Re: REGULATED NOXIOUS AQUATIC WEEDS

the same site had this as a Question and Answer:

Q: I�m getting more and more frustrated by uncertain and conflicting information about invasive plants. It seems that governments, both Federal and State, are starting to crack down on individual businesses. However often there is only incomplete inform

You�re right, frequently there is conflicting, incomplete, or out-dated information. Even worse, there is no single source for accurate listings. Since our industry definitely needs this kind of resource, I was motivated to compile something that would be helpful and accurate. It wasn�t long before I realized that creating a master list for publication was definitely a bigger challenge than I had ever imagined. Uncertainties and obstacles arouse almost immediately.

Let�s start with the Federal level. The Federal Noxious Weed List (FNWL) was last updated in September 2000 and can be easily found at www.aphis.usda.gov/ppq/permits/noxiousweed_list.html under the Plant Protection and Quarantine page. This seems simple enough, except that the FNWL found at http://plants.usda.gov/plants/cgi_bin/f ... oxious.cgi is an invalid list last updated in 1999. Go figure � it pays to be careful when checking sources since some sites have invalid or outdated lists.

Most State lists also include the Federally prohibited plants while some States use only the Federal list. Other States have not officially adopted the FNWL but require a permit from the USDA before plants on the list can be moved into their State. Plants listed on the FNWL are not State regulated or enforced unless also included on the State list.

Obtaining complete and accurate State Lists was, on the other hand, a more difficult task for many reasons.

The formal chain of command for State legislation as it applies to noxious weeds is as follows:
1. The State Government determines a plant to be prohibited from sale or have restrictions on import, distribution, or possession (except by permit) within their boundaries, sighting it as a noxious weed.
2. The updated plant list for that state is to be forwarded to the National Plant Board (NPB) for posting on their website www.aphis.usda.gov/npb/statenw.html. (This is the responsibility of the individual States.)
3. The NPB site is supposed to be THE authoritative source for ALL State Nursery Inspectors across the country.

Unfortunately, that�s not always what happens. For example, Alabama has prohibited the sale of Myriophyllum aquaticum in their state since August 2000. Check the NPB site and it is not listed as prohibited even though the NPB updated in December 2000. Alabama�s own web site does not have an available list of noxious weeds. They are not alone; many of the State sites do not post a list.

Remember, ignorance of the law is not a valid excuse. Our State of Maryland Inspector did say he would go to bat for us in the event we did ship Myriophyllum aquaticum to Alabama unknowingly and that we would more than likely win the battle.

But � Washington State added new plants to their prohibited list, effective January 2001, that are still not posted to NPB site. Since they are posted on Washington�s site, we would be liable for shipping prohibited plants to Washington because the information has been made available to the public. (What exactly constitutes �made available�?)

And � Florida publishes a list of Most Wanted �Outlaw� invasive aquatic and wetland plants. The unsuspecting consumer, retailer, or grower (myself included) might be led to believe that they are on Florida�s prohibited list. In fact some are and some aren�t. Florida is not alone; other States publish similar plant pest/weed lists. Pay careful attention to the wording of information when researching.

The most difficult part of this seemingly never ending project was weeding out the inaccurate information. Wyoming shed some light on another reason for confusion. Their own web site (as well as many others) produces different lists from different queries. The reason is some plants have restrictions by county and/or by State. The list will also vary depending on whether the restriction is a ruling, statute, or law, and which branch of government it falls under. Additionally it may depend upon whether the noxious weed restriction is for the plant or the seed.

Even more problems are created because noxious weed lists are not always maintained by the States� Department of Agriculture. Sometimes they fall under the Department of Wildlife and Fisheries, the Department of the Environment, the Department of Natural Resources, or another branch of government.

More conflicts arose from �comprehensive� sites that seemed to have everything in one place. The noxious weed list on Maryland�s web site is a link to the INVADERS Database System posted by the Agricultural Research System and the USDA. I was sure I had a great find since I could search every State from a single site. So I printed a few for comparison and found that most of the lists did not match or even come close to the list faxed to me by that State. (Could that be because the ruling, statute, law, seed, or plant �thing� generated mixed information for the queries?)

To get around all these ambiguous situations I faxed a request to the States without current information available on their web site. My request to them was to provide a confirmed list of aquatic plants they regulate as noxious weeds. The replies I received provided the core of my �Regulated Noxious Aquatic Weeds� list. When clarification was needed, I chose the faxed information as the official version.

A complete accounting of the researched information has been compiled into two lists. The first is the �State & Federal Contacts for Invasive Aquatic Plant Information.� The second is a list of �Regulated Noxious Aquatic Weeds� and their restrictions by State. I cannot assure absolute accuracy, but I am confident this is a far better accounting than previously available. Both lists can be found in PONDKEEPER Magazine�s Annual Buyers� Guide and PONDKEEPER has generously offered to post a perpetual work in progress list on their website, www.pondkeeper.com.

This raises some interesting questions to the industry as a whole:

How often is the USDA and National Plant Board site updated?

If the industry makes every effort to regulate itself, how much effort will be placed on each company that ships interstate? Will each have to come up with a complete and accurate accounting of prohibited or restricted plants to individual states if the formal chain of command is not followed in a timely manner?

Can we rely on industry volunteerism to be the source of current information for new plant restrictions in various states?

Could a corner of Pondkeeper magazine be dedicated to announcing new additions to the list/s?
Editor�s note: Yes, consider it done. As information is faxed or emailed to us, it will be published.

Should the same information be published in other trade magazines and/or journals?

Would the publicity of prohibited and restricted plants have an impact on their sales in states where they are not prohibited? How could it effect the industry�s reputation?

How involved in the process does the industry want to become?

Now I seem to have raised more questions than I answered. Any feedback out there????
