Migration Traps wanted
« on: September 05, 2009, 10:24:45 am »

So... I have this 6X6 untamed wilds map filled with Rhinos, Giant Anacondas and dinosaurs (dig deeper mod), and I want a reliable way to trap the wee beasties so that I can breed them into a perpetual sorce of bolts and leather. How would I go about doing this? I haven't seen a decent method of trapping for DF versions that have more than two Z levels, so could someone post some designs please?

Channel around the entire map, one entrance lined with cage traps. Everything entering the map goes through that one entrance.

If you don't want to do that however, placing a load of cage traps scattered liberally across the map is a good way to get a reasonable stream of wildlife for breeding purposes, as well as uncovering ambushes.

Removing ramps to funnel beasts into the traps can be a less invasive way than channeling and less labor intensive than building walls. If you have a larger hill/plateau and remove all but a few ramps and place cage traps at the remaining ones you can cover a lot of ground with a few traps. Same goes with a line across narrower passages and so on.

Hmph. I thought you were asking for methods of trapping dwarven immigrants, and got all interested.

Perhaps a drawbridge surrounded by cage traps, so that dwarves get bridgeapulted onto them and knocked out when they land so that they trigger? Or a one-z-level pit with a retracting bridge for a more controlled flight?

As for trapping migrating animals, I was able to create a somewhat effective "wall" for free on a wooded map recently by simply not ever designating a thin strip of trees for harvest. It eventually mostly filled up with impassible trees, and I put cage traps in the holes. It didn't catch everything but it did manage to snag quite a few of the beasties that passed that way.

Build barriers in large X shapes - channels, hillsides with slopes removed, walls, whatever.  In the middle, where the 4 legs come together, leave open and put your cage traps there.  Narrow passages with traps several deep.

The 4 triangular sections will work as funnels - the animals will tend to wander to the middle to get through.

If it's a dangerous map, add tunnels for reclamation and re-trapping.

Just put lines of cage traps around the corners of the maps

I've caught I don't even know how many Dromedaries.

I had a few pools near the edge of the map and just put my traps on thier corners.  The best spot was a narrow pond with a passage in the middle - I've caught TOO many elephants in that one.  Pools are a handy solution if you don't want messy digging all over your map (digging is for *underground*, my dwarfs tell me)
