Welcome to the National Wetland Plant List
The National Wetland Plant List is now available for use.
This web site represents a
National effort led by the U.S. Army Corps of Engineers to update the National
Wetland Plant List (NWPL). The NWPL is used extensively in wetland delineation,
wetland restoration and research, and the development of compensatory
mitigation goals, as well as in providing general botanical information about
wetland plants. Updating the NWPL
is a cooperative effort of the Army Corps of Engineers (Corps), the U.S.
Environmental Protection Agency, the U.S. Fish and Wildlife Service, the
Natural Resources Conservation Service, The Biota of North America (BONAP),
states, the academic community, and the scientific portion of the public.
A Note on Web Browser
Security Warnings and Accessing the NWPL
STEP I
The National Wetland Plant List is hosted on a US Army Corps of Engineers web server. Many NWPL users do not regularly access Department of Defense (DoD) web sites. When attempting to access DoD web sites (such as NWPL) that use encryption to protect passwords, you may receive a warning message stating: "There is a problem with this website's security certificate." This is because most web browsers are not set up to trust the identity of DoD web sites by default.
Your browser may let you view the DoD security certificate, accept it, and then proceed to the NWPL home page. If this is the case, follow your browserÕs instructions for viewing, accepting, and saving the DoD security certificate. The procedure is safe even though your browser may make you nervous by providing warning messages that sound unsafe.
If your computer cannot accept the web certificate at this stage, go to Step II.
STEP II
Go to http://dodpki.c3pki.chamb.disa.mil/rootca.html where the DoD security certificate is available for installation.
A DoD security certificate is not necessary to view this website.
STEP III
From the above web site, download only
the Class 3 Root CA Certificate and the Root CA 2 Certificate.
a. Double click on "Download Class 3
Root CA Certificate" then select Open. (If asked, click on Allow to the Crypt Shell Extensions from
Microsoft Windows)
b. Click on the Right facing arrow next to
folder location for the certificate in the left hand pane to expand it, then
double click on "Certificates"
c. On the right hand pane listing the

click the Install Certificate button.
d. Click Next in the Certificate Import
Wizard, select "Place all certificates in the following store" and
click Browse. Select "Trusted Root Certification Authorities", then

Close the certificate manager window and
repeat this process for "Download Root CA 2 certificate". Double click and expand the Certificate
list, scroll to the bottom and double click one of the DoD Root CA 2
certificates. (located at the end of the list) Follow the instructions above to
install.
e. Close your browser. Reopen the browser and
access the NWPL website again.
Based on the feedback we have received so
far, there are two browsers, Mozilla Fire Fox and Safari, that let will you
view the DoD certificate, accept it, and then proceed to the website. Internet
Explorer and Google Chrome require the steps described above.
