|Jen sets up the trap on our first night|
The first evening, our 10 Longworth traps were filled with hay bedding, chunks of carrot and apple, rolled oats (all sounding very good so far...) And then we added casters - fly pupae used by fishermen as bait. The smell and look of these certainly turned our stomachs, but apparently mice find them irresistible!
|This tasty combo was sure to bring out the small mammals of our woodland...wasn't it?!|
We laid the traps every 10m along a 100m transect through the woodland in a range of habitat. On the first night the traps were locked open. This was known as the acclimatisation period, allowing mice to get used to the traps, and enjoy our offerings without being trapped.

On the second night we replenished the food in the traps. We were excited to see evidence that something had entered some of the traps for a quick snack over night.
|Toothmarks on this piece of carrot were evidence of nibbling...|
|...and again on this piece of apple. Things were looking good!|
|Jen, Rachel and Bruce refill the traps with food. Stand back its the smelly casters!|
The traps were then replaced, this time set to lock shut when anything walked over the trip wire inside.
|Rachel and Jen reset trap to lock on night 2|
The traps were placed in bramble, under ivy and in log piles. We had a good feeling about these last ones - would we be right?!

|John inspects the contents of a trap on the last morning|
Trap by trap a similar pattern was occurring - open doors! This indicated nothing was trapped inside, but we continued the checks just in case. It soon became clear however that fortune was not on our side and we hadn't caught any mini mammals this time. However, our wildlife count was not zero - we saw plenty of slugs were taking advantage of the free feed, and spotted a few woodlice and spiders in the hay bedding. Nice to know our efforts weren't entirely wasted!

Our theory concluded that the slugs had often wedged the traps open allowing mice to come and go freely. We noted the woodland was in good shape and could still see blackberries on the bramble so we have no reason to be concerned that we didn't find any small mammals this time. And who wouldn't choose fresh blackberries over carrots and casters?!
