Pest Management<br />
Herbicide treatment does not occur in proximity to potential western snowy plover foraging<br />
habitat <strong>and</strong> mosquito control does not occur during the time that plovers would be likely to occur<br />
on the Refuge, therefore, no adverse effects to plovers would result from the implementation of<br />
pest management on the Refuge under this alternative.<br />
Public Use<br />
The potential effects to the western snowy plover of continuing to implement the existing public<br />
use program on the Refuge would be the same as those described for waterbirds in Section 5.4.1.1.<br />
5.5.1.4 Effects to Salt Marsh Bird’s-Beak<br />
<strong>Wildlife</strong> <strong>and</strong> Habitat Management<br />
Salt marsh bird’s-beak is not currently known to occur on the Refuge; however, there are historic<br />
accounts of its presence around Anaheim Bay. Several unsuccessful attempts have been made in<br />
the past to establish a population of this species on the Refuge. Alternative A would not renew<br />
these attempts; therefore, this alternative would neither benefit nor impact this listed species.<br />
Pest Management<br />
Salt marsh bird’s-beak is not currently known to occur on the Refuge <strong>and</strong> Alternative A would not<br />
renew attempts to establish this species on the Refuge; therefore, no effects to this species would<br />
result from ongoing pest management.<br />
Public Use<br />
Salt marsh bird’s-beak is not currently known to occur on the Refuge; therefore, no adverse or<br />
beneficial effects to salt marsh bird’s-beak would result from the public use program carried out<br />
under Alternative A.<br />
5.5.1.5 Effects to Eastern Pacific Green Turtle<br />
<strong>Wildlife</strong> <strong>and</strong> Habitat Management<br />
Eastern Pacific green turtles have been observed in the 7 th Street Pond as well as the channel<br />
leading to the 7 th Street Pond, therefore, any enhancement work or culvert replacement projects<br />
proposed in this area, as well as throughout the Refuge, could adversely affect this species if<br />
appropriate measures are not implemented to ensure their safety. Measures that would protect<br />
turtles present on the Refuge would include: conducting a presence/absence survey for turtles<br />
prior to <strong>and</strong> during any proposed construction, using impingement barrier structures, rock filters,<br />
or other types of exclusion structures around temporary water intake structures to prevent turtle<br />
entrainment, prohibiting the placement of any materials into subtidal habitat that have the<br />
potential for entangling sea turtles, <strong>and</strong> considering potential turtle movement in the design <strong>and</strong><br />
sizing of culverts <strong>and</strong> water control structures. The incorporation of these measures into future<br />
construction project specifications would avoid any adverse effects to sea turtles.<br />
Pest Management<br />
Activities associated with invasive plant control <strong>and</strong> mosquito management would not be expected<br />
to adversely affect the sea turtles that are occasionally present on the Refuge, provided all<br />
pesticides are applied in accordance with label requirements.<br />
Public Use<br />
The public uses permitted on the Refuge under Alternative A are restricted to the roads <strong>and</strong><br />
pathway that traverse the upl<strong>and</strong> areas surrounding the Refuge’s sensitive wetl<strong>and</strong> areas. The<br />
open water areas of the Refuge where sea turtles have been observed are closed to any public use,<br />
