Small clarification: Nibiria's webs were discarded into the compost. It was the plants that told her that Goh was approaching. Because she takes care of them, they warn her of danger in return. It's an extension of her heritage magic. It's very hard to sneak up on her within her domain, as a result, unless you can understand the plants speaking.
Right, in the first post where Goh approached her property, when he stopped and slowly stepped over "something" it wasn't meant to be the webs she'd discarded, but a separate one around the border of her property rather than right up in her yard. I was just assuming that, disliking people as much as she does and being protective of her secrets, that Nibiria would have some kind of security around---such as a "trip wire" web that she'd feel when someone stepped on it or brushed past it or whatever. It was my attempt at a small IC detail to continue foreshadowing Goh's "clearly not a regular old man" vibes as well as the attempted comic relief of said old man sneaking up on the paranoid recluse. Now that he's failed, however, he'll just have to find another way, lol!
