsh Government's Tir Gofal scheme is being compared with land which is not part of any agri-environment projects.
We climbed a steep hill, slowly, looking carefully for any signs of hare, but as Vaughn explained, we were unlikely to see any in daylight.

He told me that most of his sightings have been at dawn or dusk and that 3 years on, he still finds it a thrill to spot a brown hare: "They're just such charismatic creatures," he says "they can be so secretive and then sometimes, you can see them plainly, boxing together or bouncing along a field."
"I've also spoken to many farmers who say they'd like to see more hares on their land and wonder how they can attract them."
Hares are quite choosy though and apparently they don't like to share their living space with rabbits, sheep or people for that matter, and prefer to be around cattle, probably because they don't graze the grass so low.
Intensive farming methods, the loss of mixed farming systems and higher stock levels are all being blamed for dwindling hare numbers.
Vaughn wouldn't be drawn on any of the surveys findings, which are due to be published in the Spring, but he hinted that there could be a few surprises in store.

After a steep climb, several tricky farm gates and a lot of wading through thick mud, sadly we didn't spot any hares today.
But the Wildlife Trust Wales is asking for members of the public to get involved with the survey, by reporting any sightings of this reclusive animal.
