North Carolina › Salicaceae › Salix
Coastal Plain Willow
Native. The Salix genus feeds 285 caterpillar species in NC, draws 39 bee species in the Southeast, including 16 pollen-specialist bee species that depend on it,; 9 bird species have recorded feeding interactions with this genus in North America. Strong for caterpillars, bees, specialist bees and birds. Adjusted -2 because this species is less common in NC than others in its genus.
Insect resources, birds and habitat
Bars show recorded counts on a linear scale. Each category runs from zero to its largest count in this NC plant catalog; the same scale applies across plant pages. Compare plants within a category, not bar lengths across categories. Zero records may mean missing research. Growth form is shown as text.
Additional insect evidence
Bar length follows recorded-name count on the displayed scale, not ecological importance. Unknown is not zero support. Flower visits do not confirm feeding or pollination. Named insects may include historical or unresolved names.
Provisional additional insect credit: +0 (maximum 5). Scoring rule and limitations. Study references and interaction records are included in this plant’s data record.
