practice of planting trees in areas where trees were not previously present

practice of using trees as part of a land management strategy for help with food crops or pastures

layer of the forest where most mature trees provide the thickest coverage of leaves and branches

logging method where all growth is cleared from an area, regardless of age or type of plant

particularly burnable or easily burned

evergreen trees with needle-shaped leaves

forest layer made up of trees with crowns reaching above the canopy

area dominated by tree species which receives enough annual precipitation to maintain trees as the dominant form in the landscape

bottom layer of the forest, covered in detritus such as decaying leaves, fallen trees and animal scat

practice which includes surveys, categorization and monitoring of forests

forest layer covered by herbaceous plants; receives very little light

logging method; involves only cutting down the biggest or most valuable tree species in an area

non-native species introduced to an area which ultimately harm the ecosystem or human health

sub-layer right below the canopy; young trees stay dormant until a mature tree falls

state of being frozen year-round

material created by atmospheric condensation falling, such as rain, snow, sleet or hail

controlled fires used by experts to clear fire fuel from forests safely

method used to replant trees in the same habitat where older ones were removed

sand, stone or soil carried into land or water

only logging the most mature trees in an area

some desirable trees are left standing to ensure the ecosystem has the opportunity to establish healthy seedlings

forest layer full of plants with woody stems, such as bushes and shrubs

process of trees releasing water through their leaves

occurs when a tree is stressed due to pests, pollutants, drought or other unmet growing conditions

forest layer made up of young trees, or saplings

Wildland Urban Interface

area where urban structures or buildings exist on land with more than 50 percent vegetation
