I'm with Bannock.  I just use a candle to make my lint/pinecone/eggcarton starters.  Great for long winter evenings dreaming about canoe country.  I had also heard that using beaver wood is frowned on, I'm guessing as an effort to leave the lake shores in their natural state.  
I just spent 4 nights on the Turtle Flambeau Flowage with a couple of friends.   It rained a lot and was pretty chilly (had a great time, though).  I used birch bark to light all of our fires but the last.  On the day we left (last Tuesday) it was about 40 degrees and pouring rain.  We still had a decent woodpile and were all chilly with breaking the wet camp so I started a nice blaze with one of my starters.  Worked beautifully/impressed my friends.  I usually save them for emergencies, but it sure was nice to have a good fire near the tarp to warm up next to as we broke down.
Cheers,
