Seedling establishment and physiological responses to temporal and spatial soil moisture changes

Publications Posted on: March 03, 2016
In many forests of the world, the summer season (temporal element) brings drought conditions causing low soil moisture in the upper soil profile (spatial element) - a potentially large barrier to seedling establishment. We evaluated the relationship between initial seedling root depth, temporal and spatial changes in soil moisture during drought after outplanting, and subsequent seedling performance using seedlings of Pinus ponderosa Laws.

Growing container seedlings: Three considerations

Publications Posted on: December 16, 2015
The science of growing reforestation and conservation plants in containers has continually evolved, and three simple observations may greatly improve seedling quality. First, retaining stock in its original container for more than one growing season should be avoided. Second, strongly taprooted species now being grown as bareroot stock may be good candidates for container production.

Establishing big sagebrush and other shrubs from planting stock

Publications Posted on: October 06, 2015
Bareroot or container seedlings can be used to quickly re-establish big sagebrush and other native shrubs in situations where direct seeding is not feasible or unlikely to succeed. Guidelines are provided for developing a planting plan and timeline, arranging for seedling production, and installing and managing outplantings.

Target seedling strategies for intensively managed plantations in the Oregon Coast Range

Publications Posted on: February 27, 2012
The target Douglas-fir seedling for outplanting on Roseburg Resources Company timberlands is a least-cost, large [stem] caliper 1- to 2-year old bareroot (>8 mm) or container (>6 mm) seedling with good form, high root growth potential, and the ability to withstand browse without the use of browse deterrents.

Establishment and growth of container seedlings for reforestation: A function of stocktype and edaphic conditions

Publications Posted on: June 03, 2011
A properly selected stocktype can greatly enhance reforestation success through increased survival and growth following outplanting. Implementing a robust stocktype trial using stocktypes of equal quality can ensure results lead to the best choice. Six container types, differing primarily in depth and volume, were used to evaluate the performance of ponderosa pine (Pinus ponderosa Laws. var.

Growing reforestation conifer stock: Utilizing peat/sawdust medium

Publications Posted on: May 19, 2009
Western Forest Systems, Incorporated (WFS) (Lewiston, ID) has been utilizing a peat/sawdust blended mix as our growing medium for the past 10 years. Our decision to change from a peat/vermiculite blend to a peat/Douglas-fir (Pseudotsuga menziesii) sawdust blend involved worker health and safety issues, seedling culture, seedling production, and economic impact.

Comparing growth of ponderosa pine in two growing media

Publications Posted on: May 19, 2009
I compared growth of container ponderosa pine (Pinus ponderosa) seedlings grown in a 1:1 (v:v) Sphagnum peat moss:coarse vermiculite medium (P:V) and a 7:3 (v:v) Sphagnum peat moss:Douglas-fir sawdust medium (P:S) at three different irrigation regimes. By using exponential fertilization techniques, I was able to supply seedlings with similar amounts of fertilizer over time even though irrigation frequency differed.

New pine planting strategies for the Western Gulf States

Publications Posted on: September 29, 2008
The structure of forest industry has experienced major changes over the last few years, both domestically and globally. Mills are closing, companies are merging, and forest products corporations are divesting their lands. The demand for smalldiameter trees in the southern United States has diminished largely due to the amount of wood fiber and wood products now available from other countries around the world.

Blackout cloth for dormancy induction

Publications Posted on: September 29, 2008
The use of blackout cloth to create long night photoperiods for the induction of dormancy in certain conifer species has been an established practice for a long time. Its use was suggested by Tinus and McDonald (1979) as an effective technique, and the practice has been commonly used in Canadian forest nurseries for a number of years. Cal-Forest Nursery installed its first blackout system in 1998 after a visit to several Canadian nurseries.

Survival and Growth of Container and Bareroot Shortleaf Pine Seedlings in Missouri

Publications Posted on: March 13, 2007
Shortleaf pine (Pinus echinata Mill.) seeds collected from several half-sib families were grown as both container and bareroot stock and outplanted in two tests at the George O White Nursery in Licking, Missouri. After eight growing seasons, 2-year-old container seedlings had significantly better survival than 2-year-old bareroot seedlings, while survival of the 1-year stocktypes was not significantly different.
