The State Forestry Corporation, hereinafter called Perhutani, has been implementing a program called the Management of Forest Resources with the Community or Pengelolaan Sumberdaya Hutan Bersama Masyarakat (hereinafter called PHBM) since 2001 in an attempt to protect and conserve the existing forest while alleviating poverty. Our research was aimed at examining land cover changes during pre-implementation (1997–1999) and after implementation of the PHBM (1999–2009). Further analysis was conducted to compare forest cover changes in PHBM and non-PHBM villages during 1999–2009. The results show that forest cover decreased during 1997–1999.  However, during 1999–2009, reforestation increased markedly across the entire study area, in both PHBM and non-PHBM villages, although PHBM villages had higher increases in reforestation. Even under population pressure, reforestation was successful in PHBM villages because the people were aware of the current and future benefits of the PHBM, and people realized that the government was acknowledging the property rights of local peoples. The PHBM also provides a secure feeling since the government and the Perhutani program assured the people that the program would be fully implemented.

 The ranging behaviour of translocated problem tigers is poorly understood. The demand for releasing problem tigers back to the wild increases following the increasing the num-ber of problem tigers that needs to be rescued in Sumatra in the last decade. In this study we estimate the home range size and obtain information on daily range of four translocated problem tigers, as well as discussing some potential factors determining the size of home range and their movement. We translocated four adult males Sumatran tigers (Panthera tigris sumatrae) caught after killing domestic animals or rescued from traps set up by villagers for capturing deer and wild boar. The tigers were released fol-lowing 16-225 days rehabilitation. All were fitted with global positioning system collars and released 74-1,350 km from their capture site. The length of time needed by each tiger for establishing home range was between 6 and 13 weeks. The home range size of each individual tiger estimated with 100% minimum convex polygon varies between 67.1 km2 and 400 km2, while estimations with a 95% fixed kernel methods were between 37.5 km2 and 188.1 km2. The difference in home range size established by each translo-cated tigers indicates the variability of the range size even within a subspecies. The maximum distance moved each tiger in one day was different, the range was 8.5-18.9 km. Although preliminary, these data may be useful for improving future translocation of problem tiger, as this study was the first ever conducted in Sumatra.
