This proceedings is a compilation of 33 papers that were presented at the regional meetings of the forest and conservation nursery associations in the United States in 2002. The joint meeting of the Southern Forest Nursery Association and the Northeastern Forest and Conservation Nursery Association was held at the DoubleTree Hotel and Conference Center in Gainesville, Florida on July 15 to 18. ...

Each spring adult horseshoe crabs migrate from deep bay waters and the Atlantic continental shelf to intertidal sandy beaches to spawn. Horseshoe crabs are an important food source for migrating shorebirds that feed on the eggs, for migrating fish that feed on the eggs and larvae and for Atlantic loggerhead turtles that feed on horseshoe crabs while using the Chesapeake Bay as a summer nursery ...

In fruit and shade tree nurseries, there is a need to count and measure caliper for trees frequently so as to have an accurate inventory sufficiently before harvest since disease, pests and climate can change the yield from year to year. In some tree nurseries it is common practice to count the entire stock three times a year and to caliper them once a year. Both tasks are very labor intensive,...

The aim of this paper is to test inside an input-output model, three precepts of the sustainability strategy of integrated coastal zone management and Post-Normal Sciences: developing decision support tools with holistic perspectives which lend themselves to public participation and handle high uncertainty degrees. Unsustainability is partly due to an inadequate use of “narrow-system-boundary” ...

Abstrac t —Although bocaccio (Sebastes paucispinis) was an economically important rockfish species along the west coast of North America, overfishing has reduced the stock to about 7.4% of its former unfished population. In 2003, using a manned research submersible, we conducted fish surveys around eight oil and gas platforms off southern California as part of an assessment of the potential val...

Pythium species are important soilborne pathogens occurring in the forest nursery industry of the Pacific Northwest. However, little is known about their genetic diversity or population structure and it is suspected that isolates are moved among forest nurseries on seedling stock and shared field equipment. In order to address these concerns, a total of 115 isolates of three Pythium species (P....
