Title
Long-term growth, mortality and regeneration of trees in permanent vegetation plots in the Pacific Northwest, 1910 to present
Abstract
A network of more than 130 permanent vegetation plots provides long-term information on patterns and rates of forest succession in most of the major forest zones of the Pacific Northwest. The plot network extends from the coast to the Cascades in western Oregon and Washington and east to ponderosa pine forests in the Oregon Cascades. Most of the permanent plots were established during two intervals: from 1910 to 1948, and from 1970 to 1989. The earlier plots were established by U.S. Forest Service researchers to quantify timber growth in young stands of important commercial species and to help answer other applied forestry questions. The more recent period of plot establishment began under the Coniferous Forest Biome program of the International Biological Program during the 1970s, and continued under the Long-term Ecological Research program. A broader set of objectives motivated plot establishment since 1970, especially quantification of composition, structure, and population and ecosystem dynamics of natural forests. Plots have one of three spatial arrangements: (1) contiguous rectangles subjectively placed within an area of homogeneous forest; (2) circular plots subjectively placed within an area of homogeneous forest; and (3) circular plots systematically located on long transects to sample an entire watershed, ridge, or reserve. Rectangular study areas are mostly 1.0 ha or 0.4 ha (1.0 ac) in size (slope-corrected). Circular plots are 0.1 ha (0.247 ac), not corrected for slope. The tree stratum is the focus of work in closed-forest study areas. All trees larger than a minimum diameter (5 cm for most areas) are permanently tagged. Plots are censused every 5 or 6 years. Attributes measured or assessed at each census include tree diameter, tree vigor, and the condition of the crown and stem. The same attributes are recorded for trees (ingrowth) that have exceeded the minimum diameter since the previous census. In many plots tree locations are surveyed to provide a plot-specific x-y location. A mortality assessment is done for trees that have died since the previous census. The assessment characterizes rooting, stem, and crown condition, obvious signs of distress or disturbance, and the apparent predisposing and proximate causes of tree death.

Enumerated domain for attribute: DBH_CODE

Codes for DBH_CODE
Code Description
1 DBH estimated by linear interpolation or extrapolation
2 DBH estimated from growth rates of nearby trees of similar size
3 DBH estimated assuming 'no growth' (usually missing, non-vigorous, or damaged trees)
4 DBH estimated for individual boles using basal area of joint dbh of grown together (fused) trees
8 DBH is measured using a non-standard field procedure or estimated in the field
9 DBH estimated, method unknown or unspecified
G Good: normally measured DBH
M Missing: no measurement taken for missing or dead (mortality) trees
U Unknown: DBH is missing for a tree not listed as missing or dead
V Verified: excessive diameter change is acknowledged and accepted as described by comments
A DBH needs adjustment based on comments
5 DBH estimated for individual boles using USFS Forest Inventory and Analysis (FIA) method for Independent trees that grow together

Enumerated domain for attribute: CANOPY_CLASS

Codes for CANOPY_CLASS
Code Description
C Co-dominant: Crown extends to the top of the general canopy layer and receives light from the top but not much from the sides
D Dominant: Crown emerges from the general canopy layer and receives light from the top and the sides
E Emergent: crown extends completely above the canopy of the stand (only used in Stand RS39 in 1992 and HJHE stands)
I Intermediate: Crown extends into the lower portion of the general canopy layer and receives mostly filtered light from the top and the sides
S Suppressed: Crown completely beneath the general canopy layer
U Unknown or not measured
O Open grown: the tree is not taller than other trees in the stand but still receives light from all directions (e.g., a small tree growing in a canopy gap would be considered open grown). Only used in HJHE stands.
