Conifer Plantation

Need a main photo for this community

Definition

General natural community overview

Conifer Plantations make up a significant part of the forested landscape and receive a high degree of management emphasis. Conifer Plantations encompass a variety of conifer species, primarily red pine and white pine (Pinus resinosa and P. strobus), but also may include jack pine (Pinus banksiana), white spruce (Picea glauca) and tamarack/larch (Larix laricina). They are not a tracked natural community by the Natural Heritage Inventory (NHI), but are described here to present a more complete picture of forest types in Wisconsin, as well as to illustrate how managers can increase habitat suitability for a greater variety of species within Conifer Plantations if desired.

Conifer Plantations generally are associated with few Species of Greatest Conservation Need (SGCN), though they can be used by some species, depending on tree size, density, and landscape context. Plantations differ significantly in the composition of secondary species (other non-target trees, shrubs, and herbaceous plants) depending on site history, site preparation, and management regime, and may range from very low to moderate diversity. In general, high floristic and structural diversity is associated with higher animal diversity.

On dry sites, very young jack pine or red pine plantations may resemble Pine Barrens structurally. However practices such as the use of herbicide on competing vegetation reduces floristic diversity and limits usage by SGCN otherwise associated with Pine Barrens. Occasionally, conifer plantations on dry sites may fail (in part or completely), producing longer-term barrens-like structure with potential to provide habitat to barrens-associated species (e.g., Kirtland's Warbler).

Landscape context is important for many SGCN that use conifer plantations for at least part of their life cycle, with some preferring stands in close proximity to other forest or savanna habitats (e.g., Northern Dry Forest, Pine Barrens, or Oak Barrens). As conifer plantations mature past normal rotation age they may develop habitat attributes similar to late-seral Northern Dry-mesic Forest or Northern Dry Forest and support SGCN more typically found in those forest types. Examples include nest trees for goshawk or winter habitat for spruce grouse. Management on conifer plantations is a potential source of impact to SGCN and their habitat, but the nature and intensity of management in turn determines the nature and extent of the effect. Herbicide use when establishing plantations can be detrimental to plant and animal species. In addition, furrow and trench planting at least temporarily disturbs groundlayer grasses, forbs, and associated SGCN. Use of established best management practices and integrated approaches increases the role of conifer plantations as potentially suitable habitat for SGCN, and additional research and monitoring will continue to improve habitat over the long term.

Rare plants

The Natural Heritage Inventory has developed scores indicating the degree to which each of Wisconsin's rare plant species is associated with a particular natural community or ecological landscape. This information is similar to that found in the Wildlife Action Plan for animals. As this is a work in progress, we welcome your suggestions and feedback.

Scores: 3 = "significantly associated," 2 = "moderately associated," and 1 = "minimally associated."
Scientific Name Common Name Score
Asclepias ovalifolia Dwarf Milkweed 1
Vaccinium cespitosum Dwarf Bilberry 1

Landscapes

The following Ecological Landscapes have the best opportunities to manage for Conifer Plantation, based on the Ecological Landscapes of Wisconsin Handbook.



Major (3 on map)
A major opportunity for sustaining the natural community in the Ecological Landscape exists, either because many significant occurrences of the natural community have been recorded in the landscape or major restoration activities are likely to be successful maintaining the community's composition, structure, and ecological function over a longer period of time.

Important (2 on map)
Although the natural community does not occur extensively or commonly in the Ecological Landscape, one to several occurrences do occur and are important in sustaining the community in the state. In some cases, important opportunities may exist because the natural community may be restricted to just one or a few Ecological Landscapes within the state and there may be a lack of opportunities elsewhere.

Present (1 on map)
The natural community occurs in the Ecological Landscape, but better management opportunities appear to exist in other parts of the state.

Threats/Actions

Wisconsin Wildlife Action Plan graphic

What are conservation actions?

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 WWAP because lack of information can threaten our ability to successfully preserve and care for natural resources.
