Rapid Response Reforestation: Studies in Fire Restoration

Publications Posted on: May 12, 2016
The Nursery Technology Cooperative has been conducting projects to examine forest seedling quality and reforestation success in the Pacific Northwest for more than 20 years. Because of the large wildfires in recent years, there is a growing interest in studying reforestation strategies for optimum restoration following a fire. We have developed 2 “Rapid Response Reforestation” projects to address common reforestation issues in burned areas.

Light-emitting diode lighting for forest nursery seedling production

Publications Posted on: September 02, 2015
Crop lighting is an energy-intensive necessity for nursery production of high-quality native plants and forest tree seedlings.

Growing native plants with biochar

Projects Posted on: April 16, 2015
Rocky Mountain Research Station scientists and their partners are evaluating biochar as a seed coating and as an amendment to nursery substrates to improve germination and growth of native plants. The goal is to reduce costs associated with restoring ecosystems.

Phytosanitation: A systematic approach to disease prevention

Publications Posted on: March 24, 2014
Phytosanitation is not a new concept but has received renewed attention due to the increasing threat of nursery spread Phytophthora ramorum (PRAM), the fungus-like pathogen that causes Sudden Oak Death. This disease has the potental to become the most serious forest pest since white pine blister rust and chestnut blight. Phytosanitation can help prevent the spread of this and other pathogens to or from nursery operations.

Lengthened cold stratification improves bulk whitebark pine germination

Publications Posted on: March 24, 2014
Crucial to the restoration of whitebark pine (Pinus albicaulis) ecosystems is the ability of forest managers to locate, propagate, and reintroduce viable, disease-resistant populations to these jeopardized systems. Currently, one of the most limiting steps in this process is the slow, labor-in - tensive, and expensive process of producing whitebark seedlings at forest nurseries.

Designing propagation environments in forest and native plant nurseries

Publications Posted on: March 24, 2014
Propagation environments are areas that have been modified for plant growth, and can be designed using the law of limiting factors. Identifying critical factors that are most limiting to optimal plant growth is helpful when developing both bareroot and container nurseries. Propagation environments can be categorized into minimally-controlled, semi-controlled, and fully-controlled. The defining characteristics of each are discussed.

Target Seedling Symposium: Proceedings, combined meeting of the Western Forest Nursery Associations

Publications Posted on: October 29, 2013
This publication, a compilation of 28 technical articles on various aspects of forest nursery management in western North America, consists of two sections. The first 10 papers comprise the Target Seedling Symposium, and discuss the latest methods of describing and measuring the ideal seedling for reforestation purposes. Morphological characteristics such as height, diameter, stocktype, root system size, and mycorrnizae are covered.

The target plant concept-a history and brief overview

Publications Posted on: February 24, 2012
The target plant concept originated with morphological classification of conifer nursery stock in the 1930s, and the concept was enhanced through physiological research and seedling testing towards the end of the century.

Restoration strategies for a native perennial: Germination and seedling physiology of Sphaeralcea munroana

Publications Posted on: October 04, 2011
The Great Basin region of the western United States has undergone significant disturbance and fragmentation because of overgrazing for livestock production, disruption of the natural fire regimes, and the introduction of non-native species. At present, habitat loss greatly surpasses the rate of system recovery, making restoration integral to ecosystem function and resilience.

Sulfometuron methyl: Its use in forestry and potential phytotoxicity

Publications Posted on: April 08, 2011
Planting site preparation is a common practice used to enhance seedling establishment success. Site preparations include herbicide, fire, and mechanical methods. Studies designed to explore the use of herbicides as site preparation and release tools are common, and herbicides have shown their use in forestry to be logistically, economically, and ecologically advantageous.
