Abalone are herbivorous marine gastropods and are nocturnal – that is, they hide during the day amongst rocks and at night time, they go out in search of food. Its fishery provides a significant source of employment and income to coastal people. From a socio-economic perspective, the long-term sustainability of abalone fisheries is of great importance. Unfortunately, abalone stocks have been overfished in many areas where they are found as a result of ever-increasing market demand, uncontrolled exploitation and/or inadequate or lack of fisheries management. One possible option for resource management is to educate local fishers to develop a corps of local resource managers who would promote sustainable fishing practices and conservation of this valuable resource (see Capinpin, this issue).

The cover shows four species of ferns thriving near the copper-rich soils of the Lepanto mine in Benguet. They are found to absorb the most copper in their roots and thus may be used for phytoremediation (Claveria et al. page 1-12 this issue).
