This FEIS species review synthesizes information on the relationship of Polystichum munitum (western sword fern) to fire--how fire affects the species and its habitat, and fire management considerations. Information is also provided on the species' taxonomy, distribution, basic biology, and general management. This species review can be used for fire management, restoration planning, NEPA documents, and postfire rehabilitation planning. It may also be helpful in wildlife and habitat management, and as a source of information on the general ecology of individual species.
