The need for wildlife health surveillance has become increasingly recognized. However, comprehensive programs which cover a wide spectrum of species, pathogens and geographic areas are still lacking in most European countries and practical examples of systems in place remain scarce. This article provides an overview of the organization of wildlife health surveillance in Switzerland, with a focus on the development, current strategies and the activities of the national program carried out by the Centre for Fish and Wildlife Health (FIWI), University of Bern. This documentation may stimulate on-going discussions on the design and development of national wildlife health surveillance programs in other countries. Investigations into wildlife health in Switzerland date back to the 1950s. The FIWI acts as a national competence center for wildlife diseases on mandate of the Swiss federal authorities. The mandate includes four main activities: disease diagnostics, research, consulting and teaching. In line with this, the FIWI has made continuous efforts to strengthen a national network of field partners and implemented strategies to facilitate long-term and metastudies.

In the Tajik National Park (TNP) - a high-altitude area of nearly 26,000 km2 in Central Asia - past and present human activities visibly contrast with standard conservation requirements for protected areas worldwide. This paper focuses on resource management, and highlights three major processes that threaten both the sustainable use of natural resources and the preservation of nature per se: (i) intensified use of biomass as a fuel resource, (ii) inappropriate pasture management, and (iii) increased pressure on endangered wildlife. From analysis of these processes - their historical background, root causes, trends and interrelationships - options and needs to improve park management are proposed and discussed.
