How long is your season ?
What is your limit ?
How often are you checking traps ?
I suspect we do things quite different here !
Any time Marten are taken out of terrific habitat more Marten will eventually move in. My point is Marten from the country that is never touched are free to disperse into this now available habitat.
Your statement was just because there was habitat that did not mean there were Marten living there. Just where do the Marten live if not in good Marten habitat ?
Keep in mind we also must combine our limit with Fisher. Two Marten and three Fisher for instance. Marten are no friend of the Fisher I assure you. A fisher being much more aggresive and not real tolerable of Marten, or fussy about what he eats, a Marten would be a sufficent meal ! Kill a big Fisher and I believe I saved at least one litter of Marten !
Sure we exploit the area we can get to !! Put a lot of pressure on that small area we can access. Kill a couple of Marten and make room for a couple more to move in to take advantage of the recently vacated hunting grounds.
In 1995 we harvested 1500 Marten. Jump ahead to 06-07 season and we harvested 3788. Either we our getting dang good at it or the State has done a terrific job managing this fragile species !!
I have spent the last several years trapping Marten with the MN DNR Furbearer Specialist. He talks about charts and graphs and population models. The state does a very good job of protecting our resource. I believe the Marten are in good hands.
Yep I'm sure things are done differently in different places. Our season runs from Nov.1 through Feb 28 There is no limit in the area I trap. I check traps daily in November and less than that once it gets cool and animals slow their movements.
Well I would answer your question with another. How do you know it's "good" habitat ? Just because it looks good to us, doesn't mean it is. I know areas that produce no marten at all for many miles. Others produce hundreds per year. The areas look exactly the same to a human but obviously not to a marten. As far as in-migration, how far do you think marten will move in a given time period?
Yes I can see where removing a fisher would save a marten litter. That's good considering how small those litters are. I would think the state would encourage the taking of more fisher if they want to increase the marten. We have the same problem with foxes, wolves and wolverines eating marten kits.
I think there is another obvious answer to why the marten harvest in your area has more than doubled. More trappers in the country.
I'm sure your DNR folks are monitoring the situation. It just seems better to me to do everything possible to reduce female catches. Especially when you are using conibear type traps. It's nice to be able to release females. Of course that probably wouldn't make a difference in your area unless all trappers agreed to release them.
