Counties with Mapped NHI Occurrences

Fly Honeysuckle (Lonicera involucrata), a Wisconsin Endangered plant, is found in cold, wet old-growth tamarack swamps, alder thickets, and cold moist woods. Blooming occurs throughout June, fruiting throughout August. The optimal identification period for this species is early-June through August.

 
 
 

Fly honeysuckle is a shrub with 10-15mm-long yellow, tubular or cup-shaped flowers with a red "saucer" base, stems are 2-4cm long. The red flower is base made up of oval leaf-like bracts and usually stays attached after the petals have dropped. Its fruits are shiny, purplish-black (at maturity) and develop in the red base of the flower. Its leaves are opposite, the largest are 9-12+ cm long, egg-shaped, gradually widening from a short petiole and concavely forming a sharp point at the tip, the undersides have shaggy, long, soft hairs.

Blooming occurs June to early-July, fruiting July through mid-August.

Perennial. The optimal identification period for this species is early-June through late-August.

Associated species include Larix laricina, Alnus rugosa, Calamagrostis canadensis, Calla palustris, Ribes triste, Potentilla palustris, Caltha palustris, Sium suave, Galium tinctorium, and Carex canescens.

Fly honeysuckle is found in cold, wet old-growth tamarack swamps, alder thickets, and cold moist woods.

Avoid locating landings, staging areas, or access routes on or near known populations.

Avoid broadcast spraying of herbicides and use care with spot spraying.

Minimize disturbance to hydrology, including soil disturbance from rutting.

Maintain and restore open habitat through selective clearing and brushing.

Species of Greatest Conservation Need (SGCN) are associated with habitats (or natural communities) and places on the landscape. Understanding relationships among SGCN, natural communities and ecological landscapes help us make decisions about issues affecting SGCN and their habitat and how to respond.

Conservation actions respond to issues or threats, which adversely affect species of greatest conservation need (SGCN) or their habitats. Besides actions such as restoring wetlands or planting resilient tree species in northern communities, research, surveys and monitoring are also among conservation actions described in the Wisconsin Wildlife Action Plan because lack of information can threaten our ability to successfully preserve and care for natural resources.
