The War on Invasive Plants

Invasive Plants: Coming to a Forest Near You

Being able to identify and use plants is a critical skill for living sustainably.

Of course, botany is not the easiest thing to pick up…  So anywhere you get a chance to learn a bit more, you should take advantage of it.  I’m working on a new resource to teach botany to members of the Grow Network right now.  But… in the meantime… you might be able to get some good free information to help you along if you don’t mind getting a little bit creative.

The War on Invasive Plants

Did you know there is a war on invasive plants?

The stated objective of the U.S. Forest Service is to completely eradicate some of the plants that they say are foreign invasives.  Personally, I doubt that eradication will work.  You know, there is a basic universal law that can be summarized as: “What you resist, will persist.”

But you can get a whole new perspective on the situation when you know that many of these invasive plants are actually edible and/or medicinal.

Learning About Your Local Invasives

Invasive species are, by their nature, abundant… and getting more so.  That means these are some of the plants you are most likely to come across if you go out looking.  So, many of them are good candidates for you to learn about.

As I mentioned above, botany isn’t easy.  It’s important that you find good resources to help you along the way.  Personally, I was surprised and pleased to find so much good free information available when I decided to start learning about these plants.

Free information… why not take advantage of it?  And to pay them back for their free information, you can help the Forest Service by reporting invasive species when you find them (if you want to – I’ll leave that decision up to you).

Resources to Help Identify Invasive Plants

The federal government, and the governments of many states, provide a ton of free resources to help you start learning about these plants.

One of the best resources I’ve found is the Forest Service’s invasive species program (http://www.fs.fed.us/invasivespecies/).  I’m not sure if they’re still doing this, but when I contacted them, they agreed to send me a free copy of a DVD-ROM database all about invasive plants across the United States.  They also have several books and pamphlets that they mailed out to me at no cost.

Of course, one of the best resources is going to be a local expert in your region.  Search around and there’s a good chance you’ll find a local workshop that focuses on the invasive plants that are common in your area.

Learning About Useful Invasives

The way I see it – if you can harvest an invasive species and also make use of it – that’s a win-win.  But how can you know which invasive plants are useful?

As you start to identify the invasive plants in your area, search online to find out if each of them is edible, medicinal, or useful in some other way.  You’ll find many good resources, and there is a fair amount of information on this site too (thegrownetwork.com).  When possible, search by both the common name and the latin botanical name for each plant.  Different resources use different names for the same plants.

One of my personal favorite resources is the Plants for a Future database (available for free online at http://www.pfaf.org/).  While the website is free, I definitely encourage you to support PFAF by making a donation or purchasing one of the books or databases in their online shop.

One Example of a Useful Invasive

Here is one example of a plant that is both useful and invasive.  The Forest Service says that autumn olive (Eleagnus umbellate) is an invasive species in much of the northeastern United States.  If you cross-check that plant with the Plants for a Future database, you’ll find that autumn olive is edible… and it’s medicinal.  So, if you live in the northeast – this is one abundant plant that it would be good for you to learn!

Invasive plants are prolific.  If a plant is considered invasive, chances are it is thriving in our climate and spreading rapidly.  So, why not become an ally of them and figure out how we can make use of them?

We are quite lucky to have so many good free online resources to help us as we learn.  Let’s make good use of these resources, and these plants, while they are available.

    another short but sweet article opening up doors or opportunity. I love your prespective of the plants coming in and thriving. They may be here for a reason. Now is a good time to learn about them. I also Love the last comment about using the online resources while we have them. I for one am planning to spend some time “home-schooling” myself and looking for people to learn from. Moving to the Pacific NW I am hoping there will be lots of edibles growing. Thank you very much for your insight and help.

      Hi Angie,

      The Pacific NW has tons of things going on.

    I live in southern Ontario. Am very interested in what edible invasive plants I can harvest. Would the autumn Olive be in my area and what does it look like?

      eat the weeds might be a good resource for you – do a search on it; or try common weeds – in your area
      3 years ago or so i got tired of pulling the same weeds again and again… i looked them up on line and to my surprise, most of them were not only edible but also of medicinal value. Many weeds are up early in the spring and it turns out they contain levels of anti histamine and can help combat some of the spring allergies. My spinach never did well, once it finally came up it got too hot and so my spinach began bolting – i now eat lambsquartes instead, even stores better than spinach! Shepherd’s purse is another prolific weed here, has a wonderful peppery taste, is high in Vitamin C and K as well as sodium and sulfur. It belongs to the mustard family, tastes great in salads or can be used in tea. Dandelion, chickweed, purslane and plantain or other nuisance weeds that are very useful, oh and the ever spreading burdock 🙂 Before you weed, read! that leaves me with only a few to try and get rid off – I started what I call controlled weeds in my garden. They thrive, are free and reseed themselves.

    Just because a plant has some edible or medicinal qualities does not make it a good neighbor. There are reasons why problem invasive plants have been chosen for eradication. Some plants are allelopathic, give off substances which interfere with the growth of other plants. Some plants just out competes other plants or provide so much shade that other plants can not grow near them. The plant you mentioned, autumn olive, is a very nasty species which while having some good qualities also has some very bad ones. Good qualities include pretty berries which are food for birds. Bad qualities, out competes native plants, grows to very large unmanageable size, easily propagated by seeds which are scattered by the aforementioned birds, and is very difficult to eradicate without using an environmentally disastrous herbicide. Please do not spread plants which are considered invasive by the Forest Service or Fish and Wildlife. Our wildlife and pollinators depend on native plants for survival. Let our native “weeds” grow and enjoy them for their food and medicinal qualities but get rid of the invasives when they encroach on your property. Our First Nation people used these native plants for food and medicine for centuries so why don’t we?
