Eyes of the Forest by Ray Nayler

Eyes of the Forest by Ray Nayler (F&SF, May-June 2020) opens on a colony planet that has a distinct Deathworld vibe1 (i.e. it is inimical to human life), and sees Mauled by Mistake treating the wounds of her apprentice Sedef, who has just been attacked by a lashvine. However, once Mauled is finished applying the nanobot medical patches, Mauled tells Sedef that (a) she herself has also been badly wounded in the attack, (b) they are out of medical supplies, and (c) Sedef will have to go back to the depot and get more.
The rest of the story sees the inexperienced Sedef make her way to the depot before returning to treat Mauled. During her journey we see that the human settlers have colonised an exotic and brightly illuminated world where anything that isn’t brightly lit is food. Consequently, humans have to wear lightsuits to protect themselves on the surface. As Sedef makes her way to the depot we also learn something about the colony’s history, that most humans retreated underground after arrival, and now only wayfinders like Mauled and Sedef go out on the surface. Light relief is provided by flashback passages which limn the pair’s mentor/student relationship:

“We need to be at the depot before dark [said Mauled]. Changeover is the most dangerous time to be out. As the forest modulates its glow for sundark, any slight suit anomaly is particularly visible.”
“We learned that. And there are animals, [our tutor] Beyazit said, that specialize in hunting during changeover. Some of which no one has ever seen. Predators we haven’t even—”
“Predators?” Mauled by Mistake gave out an incredulous bark, followed by a stream of intricate profanity. Sedef had heard that the wayfinders had a whole second language of profanity so inventive it was almost unintelligible to others. She couldn’t understand all of this expression—something about Beyazit’s father being born in a quiver of nightwing penises? Could that be right?  p. 68

The subject of predators comes up again when the pair meet another wayfinder in a shelter:

“Beyazit is telling the prospects to beware of predators,” Mauled by Mistake said in the young man’s direction.
“Beyazit should start each day by eating a bowl of his own entrails,” the young man said without looking up. “He almost got me killed once.”
“Who of us has he not almost gotten killed?”
Later, over a cold dinner of nutrient broth and noodles Sedef had made and packeted herself, Mauled by Mistake said, “The first thing to understand is that there are no predators in the forest. This old word does not fit. Only the ignorant use it.”
“But death is always waiting,” Sedef protested. “The forest is filled with teeth.”
“Yes,” Mauled by Mistake said. “You know your recitations well. The forest is filled with teeth. Death is waiting. Always. And so on. But there are no predators. There are only scavengers. When they attack you, and they will—and when they kill you someday, which they likely will—it will be by accident.”
“But the suit lights are a defense against attack. They indicate we are dangerous.”
The young man released a stream of profanity involving something about Beyazit attempting to whistle through a mouthful of various parts of his relatives’ anatomy. “The suits don’t indicate we are dangerous: They simply indicate we are alive.”  pp. 69-70

(Mauled is supposed to be a woman, but it is hard to visualise this character as anything other than a grumpy, mansplaining, 50-year-old bloke.2)
The story (spoiler) comes to an exciting climax when Sedef realises that she won’t get back to where Mauled is before Changeover, when there is a chance that the arrival of sundark and its accompanying EMP (Electro-Magnetic Pulse) may knock out her suit lights . . . . This subsequently happens, and then a “puma” appears: Sedef’s solution to this terminal problem is ingenious, and provides the story with a neat pay-off line.
This is a hugely appealing story, particularly so for those attracted to old-school SF.
**** (Very Good). 5,650 words.

1. Deathworld by Harry Harrison (Astounding Science Fiction, January-March 1960).

2. Mauled can’t be a man because, of course, that would turn Mauled and Sedef’s relationship a dreadfully patriarchal one. And if you have both Mauled and Sedef as men there will be no women left in the story. The horror!
