Grizzly bears are brown bears. 

Charlie the bears in 16 are classed as browns, the grizzly class starts further north, it's related to the bears access to salmon I believe. Those that have salmon to eat on a regular basis are classed as costal browns and tend to grow larger.

So up in Alaska it sounds like they categorize the seasons by sub-species eh?  I knew there had to be more to it that the OP was asking that I wasn't aware of. 

The difference here it seems is that the costal bears tend to grow larger, so the demad for tags in those areas is much higher,while the areas may carry more bears per sq mile there is only so much costal land here. If your a NR paying 15 -20 thousand for a bear hunt[guide required] are you going for a big costal bear or a smaller harder to find interior grizz.? The castal brown and the Grizz are the same species.

While I have no great desire to add a Grizz rug to the house, I always check whats around the house, a few years ago there was a very nice bear just past the house about 2 mi working a small salmon stream, the bear was large enough to trigger interest , but after a couple weeks working the area it vanished. Found out a neighbor had killed it about a mile away as it worked a moose kill, it squared 9' 8". aside from one like that, I will go for an interior grizz, the blondes with the dark legs really catch my eye, and they are tough, they deserve respect and demand it.A few weeks back the wife & I were going with some friends on the local train north of Talkeetna, after the train had made a stop it started slowly around a bend and came up on a medium size sow with two cubs, she pushed the cubs north on the tracks and charged the train, a preformance she repeated for a half mile.A critter with that kind of guts has to be the greatest trophy in North America.
