Forest Insect and Disease Tally System (FINDIT) user manual

Publications Posted on: May 12, 2016
FINDIT, the Forest Insect and Disease Tally System, is an easy-to-use tool for analyzing insect and disease population information taken during stand surveys. Incidence of insects, pathogens, and other biotic and abiotic influences on forest ecosystems are summarized using traditional mensurational measurements. Information is summarized by diameter class, tree species, influencing agent, and for the entire stand.

Port-Orford-Cedar Root Disease

Publications Posted on: May 12, 2016
The most serious disease of Port-Orford-cedar (Chamaecyparis lawsoniana (A. Murr.) Parl.) is a root disease caused by the fungus Phytophthora lateralis. Nursery stock, ornamentals, and timber trees are subject to attack. Other species of Chamaecyparis are less susceptible than Port-Orford-cedar, and trees of other genera are not affected.

Innovative control and management of white pine blister rust – the proactive strategy for mountaintop ecosystems

Projects Posted on: December 03, 2014
RMRS and partners have developed a strategy to sustain healthy high elevation pine populations and mitigate the impact of invasion by the non-native pathogen that causes the lethal disease white pine blister rust. This approach provides the science foundation for proactive management.   

Chilling hours: Myths and facts

Publications Posted on: March 24, 2014
This paper is a critical review of over four decades of research on chilling with southern pine seedlings. For most pines, freeze tolerance, seed dormancy, and endodormancy of terminal buds are affected by natural chilling (0° to 8 °C [32 to 46 °F]). Unfortunately, in the field of reforestation, several myths have emerged regarding the importance of chilling.

Summary of taxa-specific research: 2. pathogens

Publications Posted on: May 31, 2013
Damage caused by invasive forest pathogens is widely viewed as more severe, long-term, widespread, and difficult to restore than that caused by any other biological disturbance agent. In the last century, pathogens introduced into our native forests have threatened extinction of native tree species and critically degraded many different ecosystems across North America.
