Effects of wildfire severity on small mammals in northern Arizona ponderosa pine forests

Publications Posted on: May 12, 2016
We examined effects of a varied-severity wildfire on the community structure of small mammals and populations of the 2 most abundant species, the deer mouse (Peromyscus maniculatus) and the gray-collared chipmunk (Tamias cinereicollis), in northern Arizona ponderosa pine (Pinus ponderosa) forests. We examined 2 fire severities and compared them to unburned controls.

Effects of urbanization and recreation on songbirds

Publications Posted on: May 12, 2016
This chapter discusses how urbanization and recreation in Southwestern ponderosa pine forests might influence songbirds and comments on the research necessary to provide an assessment of future affects.

A historical overview

Publications Posted on: May 12, 2016
This chapter reviews the historical: 1) occupancy, use of and impacts on ponderosa pine forests by early American Indians and European settlers; and 2) the human use of and impacts on birds in ponderosa pine forests. Contemporary ecology and human use of ponderosa pine forests are described in this publication by Moir et al. and Raish et al.

Service life of treated and untreated Black Hills ponderosa pine fenceposts

Publications Posted on: May 12, 2016
Service-life tests indicate that ponderosa pine fenceposts treated with preservatives performed well after field exposure of 30 years. Treating plants in the Black Hills area used commercial methods to treat the posts with creosote, pentachlorophenol, and waterborne arsenicals. Test sites were in the northern Great Plains-one in the semiarid western portion near Scenic, South Dakota, the other in the more humid eastern portion near Brookings.

Low-severity fire increases tree defense against bark beetle attacks

Publications Posted on: April 21, 2016
Induced defense is a common plant strategy in response to herbivory. Although abiotic damage, such as physical wounding, pruning, and heating, can induce plant defense, the effect of such damage by large-scale abiotic disturbances on induced defenses has not been explored and could have important consequences for plant survival facing future biotic disturbances.

Forest vegetation of eastern Washington and northern Idaho

Publications Posted on: March 29, 2016
The forest vegetation of the northern Rocky Mountains is potentially a rather simple mosaic determined by macroclimate, microclimate, soil fertility and soil drainage. In actuality, however, the vegetation consists mainly of a wide variety of intergrading, disturbance-induced communities that are difficult to treat except as developmental series related to specific climaxes.

Mark-recapture estimation of snag standing rates in northern Arizona mixed-conifer and ponderosa pine forests

Publications Posted on: October 07, 2015
Snags (standing dead trees) are important components of forests that provide resources for numerous species of wildlife and contribute to decay dynamics and other ecological processes.

The habitat types

Publications Posted on: August 14, 2015
Nearly everywhere in eastern Washington and northern Idaho as one leaves the steppe at the foot of the mountains and enters the forest, the first coniferous tree encountered is Pinus ponderosa. The ability of this species to endure dry climates· well exceeds that of our next most drouth-tolerant conifer, Pseudotsuga menziesii. Therefore, typically a belt of climax pine forest separates steppe from Pseudotsuga forest.

Geographic variation in ponderosa pine leader growth

Publications Posted on: August 14, 2015
Growth of the shoot apices of 91 trees in a 45-year-old Pinus ponderosa Laws. provenance test was measured periodically with a transit.

Injury to plants from rapidly dropping temperature in Washington and northern Idaho

Publications Posted on: August 14, 2015
In nearly 70 years of recorded weather history, Washington and northern Idaho have on three occasions experienced exceptionally sharp freezes in late autumn or early winter that caused considerable damage to plants. A brief review of these events is warranted since the records are consistent enough to permit the drawing of significant conclusions.
