Australia doesn't have any 11,000 feet mountains! 7,310 feet is our highest (Mount Kosciuszko) so by our standards, Mount Feathertop at 6,306 feet is a big one.
In Australia, alpine refers to areas where due to elevation trees can't grow and vegetation is restricted to dwarfed shrubs, alpine grasses and ground-hugging herbs. In Victoria, that occurs at about 6,000 feet.
Alpine has the same meaning here but in Colorado it starts at 11,000 ft. I was wondering why it starts at 6,000 in Victoria but 11,000 in Colorado. I could have worded it a lot better though. The further one goes north on our continent the lower the treeline but you have to go all the way up to Montana to get close to a 6,000 feet treeline. I assume the lower elevations in Victoria have milder winters than those of Montana.
Interesting, I live higher than Mount Kosciuszko by about 150’.
Hope this fellow comes out alright.
