Utilizing forest harvest residue is an issue of growing urgency in the British Columbia forest industry, In B.C., forest residues at roadside have traditionally been burned to mitigate fire hazard or, occasionally, they have been left to rot. With an increasing demand for energy and concern over climate change and air quality, burning may no longer be the most desirable practice for dealing with residues. Further, there is an increasing demand for harvest residues by both primary and secondary users to fuel the growing bioeconomy in B.C.
The Bulkley TSA biomass inventory was based on 50-year harvest and road network plans for Crown land provided by the BC Ministry of Forests, Lands and Natural Resource Operations (FLNRO). The biomass yield per hectare predicted for the Bulkley TSA is 25.2 oven-dried tonnes per hectare (odt/ha) from harvest residues. Over the next 50 years a total of 3.48 million odt of available biomass are predicted to be generated by harvest in the Bulkley TSA, or approximately 70,000 odt/yr. Of this, approximately 231,000 odt in total, or 4,600 odt/yr, is expected to be available at the economic price of $60 per oven-dried tonne.
La première ligne de défense contre les blessures à la tête commence par le port du casque protecteur. Par conséquent, il est important de choisir le casque qui convient le mieux au type de tâches effectuées, qu’il soit bien ajusté et qu’il soit confortable, afin d’offrir la meilleure protection. Une comparaison a été effectuée relativement aux caractéristiques et à l’efficacité de divers casques de protection utilisés par les abatteurs.
Timber harvest companies are looking for cost-effective methods for harvesting low value fibre. FPInnovations conducted a multi-faceted research project in the Nazko region to compare several operational aspects of two harvest methods: cut-to-length and conventional.
As part of this research project, FPInnovations’ wildfire group measured and assessed the harvest residue resulting from both harvest methods. With this information, we were able to evaluate potential fire behaviour in each of the harvest areas.
Alberta Agriculture and Forestry asked FPInnovations to evaluate the patented Trident Pump System developed by Younkers Wielding for the system's suitability for wildfire operations. This report summarizes the author's observations and thoughts.
The goal of the project was to develop a new wildland fire sprinkler capable of stream-height adjustment. A Fire Cobra prototype was built base on a design from a team of University of Alberta Mechanical Engineering students. Through field tests, the prototype was inferior and would require additional modifications to become functional.
A modified rainbird sprinkler was tested and it produced 8 m semi-vertical stream. The conclusions reached from the testing included that is possible to use an attachment kit to modify an existing kit sprinkler and farther engineering would be required to provide for a more streamlined kit design capable of sustaining the desired pressure ranges.
Over the course of the project a new industrial sprinkler called the FireBozz was identified in the market place. The legs of FireBozz can be adjusted to change the stream angle height.
Wearable sensors have gained popularity in many industries because they offer a wide range of opportunities for efficiency gains. In reforestation operations, one such way that wearable sensors could improve efficiency is by enabling the creation of detailed maps that show the locations of individual planted seedlings. A planting map with such level of details would benefit foresters, planting supervisors and tree planters by helping them quickly identify missed (unplanted) areas, tree-stashing issues or spacing issues and by providing comprehensive maps of stocking density.
Forest fuels engineering is one of the primary wildfire mitigation strategies advocated by FireSmart™ Canada (Partners in Protection, 2003) and applied by partnering wildfire management agencies and industry operators. Over the past two decades, mechanical forest fuel treatments (including mulching) have been extensively applied in and around communities in the wildland-urban interface to mitigate the risk of wildfire. Fuel managers and fire operations managers would like to better understand how manual and mechanical fuel treatments modify fire behaviour.
Fuel treatment efficacy has been evaluated through post-wildfire case studies (Mooney, 2014; Pritchard et al., 2011), fire behaviour modelling (Fernandes, 2009; Stephens et al., 2009) and subjective expert opinion based approaches (Hayes et al., 2008). The use of experimental fire to evaluate the effectiveness of fuel treatments is limited.
After the advent of mechanization, electrification and robotization, a fourth industrial revolution is upon us: the digital revolution or Industry 4.0. This will be based on the smart factory characterized by an interconnection of machines and systems within production sites, but also between them and the outside world (customers, partners, other production sites)1.
This revolution integrates recent technological developments such as remote machine operation, artificial intelligence, real-time communication, augmented reality, automation, etc.
Après la venue de la mécanisation, de l’électrification et de la robotisation, une quatrième révolution industrielle est à nos portes : la révolution numérique ou l’industrie 4.0. Celle-ci sera fondée sur l’usine intelligente caractérisée par une interconnexion des machines et des systèmes au sein des sites de production, mais aussi entre eux et l’extérieur (clients, partenaires, autres sites de production)1.
Cette révolution intègre les récents développements technologiques tels que le fonctionnement des machines à distance, l’intelligence artificielle, la communication en temps réel, la réalité augmentée, l’automatisation, etc.
