What is the X in X-mas?
vegetation type with a more or less continuous canopy of broad-leaved trees. Such forests occur between approximately 25 and 50 latitude in both hemispheres (see). Toward the polar regions they grade into boreal forests, which are dominated by evergreen conifers, so that mixed forests containing both deciduous and coniferous trees occupy intermediate areas. Temperate forests usually are classified into two main groups: deciduous and evergreen.
