Spring is here! Although it might have arrived a bit early and caught some of

us off guard. There has been a tremendous amount of activity in the tortoise

world since our last newsletter. In November 2017, a number of us met at

the Jones Ecological Research Center in Georgia to participate in a workshop

organized by the Gopher Tortoise Council and funded by the U. S. Fish and

Wildlife Service through a grant to the Jones Center. We met to identify the

number and distribution of viable tortoise populations necessary for the

stability of the species throughout its range. This was after a series of pre-

meeting webinars, homework, and mapping exercises intended to focus our

discussions. Representatives from the Gopher Tortoise Council, the gopher

tortoise conservation community, scientific community, and state and federal

agencies within the tortoise range came together to describe “conservation

units” in each state based on Environmental Protection Agency Level IV

Ecoregions such that conservation units would match, where possible, as they

crossed state lines. We were also able to utilize a modeling tool developed by

Clint Moore (University of Georgia/U. S. Geological Survey) to estimate

persistence probabilities based on different numbers of populations and

population sizes in each state. This workshop was extremely informative and

highlighted the continued efforts needed to understand this species and what

is required to ensure its persistence into the future.

For our Florida members, the Gopher Tortoise Council has recently expressed

its support for the creation of a specialty gopher tortoise license plate whose

sales would benefit the tortoise through habitat protection, education,

research, and increased public awareness. Chelsey Vowles initiated the

concept of the creation of a specialty plate to benefit tortoise conservation

and brought it to the attention of GTC. Though this effort has many hurdles to

overcome, we hope that it will be successful and become a means to provide

additional resources to conserve the tortoise and its habitat in Florida.

As temperatures warm and we emerge from our “burrows”, please remember

to mark your calendars for the 40th Annual Gopher Tortoise Council Meeting

to be held at Archbold Biological Station (www.archbold-station.org) on

October 12-14, 2018. Except for the Saturday night social and awards

dinner, all activities will take place at the station, utilizing the Frances

A Gopher Dawn—More on Gopher Tortoise Fossil History

MORNING COMES EARLY FOR THE FOSSIL HUNTERS. Florida Museum of Natural History paleontologists step from

the bunk house at the Sand Creek Ranch, near the town of Crawford, Sioux County, Nebraska. It’s very early with

the morning sun barely reaching the tops of the distant pine ridges. After cups of coffee and toast we stiffly

manage to climb into the field vehicles for another trek into the surrounding badlands. An early departure is

essential to escape the sweltering mid-afternoon heat when temperatures can reach 116 degrees. The morning

exploration will last about 5 hours before it gets just too hot to work! By noon, the team retreats back to the bunk

house for lunch and shelter. The team will venture out once again after 5 PM, as the shadows and coolness creep

back into the deep ravines. We will work until about 10 PM, when dusk descends on the landscape.

The team will hunt fossil vertebrates in the ranch's eroded badlands, formed from river sediments and thin layers

of volcanic ash, deposited 29 to 35 million years ago by a proto-White Water River. I am specifically looking for

fossil tortoises that had met their fates during the late Eocene and Oligocene epochs.

The badlands on the ranch have been given colorful identifying names such as Horse Hill, Twin Buttes, The 560,

and Bald Knob to name a few. Today the team will explore the Turkey Foot Badlands on the far eastern side of this

remote 11,000-acre ranch (Figure 1). Each of us will spend hours just walking the narrow ravines, climbing steep

eroded walls, and treading precariously along knife-edge ridges in search of exposed bones. Rock-hard, these

bones gleam white or greenish in the available light, standing out against their more subtle grayish background.

Gathering our packs with rock hammers, screw drivers, notebooks, GPS devices, plaster bandages, and lots of

water, we disembark from the trucks and scatter into the eroded maze of ravines. Once a bone is discovered, the

collector makes an initial identification, marks the spot using GPS, notes its position with regard to local ash

layers and other geologic features, and then carefully begins the excavation of the fragment to determine whether

this piece is just that or whether there is a more complete specimen buried behind it (Figure 2). If a significant

find is discovered the collector will unearth the fossil from its sediment tomb, covering the fragile bones in tissue

paper and surrounding the fossil-bearing sediment chunk with wetted plaster bandages-much like a doctor caring

for a broken arm or leg (Figure 3). After the plaster dries, the cap-like jacket is broken free from its attached

pedestal, flipped over, labeled, and carried back to the truck for transport. THESE JACKETS CAN WEIGH

HUNDREDS OF LBS!

A SEQUENCE OF WHITE RIVER TORTOISES. The White River sediments span more than 6 million years of time. Its

chronology is conveniently marked by volcanic ash layers that have been precisely dated by argon isotope analysis.

Each ash layer is featured by its purplish-white signature. The most prominent is referred to as the PWL, a thick

ash band in the mid-Orellan member of the Brule formation. Hence, we can accurately age the fossils by their

position to these bands.

I have classified the fossil tortoise complement from the White River sediments into as many as eight

morphotypes, three of which were described and named by earlier paleontologists. The remainder of this

chronofauna is still in need of definition. These distinctive tortoise types occur as species pairs, each associated

with different rock formations and times within the White River sequences. The tortoise fossils bridge the late

Eocene, Oligocene, and the basal Miocene, spanning the classical Chadronian, Orellan, Whitneyan, and Arikarenan

land mammal ages.

A Chadronian species from the Peanut Peak Formation at the ranch appears to be Stylemys amphithorax, a

species described by Edward Drinker Cope from Colorado in 1873. The Orellan pair includes the earliest known

fossil gopher tortoise and Stylemys nebrascensis. The gopher was originally named Gopherus laticuneus by Cope.

This species was later renamed Oligopherus laticuneus by Howard Hutchinson in 1996, in recognition of its

primitive morphology. The companion Stylemys nebrascensis was described by Joseph Leidy from the Nebraska

Territory in 1851. Both Orellan species are also known from Colorado, Montana, North Dakota, South Dakota, and

Wyoming.

A SPECULATION. Imagine a scene 31.2 million years ago-Morning light streams across the grasslands in what

today would be northwestern Nebraska. Two tortoise species live along the proto-White River that flows through

this vast Nebraska plain. A large gopher tortoise lumbers from its night-time warren, excavated into the side of a

steep-sided arroyo. While warming himself in the new sunlight, he watches the herd of ponderous rhino-like

brontotheres browse among tree leaves along the margins of the braided river below him. His species type

excavates shallow lodgings into the walls of the wash, more like shallow caves than the typical tunnels dug by

more modern gopher species. These subterranean shelters provide some measure of protection from would-be

predators, tramping herds of grazing rhinos, horses, and camels, and extremes in seasonal weather conditions.

The tortoise no doubt watches and listens from his lonely sentinel mound for giant pigs, bear-sized dogs, and other

potential predators before venturing beyond his protective surroundings. He and his kind probably inhabit the drier

upper slopes of the valley and feed on coarse grasses, herbs and shrubs that grow in this broken country. The

second tortoise species, only vaguely related to the gopher, but with higher domed shells, favors the lower, moister

riparian strips near the river, where it feeds on higher quality food plants, finds shelter among tree-falls and

floodplain debris, and soaks in residual floodplain pools…

Richard (Dick) Franz is Emeritus Associate Scientist at the Florida Museum of Natural History and has contributed

previous articles on the fossil history of gopher tortoises.

FEATURE ARTICLE by Elizabeth Parsons, Sarah I. Duncan, and JT Pynne

Examining Factors that Affect the Current Distribution of the Southeastern Pocket Gopher

Introduction

Southeastern pocket gophers (Geomys pinetis) are not typically the gophers discussed in this newsletter! However,

the medium-sized, fossorial rodents do share some commonalities with gopher tortoises as both species are

associated with the deep, sandy, well-drained soils of the Coastal Plain in the southeastern United States.

Historically, pocket gophers have inhabited longleaf pine savannas throughout Alabama, Georgia, and Florida

(Figure 1). Today only about 3% of the longleaf system remains intact and much of what is left is heavily

fragmented (Landers 1995, Van Lear et al. 2005). Similar to gopher tortoises, pocket gophers are important for

the region due to the valuable ecosystem services they provide such as nutrient cycling and soil aeration through

their extensive tunneling activities. Pocket gophers are generally categorized as allogenic ecosystem engineers

because of these activities that dramatically alter the landscape. Research has shown that pocket gophers create

physical structures in the form of mounds and tunnel systems that promote plant diversity and resilience in the

ecosystems in which they live (Jones et al. 1994, Reichman and Seabloom 2002). Pocket gopher tunnels also

provide shelter and foraging for many other species including the gopher frog (Lithobates capito; Blihovde 2006) and federally listed eastern indigo snake (Drymarchon couperi; Miller et al. 2012). Additionally, several species of arthropods are found only in the tunnels of southeastern pocket gophers (Cartwright 1939, Skelley and Gordon

2001). Unfortunately, another similarity the two species share is population declines across their native range.

Additionally, pocket gopher distribution is potentially even more limited than the gopher tortoise due to stricter

habitat requirements such as soil texture, drainage, and openness of habitat. Pocket gophers are considered

species of conservation concern in all three states and are currently listed as a threatened species in Georgia.

Given the important ecological role and the potential population decline of the species, it is imperative that we

learn more about the ecology, natural history, distribution, and population dynamics of the southeastern pocket

gopher in order to develop tools to properly assess and monitor southeastern pocket gopher populations. In order to address the lack of data for this species, investigators from Auburn University, University of Florida, University of

Georgia, and the Joseph W. Jones Ecological Research Center are working to gather information on the distribution

and abundance of the species, and identify the key habitats essential to the conservation of the species.

Methods

Using habitat data collected on the ground and data from remote sensing and publicly available datasets, our goal

is to identify habitat factors and landscape features that influence and limit the southeastern pocket gopher’s

distribution. To update the current distribution of the species and examine factors that promote pocket gopher

presence, we conducted line transect distance sampling surveys on public and private lands across the pocket

gopher’s range. We defined the extent of the natural pineland system within the range of the southeastern pocket

gopher (IUCN 2008). We overlaid a 1 X 1 km grid over the areas and randomly selected patches to survey using a

pseudo-stratified random sampling design based on the National Land Cover Data Set (NLCD; Homer et al. 2011)

in order to include potential pocket gopher habitat that was represented on both public and private lands. The

surveys, modified from gopher tortoise distance sampling protocol (Stober and Smith 2010), were conducted in

the growing seasons of 2016 and 2017. Each survey patch was surveyed independently by two researchers. The

number of mounds were counted and georeferenced in order to determine the cluster distance from the nearest

transect line. Vegetation characteristics such as hardwood and pine basal area, canopy closure, vertical ground

cover such as height of shrubs and grasses, and percent ground cover (woody, forb, grasses, bare/sand, litter)

around the mounds were recorded at up to 10 mound clusters within a survey patch and along the survey line

every 200 meters regardless of gopher presence.

Page 8 The Tortoise Burrow

Results

We performed a total of 187 surveys during the growing seasons of 2016 and 2017 (Figure 2). Preliminary

results from the distance sampling show that the naïve occupancy, or the proportion of sites where the species

was detected at least once without accounting for any variable influences such as vegetation or soil attributes,

was 0.04, 0.25, and 0.40 for Alabama, Georgia, and Florida, respectively. Additional analyses are being

performed to identify factors that promote pocket gopher presence. General trends show that areas of open

grasslands and open pinelands are more likely to have gophers present. However, there are several areas that

seem to be pristine gopher habitat that have no animals present. Anecdotally, we have noticed several species of

herpetofauna including eastern spadefoot toads and eastern hognose snakes utilizing different aspects of the

pocket gopher mounds and tunnel systems.

Current Distribution of the Southeastern Pocket Gopher...continued

Ongoing Research

Using pocket gopher presence data from our surveys, we identified locations to trap live pocket gophers to obtain

tissue biopsies for genetic analyses. Basic morphometric data were also recorded including weight, body length,

and sex. This data will be used to assess the genetic health, population connectivity, and the current phylogenetic

status of the southeastern pocket gopher.

An additional goal of this research is to develop techniques for translocating individual pocket gophers. This

aspect is ongoing, but will provide information on efficiency of establishing viable populations to suitable areas

where pocket gopher populations have declined.

Conclusions

Our preliminary results show that southeastern pocket gophers are now likely extirpated from much of their

historic range. While the reasons for decline are not well known, the loss and fragmentation of longleaf pine

forest, changes in land use, and overall loss of suitable habitat are potential contributors. While the loss of

longleaf pine forests has been substantial, there have been recent efforts in restoring these habitats. Due to their

importance in ecosystem function, the restoration of pocket gopher populations should be considered in holistic

efforts to aid restoration of longleaf communities.

Kids’ Corner

This edition of the newsletter has a feature article on the southeastern pocket gopher! See pages 7-9.

Check out this section for some fun facts and a few questions to test your knowledge (Answers at the bottom of page 12!)

Now you see me!

Now you don’t!

Did you know ? The pocket gopher’s scientific

name is “Geomys pinetis”? The first part

of the genus name (Geomys) comes from

the Greek word Geo meaning “earth” and

the second part of the genus name is mys

meaning “mouse” (so “Earth Mouse”!).

The species name, pinetis, is Latin

meaning “a pine wood” or “of the pines”.

So our little “earth mouse” likes to live in

open pine woods with sandy soils and lots

of grass and broadleaf herbs to eat.

Question 1. Do you know how the pocket

gopher got its common name? Check out

the photos on page 9 for a clue!

Question 2. Name the three states where

southeastern pocket gophers live (clue on page

8!)

Pocket gophers spend most of their time in underground tunnels and are seldom seen...a patient land manager captured the images on this page and the next over a period of about 5 minutes!

I’m back! Question 3. Pocket gophers dig

underground tunnels and push up

mounds of soil. What part or

parts of their body do they use to

dig their tunnels?

Did you know that in a study done in

Ocala National Forest pocket gophers

pushed up sandy mounds weighing up

to 3.6 tons of soil per acre per year on

average! Super Gopher! Must be why

some folks call them “Sandy Mounders”!

Question 4. In the picture

to the right a biologist has

marked the location of

pocket gopher mounds

with yellow flags. It’s

likely that all of these

mounds were created by

one animal because

pocket gophers generally

live by themselves (except

for when mama gophers

are taking care of young).

Can you count how many

mounds (yellow flags) are

inside the black circle?

1. Pocket gophers have external fur-lined cheek pouches-like pockets– to carry vegetation underground.

2. States that contain the range of the southeastern pocket gopher (where it lives) are Alabama, Georgia and Florida

3. Pocket gophers use their long front claws to dig through soil. They use their large front teeth (incisors) to chew through roots and

vegetation but sometimes to help dig through soil. They use their back feet to shove dirt out behind them!

4. Seven mounds are flagged inside the black circle
