A dam is being built in Valia-Kalda, one of the ten national parks in Greece, despite the fact that this is not permissible under Greek law. Apart from the destruction caused by this activity, the park suffers from illegal hunting and over-grazing by livestock. The author, who was a member of two expeditions to Valia-Kalda in 1985 and 1986, describes the park, highlighting the features of special interest, and urges the Greek Government to safeguard it.

The Hawaiian archipelago was formerly home to one of the most species-rich land snail faunas (> 752 species), with levels of endemism > 99%. Many native Hawaiian land snail species are now extinct, and the remaining fauna is vulnerable. Unfortunately, lack of information on critical habitat requirements for Hawaiian land snails limits the development of effective conservation strategies. The purpose of this study was to examine the plant host preferences of native arboreal land snails in Puʻu Kukui Watershed, West Maui, Hawaiʻi, and compare these patterns to those from similar studies on the islands of Oʻahu and Hawaiʻi. Concordant with studies on other islands, we found that four species from three diverse families of snails in Puʻu Kukui Watershed had preferences for a few species of understorey plants. These were not the most abundant canopy or mid canopy species, indicating that forests without key understorey plants may not support the few remaining lineages of native snails. Preference for Broussaisia arguta among various island endemic snails across all studies indicates that this species is important for restoration to improve snail habitat. As studies examining host plant preferences are often incongruent with studies examining snail feeding, we suggest that we are in the infancy of defining what constitutes critical habitat for most Hawaiian arboreal snails. However, our results indicate that preserving diverse native plant assemblages, particularly understorey plant species, which facilitate key interactions, is critical to the goal of conserving the remaining threatened snail fauna.

This paper presents the results of surveys conducted in 1994 to establish the population size and density, and conservation status of red howler monkeys Alouatta seniculus insulanus and white-fronted capuchin monkeys Cebus albifrons trinitatis in the Trinity Hills, Bush-Bush and Central Range Wildlife Sanctuaries of the Republic of Trinidad and Tobago, West Indies. Populations of the red howler and capuchin monkey have declined by about 25 per cent in Bush-Bush Wildlife Sanctuary over the past 25 years. This decrease was attributed to intensive hunting pressure and habitat destruction. These factors have also caused monkey population declines in the Trinity Hills and Central Range Wildlife Sanctuaries. Recommendations are presented for the local government to enhance the protection of wild monkeys and their habitats in Trinidad.
