“…On a national level, Guatemala retains one of the highest deforestation rates in the Western Hemisphere (Hansen et al 2013), and the highest rate of protected area degradation in the Americas (Leisher et al 2013). By comparison, deforestation rates in certified forest concessions are relatively low (Hodgdon et al 2015).…”

The jaguar Panthera onca requires large areas of relatively intact habitats containing adequate amounts of prey to survive. Since a substantial portion of jaguar range occurs outside of strict protected areas, there is a need for economic incentives for habitat conservation, which carefully managed selective logging can provide. Forest Stewardship Council and Pan European Forest Council certifications intended to regulate wood extraction to maintain the ecological functions of forests require evidence of biodiversity and ecosystem conservation. We draw on twelve surveys across four countries and a range of biomes to present evidence that adequate logging management can maintain jaguar populations, but that they are at risk without efficient control of secondary impacts of access and hunting. Where resident, the presence of jaguars can serve as an indication that the ecological requirements of certified timber extraction are being met. We present a gradient of rigor for monitoring, recommending cost-effective options.

Abstract:In the Brazilian Amazon, multiple logging activities are undergoing, involving different actors and interests. They shape a disturbance gradient bound to the intensity and frequency of logging, and forest management techniques. However, until now, few studies have been carried out at the landscape scale taking into account these multiple types of logging and this disturbance gradient. Here we address this issue of how to account for the multiple logging activities shaping the current forest landscape. We developed an inexpensive and efficient remote sensing methodology based on Landsat imagery to detect and track logging activity based on the monitoring of canopy openings. Then, we implemented a set of remote sensing indicators to follow the different trajectories of forest disturbance through time. Using these indicators, we emphasized five major spatial and temporal disturbance patterns occurring in the municipality of Paragominas (State of Pará, Brazilian Amazon), from well-managed forests to highly over-logged forests. Our disturbance indicators provide observable evidence for the difference between legal and illegal patterns, with some illegal areas having suffered more than three explorations in fifteen years. They also clearly underlined the efficiency of Reduced Impact Logging (RIL) techniques applied under Forest Stewardship Council (FSC) guidelines to reduce the logging impacts in terms of canopy openings. For these reasons, we argue the need to promote legal certified logging to conserve forests, as without them, many actors mine the forest resources without any concerns for future stocks. Finally, our remote tracking methodology, which produces easy to interpret disturbance indicators, could be a real boon to forest managers, including for conservationists working in protected areas and stakeholders dealing with international trade rules such as RBUE (Wood regulation of European Union) or FLEGT (Forest Law for Enforcement, Governance and Trade).

“…A study across 49 protected areas in 22 countries found protected area category to be insignificant in predicting amount of land clearing [49]. Analysis of 1788 protected areas in Latin America found category V protected areas around the median of all categories in terms of vegetation loss [50]. Joppa et al [51] looking at natural vegetation cover in protected areas found little difference between different categories, except in West Africa where categories V and VI performed less well than stricter forms of protection.…”

A growing number of protected areas are defined by the International Union for Conservation of Nature (IUCN) as protected landscapes and seascapes, or category V protected areas, one of six protected area categories based on management approach. Category V now makes up over half the protected area coverage in Europe, for instance. While the earliest category V areas were designated mainly for their landscape and recreational values, they are increasingly expected also to protect biodiversity. Critics have claimed that they fail to conserve enough biodiversity. The current paper addresses this question by reviewing available evidence for the effectiveness of category V in protecting wild biodiversity by drawing on published information and a set of case studies. Research to date focuses more frequently on changes in vegetation cover than on species, and results are limited and contradictory, suggesting variously that category V protected areas are better than, worse than or the same as more strictly protected categories in terms of conserving biodiversity. This may indicate that differences are not dramatic, or that effectiveness depends on many factors. The need for greater research in this area is highlighted. Research gaps include: (i) comparative studies of conservation success inside and outside category V protected areas; (ii) the contribution that small, strictly protected areas make to the conservation success of surrounding, less strictly protected areas-and vice versa; (iii) the effectiveness of different governance approaches in category V; (iv) a clearer understanding of the impacts of zoning in a protected area; and (v) better understanding of how to implement landscape approaches in and around category V protected areas.
