Man et al (2013) also reported that reduced harvest levels stored significantly more carbon over the 100-year planning horizon as compared to strategies that focused on tree growth rates (Johnson et al 2009). Similar conclusions have also been drawn from boreal forests (Garcia-Gonzalo et al 2007, Man et al 2013, Europe (Fortin et al 2012), and Chile (Swanson 2009), Australia (Ranatunga et al 2008), and other regions.…”

“…A particular challenge, in this regard, is to seek site-specific management options because of the variations among ecosystem types and between the regions and their importance at different temporal scales (e.g., short-term vs. longterm values - Lafortezza et al 2008). Stimulated by these needs, numerous large-scale experiments in the United States (Chen et al 2014) and elsewhere (Garcia-Gonzalo et al 2007, Ranatunga et al 2008, Fortin et al 2012, Man et al 2013) were initiated to manipulate ecosystem structures and compositions. These experiments, unlike conventional approaches in forestry and ecology (Sheriff & He 1997), were designed to mimic natural and human disturbances at large spatial scales and to quantify the ecological responses with sound controls of the manipulations and statistical confidence (i.e., random block design with at least three replications).…”

, ranging from 1.60 to 1.94 Mg ha -1 yr -1 at the NHM plots. Changes in the net AGB growth rate were contributed by different growth rates of live trees and mortality and exhibited clear intra-annual variation during the five sampling periods. We observed a decreasing contribution of Quercus velutina (black oak) AGB (~6%), an increasing trend for Q. alba (white oak), and a stable change for Q. coccinea (scarlet oak) during the study period.

“…Harvest reduction strategies have a higher potential for producing Carbon credits in the short term (25 to 50 years). Man et al (2013) found little difference in the number of Carbon credits produced between different harvest reduction strategies, and suggested that reducing the harvest level to a fixed target below the baseline provides the forest manager with more flexibility. Strategies to increase forest growth rates above the baseline levels include fertilization and planting genetically improved stock; however, these strategies store significantly less Carbon than the harvest reduction strategies (Man et al, 2013) and pose the risk of not being able to deliver the projected growth increase.…”

This paper uses the inventory of three actively managed forest estates located in the Coastal, Central Interior, and Northern Interior forest regions in British Columbia to estimate the cost to produce Carbon credits ($ per Carbon credit) when the harvest is reduced below the baseline level. The financial analysis was conducted over a range of discount rates (0-16%) and the total cost included the opportunity cost due to harvest reduction and the Carbon project cost (the Carbon project initial establishment and validation cost and the ongoing verification cost for two frequencies (1-year and 5-year)). When the opportunity cost was not included, the cost per Carbon credit was similar to previous findings (lower cost per Carbon credit for higher site index (i.e. top height in meters at age 50)). However, when the opportunity cost was included the cost per Carbon credit was higher for higher site indices which corresponded to higher average value per hectare harvested (AVHH) (i.e. timber revenue multiplied by average harvested volume per hectare per year). The reversal of trends is the result of the average timber revenue being higher for higher site indices which resulted in a higher opportunity cost and higher AVHH. The opportunity cost represented 58% to 97% of the cost per Carbon credit. Compared to the 5-year verification, the 1-year verification frequency increased the total cost per Carbon credit by 1% to 22%, with the smallest increase being when the Carbon project cost represented a small percent of the total cost. The estimates for the three forest estates analyzed here represent three points from a larger spectrum, and they identify the cost per Carbon credit over a range of site indices (14.7 to 25.6 meters top height at age 50), AVHH (12.2 to 63.7 thousand $ ha −1 year −1 ), and timber net revenues ($4 to $35 m −3 ). Further research is required to determine if the trends found in this study hold over a more densely populated spectrum.

Forests in and around the cities are becoming crucial in climate adaptation as the severity and frequency of heat waves, and urban heat islands are estimated to increase in the coming decades. As the local forestry authority, the forest district manager's role in establishing and managing forested green spaces in and around the cities is essential. The study is based on a land cover analysis, in selected provinces of Türkiye, for a period of three decades. We compared the responses of district forest managers to understand their awareness and perception of urban green areas and related climate change issues. The survey was sent to all district forest managers of the State Forest Service (GDF) and responded to by 69 from 28 provinces. The major land cover maps used were explicitly developed for land cover analysis by the GDF with temporal points of 1990, 2000, and 2015. To calculate the urban forest cover in the city centers, we used the city limit delineation shape les produced by the EU Copernicus program. We also employed the land consumption rate/population growth rate metric to reveal and discuss the provinces' land and forest cover changes. The results showed that forest district managers were aware of the general condition of the forests in their provinces. Still, there was a considerable inconsistency between actual land use changes (i.e., deforestation) and their responses. The study also revealed that the forest managers were aware of the increasing in uence of climate change issues but were not knowledgeable enough to establish the connection between their tasks and climate change. It has been concluded that the national forestry policy should prioritize the urban-forest interaction and develop the capacities of district forest managers to improve the e ciency of climate policies on a regional scale.
