Temperatun: Some evergreen woody plants and many g<strong>as</strong>ses grow through the winter. Typically, the winter frosts<br />
restrict occurrence of broad-leaved evergreen trees.<br />
freciipttation: Not limiting under the typical humid precipitation pattern, except for short dry periods in most years,<br />
Major veetation types: Mainly deciduous hardwood or conifer forests, with many mixtures of the two. Heath<br />
grows under coolest marine climates.<br />
Ground-story vegctation: Under forest canopy the woody plants are tree seedlings, vines, and scattered shrubs.<br />
Heath or gr<strong>as</strong>s occur outside of forest types.<br />
Amount: Low to moderate dry weight.<br />
Moisture content: High most of year; lowest in the Fall.<br />
Litter layer: Mainly current leaf fail and gr<strong>as</strong>s rough; some accumulation of old dead material, especially in coolest<br />
Total available fuel weight on a good burning day: 0.16 pounds per square foot in hardwaods; 0.23 pounds per<br />
square foot in conifers.<br />
Burn days: No bum se<strong>as</strong>on; best odds during driest Fall months.<br />
Desiccation needs: Must remove forest canopy and kill understory woody plants for successful burning. Use either<br />
a foliage spray or an application of pellets to the soil.<br />
