Technical Thematic Report No. 3. - Guidance for the preparation of ESTR products – Land classification scheme for the ecosystem status and trends report
- Aridity Index
- Ratio of mean annual precipitation to mean annual potential evapotranspiration
- % Cover/Crown Density
- “The percentage of a given area covered by the vertical projection of the aerial parts of plants of one or more species (Federal Geographic Data Committee, Vegetation Subcommittee, 1997).”
- Basal area
- “The area of the circle formed by the cross-section of a tree take 1.3 m above the ground (BC Ministry of Forests and Range, 2005).”
- “Trees classified botanically as Angiospermae in the subclass Dicotyledoneae; commonly referred to as deciduous or hardwoods” (National Forest Inventory, 2004)
- “Bryoids are defined as bryophytes (mosses, liverworts and hornworts) and lichens (foliose or fruticose; not crustose)” (National Forest Inventory, 2004)
- “Trees classified botanically as Coniferae; cone-bearing trees having needles or scale-like leaves, usually evergreen; commonly referred to as conifer or softwoods” (National Forest Inventory, 2004)
- Vegetation which loses its foliage seasonally.
- “Herbaceous plants other than graminoids, including ferns, club mosses, and horsetails.” (National Forest Inventory, 2004)
- “Herbaceous plants with long, narrow leaves characterized by linear venation; including grasses, sedges, rushes, and other related species” (National Forest Inventory, 2004).
- “Vascular plants without a woody stem, including ferns, fern allies, grasses, and grass-like plants.” (National Forest Inventory, 2004)
- “Woody perennial plants, both evergreen and deciduous, that have a relatively low growth habit, and are generally multi-stemmed, rather than having one bole. They differ from a tree by their low stature (generally < 10 m) and non-treelike form” (National Forest Inventory, 2004).
- A treeless area where growth is hindered by low temperatures and short growing seasons.
