Bright Spots of Carbon Storage in Temperate Forests - Dataset
<p>This dataset accompanies the publication 'Bright Spots of Carbon Storage in Temperate Forests' in the Journal of Applied Ecology.</p> <p>1. Mitigating climate change is an urgent challenge for society. Increasing carbon storage in forests, which cover more than 30% of the global land surface, presents a key opportunity to meet this challenge. Although the biophysical and ecological factors that affect carbon storage have been well studied, the relative importance of social factors in privately owned forests, such as people’s goals and management actions, is less well understood.</p> <p>2. We examine how well typical biophysical and ecological variables can explain differences in aboveground carbon storage across 1561 plots in temperate forests of southern Quebec, Canada. We then identify bright spots and dark spots of aboveground carbon storage, where forests are performing much better or worse than predicted based on biophysical and ecological conditions alone. We conducted surveys with forest owners to assess whether their individual goals, values, and management actions explain the differences in carbon storage between bright and dark spots.</p> <p>3. Biophysical and ecological variables collectively explained a substantial fraction of the variation in carbon storage between forest plots (R<sup>2 </sup>= 0.42). The ecological variables of stand age, species richness, and functional diversity within the plots were the most important variables in explaining carbon storage.</p> <p>4. Surveys with forest owners showed that bright spots (plots that stored more carbon than predicted) were often associated with a strong connection to, or dependence on, the forest property. Dark spots were more often associated with forest harvesting and hunting.</p> <p>5. <em>Synthesis and applications</em>: Ecologically-based policies that aim to increase the average forest age, species richness, and functional diversity—and socially-based policies that incentivise long-term forest ownership, stronger connections between people and their properties, and maple syrup production—could help increase carbon storage over multidecadal timescales and thereby reduce the harmful effects of climate change.</p>
Pairing functional connectivity with population dynamics to prioritize corridors for Southern California spotted owls
<p><strong>Aim:</strong> Land use change, climate change, and shifts to disturbance regimes make successful wildlife management challenging, particularly when ongoing urbanization constrains habitat and movement. Preserving and maintaining landscape connectivity is a potential strategy to support wildlife responding to these stressors. Using a novel model framework, we determined the population-level benefit of a set of identified potential corridors for spotted owl population viability.</p> <p><strong>Location:</strong> Southern California, United States.</p> <p><strong>Methods:</strong> Combining habitat suitability and dynamic metapopulation models, we compared the benefit of corridors to the Southern California spotted owl population, measured as the increase in the expected minimum abundance, both now and under a future climate. Our approach considered key corridor characteristics important to conservation decisions, namely, corridor irreplaceability and local population network benefit.</p> <p><strong>Results:</strong> We identified two corridors likely to increase Southern California spotted owl expected minimum abundance under current climate conditions. At the regional scale, of the 16 corridors evaluated, one corridor was irreplaceable (i.e. no other corridors in the network could provide a similar increase in abundance when the irreplaceable corridor was removed) and one corridor was identified as redundant (i.e. remaining corridors in the network can provide some of the increases in abundance offered by the removed corridor). Both putative corridors connected two large, populous, and similarly-sized patches. Additionally, we identified two more corridors at the local scale. We found that, under climate change, population declines may limit the benefit of connectivity for a range-restricted species like the spotted owl.</p> <p><strong>Main Conclusions:</strong> Our analytical approach highlights important criteria for corridor identification and prioritization, namely, irreplaceability versus redundancy, local versus regional benefit, and corridor impact in a changing landscape. With the capability of incorporating estimated functional connectivity into population dynamics, our modeling framework advances connectivity decision making for other species of conservation concern and archetypal taxa within ecological communities.</p>
