“…Integrated interpretation is common within the OSM, reflected in hundreds of published research papers, each including, at minimum, the contextualization of results with previous findings (e.g., Landis et al, 2019) and synthesis of results (Davidson et al, 2020). OSM researchers have also published some review papers (e.g., Harner et al, 2018).…”

Although challenging to develop and operate, some degree of integrated monitoring is often necessary, especially at regional scales, to address the complex questions of environmental management and regulation. The concept of integration is well-understood, but its practice across programs and studies can be diverse suggesting a broader examination of the existing general approaches is needed. From the literature, we suggest integration of monitoring can occur across three study components: interpretation, analysis, and design. Design can be further subdivided into partial and full integration. Respectively combining information, data, and designs, we further define these types of integration and describe their general benefits and challenges, such as strength of inference. We further use the Oil Sands Monitoring program in northern Alberta as an example to clarify the practices common among integrated monitoring programs. The goal of the discussion paper is to familiarize readers with the diverse practices of integrated monitoring to further clarify the various configurations used to achieve the wider goals of a program.

“…In contrast to within-themes, few examples of partially integrated designs are available which cross themes in OSM, but forest health is a prime example (e.g., Davidson et al, 2020). Expanding this approach to other studies within OSM has long been a goal (Dowdeswell et al, 2010).…”

“…Typical symptoms include disturbances in photosynthesis and stomatal conductance, shifts in carbon dioxide allocation and water use efficiency, and leaf loss. The mechanism and effects of the impact of toxic chemicals on the course of physiological processes in plants have been described in numerous studies [12][13][14][15][16][17][18]. Additionally, the deposition of pollutants influences the way in which trees respond to other abiotic and biotic stressors, an example being increased sensitivity to drought and pathogen attacks [19].…”

“…To assess the pollution stress in trees, many biochemical, physiological, and morphological methods are used [14][15][16][17][18][19]26]. Among the morphological methods, the most common approach is tree-ring analysis [27][28][29][30][31][32][33][34][35].…”

“…The most severe damage affected forests growing in areas having a high concentration of industrial plants and subjected to the long-term negative influence of various toxic substances. This problem Despite the significant changes that have occurred over the recent decades in the chemistry, concentration, and geographical distribution of air pollutants (reduction in SOX emissions by 80% and NOX emissions by 30%), the influence of these pollutants on the structure and functioning of forest ecosystems is still visible [3,6,16,18,19,23,24]. A significant proportion of forest ecosystems remain at risk due to the excessive deposition of nitrogen compounds (ammonia NH3) and nitrogen oxides (NOX) [3,17,[23][24][25].…”

The aim of this study was to evaluate Scots pine stand degradation caused by the pollutants emitted from Zakłądy Azotowe Puławy, one of the biggest polluters of the environment in Poland for over 25 years (1966–1990). To assess the pollution stress in trees, we chose the dendrochronological analysis We outlined three directions for our research: (i) the spatio-temporal distribution of the growth response of trees to the stress associated with air pollution; (ii) the direct and indirect effects of air pollution which may have influenced the growth response of trees; and (iii) the role of local factors, both environmental and technological, in shaping the growth response of trees. Eight Scots pine stands were selected for study, seven plots located in different damage zones and a reference plot in an undamaged stand. We found that pollutant emission caused disturbances of incremental dynamics and long-term strong reduction of growth. A significant decrease in growth was observed for the majority of investigated trees (75%) from 1966 (start of factory) to the end of the 1990s. The zone of destruction extended primarily in easterly and southern directions, from the pollution source, associated with the prevailing winds of the region. At the end of the 1990s, the decreasing trend stopped and the wider tree-rings could be observed. This situation was related to a radical reduction in ammonia emissions and an improvement in environmental conditions. However, the growth of damaged trees due to the weakened health condition is lower than the growth of Scots pine on the reference plot and trees are more sensitive to stressful climatic conditions, especially to drought.

This article is part of the special series "A Decade of Research and Monitoring in the Oil Sands Region of Alberta, Canada." The series documents the history of monitoring in the region and critically reviews a synthesis of monitoring results published within key environmental theme areas to identify patterns of consistent responses or effects; significant gaps in knowledge; and recommendations for improved monitoring, assessment, and management of the region.
