Healthy trees are beneficial to our environment and our property values - but how do we determine if a tree is healthy? This publication briefly discusses common tree health problems and outlines a procedure for assessing tree conditions and getting diagnoses and recommendations from tree health professionals.

Defending homes from fast-spreading high-intensity wildfires is one of the most difficult and dangerous duties for wildland firefighters. Firefighters United for Safety, Ethics, and Ecology (FUSEE) feels strongly that informing homeowners about fire-resistant construction materials will help wildland firefighters better protect communities, and reduce some of the risks to firefighter safety.

Night-time flight searches using night vision goggles have the potential to improve early aerial detection of forest fires, which could in turn improve suppression effectiveness and reduce costs. Two sets of flight trials explored this potential in an operational context.

Comprehensive assessment of ecological change after fires have burned forests and rangelands is important if we are to understand, predict and measure fire effects. We highlight the challenges in effective assessment of fire and burn severity in the field and using both remote sensing and simulation models.

The widespread, native defoliator western spruce budworm (Choristoneura occidentalis Freeman) reduces canopy fuels, which might affect the potential for surface fires to torch (ignite the crowns of individual trees) or crown (spread between tree crowns). However, the effects of defoliation on fire behaviour are poorly understood.

With the potential for worsening fire conditions, discussion is escalating over how to best reduce effects on urban communities. A widely supported strategy is the creation of defensible space immediately surrounding homes and other structures.

A quantitative approach was adopted to explore facets of mindfulness and self-compassion in relation to their ability to predict crewmembers’ perceptions of their supervisors’ leadership capabilities. The sample comprised 43 wildland fire crews consisting of their primary supervisors (n = 43) and crewmembers (n = 246).

We related measurements of annual burned area in the southwest United States during 1984–2013 to records of climate variability. Within forests, annual burned area correlated at least as strongly with spring–summer vapour pressure deficit (VPD) as with 14 other drought-related metrics, including more complex metrics that explicitly represent fuel moisture.

Mechanical mastication is a fuel management technique that disrupts the vertical continuity of forest fuels by shredding of trees and understory vegetation into a highly compacted surface fuel bed.

There is no uniform means for assessing social impact from wildland fires beyond statistics such as home loss, suppression costs and the number of residents evacuated. In this paper we argue for and provide a more comprehensive set of considerations for gauging social impact following wildfires.
