What is the wildlife requirements for a Type 3 harvest (select all that apply)

Leave per acre on average 2 down logs - 6' + long & 10 cubic feet - 50% conifers

No need of leave trees for type 3 harvest

Leave per acre on average 2 wildlife trees (snags or green trees) - 30' + tall & 11' + DBH - 50% conifers

What are the OFPL requirements (select all that apply)

It is the responsibility of the landowners to establish trees after harvest

Every harvested acre must be replanted within 2 yrs after harvest

It is the responsibility of the state of Oregon to establish trees after the harvest

Within 6 years seedlings must be "free to grow" and well established

Advantage of use of EXOTIC species are used for timber production (select all that apply)

Faster Growth

Known impact on wildlife

Adaptation Ensured

Advantage of using NATIVE species are: (select all that apply)

Adaptations Ensured

Known Impact on wildlife

Faster Growth

About seed zones, from the following statements, what is true? (select all that apply

Seed zones are independent of soil and climate

Seed zones are developed from common practice garden studies

Seed Zones limit transfer of seeds within a region

Characteristics of Seed Orchards are (select all that apply)

Flower induction treatments include crown pruning

Flower induction treatments include hormone application

Flower induction treatments include partial girdling

Trees have narrow crowns

Characteristics of an Open Pollinated seed orchard are (select all that apply)

The exact pedigree of seeds produced is known (father and mother)

Easy to produce large quantities of seeds

Produce seed with maximum genetic gain as there is no pollen contamination

Female cones are freely pollinated from surrounding trees

Advantages of P+1 bareroot seedling (select all that apply)

Characteristics of a container nursery are ( select all that apply)

Seedlings can be frost hardened by manipulating water availability

Seedlings can be frost hardened by root pruning

Seedlings are grown in bareground

Seedlings can be frost hardened by manipulating light availability (day length)

About a "target seedling". Please indicate what is true: (select all that apply)

A target seedling is an all purpose seedling

Plant quality depends on how plants will be used

Target seedling quality is independent of site characteristics

Nurseries develop stock types for specific outplanting projects

Consider genetics (local adaptations and genetic diversity)

About morphological assessments of plant quality, please indicate what is true (select all that apply)

Growing seedlings at narrow spacing in the nursery or greenhouse (more seedlings per m2) will produce more seedlings with smaller diameter class

For douglas-fir a good height (cm) to diameter (mm) ratio (sturdiness) is about 10:1

For douglas-fir a good shoot to root ratio (volume or mass) is about 1:1

About physiological assessments of plant quality, please indicate what is true (select all that apply)

Cold hardiness can be modified by manipulating irrigation and/or daylength (blackout)

Cold hardiness index (LT50) is the temperature at which 100% of the seedling (or tissue) are killed

Cold hardiness is evaluated using a pressure chamber (water potential)

Exposure to low temperature increase cold hardiness

What kind of trait would make most sense to select for a conifer breeding program

High economic value, good variation, moderate heritability

Zero economic value, good variation, very high heritability

High economic value, little variation, unknown heritability

Which sentence correctly describe the functions of progeny tests vs realized genetic gain trials?

Realized gain trials are designed to select new forward selections for the next generation breeding

Progeny tests are designed for precise ranking of families and select new superior genotypes for breeding and seed production

Progeny test are designed to give reliable predictions of rotation-age realized genetic gains in typical operational conditions
