Elevations in the Bryophyte Volumes:
How to state them

Elevations in the Flora of North America North of Mexico are usually stated as a range of meters, rounded off to the nearest 100 m, rounded down for the lower elevation and rounded up for the higher.

Given the microclimatic influence on habitat for bryophytes, elevation is less determinative of location. Many authors do not have information or find it extremely general.  For this reason, the bryophyte volumes will have elevations reported somewhat differently.

If you do not have elevations reported in meters, make an educated guess from the known distribution of the general elevation of most collection stations. Use the following ranges and terminology:

1--199 m = low elevations;  200--1599 m = moderate elevations;  1600+ m = high elevations.

(Note: Denver is about 1600 m, the high point on the Plains.) Put the phrase between semicolons between the habitat info and the distribution (provinces/states) info in the distribution sentence. Examples:  ; low to high elevations;  or ; moderate elevations; or ; moderate to high elevations;

IF you do have meter ranges, insert the general phrase and put the meter ranges in parentheses after the general phrase. E.g. ; low to moderate elevations (100--1400 m);

Use 0 (zero) for sea level or less than 100 m.
