Could Digging Ramps Have Unintended Consequences?

This blog post came from Lawrence Davis-Hollander, an ethnobotanist, former director and founder of the Eastern Native Seed Conservancy, author of Tomato: A Fresh from the Vine Cookbook, and  president of botanicalposters.com, the artwork of his wife Margo.

This year, well over 2 million plants of ramps will be harvested for culinary purposes.

My first encounter with ramps took place when I was 19 on a preserve in Connecticut, where I was conducting a vegetation inventory for a summer internship with the Nature Conservancy. For a couple of weeks I tramped along side Dean, a master soil conservationist who reminded me of a younger Euell Gibbons, and his sidekick Ralph, mapping soils. Soil guys always carry a small spade and once Dean spied the ramps he exclaimed “thare’s lunch boys.” For the remainder of the days together when we were in the right habitat, Dean and I would quell the hunger gnawing our stomachs with a snack of raw ramp bulbs. Just brush off the earth and pop them in your mouth.

Since that time I have occasionally dug a few ramps in the spring, savoring their unique subtle flavor when cooked. In recent years I became concerned when I noticed how much media coverage they were getting, how many restaurants were serving them, and food stores selling them. This was no longer the occasional expert forager gathering a few ramps for a meal or two, rather the equivalent of hundreds of people out digging in a patch of ramps. I knew enough about the ecology and botany of the rich woods in which ramps grow to know this was not a good trend.

Commercial foraged samples I saw showed me that they were being harvested carelessly—baby and immature ramps were being dug right along with mature plants. In the Berkshires, where live wild food specialist Russ Cohen lives, I noticed whole patches being decimated.

If you have ever dug ramps you know that sometimes they are quite prolific, yet how long would it take to harm the population?  Unfortunately we have proved that as humans we are quite capable of over utilizing our natural resources for our own designs with too little understanding for the consequences of our actions.  Our best example in the United States is ginseng. Botanists believe ginseng was just as common as ramps are today. Yet ginseng is now virtually extinct from many woods, and generally scarce or rare today.  Ramps, like ginseng, tend to grow in some of our nicest and richest eastern woodlands, those populated by other fragile spring flowers such as Trilliums, Bloodroot, Mayapple, Blue and Black Cohosh and many others.

In talking to many botanists who have looked carefully at ramps and woodland plants there is a concern about the future of ramps due to its new found culinary cache. Harvesting was banned in Smokey Mountain National Park about ten years ago due to field studies showing that the long time traditional local harvesting practices were having a major effect upon ramp populations. As much as 90% of some patches had been harvested, which was estimated to take 100 years to recover. Patches where 25% of the population was harvested were estimated to require 10 years to recover.  Even a harvest of only 5% might take 2 years.

Anecdotal information from old time harvesters indicate that patches have been greatly diminished in the last decade, undoubtedly due to this new interest in wild ramps.

Amongst the concerns voiced by botanists are the reduction of the ability of the plants to reproduce because of over harvesting, disturbance of the woodland habitat by digging and trampling, and the resulting ability of invasive plants to spread.

Studies in Quebec led to a ban on commercial harvesting for the entire province, with only small amounts allowed to be dug for personal use.  Three states now have ramps listed as plants of special concern. While they can be cultivated it takes about 7 years to produce a mature plant. Currently the ramps on the commercial market are all wild dug.

If there is such a thing as a sustainable harvest of ramps, no one currently knows what that number is. Clearly it is under 5%.

An alternative to destroying the whole plant is utilizing the leaves. For flavor the leaves are excellent and keep refrigerated for several weeks.  Leaf harvest is currently being studied. It is not clear how sustainable that practice is. I think it’s possible if not more than 20% of a patch was harvested of leaves each year that this might be sustainable. This is only a guess.
