Park FactsMedano large hill of shifting sand that lacks vegetation
Park contains 10.3 million yd3 of sand
Park covers 414 acres
Dune height varies from 110-140 feet
Important tourist attraction: hosts more than 900,000 tourists each year
Tourist activities: Hang Gliding, Kite Flying, Hiking, etc.
Jockeys Ridge is on the MoveWind has caused the park to migrateDirection of wind shifts throughout year
Summer: wind from the SWWinter and Fall: from the NEPredominant direction of Migration: Park is moving to the SW
Management IssuesDevelopment North of the park has cut off the source of new sand
Migration of the dune field outside the limits of the Park:Entrepreneurs hauling away sand for commercial useEncroachment onto Neighbors property
Human impacts: Recreational activities
Management SolutionsDo Nothing not really a solution
Haul sand away on a regular basis 50,000 yd3 could be moved every five years from the S-end and put on the N-end
Vegetate the Dune:Entire dune fieldSouthern end of the Park
Problems with Management OptionsHauling Sand away is expensive and would have to be done on a regular basis
Vegetating the dune field would stabilize the system but would defeat the purpose of having an active dune
Sand fences and old Christmas trees emplaced along S-end ofpark have been covered with migrating sandWright Brothers Memorial in nearby KillDevil Hills once had a migratingdune.
