Chapter 15: The sloth and the otter
CAMILA
On Wednesday she got lost in the flooded forest and found a giant river otter.
She hadn’t been supposed to go into the flooded section — her survey transect for the day was along the elevated eastern ridge, which stayed above the flood line, and she’d started out correctly. She’d been moving along the ridge for an hour when she’d seen the sloth.
It was in the canopy to the left of the trail, which meant it was in the beginning of the flooded section, which meant she had to stop and watch it from the ridge edge rather than moving below it for a better observation angle. She watched it for ten minutes from the ridge, logged it in her catalog, photographed it in the insufficient light through the canopy.
Then the sloth moved — the slow, deliberate, unhurried movement of an animal that had nowhere to be and all the time there was — and she followed it.
Following the sloth meant leaving the ridge. She did it carefully — she had her GPS, she had the trail back clearly marked on her unit, the flooded section here was shin-deep according to yesterday’s survey data and she had good boots. She went in.
The sloth went up. She photographed it from a better angle. She was noting the individual’s characteristics for the catalog when she heard the otter.
Giant river otters had a call like nothing else in the Amazon. She’d heard recordings. She’d never heard one in the field. The sound was—it was large, was the only word she had for it initially. Large and communicative and coming from the flooded channel to her left where the forest understory disappeared into brown water.
She went toward the sound.
She found the family fifteen minutes into the flooded section: two adults and three juveniles on a partially submerged log, the adults doing the calling while the juveniles investigated the water around the log with the specific chaotic energy of young animals. The family was unconcerned with her presence. She froze at ten meters and watched.
Giant river otters were endangered across the Amazon. She’d never seen one in the field. She’d published a commentary on the species’ population collapse in the western basin the previous year. She was standing ten meters from a family of five in a territory where their presence had been protected for two centuries.
She spent an hour with the family.
She photographed them, measured the adults from distance, documented their behavior, noted the specific section of the flooded forest they were using. She was thorough and she was also aware that she was watching something she’d spent years wanting to see and that the awareness was affecting her more than she was going to write in the field notes.
She wrote it in the personal section of her notebook instead.
She wrote: *they were entirely at ease. The juveniles came within four meters to investigate me. The female adult — the larger of the two — watched me with the same quality that everything in this territory watches me: not suspicious, genuinely curious. This territory’s animals have been in contact with people their whole lives and the contact has been — good. They have no learned fear. That takes generations to produce.*
She wrote: *the territory is full of things that would be remarkable anywhere else and here they’re just here.*
She found her way back to the ridge, back to the trail, back to the station by mid-afternoon, muddy to the hip and carrying three pages of otter documentation and the sloth data and a further conviction that had been building for two weeks that this territory was something that needed to be seen by every conservation biologist in the western basin.
Dante was in the lab when she came in.
She said: *I found river otters.*
He looked up from the data terminal.
She said: *family of five. Adults and three juveniles.* She put the field bag down. *Giant river otters. In the flooded section east of the ridge trail.*
He said: *that’s the family that has been using the eastern channel for six years.* He said it with the quality of someone who had been watching these animals for a long time. *The juveniles are from this year’s season.*
She said: *you know them.*
He said: *I know the family. The adults were born in the territory. Their parents were born in the territory.*
She said: *endemic population.*
He said: *for three generations of otters, yes.* He paused. *The territory is large enough to support a small breeding population without outside input. The river connectivity maintains genetic exchange at a sustainable rate.*
She sat down at the lab table and looked at him.
She said: *this territory is — I’ve been in the field for seven years. I’ve done six major surveys in the Amazon basin. I’ve worked in three other regions.* She paused. *This is the most ecologically significant site I’ve ever been in.*
He said: *yes.*
She said: *the jaguar population anomaly is the least of it.*
He said: *the jaguar anomaly was the most visible hook in the regional data. The full picture is more than the jaguar population.*
She said: *the full picture is a two-century conservation program that has produced outcomes that no institutional program has come close to.* She looked at the data terminal. *The river otters. The endemic orchids. The old-growth canopy structure. The prey species balance. A community maintaining a multi-species ecosystem across six adjacent territories for two hundred years.*
He said: *yes.*
She said: *the contingency record is going to be significant.*
He said: *yes.*
She said: *it’s going to be — Dante, this is the most important documentation project I’ve ever been asked to contribute to.*
He was quiet for a moment.
He said: *you haven’t been asked yet.*
She said: *I know. I’m saying it anyway.*
He looked at her.
She looked back.
She said: *I’m here for another ten days. What else do I need to see.*
He said: *Rosa will take you to the watershed management site on Thursday. That’s the most significant piece of the management infrastructure.* He paused. *There’s a section in the northwestern quadrant that has old-growth characteristics you haven’t documented yet.* Another pause. *And Henrique wants to show you the community’s archive.*
She said: *the community has an archive.*
He said: *forty-three adults with two-hundred years of continuous territorial memory, plus the written records going back to 1847.* He almost smiled — she was starting to recognize his version of it, the controlled version that arrived at the edges and didn’t fully deploy. *The community’s archive is more complete than anything in the regional scientific database.*
She said: *when.*
He said: *when Rosa says.* He looked at the screen. *Probably Saturday.*
She said: *good.* She picked up her notebook. *I’m going to write up the otters before dinner.*
He said: *there are photographs in the station’s archive from the parents’ first year in the territory. I’ll pull them for the documentation.*
She said: *that’s six years of longitudinal data.*
He said: *yes.*
She stood up and then stopped.
She said: *how long were you going to be able to do this alone.*
He looked at her.
She said: *the station, the interface, the documentation. Managing the scientific record that protects the territory. How much longer could you have done it by yourself.*
He said: *I wasn’t doing it alone. The community—*
She said: *you were the only person who crossed the boundary.* She looked at him. *The interface is you. Everything that connects this community to the outside scientific world is you. You have been doing that for thirty years.* She paused. *I’m asking how much longer.*
He was quiet for a long time.
He said: *I’ve been thinking about that for the last five years.*
She said: *and.*
He said: *and I’ve been thinking that the next phase needed someone from the outside who understood what was being built.*
She said: *the grant application.*
He said: *yes.*
She said: *you weren’t waiting for anyone in particular. You were waiting for the right framework.*
He said: *yes.*
She said: *and the 1847 records.*
He said: *and Henrique.*
She looked at him.
He said: *Henrique makes his own decisions about who gets the 1847 records.*
She thought about that.
She said: *all right.* She picked up her notebook. *I’ll write up the otters.*
She went to her quarters. He stayed at the data terminal and looked at the otter photographs from six years ago — the two adults, young then, establishing themselves in the eastern channel for the first time.
He thought: *she asked how much longer.*
He thought: *no one has ever asked that before.*
He thought: *thirty years and she’s been here twelve days.*
