Nearly all of the more than 5,000 respondents to a proposed plan to add a huge swath of wilderness to the national parks system are in favor the idea, federal officials said.

About 100 of the responses were against putting the so-called Rim of the Valley under federal parks protection, many of them representing groups who fear an extensive trails system could interfere with established activities, such as gun ranges, according to Anne Dove, the study’s project manager.

The proposal could end up putting more than 490,000 acres under federal protection from development and keep the areas open for recreational use.
