Message from the CEO

This year has been one of great accomplishments. I cannot say enough about our amazing staff and partners who come together and give everything they have for the conservation of animals that most others have forgotten. I want to share some of those accomplishments with you as examples of the strength of our partnerships. We have been monitoring Eastern Indigo Snake populations for 5 years in one of their remaining strongholds, the Altamaha River Basin of south Georgia. This year we completed a study using monitoring data on the occurrence of Indigo Snakes basin wide. This study was conducted in partnership with the Georgia Department of Natural Resources and the results will help the state manage snake populations in the future by providing distribution information, an understanding of the factors that influence their distribution, and an understanding of how effective our surveys are at detecting snakes. Our Land Management Team has planted over 312,000 Longleaf Pine seedlings on the Orianne Indigo Snake Preserve and restored thousands of acres of habitat on private and state-owned land with prescribed fire. We have completed construction on outdoor enclosures at our breeding center, The Orianne Center for Indigo Conservation. We have hatched our first Indigo Snake at the center, and have successfully bred and had multiple clutches laid this summer. With the release of snakes this past spring, we have now released approximately 100 Indigo Snakes back into an area where they have been long extinct, restoring a top predator to Conecuh National Forest in Alabama. We successfully translocated 16 tortoises to the Orianne Indigo Snake Preserve, restoring critical habitat for many species of reptiles and amphibians that depend on their burrows. We completed 3 years of telemetry work on Timber Rattlesnakes in Vermont. The data collected during this project will afford us the ability to prioritize land protection and stewardship activities in the region to ensure the persistence of Timber Rattlesnakes in Vermont. There are many more examples of our accomplishments throughout this report and I invite you to continue reading to learn about them from the true experts, our conservation biologists. These are the people conducting the work on the ground to ensure there is a voice and actions taken for the conservation of rare reptiles and amphibians.
Christopher L. Jenkins, PhD CEO, The Orianne Society 3
The Orianne Society is dedicated to the conservation of rare and imperiled reptiles and amphibians. Our conservation efforts are modeled after our flagship program to restore and conserve the Eastern Indigo Snake. We use science to guide all of our on-the-ground conservation actions for these species and the ecosystems they inhabit. We are focused on measurable outcomes and succeed through partnerships, dedication, and hard work.

There is an abundance of conservation groups around the world, all of them doing great things, but no one implements conservation quite like The Orianne Society. First, there are very few groups that are
dedicated to the conservation of rare reptiles and amphibians. This
group of animals is often overlooked in the conservation world and it is difficult to sway public opinion to save these species.

The Orianne Society? What makes Them So Special?
Second, most organizations focus on pieces and parts of conserving a species, for example, protecting land or implementing reintroductions. Here at The Orianne Society, we do our research
and use a comprehensive approach to species conservation. Once we
determine what is causing a species to decline, we develop programs that are aimed at mitigating those factors- not one or two of them, but all of the factors that cause a species to decline.
Third, we carefully select these species. We look to conserve species that act as umbrella species, meaning that by saving these species, we are contributing to conserving the ecosystems they inhabit and many other species that use these environments. And lastly, we monitor our programs carefully to ensure that the model we
are using for species conservation is successful or if changes need to be
made to ensure a species will persist.
That, in a nutshell, is what makes The Orianne Society special.

Lands program Our Lands Program includes both the implementation of land protection and land management and restoration, all to benefit the conservation of rare reptiles and amphibians. We began purchasing tracts of land to be protected as the Orianne Indigo Snake Preserve in 2009. Since this time, the focus of this area has grown to include 48,704 acres. Of this, The Orianne Society owns 2,607 acres and 10,343 acres are owned by cooperating state agencies and private landowners. The remaining area is unprotected. Our ultimate goal is to protect and manage this property through easements, purchase, and partnerships.
Our highly trained Land Management Team works tirelessly to restore and enhance the Longleaf Pine and sand ridges within the Preserve. They know that the protection and management in this area will provide critical habitat for species such as Eastern Indigo Snakes (Drymarchon couperi), Gopher Tortoises (Gopherus polyphemus), and Eastern Diamondback Rattlesnakes (Crotalus adamanteus). The Land Management Team implements practices such as prescribed fire, Longleaf Pine planting, ground cover restoration, invasive species removal, and hardwood timber harvest to meet our goal of restoring this landscape. However, none of this could be accomplished without the cooperation and assistance of our partners. Whether they are private landowners, state or federal agencies, or other nonprofit organizations, our partners are what enable us to be effective on the ground, allowing us to increase the amount of land we can conserve and restore for these unique animals and the ecosystems themselves.

Captive Conservation The Orianne Center for Indigo Conservation (OCIC) is the live animal facility for The Orianne Society’s captive breeding programs and has been in operation since January 2012. The OCIC maintains our current colony of 47 Eastern Indigo Snakes (Drymarchon couperi), our flagship species, for the purpose of propagation and reintroduction. Colony development is driven by the opportunity to acquire genetically relevant founder stock for future reintroduction programs. New techniques to sustain the reproductive potential of the colony continue to be developed in consultation with experts in the field along with original research, and promoting long-term individual health and reproductive viability.
Further scientific studies will be initiated to evaluate and understand environmental and neuroendocrine control of reproduction, along with a better understanding of Indigo social behavior, blood values, hormonal influences, thermal biology and energetics, and nutrition. In addition to our Eastern Indigo Snake Initiative, the OCIC maintains and manages additional captive programs in support of The Orianne Society’s mission. We maintain a large collection of Eastern Diamondback Rattlesnakes (Crotalus adamanteus) and Timber Rattlesnakes (Crotalus horridus) which contribute to our commitment to end traditional rattlesnake roundups in the southeast. In a partnership with the Georgia Department of Natural Resources and the Evans County Wildlife Club, in March 2013 we again participated in the Claxton Rattlesnake and Wildlife Festival by bringing 20 live adult rattlesnakes for exhibit. During the weekend we presented snake conservation talks and hosted an Orianne Society booth to personally interact with festival visitors. Rattlesnake roundups are traditionally kill events (snakes killed for meat and hides) but for the second year in a row, no rattlesnakes were harmed in this unique conversion from “roundup” to “festival”, which proved to be a success on all levels. The OCIC also maintains select startup colonies of endangered snake species as assurance colonies for future work both in captivity and in the field. Current species include Louisiana Pine Snake (Pituophis ruthveni), Mexican Pygmy Rattlesnake (Crotalus ravus), Bushmaster (Lachesis muta) and the Chinese Mangshan Viper (Protobothrops mangshanensis). A selection of local snake species are also part of the OCIC collection for our conservation education outreach programs in the central Florida area.

Conservation Science The Orianne Societyâ€™s Conservation Science Program provides information through researching and monitoring rare and at-risk species. We use this information to guide our on-the-ground conservation efforts, both within The Orianne Society by working with our Land Management and Captive Conservation Programs, and through our network of partners. The Orianne Society is a science-fueled organization and all of our programs use science to inform our on-the-ground conservation actions. Science is our foundation.
EASTERN INDIGO SNAKE The Orianne Society's Indigo Snake Initiative (ISI) works to ensure the range-wide conservation of the organization's flagship species, the Eastern Indigo Snake (Drymarchon couperi). The research and monitoring projects within the ISI address specific questions about Eastern Indigo Snakes in Georgia and Florida that we need to understand in order to protect and maintain existing populations, as well as guide the reintroduction of new populations in places where Eastern Indigo Snakes were extirpated.

Accomplishments in 2012 Conserving EASTERN INDIGO SNAKES • Completed two and one half years of radio tracking 30 Eastern Indigo Snakes in Highlands County, Florida as part of a study examining the effects of landscape composition and configuration on Eastern Indigo Snake population viability in southern Florida. Submitted an annual progress report to the U. S. Fish and Wildlife Service in December 2012. • Began developing an individual-based population viability model for Eastern Indigo Snakes in central Florida that will allow us to determine how landscape composition and configuration influences Eastern Indigo Snake population viability and identify areas where populations can persist long term. • Began collecting DNA from 118 Eastern Indigo Snake tissue samples from 13 counties in central and southern Florida to determine how many distinct populations occur in these regions and how landscape features influence the genetic connectivity of these populations. • Completed a population and landscape genetics analysis on microsatellite DNA data from 285 Eastern Indigo Snakes from 28 different locations across southern Georgia and identified population structure and how landscape characteristics influence that structure. Presented the results of this study at the 2013 U.S. International Association for Landscape Ecology Meeting in Austin, Texas. • Collected microsatellite DNA data from 80 Eastern Indigo Snakes to test for multiple paternities among the juveniles hatched as part of the Eastern Indigo Snake reintroduction program in Alabama. • Completed a fourth winter field season of monitoring Eastern Indigo Snakes through mark-recapture on the Orianne Indigo Snake Preserve and other focal study sites in southern Georgia, capturing and marking 42 individuals, including the first young-of-the-year Eastern Indigo Snake documented on the Orianne Indigo Snake Preserve. • Completed a third winter field season of monitoring Eastern Indigo Snake occupancy in the Lower Altamaha River Drainage, detecting Eastern Indigo Snakes at 10 of our 40 monitoring sites (25%). Prepared an annual progress report for the Georgia Department of Natural Resources. • Used the data from our occupancy monitoring study to identify habitat features at multiple spatial scales that influence Eastern Indigo Snake presence at potential overwintering habitat. • Assisted the U.S. Fish and Wildlife Service in updating and expanding the Recovery Plan for the Eastern Indigo Snake and identifying criteria for recovery and delisting. • Published a manuscript describing the current range-wide distribution and status of the Eastern Indigo Snake in the peer-reviewed scientific journal, Herpetological Conservation and Biology.
Eastern Indigo Snakes are often found in disturbed habitats in Florida but we really are not sure how important these habitats are for Indigo Snakes. A major goal of our research in Florida is to answer the question, “to what extent do disturbed landscapes contribute to Eastern Indigo Snake conservation in Florida?” 11

The Gopher Tortoise Conservation Program (GTCP) works within the Conservation Science's Indigo Snake Initiative to monitor and maintain the health of Gopher Tortoise (Gopherus polyphemus) populations on the Orianne Indigo Snake Preserve. Because Gopher Tortoises are essential to the conservation of Eastern Indigo Snakes in southern Georgia, we want to ensure that Gopher Tortoise populations on the Orianne Indigo Snake Preserve are able to continue to provide quality Eastern Indigo Snake overwintering habitat. We accomplish this by regularly monitoring Gopher Tortoise populations and their response to land management practices on the Preserve.
Accomplishments in 2012 Conserving GOPHER TORTOISES • Finished collecting radio telemetry data on 21 translocated and 15 resident adult Gopher Tortoises on the Orianne Indigo Snake Preserve and Georgia Department of Natural Resources’ Yuchi Wildlife Management Area to determine if those translocated tortoises are establishing residency at their release sites and submitted a final project report in June 2013. • Compared body condition, home range size, habitat use and selection between translocated and resident Gopher Tortoises.

Eastern Diamondback Rattlesnake (Crotalus adamanteus)
EASTERN DIAMONDBACK RATTLESNAKE
The Eastern Diamondback Rattlesnake Conservation Program (EDBCP) works within the Indigo Snake Initiative to promote the conservation of Eastern Diamondback Rattlesnakes (Crotalus adamanteus) across its range. We accomplish this through a combination of field studies that monitor existing populations and scientific research to address specific questions needed to better manage and conserve Eastern Diamondbacks. We then use this information to work with a diverse group of federal, state, non-governmental organizations, and private organizations and individuals to develop management strategies for Eastern Diamondbacks.
Accomplishments in 2012 Conserving EASTERN DIAMONDBACKS
• Completed the second and final field season studying the influence of habitat and landscape characteristics on Eastern Diamondback Rattlesnake occupancy on Georgia’s coastal barrier islands and successfully submitted a M.S. thesis by an Orianne Society graduate student. • Completed a third winter field season of monitoring Eastern Diamondback Rattlesnake occupancy in the Lower Altamaha River Drainage, detecting Eastern Diamondback Rattlesnakes at 16 of our 40 monitoring sites (40%). • Used the data from our occupancy monitoring study to identify habitat features at multiple spatial scales that influence Eastern Diamondback presence at potential overwintering habitat. • Completed a fifth winter field season of monitoring Eastern Diamondback Rattlesnakes through mark-recapture on the Orianne Indigo Snake Preserve, capturing and marking 11 individuals. • Hosted the third meeting for the Eastern Diamondback Rattlesnake Conservation Action Plan at the Orianne Indigo Snake Preserve.

The Orianne Society is working to prevent further declines and promote the recovery of Timber Rattlesnakes (Crotalus horridus) in the Appalachian Region. In Vermont, where there are only two populations remaining, we conducted field studies to determine what habitats rattlesnakes were using at what time of the year. The goal of this work is to provide information to land managers in order to aid them in conserving areas where rattlesnakes occur. We are also working to help update the recovery plan for Timber Rattlesnakes in Vermont. In the southern Appalachians of Georgia and North Carolina, we are monitoring the baseline status of the species to determine the level of decline in this area. This includes both compiling past observations and conducting targeted field surveys.

Accomplishments in 2012 Conserving TIMBER RATTLESNAKES
• • • • •
Tracked 16 rattlesnakes in Vermont in 2012 to determine habitat use and movement patterns Over 2011-2012, marked 144 unique individuals in Vermont. Used movement results to determine which areas to prioritize for future rattlesnake land protection. Continued to support the Vermont rattlesnake removal program. Developed a database of southern Appalachian Timber Rattlesnake habitat areas in north Georgia which combined past observations with surveys in 2012.
Goals for Conserving TIMBER RATTLESNAKES in 2013
• Continue to assist with population monitoring efforts of rattlesnakes in Vermont. • Work to understand and prevent outbreaks of an emerging fungal disease in Vermont rattlesnakes. • Continue surveys for southern Appalachian Timber Rattlesnakes to fill in data gaps. • Initiate a study to understand the effects of fire on Timber Rattlesnakes in Georgia.

HELLBENDERS The goal of this project is to use environmental DNA (eDNA) extracted from river water to detect populations of the threatened Hellbender (Cryptobranchus alleganiensis). Hellbenders often occur at low population sizes and can be difficult to survey. Therefore, a non-invasive method that allows for detection of Hellbenders without extensive survey effort would be a valuable monitoring tool. Monitoring Hellbender populations in an efficient and less time-consuming manner is important as this is a proposed species for listing under the U.S. Fish and Wildlife Service Endangered Species Act.
Accomplishments in 2012 Conserving HELLBENDERS

Goals for Conserving HELLBENDERS in 2013
• Continue eDNA sampling across North Carolina and Tennessee, as well as adding sites in Georgia. • Continue to focus on detecting Hellbenders at sites with either no records or only historic observations to assess current range extent. • Continue to explore eDNA response to Hellbender reproductive activity. • Analyze correlation of eDNA estimates with population size to test potential for eDNA as a population size assessment tool. 16
MIDGET FADED RATTLESNAKE
Midget Faded Rattlesnakes (Crotalus oreganus concolor) are a unique subspecies of Western Rattlesnake that occurs only in Colorado, Utah, and Wyoming. We are using field surveys and habitat modeling to identify areas that are most important to populations and understand the potential impacts of energy development on future persistence. In the past, we have modeled population habitat use that is being used for management in Wyoming and are currently conducting similar work in Colorado.

Midget Faded Rattlesnake (Crotalus oreganus concolor)
Accomplishments in 2012 Conserving MIDGET FADED RATTLESNAKES • Surveyed 95 different potential den sites (based on our Wyoming models projected to Colorado) across western Colorado. • Identified 22 den sites for Midget Faded Rattlesnakes in western Colorado. • Used our survey results to build a preliminary den site model specifically for Colorado. • Met with Bureau of Land Management officials in Colorado to present our preliminary model and provide guidance on how they can be used to guide management of the species on Bureau of Land Management lands.
Goals for Conserving MIDGET FADED RATTLESNAKES in 2013 • Conduct a second year of den surveys to validate our preliminary Colorado den model. • Develop proposals to initiate surveys in Utah to assess status in that state (the core area of Midget Faded Rattlesnake range), as well as to continue monitoring in Wyoming.

Bushmasters (Lachesis spp.) are the largest pitvipers in the world and are iconic species for primary rainforest ecosystems in the Neotropics. Bushmasters are thought to be declining due to habitat destruction and human persecution. Due to the extreme difficulty in locating Bushmasters, they have received very little research or conservation attention. We are initiating efforts to determine the conservation status of the two species of Bushmasters occurring in Central America and use this information for conservation actions.
Accomplishments in 2012 Conserving BUSHMASTERS • Developed partnerships on the Osa Peninsula of Costa Rica (for Black-Headed Bushmasters) and in Panama (for Central American Bushmasters) that will be important for carrying out studies and implementing conservation actions. • Conducted initial surveys in both Panama and Costa Rica to identify field sites, solidify partnerships and help determine techniques that would likely be most successful. • Initiated the Range-wide Bushmaster Partnership to support long-term conservation efforts: initial membership included AZA institutions that are members of the Bushmaster Species Survival Plan and can help provide support for conservation efforts.
Goals for Conserving BUSHMASTERS in 2013 • Develop an effective survey methodology for locating Bushmasters. • Implement regular surveys in Bushmaster habitat to begin to assess current status. • Initiate radio telemetry efforts to provide information on resource use as well as to provide a means to locate additional associated Bushmaster individuals. • Develop an education/outreach module for Bushmasters and other venomous snakes in the area to supplement education efforts already being done by local partners.

Our Western Rattlesnake work includes initiatives to model animal movement connectivity across fragmented landscapes. The result of this work will be an important conservation tool to preserve rattlesnake populations. Most of these types of efforts have focused on large mammals, but reptiles are also susceptible to landscape-level fragmentation. As part of the Washington Wildlife Habitat Connectivity Working Group, we are working to identify key areas for connectivity of Western Rattlesnakes in the Columbia Basin of the northwestern United States. This information can then assist managers in planning future land development.

Model of key habitat areas.
• Collect genetic samples across the modeled habitat areas and corridors. • Use genetic data to test whether predicted connectivity corridors actually increase gene flow. • Focus sampling areas around wind energy installations to better understand the effect of this rapidly growing type of energy development.
Accomplishments in 2012 Identifying PARCAs • Identified 85 PARCAs across Alabama, Florida, Georgia, North Carolina and South Carolina. • Conducted targeted species surveys and a citizen science bioblitz to ground truth herpetofaunal diversity at a subset of PARCAs. • Presented PARCA results at the Southeastern Partners in Amphibian and Reptile Conservation meeting and the US Landscape Ecology meetings.

PARCAs (Priority Amphibian and Reptile Conservation Areas) are areas with either high herpetological diversity or have presence of rare species of conservation concern. These areas are very similar to the more widely known Important Bird Areas (IBAs). This effort involves both computer modeling methods and expert opinion meetings with local scientists and managers to create the final PARCAs for each state. We were involved in the effort to define PARCAs, with the southeastern United States as our focal region. Black-Bellied Salamanders (Desmognathus quadramaculatus)

take action Membership An annual membership to The Orianne Society is more than a tax deduction. It is a chance to be a part of a group effort to conserve the biodiversity of our ecosystems. The membership also makes a wonderful gift. Select our membership plus t-shirt package and not only will the recipient get the usual member benefits, but will also be able to promote snake conservation with our handsome Orianne Society t-shirt. Visit: www.oriannesociety.org/give-gift
Adopt an Indigo Our Adopt an Animal program supports an Eastern Indigo for an entire year and comes with other benefits, such as an adoption certificate and automatic Orianne Society Membership. But the biggest benefit is knowing you raised an Indigo that will be released into the wild so that this species remains the Emperor of the Forest for many generations to come. Visit: www.oriannesociety.org/adopt-indigo
Planned Giving Donâ€™t just plan for your future, plan for the future of reptiles and amphibians and the great places they inhabit. Whether you want to set up an annual donation or plan a deferred gift, we can work together to determine what you want your gift to support and how it will benefit these amazing animals and landscapes.
