The most healthful vegetables growing in your backyard could be weeds. Lambsquarters and purslane, described by Michael Pollan as “two of the most nutritious plants in the world,” are common wild greens. They thrive in urban environments, popping up in garden plots and sidewalk cracks from Toronto to Texas.

Bamboo is one of the fastest growing plants on earth, and it is notoriously challenging to contain. But if you master some simple harvesting techniques, it could be covering your plate instead of your yard.

Recently the New York Times had a front page article on foraging, or rather, on why the Parks Department may be starting to take a sterner approach towards foragers than it has in recent years. The concern is that rampant foragers will decimate plant populations. I have seen no signs of this. As I am quoted in the article as saying, the majority of the plants I forage in the parks are invasives that are actually crowding out some of the potentially threatened native plants.

“What advice do you have for someone who would like to incorporate more local foods into his or her diet but isn’t sure where to begin?”

That’s a question I’ve been asked frequently, and it deserves more attention than I can usually give it in the context of a quick take-away response.

Maybe you found your way to this website because you have the same question. Or maybe you’re already deeply committed to the local/organic/sustainable food movement, and would like to help others just starting out on that path. Let’s take clear look at how to get started.

Naturalist, author, and environmental educator “Wildman” Steve Brill,America’s go-to guy for foraging, has just released a master series of foraging apps, WildEdibles, that will give iPhone users the in-depth information they need to identify, ecologically harvest, and use 165 of the best wild edible and medicinal plants of North America, plus essential details of 52 look-alikes. The focus will be on eastern species, but half the plants and many more very similar close relatives that are also edible grow across the country.

It’s a reflex by now: I look out the train window and mentally check off the edible and medicinal plants I see. Today there’s burdock, red clover blossoms, dandelions, plantain, wild carrot, nettles. All of those are edible and medicinal as well. Food? Check. Field first aid? Check. There’s a baseline security to being able to identify wild edible and medicinal plants.

“What do you eat in winter?” is a question I frequently get asked when people learn that I eat a mostly local foods diet in the Northeastern U.S.

My reply starts with the fact that I eat just as well in winter as I do in summer. That fact really cheers me up right now. We are at the tail end of winter, but it will still be many weeks until the first spring crops are ready. If I only ate the storage and greenhouse crops available year-round here, well, I’d survive but my meals would be really boring.

Here’s how you can make your “off season” meals as interesting and nutritious for you as the ones you eat during the harvest months, all the while keeping a locavore’s lowered carbon footprint:

Diversification is a fundamental aspect of financial planning, where the old adage, “don’t put all of your eggs in one basket,” often applies. Stocks, bonds and mutual funds are the baskets for your monetary eggs; spread your eggs diligently so that if one basket breaks, you’ve still got others to rely on.

It’s the end of March. Crocuses, magnolias, and the first daffodils are blooming. Looks like spring, but on the local foods front here in the Northeast it would be the bleakest culinary season if I didn’t forage for wild edible plants and mushrooms.
