Ramp season is upon us. Let’s not love them to death.
Nothing breaks the winter doldrums like the pungent taste of these wild onions. Ramp season has arrived sooner than ever this spring and demand for ramps is on the rise. But as gathering and indulging has gone from a local tradition to a regional culinary craze, ramp patches are taking a hit.
Like most of our native flora, ramps (Allium tricoccum) are a long-lived perennial. The leaves are green for only one month of the year, but the bulb lives for many years. A single seed can take over a year to germinate and the plant takes 5-7 years to reach maturity. Every harvested bulb represents several years of growth. A study conducted in Great Smoky Mountains National Park found that a ramp patch takes 10 years to recover from a modest 10% harvest! The same study showed that a patch takes 2.5 years to recover from just a 5% harvest. A sustainable harvest requires digging less than 1 in 10 plants out of only 1 in 10 patches each year. Over the past few years, I have watched entire patches evaporate. This is a recipe for disaster for the species and for those who love to eat it.
For now, there are still sites on public lands where ramps are abundant, but those areas are being dug at an unsustainable rate. If ramps are to be enjoyed by future generations of mountain residents, harvesting and consumption practices will need to change. The only truly sustainable way to harvest and enjoy ramps is to harvest only leaves. Cut one leaf from some of the robust plants that have at least two leaves. Extra caution should be taken to keep your harvest from wilting, but this can be done by keeping the leaves cool, moist, and shaded -- treat it more like fresh spinach or lettuce than like onions. If you are a chef, restaurant owner, or roadside ramp-customer, please buy from reputable harvesters who have harvested in this manner. Pay a premium for these leaves (without the bulb, they will be cleaner and weigh less), but you will know that you are getting the very freshest ingredients for your kitchen.
Not only are ramps aromatic and delicious; they come from some of the most remarkable stands of forest in eastern North America. Ramps grow in Appalachian Rich Cove forests, plant communities that are famous for their diversity of fragile and ephemeral spring wildflowers like trillium and trout lilies. The destructive method of digging with a hand hoe disturbs far more than just the ramps. If you do end up with a mess of ramps that includes bulbs, you can cut off a generous portion of each bulb and replant them, roots intact, in a location where similar rich cove species thrive. In a couple of years, they will reward you with ample green foliage that you can sustainably harvest.
Due to scarcity, Canada was forced to ban ramp harvesting on public lands over 20 years ago. Great Smokies National Park banned harvesting in 2004 and have recently been in discussion with Cherokee leaders over whether to allow the traditional Cherokee method of harvesting leaves while leaving bulbs. Currently the only restrictions on local National Forest land is that commercial harvesting (over 5 lbs) requires a permit and commercial harvests are limited to 500 lbs per permit. Based on the data gathered in the Smokies, these USFS recommendations and policies are due for an update.
One way the USFS keeps tabs on the ramps harvest is by how many commercial permits are issued. The Appalachian Ranger District only issued 26 commercial permits in 2016, with an average reported harvest of 46.5 lbs per permit. However, the system relies heavily on the integrity and honesty of harvesters as well as the outdated harvesting guidelines. If you do purchase ramps, ask whether the seller has a permit. Just as fishing permits help prevent overfishing, collection permits are the only policy currently in place for managing healthy populations of ramps. Commercial harvesters are required to carry their permit on their person and are not allowed to dig next to a trail or within 100 feet of a stream. In order to avoid the “Tragedy of the Commons” that has occurred elsewhere, local harvesting practices need to change before ramps become as rare as ginseng.
