Dark-brown Sedge (Carex atrofusca)

The text provided mentions several species of sedges, with a particular focus on characteristics like color variations and associated habitats. This information primarily revolves around their importance as food sources for fish and their role in ecological contexts, particularly in wetland and alpine environments.

Considerations for Pets

  • Several sedges mentioned have dark brown to purple fruits (perigynia) that are eaten by animals, although the text does not explicitly state whether these are safe or toxic for pets.

Considerations for Children

  • The text mentions sedges having dark-brown glumes and bristle-tips. While not explicitly sharp, these features should be observed carefully if children are exploring areas where sedges grow.

Distribution and Habitat

  • Carex atrofusca is found in northern portions of Vermont, New Hampshire, and Maine.
