Fieldmarks for Rainforest Trek Operators

Their trip, your brand

A field guide as deep as the forest.

Your guests didn’t come this far to identify wildlife from a free app they downloaded at the airport — and under the canopy, that app wouldn’t load anyway. Fieldmarks puts the whole forest in their pocket, offline, in your logo and colors, not ours.

Nothing to sign up for. A five-character code from their invitation — or a tap on the link, or a scan of the QR their guide holds up — and they’re in.
Birds, mammals, herps, and more in one field guide — 700+ species for every reserve on the itinerary, with rarity for that region and the filters that matter when the list runs long: group, rarity, seen or not yet.
Everyone arrives with a list; now it’s a shared one. The party’s Most Wanted list turns the group into one search party — live “6 of 9 spotted”, and a moment when the quetzal finally shows.

The day’s story leaves the lodge in your brand.

Today a trek ends with a paper checklist and a camera roll full of leaves. Fieldmarks drafts a branded Field Report from each day’s verified sightings — the guide adds a line and taps approve — and every guest has it that evening: in the app, by email, as a social card one tap from Instagram.

Every share carries your handle — and rarity does the bragging: “resplendent quetzal, guide-verified” is proof no adjective can buy.
The review ask sits inside the story of the trip they just took — Google, Tripadvisor, whichever they use — not in a cold email three weeks later.
The trip closes with the Expedition Chronicle — day-by-day highlights, the trip’s life list, the guide’s closing note — and this year’s quetzal is the reason they book next year’s jaguar. With you, ideally.

See everything

Three lodges, four guides, one screen.

Multi-lodge circuits, freelance guides, activities at every hour — dawn birding, the waterfall hike, the night walk — and the whole picture living in your head and a chat thread. The Trip Board holds it instead: who’s out, what they’ve seen, and what needs attention before a guest feels it — the party nobody has joined yet, the report about to go out, the guide double-booked next Tuesday. And when the question comes months later, the record — which day, which trail, which guide — is verified, time-stamped, and attributed.

Back your guides

A thousand species. One tap to confirm.

The guide hears the antbird before anyone sees it, logs it in a few taps, and keeps walking. Guests log what they think they saw; the guide confirms or corrects it — and the correction is where the learning happens. All of it offline, from the trailhead to the lodge wifi.

Every confirmation carries the guide’s name — photo and bio in the guest app, a note under their own name on any sighting, a Field Report that drafts itself for approval each evening. And Hotspots turn your own sighting history into where the quetzals have actually been this month.

Every trip you sell, the way it actually runs.

Two kinds of trips, one platform: Expeditions, where guests take part, and Tours, where your guide logs the day and every guest receives it — same board, same roster, same login.

Expedition

The birding week

Every guest keeps their own list, the party chases the specials together, and the week ends with a Chronicle in your brand.

The Expedition App →

Expedition

The multi-lodge circuit

One itinerary across three lodges — each stay a segment, regions per day, one code for the whole journey, one Chronicle at the end.

How expeditions run →

Tour

The night walk

A scheduled departure after dark. Your guide logs the frogs and the kinkajou; guests scan a code, leave an email, and the branded Tour Recap arrives — no app, no download.

Questions rainforest operators ask

Does the library go beyond birds and mammals?

Yes — birds, mammals, reptiles, amphibians, fish, insects, and more, with regional lists for your operating areas and rarity calibrated to each. Filters by group, rarity, conservation status, and seen or not yet keep a long list usable.

We move between three lodges on one trip. One trip or three?

One Expedition. Each day carries its own regions, so a lodge change is simply the next day of the itinerary — one code covers the whole journey, and the Chronicle at the end covers all of it.

Do night walks work?

Identically. A departure or an activity after dark logs the same way — the frogs, the kinkajou, the owl — and the recap goes out just the same.

There’s no signal on the trail.

Assumed. The trip downloads before departure; sightings save to the phone with their location the moment they’re logged and sync when the lodge wifi comes back.

Is this more work for our guides?

Less. Confirming a sighting is one tap, bulk actions cover a busy morning, and the evening Field Report drafts itself — the guide adds a line and approves. Freelance guides see only the trips they’re assigned to.

What does it cost for an operation our size?

Plans are sized by trip allowances that scale with your season — never per guide, never per guest. The 14-day pilot is free. See pricing →

The forest keeps its secrets. Your guests keep the story.
