LAKE MANAGEMENT: THE ECOSYSTEM APPROACH

Integrated Ecosystem Assessment: Lake Ontario Water Management

BACKGROUND Ecosystem management requires organizing, synthesizing, and projecting information at a large scale while simultaneously addressing public interests, dynamic ecological properties, and a continuum of physicochemical conditions. We compared the impacts of seven water level management plans for Lake Ontario on a set of environmental attributes of public relevance. METHODOLOGY AND FIN...

Lake Okeechobee Conceptual Ecosystem Model

Lake Okeechobee is a large (1,730 km) freshwater lake located at the center of the interconnected south Florida aquatic ecosystem. The lake is shallow (average depth <3 m), originated about 6,000 years ago during oceanic recession, and under natural conditions probably was a slightly eutrophic and had vast marshes to the west and south. The southern marsh was contiguous with the Florida Evergla...

An Ecosystem Management Approach for the Santa Barbara Channel Islands

Scientists have documented the general decline in the health of marine ecosystems. The human impacts on marine ecosystems are forcing resource agencies and scientists to rethink how society manages ocean and coastal systems. Since the 1960s, the scientific and intellectual basis of an ecosystem-based approach to manage and restore landscapes has been developing with state and federal resource a...

Optimal Management of Ecosystem Services with Pollution Traps: The Lake Model Revisited

In this paper, optimal management of the lake model and commonproperty outcomes are reconsidered when the lake model is extended with a slowly changing variable (describing sedimentation and recycling of phosphorus), which is considered fixed in the simplified version that has been used in the literature up to now. Some intuitive results are reconfirmed but new optimal trajectories are found th...
