All Aboard! Florida Potential impacts to gopher tortoises
Rachel King, Alex Kalfin
Species Conservation Planning Section
Gopher tortoise
(Gopherus polyphemus)
Only land tortoise east
of Mississippi River
Inhabits sandhill, xeric
hammock, pine flatwoods,
scrub, dry prairie, coastal
dunes, mixed hardwood
pine, pastures, and
disturbed areas
A keystone species
Excavates burrows averaging 15 ft long x 6.5 ft deep
Burrows provide refuge for over 350 other species (commensals)
Loss of the gopher tortoise would result in a dramatic ecological shift
Species status
State listed as threatened
Candidate for listing under
the Endangered Species
Act
September 2012 – FWC approved the revised
management plan
–Conservation goal is to restore and maintain secure,
viable populations throughout Florida so that the
species no longer warrants listing
Conservation objectives
Minimize the loss of tortoises
Increase and improve habitat
Enhance and restore gopher
tortoise populations where they
are depleted
Maintain the gopher tortoise’s
function as a keystone species
Gopher tortoise permitting
Permitting Guidelines approved
April 2008 (revised Feb. 2015)
Includes multiple permit types to
accommodate various projects
–Conservation permit
–Recipient site permit
–Permits for public projects adjacent
to public lands
Conservation permit
Types of projects
–Those with more than 10 burrows
–Phased developments which obtained a 10 or fewer
burrows permit on a previous phase
Relocation of tortoises on-site or off-site to a
permitted recipient site
–Private or public recipient sites
All relocation activities completed
by an authorized agent
Conservation permit mitigation
contributions
Relocated to long-term protected or public
conservation lands recipient sites
–$207 for first 10 burrows (up to 5 tortoises)
–$310 for each additional tortoise
Relocated to short-term protected recipient sites
–$207 for first 10 burrows (up to 5 tortoises)
–$3,098 for each additional tortoise
Relocation to unprotected recipient
sites
–$3,098 for each tortoise
Long-term recipient sites
Perpetual conservation easements
Habitat management plans
Financial assurances
Monitoring
Or Public Conservation Lands
All Aboard! Florida
240 mile high speed train
Existing tracks, however:
–Repair
–Expand
–Curve reduction
–Fiber optic cable
New track to connect to
Orlando International Airport
Potential impacts
Several public conservation
lands with large, stable gopher
tortoise populations
–Tosohatchee Wildlife
Management Area (Orange)
–Savannas Preserve State Park
(St. Lucie)
–Seabranch Preserve State
Park (Martin)
–Jonathan Dickinson State Park

Potential long-term impacts
Impacts of railroads on gopher tortoises not well
known
Note in Herpetological Review in 2007
–Dead tortoise observed between tracks in
Savannas Preserve State Park
–Entrapment, Overheating
Current research looking at barriers for managed
retreat of wildlife as a result of sea
level rise
Project status
Phased project
One permit issued for Orlando International Airport
No gopher tortoise permit or surveys received by
FWC
–Bids for authorized gopher tortoise agents now
–All tortoises are required to be relocated prior to
any site work or soil disturbance related to the
project
