Transcript of Indiana Bat

In Indiana, the Indiana bat is a federally listed species Life History Federally endangered species
Population declines and vulnerability to human disturbances in winter have prompted its listing by the USFWS in 1967
A Recovery Plan was developed in 1976 and revised in 1983
A new revision to the Plan is presently underway
Geographic Range - 16 States with majority in Indiana Status Eats aquatic and terrestrial flying insects at night.
Benefits people by consuming many insects that are considered pests.
may eat half their weight a night in insects.
Examples are moths, beetles, midges, flies, wasps, flying ants, weevils, etc. Feeding Shaggy barked or dead trees with exfoliating bark in bottomlands near uplands (e.g., shagbark hickory)
Stream locations serve as flyways as do some forested paths and haul roads
Bridges can be used (especially concrete) for roosting, mating and nurseries
Spring Migration - Late March to May
Fall Migration - August to November Summer Habitat Caves or mines in Indiana
Fidelity for certain caves
Caves need to be constant and cool in room temperature
Well-Ventilated with chimney effect
Spring Staging (Feeding) at Caves
Fall Swarming (Mating) at Caves Winter Habitat Harp Trapping Radio-Telemetry Potential
Hibernacula Surveys North Side (Fencing) Bridge Surveys DNA Analysis Law requires that agencies take into account their actions upon federally endangered and threatened species
Section 7 Consultation is required for any federal agency that permits, licenses, funds, or otherwise authorizes activities; they must also consult with the United States Fish and Wildlife Services (USFWS) to insure that its actions will not jeopardize the continued existence of any listed species. Endangered Species Act (ESA) Biological Assessments require: Biological Assessment USFWS Biological Opinion Species for consideration
Informal consultation & Formal consultation
Biological Assessment incl. Landsape Connectivity & Biological Surveys
Return of a Biological Opinion (BO) by USFWS on jeopardy or not on species and critical habitat INCIDENTAL
BO Studied the Indiana bat under a bridge since 2004 and learned that species:
Indiana bats use bridges in spring and fall during migration as "stop over" areas and for mating
Other species have their young under bridges
Bridge inspections could be combined with check-off list Bridges Commitment in Section 7 Consultation
Provides for Bat Sensitive Information to Contractor
Required before entering work site
Provides for "Action Items" as necessary in Construction
Each video is tailored to the specific section of I-69 Endangered Species Videos
The following hibernacula (caves) for the Indiana Bat were purchased:
Grotto had 16,190 Indiana Bats
Coon had 14,525 Indiana Bats
Clyfty Cave had 828 Indiana Bats
Salamander Cave had 60 Indiana Bats
Total = 31,603 (7.4%) of the total 424,708 population Mist Netting Cumulative Impacts include:
White Nose Syndrome
Wind Farms
Transportation Projects
Cell Towers
Predation Cumulative Impacts Because of White Nose Syndrome, other species of bats may be federally listed
Because of White Nose Syndrome, USFWS has developed a new mist netting protocol that includes screening the project with Anabat first and then from the results, mist netting some sites and not others
Bridges are getting more recognition and regulations
More efforts and more information on Wind Farms
Lastly, more emphasis in Cumulative Impacts Regulatory Trend tcervone@blainc.com

Species Video Communications Currently, we have purchased 27 properties equaling some 8 square miles
Similarly, we have 21 additional properties that are proposed that equal about 3.3 square miles.
If these get added to those committed, we would have 11.3 square miles from 48 different properties.Before the interstate project is completed, it is estimated that we'll have 60-80 properties that equal about 15 square miles.
Mitigation is for forests, wetlands and streams that emphasize "block forest preservation". Summer Habitat Most likely caused by a fungus

New species of cold-loving fungus
Grows only at low temperatures
Slow to attack skin and causes for lesions
If animal survives, lesions heal to scars Indiana Bat White Nose
Syndrome (WNS) White Nose Syndrome WNS started in 2006 in New York State
Since that time, it has spread south, north and then west
In 2011 (January) it was first reported in Indiana
It is estimated that more than 1 million bats have died due to WNS
Winter colony declines in the most affected regions exceed 70% What's happened so far? Learning more about disease and species
Decontamination Protocol to control spread of disease
Closing of many caves to public
Building artificial roosts What's being
done about WNS? Purchased Caves Tier 1 BA (2003)

7 Biological Opinions and 2 Re-Initiations Publications (Geomyces destructans) Economic Importance Food Habits Bats eat half or more of their body weight a night in insects
Many of these insects are agricultural pests (e.g., cucumber beetle) Economic Losses (Boyles et al., 2011 With 1 million bats gone, 660-1320 metric tons of insects no longer are being consumed
Predicted agricultural losses are estimated to be 22.9 billion/year with a min-max of $3.7 to $53 million
Farmers will need to invest about $74/ acre in pesticides to offset bat losses Endangered Species Videos Commitment in Section 7 Consultation
