Visitor displacement is not inherently bad when it is managed. As part of their current management plan, ODNRA/Sand Lake managers use the Recreation Opportunity Spectrum (a zoning tool) to define recreation opportunities for the area, and in a larger regional context, this can be used to minimize Type 1 displacement in some areas (higher levels of regimentation) and Type 2 in others (lower levels of regimentation). To be effective at ODNRA/Sand Lake, clearly stated management objectives are needed for each recreation opportunity zone.
