Video Regenerative Agriculture: No-Till Farming
Gabe Brown, legendary Rancher from Bismarck, North Dakota, discusses how Regenerative Agriculture is a solution to local and global challenges.

Coastal resilience is an increasingly important topic as impacts from climate change such as accelerated sea level rise and enhanced storm intensity gain prominence. The Disaster Relief Appropriations Act of 2013, which was motivated by Hurricane Sandy related damage, supported many projects throughout the affected region, including the projects found in the following pages.

Video Climate Change's Growing Threat to Public Lands
Secretary Jewell attended the 2014 World Parks Congress in Australia, where she stressed the need for international cooperation on public lands and the growing threat of climate change.

Video Octet Stream Salamanders - The Hidden Jewels of Appalachia
If you want to hit paydirt the Appalachian region is the world’s salamander El Dorado—home to over 70 salamander species. The Appalachian region of the eastern United States is the world's epicenter for salamander biodiversity.

Video application/x-troff-me “One Stick at a Time” in pursuit of climate adaptations for a more sustainable future
This film follows land managers in the Methow Valley, Washington for over a year, from forests to rivers, from fires to snowfall, from beaver capture to release as they try to come to grips with the impacts of climate change and the possible adaptation options right in front of them. It is a conversation starter for answering the question "What can I do?" With support from the best climate experts in the Northwest, it is a chance for each of us to think about what our landscapes will be like ten decades from now. It is a nudge to start today to make our surroundings better than they would be if we did nothing. The film was conceived as part of the 10 Decades Project, the goal of which is to inspire thousands of us to take measurable, concrete steps for climate adaptation in every area for which we are responsible.

Climate Change Vulnerability
New climate change vulnerability assessments for 41 species and 3 habitats in the Appalachians are now available. The conservation community can view and search each of these assessments by vulnerability scores, conservation status ranks, state and subregion of assessment, and higher taxonomy. In addition, principle investigators NatureServe compiled the results of 700 species assessments previously completed by other researchers as well as assessments on several habitats.

File Troff document South-Central Interior Small Stream and Riparian Habitat
This habitat was assessed in both the Cumberland - Southern Appalachian subregion and the Interior Low Plateau subregion. Results are in the first two tabs of the spreadsheet. A description of the habitat, and a list of associated species, is included in the description tab. The remaining tabs describe the individual factors and their definitions. These results are in the review stage. Please send comments to lesley_sneddon@natureserve.org.

File PDF document Analysis of monotonic greening and browning trends from global NDVI time-series
Remotely sensed vegetation indices are widely used to detect greening and browning trends; especially the global coverage of time-series normalized difference vegetation index (NDVI) data which are available from 1981. Seasonality and serial auto-correlation in the data have previously been dealt with by integrating the data to annual values; as an alternative to reducing the temporal resolution, we apply harmonic analyses and non-parametric trend tests to the GIMMS NDVI dataset (1981–2006). Using the complete dataset, greening and browning trends were analyzed using a linear model corrected for seasonality by subtracting the seasonal component, and a seasonal non-parametric model. In a third approach, phenological shift and variation in length of growing season were accounted for by analyzing the time-series using vegetation development stages rather than calendar days. Results differed substantially between the models, even though the input data were the same. Prominent regional greening trends identified by several other studies were confirmed but the models were inconsistent in areas with weak trends. The linear model using data corrected for seasonality showed similar trend slopes to those described in previous work using linear models on yearly mean values. The non-parametric models demonstrated the significant influence of variations in phenology; accounting for these variations should yield more robust trend analyses and better understanding of vegetation trends.

File PDF document Afforestation Effects on Soil Carbon Storage in the United States: A Synthesis
Afforestation (tree establishment on nonforested land) is a management option for increasing terrestrial C sequestration and mitigating rising atmo- spheric carbon dioxide because, compared to nonforested land uses, afforestation increases C storage in aboveground pools. However, because terrestrial ecosystems typically store most of their C in soils, afforestation impacts on soil organic carbon (SOC) storage are critical components of eco- system C budgets. We applied synthesis methods to identify the magnitude and drivers of afforestation impacts on SOC, and the temporal and verti- cal distributions of SOC change during afforestation in the United States. Meta-analysis of 39 papers from 1957 to 2010 indicated that previous land use drives afforestation impacts on SOC in mineral soils (overall average = +21%), but mined and other industrial lands (+173%) and wildlands (+31%) were the only groups that specifically showed categorically significant increases. Temporal patterns of SOC increase were statistically significant on former industrial and agricultural lands (assessed by continuous meta- analysis), and suggested that meaningful SOC increases require ≥15 and 30 yr of afforestation, respectively. Meta-analysis of 13C data demonstrated the greatest SOC changes occur at the surface soil of the profile, although par- tial replacement of C stocks derived from previous land uses was frequently detectable below 1 m. A geospatial analysis of 409 profiles from the National Soil Carbon Network database supported 13C meta-analysis results, indicating that transition from cultivation to forest increased A horizon SOC by 32%. In sum, our findings demonstrate that afforestation has significant, positive effects on SOC sequestration in the United States, although these effects require decades to manifest and primarily occur in the uppermost (and per- haps most vulnerable) portion of the mineral soil profile. Abbreviations: BD, bulk density; CI, confidence interval; MAP, mean annual precipitation; MAT, mean annual temperature; SOC, soil organic carbon.

File PDF document A global overview of drought and heat-induced tree mortality reveals emerging climate change risks for forests
Of particular concern are potential increases in tree mortality associated with climate- induced physiological stress and interactions with other climate-mediated processes such as insect outbreaks and wildfire. Despite this risk, existing projections of tree mortality are based on models that lack functionally realistic mortality mechanisms, and there has been no attempt to track observations of climate-driven tree mortality globally. Here we present the first global assessment of recent tree mortality attributed to drought and heat stress. Although episodic mortality occurs in the absence of climate change, studies compiled here suggest that at least some of the world’s forested ecosystems already may be responding to climate change and raise concern that forests may become increasingly vulnerable to higher background tree mortality rates and die-off in response to future warming and drought, even in environments that are not normally considered water-limited. This further suggests risks to ecosystem services, including the loss of sequestered forest carbon and associated atmospheric feedbacks. Our review also identifies key information gaps and scientific uncertainties that currently hinder our ability to predict tree mortality in response to climate change and emphasizes the need for a globally coordinated observation system. Overall, our review reveals the potential for amplified tree mortality due to drought and heat in forests worldwide. heat, temperature, drought, tree mortality, forest dieoff
