The effort included developing a map of bioclimates with 12 bioclimate zones, a map of biogeographic provinces with Alaska-Yukon and Aleutian provinces, and a map of geographic sectors with six sectors that provided the basis for classification of boreal vegetation. Vegetation mapping was done at 1:7.5 million scale using the mapping protocols of the CBVM team. Mapping used MODIS imagery as the basis for manual image interpretation and an integrated-terrain-unit approach, which included classifications for bioclimate, physiography, generalized geology, permafrost, disturbance, growth from, geographic sector, and vegetation. Vegetation was mapped at two hierarchical levels: (1) formation group differentiating zonal and azonal systems; and (2) geographic sectors based on bioclimatic zonation and dominant species that characterize broad longitudinal regions or biogeographic provinces. Each of the 19 map units was described by identifying the dominant and characteristic species and its climatic and landscape characteristics, as well as references that relate to the unit.

The Circumpolar Biodiversity Monitoring Program, a cornerstone programme of the Conservation of Arctic Flora and Fauna (CAFF), Arctic Council working Group is an international network of scientists, government agencies, Indigenous organizations and conservation groups working together to harmonize and integrate efforts to monitor the Arctic's living resources.CBMP experts are developing four coordinated and integrated Arctic Biodiversity Monitoring Plans to help guide circumpolar monitoring efforts. Results will be channeled into effective conservation, mitigation and adaptation policies supporting the Arctic. These plans represent the Arctic's major ecosystems(Marine, Freshwater, Coastal, Terrestrial). It is important that monitoring programs develop the most effective reporting strategies if they are to inform decision making. To facilitate effective and consistent reporting, the CBMP has chosen a suite of indices and indicators that provide a comprehensive picture of the state of Arctic biodiversity – from species to habitats to ecosystem processes to ecological services. These indices and indicators are developed in a hierarchical manner, allowing users to drill down into the data from the higher-order indices to more detailed indicators. These are being developed through an expert consultation process. The Arctic Species Trend Index (ASTI) is part of this suite of indicators and indices developed by CAFFs CBMP. It tracks trends in over 300 Arctic vertebrate species and comprises the Arctic component of the Living Planet Index. It is important to identify how wildlife and ecosystems are changing in order to develop effective conservation and adaptation strategies in the Arctic, an environment undergoing dramatic changes. The ASTI describes overall trends across species, taxonomy, ecosystems, regions and other categories.

The Snow Covered Area product is based on a Normalized Difference Snow Index(NDSI), which is similar to NDVI, but exploits different bands in the equation (Equation 3),namely Green (Band 4) and Short Wavelength Near-infrared (SWNIR, Band 6). It isimportant to note that the Band 6 sensor on MODIS Aqua malfunctioned shortly after launch,so Snow Covered Area from the Aqua sensor is calculated using Bands 3 and 7. This mayintroduce errors in identifying snow in vegetated areas, as the use of Band 7 results in falsesnow detection. For this reason the MODIS Terra product has been provided for the CAFF-system.

Extensive oil and gas activity has occurred in the Arctic, primarily land-based, with Russia extracting 80% of the oil and 99% of the gas to date (AMAP 2008). Furthermore, the Arctic still contains large petroleum hydrocarbon reserves and potentially holds one fifth of the world’s yet undiscovered resources, according to the US Geological Survey (USGS 2008) (Fig. 14.4). While much of the currently known Arctic oil and gas reserves are in Russia (75% of oil and 90% of gas; AMAP 2008), more than half of the estimated undiscovered Arctic oil reserves are in Alaska (offshore and onshore), the Amerasian Basin (offshore north of the Beaufort Sea) and in W and E Greenland (offshore). More than 70% of the Arctic undiscovered natural gas is estimated to be located in the W Siberian Basin (Yamal Peninsula and offshore in the Kara Sea), the E Barents Basin and in Alaska (offshore and onshore) (AMSA 2009). Associated with future exploration and development, each of these regions would require vastly expanded Arctic marine operations, and several regions such as offshore Greenland would require fully developed Arctic marine transport systems to carry hydrocarbons to global markets. In this context, regions of high interest for economic development face cumulative environmental pressure from anthropogenic activities such as hydrocarbon exploitation locally, together with global changes associated with climatic and oceanographic trends.
