This week's cover dispatch

A wet-season jaguar corridor reopens in the Maya Biosphere — and only our survey teams were on the ground to log it.

Forty-one days of GPS-tagged drone work, six camera-trap stations, and one rarely traversed forest block between Calakmul and the Mirador basin. The first published corridor map from the 2023 survey, with the routing notes our guides kept.

Chapter one · Who actually writes this

PhD ecologists and licensed wilderness guides — not travel influencers with a ring light.

Jungle Life was founded in 2014 by expedition biologist Dr. Mariana Ospina and Captain Rénald Dubois after a 7-year trans-Amazonian field study. Today our editorial board numbers 11 PhD rainforest ecologists and 9 certified wilderness guides, and every byline on this site belongs to a working member of one of those two rosters.

I.

The founding expedition

In 2007, Mariana Ospina and Rénald Dubois launched a 7-year trans-Amazonian field study spanning 4,200+ canopy nights between Manaus and Iquitos. The study produced three IUCN-cited papers on jaguar corridor fragmentation and one of the first peer-reviewed surveys of understory primate density in the Yasuní-ITT grid. Jungle Life began as the internal newsletter their field teams were already circulating.

II.

The editorial board

Twenty names, six continents, one rule: every senior editor must have logged a minimum of 180 canopy nights before their first byline. Our masthead includes PhD holders from the Smithsonian Tropical Research Institute, the Gabon National Park Service research desk at Lopé, and the Danum Valley Conservation Area in Sabah. Captain Dubois still files quarterly from the field.

III.

The publishing record

Since 2014 we have published 1,940+ destination guides and field reports, with an average article length of 3,400 words. Our long-form reporting now draws from 47 active research stations, and our 2023 GPS-tagged drone survey of jaguar corridor fragmentation in the Maya Biosphere Reserve was the first publication to make that dataset public. We were named Sustainable Travel Media of the Year by SATW in 2023.

This week · Six dispatches from active research stations

Read the dispatch

"A glossy travel blog will sell you a canopy. We'd rather hand you a route book, a vetted outfitter, and the wet-season notes from a guide who is still in the forest right now. That is the difference between a trip and a field-tested expedition — and it is the only difference that matters when you are forty kilometers past the last cell tower."

Outfitter vetting · 312 tested, 14% certified

How 312 jungle outfitters in 23 countries become the shortlist that earns our Certified Field-Ready badge.

Since 2016 our editorial board has run every candidate outfitter through a four-axis scorecard. The bar is high on purpose: only 14% clear it. Below is what we test, how the scorecard is scored, and what the badge actually means when you book.

01

Guide credentials

We verify wilderness-guide certification, language coverage, CPR/wilderness-first-aid currency, and prior incident log. A guide without a current WFR cert does not pass, regardless of how good the lodge is.

  • Certification verified per guide, not per company
  • WFR or equivalent within 24 months
  • Bilingual coverage on multi-country routes

02

Safety & logistics

Evac plans, satellite comms, and weather-cutoff protocols are reviewed against the terrain they actually operate in. A river-boat outfitter with no Plan-B for a flood event does not pass.

  • Documented evac plan per itinerary
  • Satellite comms on routes > 4 hrs from clinic
  • Weather-cutoff protocol, signed off

03

Conservation conduct

We require park-fee transparency, no-contact wildlife policy, and a verifiable community-payroll record. IUCN-aligned conduct is the floor, not the ceiling.

  • Park fees itemized on every invoice
  • No-contact wildlife policy, signed
  • Local-guide payroll, audited annually
