Abstract
Based on the data from this study and a literature review, there are two distinct trajectories for hemlock wood moisture content, depending on if the tree was felled before or after May. Hemlock trees felled before May gain the full benefit of spring drying according to the ambient conditions of their local micro-climate. Trees felled after May suffer from a physiological spike in moisture content that the tree generates to promote its growth and survive the summer soil drought.

Abstract
The problem of second-growth western hemlock (Tsuga heterophylla) sinking when watered continues to plague the coastal logging industry of British Columbia. A study conducted by FPInnovations in 2015-16 concluded that felled hemlock logs took two distinct trajectories in their drying patterns through time, depending on whether they were felled before or after May.

Abstract
The effects of natural drying in relation to the use of tarps on the moisture content of stacked softwood roundwood were examined. Biomass quality logs were stored for a period of 15 months in a mill yard in the Bas Saint-Laurent region of Quebec. The results of the study showed that the roundwood dried naturally during the summer season with moisture content at the end of the season below 30%. Tarping the roundwood piles during the fall and winter prevented an average increase in moisture content of 6%.
Abstract
Cette étude d'entreposage de la biomasse forestière visait à évaluer les effets du séchage naturel par rapport à l'utilisation de bâches sur la teneur en humidité de bois rond résineux au cours d'une période de 15 mois. Des billes de qualité biomasse ont été empilées dans un parc d'usine de la région du Bas-Saint-Laurent, au Québec. Les résultats de l'étude ont démontré que la biomasse séchait très bien naturellement pendant l'été avec un taux d'humidité en fin de la saison estivale en-dessous de 30%. La bâchage des empilements de biomasse au cours de l'automne et de l'hiver a permis d'éviter une augmentation moyenne du taux d'humidité de 6 %.

Abstract
FPInnovations performed short-term productivity studies on a road rehabilitation operation that utilized a Kobelco ED150 BladeRunner. The BladeRunner is a multi-purpose machine that can function as an excavator and a bulldozer, due to its front blade attachment. Productivity studies were also performed on an excavator (John Deere 200C) and bulldozer (Caterpillar D6M) team that performed the same work as the BladeRunner.

Abstract
The idea that a wicking treatment – leaving tops, branches, and needles attached to the stem after felling – would reduce stem moisture content and lead to reduced loss of western hemlock logs from sinking during watering was tested. This study did not show that wicking produces a different result from normal bucking in average stem moisture content if both groups are treated equally. Further, after curing for two months logs did not increase in moisture content during watering.
