A model useful for estimating both the numbers of visits per unit time
attracted to recreation sites in a region and the primary social benefits
associated with these sites is developed. The visitor component of the model
predicts use as a function of the characteristics of population centers,
recreation sites and spatial separation. The benefits component of the model
estimates aggregate willingness to pay using an extension of the familiar
Clawson-Knetsch travel cost technique. Novel features of the model include
incorporation of an way to capture substitution effects of price changes and
inclusion of a measure of time cost as well as money cost in the analysis. An
application is provided.

Fishery Declines, and NMFS' National Habitat Conservation

Man's habitat degradation of coastal, estuarine, and riverine systems
most drastically affects estuarine dependent species, and generally at their
most sensitive stages. Habitat loss and degradation, unlike over fishing or
natural mortality, generally leads to permanent population effects. In most
cases, declines in living marine resources are probably due to a combination
of overfishing, habitat degradation and natural factors.

U.S. Marine Fisheries and Restore Coastal Ecosystem Health."

Without including fishery habitat protection as an essential element,
fishery management is merely the management of harvesting, which alone will
not ensure maximum sustainable populations for future generations. In the
view of many, the protection of essential habitats must be adopted as a coequal
objective with protection of stocks if the national goal of conservation
of populations of marine fish and shellfish is to be realized. This paper
provides the rationale for creating a strong National Habitat Protection
Program to rebuild the nation s marine fisheries populations and protect U.S.
coastal ecosystem health.

Resources." Draft Report, National Oceanic and Atmospheric

Coastal marine waters and tributary river systems contain a variety of
habitats such as wetlands, sea grass beds, coral reefs, and mud flats that
collectively are essential to the reproduction, growth, and survival of a
majority of the marine fish and shellfish of the United States. However, such
productive habitats continue to be destroyed and degraded by water development
projects, housing, agriculture, logging, water diversion, pollution and other
human induced ecosystem alterations. Concurrently, marine fishery populations
have experienced great declines due primarily to the combined effects of
overfishing and inshore habitat degradation and loss. Even at todays
depressed population levels, marine fishery resources are extremely valuable -
contributing $50 billion per year to the nation s GNP. A detailed evaluation
of the composition of the U.S. commercial landings of fish and invertebrates
determined that 75% of the total (by weight) and 63% (by value) in 1991 was
composed of species that are dependent for their survival on inshore habitats.
Moreover, between 1978 and 1991, commercial landings of inshore-dependent fish
and shellfish in the lower 48 states declined 18% in weight and 32% in value
