Maintaining Tortuguero National Park Mile Markers
Working along with the Costa Rican Ministry of Environment (MINAE) and the Sea Turtle Conservancy
(STC), Global Vision International (GVI) Jalova is helping to maintain mile markers that are indispensable
for studying the parks nesting sea turtles. These mile markers also assist in GVI Jalovas Jaguar Predation
on Marine Turtle Study.
Running along the beach of Tortuguero National Park are pieces of driftwood standing
tall and painted white with black writing. These pieces of driftwood are positioned every eight
of a mile (approx. 200m) to provide localization for researchers and park officials. Ranging
from mile zero and 2/8 to mile 18, these mile markers are read in order from north to south.
Mile markers are used for studies on marine turtles nesting as well as jaguar predation
upon those turtles by jaguars the STC and GVI Jalova. This is also the most efficient way for the
rangers of TNP to communicate the exact location of poaching activities.
Nightly patrols during turtle season desperately need these mile markers as electronic
equipment such as GPSs have been shown to disturb sea turtles. For this reason sea turtle
researchers use these markers to know their locations on the beach at night. For GVI these
night surveys cover from mile 18 (Jalova river mouth) until mile 14 (Fig 1). During the morning
GVI also uses these markers to monitor the nesting activities of marine turtles. These markers
are used in GVIs Jaguar Predation of Marine Turtles Study to know camera trap locations
within a 1/8 of a mile assisting in the retrieval of cameras and the data analysis of the project.

This February staff and volunteers of GVI Jalova replaced 51 mile markers across three
miles (15-18) of Tortuguero beach. This activity was conducted over two days and 20 different

members of GVI participated in the mile marker maintenance. After a survey that identified
the markers that needed maintenance, nine volunteers and four staff members of GVI Jalova
Conservation Expedition replaced mile markers between miles 18 and 17 with wooden pieces
pre-selected and painted. On the second time, using the whole team, mile markers for the
other two miles were replaced.
Hoping that the mile markers will last many seasons, GVI Jalova is proud of making part
of the history being involved in the conservation of Tortuguero National Park.
