17) Disturbance of wildlife

Disturbing, injuring, collecting, or attempting to disturb, injure, or collect any flora, fauna, or other property is prohibited.

a. West Indian manatee Protection Measures

The endangered West Indian manatee (Trichechus manatus) is known to regularly occur in

Lakes Pontchartrain and Maurepas and their associated coastal waters and streams. It also can be found less regularly in other Louisiana coastal areas, most likely while the average

LA – Barataria Basin Landbridge Repair CU 2&7 SP-8 water temperature is warm. Based on data maintained by the Louisiana Natural Heritage

Program (LNHP), over 80 percent of reported manatee sightings (1999-2011) in Louisiana have occurred from the months of June through December. Manatee occurrences in

Louisiana appear to be increasing and they have been regularly reported in the Amite, Blind, Tchefuncte, and Tickfaw Rivers, and in canals within the adjacent coastal marshes of southeastern Louisiana. Manatees may also infrequently be observed in the Mississippi

River and coastal areas of southwestern Louisiana. Cold weather and outbreaks of red tide may adversely affect these animals. However, human activity is the primary cause for declines in species number due to collisions with boats and barges, entrapment in flood control structures, poaching, habitat loss, and pollution.

i. During in-water work in areas that potentially support manatees all personnel associated with the project should be instructed about the potential presence of manatees, manatee speed zones, and the need to avoid collisions with, or injury to, manatees. All personnel should be advised that there are civil and criminal penalties for harming, harassing, or killing manatees which are protected under the Marine

Mammal Protection Act of 1972 and the Endangered Species Act of 1973.

Additionally, personnel should be instructed not to attempt to feed or otherwise interact with the animal, although passively taking pictures or video would be acceptable.

ii. All onsite personnel are responsible for observing water-related activities for the presence of manatees. We recommend the following to minimize potential impacts to manatees in areas of their potential presence:

iii. All work, equipment, and vessel operation should cease if a manatee is spotted within a

50-foot radius (buffer zone) of the active work area. Once the manatee has left the buffer zone on its own accord (manatees must not be herded or harassed into leaving), or after 30 minutes have passed without additional sightings of manatees(s) in the buffer zone, in-water work can resume under careful observation for manatee(s).

iv. If a manatee(s) is sighted in or near the project area, all vessels associated with the project should operate at a “no wake/idle” speed within the construction area and at all times while in waters where the draft of the vessel provides less than a four-foot clearance from the bottom. Vessels should follow routes of deep water whenever possible.

v. If used, siltation or turbidity barriers should be properly secured, made of material in which manatees cannot become entangled, and be monitored to avoid manatee entrapment or impeding their movement.

LA – Barataria Basin Landbridge Repair CU 2&7 SP-9

vi. Temporary signs concerning manatees should be posted prior to and during all in-water project activities and removed upon completion. Each vessel involved in construction activities should display at the vessel control station or in a prominent location, visible to all employees operating the vessel, a temporary sign at least 8 ½” X 11” reading language similar to the following: “CAUTION BOATERS: MANATEE AREA/ IDLE

SPEED IS REQUIRED IN CONSTRUCTION AREA AND WHERE THERE IS LESS

THAN FOUR FEET BOTTOM CLEARANCE WHEN MANATEE IS PRESENT”. A

second temporary sign measuring 8 ½” X 11” should be posted at a location prominently visible to all personnel engaged in water-related activities and should read language similar to the following: “CAUTION: MANATEE AREA/ EQUIPMENT

MUST BE SHUTDOWN IMMEDIATELY IF A MANATEE COMES WITHIN 50

FEET OF OPERATION”.

vii. Collisions with, injury to, or sighting of manatees should be immediately reported to the Service’s Louisiana Ecological Service Office (337.291.3100) and the Louisiana

Department of Wildlife and Fisheries, Natural Heritage Program (225.765.2821).

Please provide the nature of the call (i.e. report of an incident, manatee sighting, etc.);

time of incident/sighting; and the approximate location, including the latitude and longitude coordinates, if possible.
