While improved management of agricultural landscapes is promoted as a promising natural climate solution, available estimates of the mitigation potential are based on coarse assessments of both agricultural extent and aboveground carbon density. Here we combine 30 meter resolution global maps of aboveground woody carbon, tree cover, and cropland extent, as well as a 1 km resolution map of global pasture land, to estimate the c...
Where is the residual terrestrial carbon sink?NARA Subscribed
The apparent accumulation of carbon on land necessary to balance the global carbon budget has perplexed scientists since the first carbon budgets were constructed more than 40 years ago. The magnitude of the sink over the decade 2006–2015 averaged 3.1 ± 0.9 PgC/year, but neither the factors causing it nor its location are known. Here, based on results from a recent analysis by Baccini et al. ( ), we estimate that about a third...
Halving carbon emissions from tropical deforestation by 2020 could help bring the international community closer to the agreed goal of NYDF ). We assemble and refine a robust dataset to establish a 2001–2013 benchmark for average annual carbon emissions from gross tropical deforestation at 2.270 Gt CO 2 yr −1 . Brazil did not sign the NYDF , yet from 2001 to 2013, Brazil ranks first for both carbon emissions from gross tropica...
The potential ecological costs and cobenefits of REDD: a critical review and case study from the Amazon regionNARA Subscribed
The United Nations climate treaty may soon include a mechanism for compensating tropical nations that succeed in reducing carbon emissions from deforestation and forest degradation, source of nearly one fifth of global carbon emissions. We review the potential for this mechanism [reducing emissions from deforestation and degradation (REDD)] to provoke ecological damages and promote ecological cobenefits. Nations could potentia...
Landscape Ecosystems of Northern Lower Michigan and the Occurrence and Management of the Kirtland's WarblerNARA Subscribed
The Kirtland's warbler (Dendroica kirtlandii Baird) is an endangered songbird that nests in northern Lower Michigan in ecosystems dominated by young jack pine (Pinus banksiana Lamb.). An ecological, multifactor approach was used to determine the range and characteristics of landform-level ecosystems supporting the warbler and to compare the spatial and temporal patterns of warbler occupation among these ecosystems. Using an ec...
Landscape Ecosystems of the Mack Lake Burn, Northern Lower Michigan, and the Occurrence of the Kirtland's WarblerNARA Subscribed
The Kirtland's warbler (Dendroica kirtlandii Baird) is a federally endangered songbird that nests only in ecosystems dominated by young jack pine (Pinus banksiana Lamb.) in northern Michigan. Although considerable research has focused on the bird, comparatively little information is available on the specific landscape ecosystems occupied by the warbler. The 9,700 ha Mack Lake burn provided an opportunity to track the pattern o...
