A model for improving endangered species recovery programs

This paper discusses common organizational problems that cause inadequate planning and implementation processes of endangered species recovery across biologically dissimilar species. If these problems occur, even proven biological conservation techniques are jeopardized. We propose a solution that requires accountability in all phases of the restoration process and is based on cooperative input among government agencies, nongovernmental conservation organizations, and the academic community. The first step is formation of a task-oriented recovery team that integrates the best expertise into the planning process. This interdisciplinary team should be composed of people whose skills directly address issues critical for recovery. Once goals and procedures are established, the responsible agency (for example, in the United States, the US Fish and Wildlife Service) could divest some or all of its obligation for implementing the plan, yet still maintain oversight by holding implementing entities contractually accountable. Regular, periodic outside review and public documentation of the recovery team, lead agency, and the accomplishments of implementing bodies would permit evaluation necessary to improve performance. Increased cooperation among agency and nongovernmental organizations provided by this model promises a more efficient use of limited resources toward the conservation of biodiversity.     

A longitudinal study of the links between Local Air Quality Management and Local Transport Planning policy processes in England

The second round of the Local Transport Plan (LTP2) process in England presents unique challenges and opportunities for integrating Local Air Quality Management (LAQM) within current transport planning policy. Using content analysis of LTP2 documents from nine English authorities, and results from a questionnaire survey of local government officers undertaken in late 2007, this paper charts the changes in the integration of air quality management within the transport planning process since 1997. While substantial improvements in policy integration were observed within the selected case studies, the paper demonstrates that such improvements are often constrained by institutional complexities that create implementation gaps between national objectives and local decision-making outcomes.

Artisanal fishing and coastal conservation in West Africa

Artisanal fishing is an activity which has long occupied an important place on the West African coast. In less than 20 years, the increasingly widespread use of motors in fishing boats and cold storage facilities both on board and on land have enabled fishermen to master the constraints of space and time. Furthermore, globalization has created a demand for new products, thus influencing the behaviour of fishermen and consequently the status of some fish, turtle and marine mammal species. Development policies for artisanal fishing do not adequately reflect the importance of these changes. They tend to use inappropriate scales of reference, be it spatially (national borders take precedence over ecosystems) or temporally (the long-term consequences of development plans are seldom considered). Some international conservation organizations are testing promising new approaches to managing resources more sustainably and restoring degraded ecosystems, and their recent experiences can serve as useful examples to others. It is recommended to grant special rights of access to resident fishermen. In defending ‘their’ resources, they will also protect the ecological functions of the area. Close collaboration with administrations and development assistance agencies is needed to assess consequences of political decisions on the use of resources. The important role of marine protected areas as a tool for fishing management should be better documented and strengthened. These areas should not be considered as isolated units but rather as vital parts of a comprehensive system for improved coastal zone management. Consistent with the ecosystem approach, fishermen and their communities, being the main users of coastal resources, should also play a major role in the design and implementation of any fishing management actions.     

Grasshopper assemblage response to conservation ecological networks in a timber plantation matrix

Grasshopper assemblages are well known to be sensitive and responsive to changes occurring in habitats, enabling their application as bioindicators. Large-scale ecological networks (ENs) have been proposed as a conservation mitigation measure, and are used extensively in southern Africa to offset the impacts on biodiversity of commercial afforestation. Here, grasshopper response to an EN of 15 semi-natural grassland sites embedded in an exotic timber plantation matrix was investigated over two time periods, one year apart. The aim was to determine which environmental variables had a significant effect on grasshoppers, whether this response was robust among seasons, and the extent of phylogenetic variability in the response. The results showed that grasshopper species responded strongly and consistently to area of the site, time lapse since the last fire, and inconsistently to proportion of short grasses. Generalized least squares models with phylogenetic adjustment showed that there was a strong phylogenetic signal in species response to habitat quality, illustrating that site occupancy patterns were distinct for species from different subfamilies. Since grasshopper assemblages are more sensitive to internal patch-level environmental factors of ENs than to patch isolation, ENs may indeed be a suitable mitigation measure, although effectiveness is expected to vary among taxa.
