Counties with Mapped NHI Occurrences

Catfoot (Pseudognaphalium micradenium), a Wisconsin Special Concern plant, is found in dry, commonly sandy soil, often in open oak and pine woods and barrens. Blooming occurs early-August through mid-October, fruiting early-September through late-October. The optimal identification period for this species is throughout September.

Catfoot is an erect forb, 10-100cm tall, and has an inflorescence covered in wooly hairs, and composed of disk flowers only. The numerous outer disk flowers are pistillate and the few inner ones are bisexual. Fruits are smooth achenes. Its leaves are alternate, toothless, wooly beneath, and more or less glandular hairy above, and the hairs are shorter and sparser than those on the stem.

It is distinguished from Gnaphalium obtusifolium by its stems with glandular, rather than wooly hair.

Blooming occurs early-August through mid-October, fruiting early-September through late-October.

Annual. The optimal identification period for this species is throughout September.

Associated species include Carex pensylvanica, Comptonia peregrina, and Andropogon gerardii.

Catfoot is found in dry, commonly sandy soil, often in open oak and pine woods and barrens.

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

Avoid locating landings, staging areas, or access routes in open sandy areas dominated by native grasses.

Because this plant is an annual, work may safely be conducted before the plants emerge or after they have developed mature seeds.

Prescribed burns and/or brushing may be beneficial, dependent on local site conditions and burn frequency. Rotational burns with annual unburned refugia may be preferred.

Minimize disturbance to hydrology, including soil disturbance from rutting.

Maintain low canopy cover areas for savanna and barrens plant species.

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.
