                 Protecting  Endangered
                 Species
                 Interim  Measures
                 Clark County, Nevada
                     The information in this pamphlet is similar to
                     what the U.S. Environmental Protection
                     Agency (EPA) expects to distribute once our
                Endangered Species Protection Program is in
                effect The limitations on pesticide use are not
                law at this time, but are being provided now for
                your use in voluntarily protecting endangered and
                threatened species from harm due to pesticide
                use. We encourage you to use this information.
                We also welcome your comments.

                  The Endangered Species Act is intended to
                protect and promote recovery of animals and
                plants that are in danger of becoming extinct due
                to the activities of people. Under the Act, EPA
                must ensure that use of pesticides it registers will
                not result in harm to the species listed as
                endangered or threatened by the U.S. fish and
                Wildlife Service, or to habitat critical to those
                species' survival. To accomplish this, the EPA
                expects to implement program requirements •
                beginning in 1994. This program will protect
                endangered and threatened species from harm due
                to pesticide use.
                  EPA requests your comments regarding the
                information presented in this publication. Please
                let us know whether the information is clear and
                correct Also tell us to what extent following the
                recommended measures would affect you typical
                pesticide use or productivity. This information
                will be considered by EPA during the final stages
                of program development

                                                       This publication contains a County Map
                                                      showing tlie Area within the county where,
                                                      pesticide use should be limited to protect listed
                                                      species. These areas are identified on the map by
                                                      a shaded pattern. Each shaded pattern
                                                      correspondls to a species in need of protection.
                                                       The Shading Key shows the name of the species
                                                      that each shaded pattern represents and often
                                                      describes the shaded area. The area may be

                                                      Active Ingredients" lists the active ingredients for

                                                      Codes listed underneath them.
                                                       The Code indicates the specific limitation that
                                                      is necessary to protect the species. The section
                                                      titled Limitations on Pesticide Use explains the

How To Use This Information
1) On the county map, find the specific shading patterns that cover, or are close to, the area where you will apply
   pesticides.
2) Read the descriptor in the Shading Key for those patterns; this may further identify the area involved.
3) In the "Table of Pesticide Active Ingredients," locate the active ingredients in the pesticide you intend to apply.
4) Locate the code to fhe right of the active ingredient name and under the shading patterns that apply to you.
5) When using the pesticide, you should follow the limitations indicated for those  codes described under "Limitations
   on Pesticide Use."
6) If you are applying more than one listed active ingredient or applying a listed active ingredient in an area with
   more than one shaded pattern (species), multiple codes may apply.  If so, you should follow the most restrictive
   limitation.
7) Read the information on Reducing Runoff and Drift on the back of this pamphlet.

                                    Reducing Runoff and Drift
Careful use of pesticides can diminish harm to the environment and reduce exposure of endangered and threatened species
to pesticides. Using pesticide runoff and drift measures may be helpful in keeping more of the applied pesticide on the
field and may also lower your costs of pesticides.

Runoff
Where possible, use methods which reduce soil erosion, such as limited till and contour plowing; these methods also
reduce pesticide runoff .
Where feasible, use application techniques such as T banding and in-furrow techniques, which incorporate the pesticide
into the soil.
Pesticides with ground water warning labels are more likely to enter ground and surface water than those without such
warnings. When possible, use a pesticide that does not contain a ground water warning label.
Keep Informed about changing weather conditions, and try to avoid pesticide application when heavy rainfall is expected.

Drift
Wind direction, speed, and evaporation are important factors in reducing drift. Most importantly, pesticides should be
applied when the wind direction is away from areas of concern; try to avoid application during periods of high winds.
Avoiding applications during the hottest part of the day, when evaporation is highest, will further reduce drift.
When high winds and excessive evaporation are not present, a drift retardant may be useful for aerial applications.

Using the largest droplet size compatible with the pesticide coverage will reduce drift. Typically, higher spray volumes
will also result in less drift.
