A 3.6 ha experimental fire was conducted in a black spruce peatland forest that had undergone thinning the year prior. After 50 m of spread natural stand at 35–60 min−1, crown (43,000 kW m−1 intensity using Byram’s method) encountered 50% stem removal treatment; rates treatment were 50–60 min−1. Fuel consumption control (2.75 kg m−2) comparable to (2.35 m−2). Proxy measurements in-stand heat flux sensors as well photogrammetric flame heights detected reductions 30–40% control. Crown fuel...
Mechanical mastication is a fuel management technique that disrupts the vertical continuity of forest fuels by shredding trees and understory vegetation into highly compacted surface bed. Despite increasing application to manage wildfire risk, there little information date on moisture in masticated optimal ignition patterns for prescribed burning. We investigated applicability Fine Fuel Moisture Code (FFMC), component Canadian Fire Weather Index (FWI) System, tracking diurnal day-to-day...
Mechanical mastication is becoming a common fuel management treatment to reduce vertical connectivity, as well crown fire initiation and potential fire-line intensity, but the moisture dynamics of these novel types have been largely unstudied. We recorded concurrent in situ meteorological observations with temperature profiles (at depths 5 13 cm) for masticated beds three treatments lodgepole pine (Pinus contorta Dougl. var. latifolia Engelm.) – black spruce (Picea mariana (Mill.) B.S.P.)...
Wildfire frequency and severity in boreal peatlands can be limited by wet fuel conditions, but increases burn occur when lower water table positions cause drying of fuels. To date, most studies on northern peatland fires have focused ombrotrophic bogs. Though minerotrophic fens are the common type North America, influence structure loading potential fire behaviour is poorly understood. investigate for widespread flame front propagation across fens, we quantified components present three...
Mechanical mastication is increasingly used as a fuel management treatment to reduce fire risk at the wildland–urban interface, although ignition and behaviour in these novel beds are poorly understood. We investigated influence of observed moisture content, wind speed, firebrand size on probability sustained flaming masticated under both laboratory field settings. Logistic regression techniques were applied assess datasets. Models for also developed using estimated from three sets...
Spatial and temporal estimates of burned areas are often used to model greenhouse gas air pollutant emissions from fire events that occur in a region interest over specified time frames. However, behaviour, fuel consumption, severity, ecological effects vary both space when grows across varying fuels topography under different environmental conditions. We developed method for estimating the progression individual wildfires (i.e., day-of-burn) employing ordinary kriging combination...
Key message This document describes a dataset obtained from field sampling program conducted in Alberta, Canada. Field data were used to describe the structure and composition of forest stands, including several fuel loads (e.g., surface, understory, canopy fuels). The can be downloaded https://doi.org/10.17605/OSF.IO/FZ8E4 metadata is available at https://metadata-afs.nancy.inra.fr/geonetwork/srv/fre/catalog.search#/metadata/527efb49-43b4-43eb-88b2-70535ff99fc5 Abstract We present...
The effect of climate change on forest dynamics is likely to increase in importance the forthcoming decades. For this reason, it essential predict extent which changes temperature, precipitation, and atmospheric CO2 might affect development ecosystems successional pathways. gap model ZELIG-CFS was used simulate potential long-term effects species-specific annual mean basal area stand density under two scenarios representative concentration pathways (RCP), 4.5 8.5, for boreal region Ontario,...
This paper presents a set of arguments claiming that construction the quarry near Flamborough, Ontario proposed St. Mary’s Cement Inc. should not be permitted. First, would violate local citizens’ property rights, compromise community health and safety, incur excessive economic costs. Precautionary measures are insufficient, such is expected to irreparably damage drinking water quality life. Second, area for aggregate extraction mostly undeveloped, containing unique, valuable natural...
Although evidence indicates that fire exclusion may result in substantial short- and long-term changes to forest stand structure composition, the effects on eastern white pine (Pinus strobus L.) stands remain largely unknown. We investigated response of trees understory vegetation after prescribed burning a mature northern Ontario, Canada. Results indicate single treatment improved regeneration other mid-shade tolerant species compared controls whereas repeated favoured shade intolerant such...
