Open forests of savanna and woodlands span the spectrum between closed canopy forests and treeless grasslands, and therefore contain structure, composition, and function distinctive from either endpoint. In this special issue, researchers provide examples from different open forest ecosystems to examine the underlying ecological principles and specific management challenges affecting successful restoration of these systems.

For centuries, western white pine (Pinus monticola) dominated moist forests of the northern Rocky Mountains. The fast-growing species, which can reach heights of 150 feet, was once an economic driver in the region. However, not much of the former forest remains. A combination of blister rust, beetles, and logging severely reduced the range of white pine during the 20th century.

Douglas-fir, Pseudotsuga menziesii (Mirb.) Franco, trees and stands can be protected from Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins (DFB)-caused mortality by application of synthetic formulations of the beetle’s antiaggregation pheromone, 3-methylcyclohex-2-en-1-one (MCH).

Many research studies and syntheses have suggested that prescribed fire (Rx fire) and wildland fire use fires (WFU) are perhaps the most effective tool for restoring whitebark pine ecosystems (Murray et al. 1995, Keane et al. 2012, Perkins 2015, Keane 2018). Rx and WFU fires can kill competing conifers; reduce surface and canopy fuels; and create attractive sites for nutcracker caching.

This paper presents a prototype Carbon Monitoring System (CMS) developed to produce regionally unbiased annual estimates of aboveground biomass (AGB). Our CMS employed a bottom-up, two-step modeling strategy beginning with a spatially and temporally biased sample: project datasets collected and contributed by US Forest Service (USFS) and other forestry stakeholders in 29 different project areas in the northwestern USA.

Climate warming is increasing fire activity in many of Earth’s forested ecosystems. Because fire is a catalyst for change, investigation of post-fire vegetation response is critical to understanding the potential for future conversions from forest to non-forest vegetation types.

Researchers are increasingly examining patterns and drivers of postfire forest recovery amid growing concern that climate change and intensifying fires will trigger ecosystem transformations. Diminished seed availability and postfire drought have emerged as key constraints on conifer recruitment.

An unprecedented conservation effort is underway across 11 western states to address risks to sagebrush ecosystems and the species that depend on them. The sagebrush biome - the largest biome in the Lower 48 states - provides a large diversity of habitats and supports more than 350 species of conservation concern.

A conceptual framework for evaluation of climate effects on tree diseases is presented. Climate can exacerbate tree diseases by favouring pathogen biology, including reproduction and infection processes. Climatic conditions can also cause abiotic disease—direct stress or mortality when trees’ physiological limits are exceeded. When stress is sublethal, weakened trees may subsequently be killed by secondary organisms.

Quantifying fireline effectiveness (FLE) is essential to evaluate the efficiency of large wildfire management strategies to foster institutional learning and improvement in fire management organizations.
