An assessment of threats to terrestrial protected areasAbstract Protected areas (PAs) represent a cornerstone of efforts to safeguard biodiversity, and if effective should reduce threats to biodiversity. We present the most comprehensive assessment of threats to terrestrial PAs, based on in situ data from 1,961 PAs across 149 countries, assessed by PA managers and local stakeholders. Unsustainable hunting was the most c... ... hiện toàn bộ

Native Seed Supply and the Restoration Species PoolAbstract Globally, annual expenditure on ecological restoration of degraded areas for habitat improvement and biodiversity conservation is approximately $18bn. Seed farming of native plant species is crucial to meet restoration goals, but may be stymied by the disconnection of academic research in seed science and the lack of effective policies that regulate native ... ... hiện toàn bộ

Managing Natural Capital Stocks for the Provision of Ecosystem ServicesAbstract Decision makers and land managers are increasingly required to manage landscapes for multiple purposes and benefits. However, despite progress in the development of frameworks linking natural capital to the provision of ecosystem services and human benefits there remains little guidance for how management interventions can improve ecosystem service provisio... ... hiện toàn bộ

Eye on the Taiga: Removing Global Policy Impediments to Safeguard the Boreal ForestAbstract The absence of boreal forests from global policy agendas on sustainable development and climate change mitigation represents a massive missed opportunity for environmental protection. The boreal zone contains some of the world's largest pools of terrestrial carbon that, if not safeguarded from a conversion to a net source of greenhouse gases, could seriousl... ... hiện toàn bộ

Shortfalls and Solutions for Meeting National and Global Conservation Area TargetsAbstract Governments have committed to conserving ≥17% of terrestrial and ≥10% of marine environments globally, especially “areas of particular importance for biodiversity” through “ecologically representative” Protected Area (PA) systems or other “area‐based conservation measures”, while individual countries have committed to conserve 3–50% of their land area. We e... ... hiện toàn bộ

Poor ecological representation by an expensive reserve system: Evaluating 35 years of marine protected area expansionAbstract Global areal protection targets have driven a dramatic expansion of the marine protected area (MPA) estate. We analyzed how cost‐effective global MPA expansion has been since the inception of the first global target (set in 1982) in achieving ecoregional representation. By comparing spatial patterns of MPA expansion against optimal MPA estates using the sam... ... hiện toàn bộ

Global priority areas for incorporating land–sea connections in marine conservationAbstract Coastal marine ecosystems rank among the most productive ecosystems on earth but are also highly threatened by the exposure to both ocean‐ and land‐based human activities. Spatially explicit information on the distributions of land‐based impacts is critical for managers to identify where the effects of land‐based activities on ecosystem condition are greate... ... hiện toàn bộ

High Conservation Value or high confusion value? Sustainable agriculture and biodiversity conservation in the tropicsAbstract Green labeling of products that have been produced sustainably is an emerging tool of the environmental movement. A prominent example is the Forest Stewardship Council, which certifies timber that is harvested to manage and maintain forests defined as having High Conservation Value (HCV). The criteria for HCV are now being applied to four rapidly expanding ... ... hiện toàn bộ

Increasing the Scientific Evidence Base in the “High Conservation Value” (HCV) Approach for Biodiversity Conservation in Managed Tropical LandscapesAbstract Land‐use change is a major driver of tropical biodiversity declines. The “High Conservation Value” (HCV) approach aims to protect critical environmental and social values in production landscapes, and is a common feature of many voluntary certification schemes (e.g., Forest Stewardship Council, Roundtable on Sustainable Palm Oil). Despite the popularity of ... ... hiện toàn bộ

The dilemma of green business in tropical forests: how to protect what it cannot identifyAbstract Much tropical biodiversity resides in forests managed by timber, mining, and plantation companies. These companies can determine the local persistence of many species and have considerable implications for global conservation outcomes. Many companies are willing to invest in improved management as long as this does not undermine their business—indeed access... ... hiện toàn bộ
