Did you know?
The word krummholz is derived from German word krumm, meaning crooked, bent, or twisted; and holz for wood. High winds and frozen preciptation at high elevation causs the stunted, gnarly, and sometimes "flagged" growth forms in woody plants in this community. This community is restricted to the high-elevation slopes of mountainous areas generally above 3,500 feet.

State Ranking Justification [-]
There are only 10 to 20 occurrences statewide. There are several occurrences protected on state land. This community is restricted to the high-elevation slopes of mountainous areas generally above 3,500 feet, and includes several high quality examples averaging slightly over 100 acres each. The current trend of this community is probably declining slightly due to the combined effects of atmospheric deposition and recreational overuse.
