Book Description
Catastrophes and manipulation of stocking levels are important determiriants of stand development and the appearance of future forest landscapes. Managers need stocking level guides, particularly for sites incapable of; supporting stocking^ levels presented in normal yield tables. Growth basal area (6B^) has been used by some managers in attempts to assess inherent differences in site occupancy but rarely has been related to Gingrich-type stocking guides. To take advantage of information currently available, we used some assumptions to relate GBA to stand density index (SDI) and then created stocking level curves for use in northeastern Oregon and southeastern Washington. Use of these curves cannot be expected to eliminate all insect and disease problems. Impacts of diseases, except dwarf mistletoe {Arceuthobium campylopodum Engelm.), and of insects, except mountain pine beetle {Dendroctonus ponderosea Hopkins) and perhaps western pine beetle {Dendroctonus brevicomis LeConte), may be independent of density. Stands with mixed tree species should be managed by using the stocking level curves for the single species prescribing the fewest number of trees per acre.

Book Description
The work described in this report was initiated during the Interior Columbia Basin Ecosystem Management Project (ICBEMP). The ICBEMP produced a broad-scale scientific assessment of ecological, biophysical, social, and economic conditions for the interior Columbia River basin and portions of the Klamath and Great Basins. The broad-scale assessment made extensive use of potential vegetation (PV) information. This report (1) discusses certain concepts and terms as related to PV, (2) describes how a PV framework developed for the broad-scale ICBEMP assessment area was stepped down to the level of a single section in the national hierarchy of terrestrial ecological units, (3) describes how fine-scale potential vegetation types (PVTs) identified for the Blue Mountains section were aggregated into the midscale portion of the PV hierarchy, and (4) describes the PVT composition for each of the midscale hierarchical units (physiognomic class, potential vegetation group, plant association group).
