Similar Ecological Communities

This type can be very similar to the Northern Hardwood Forest type, which has less than 40% cover of black cherry in canopy, and typically has more sugar maple, ash, yellow birch, or sweet birch.

Black Cherry – Northern Hardwood Forest

Conservation Value

Pennsylvania is part of the core range for commercial black cherry production and has been referred to as the “black cherry capital of the world.” Nearly 30% of the total volume of black cherry is in Pennsylvania, and the growing conditions within the northwest and northcentral portions of Pennsylvania contribute to its high quality (State of the Forest Products Industry in Pennsylvania, 2020). The Black Cherry – Northern Hardwood Forest is common in the northern tier of Pennsylvania, especially the Northern Central Appalachians (Unglaciated Allegheny High Plateau) and has been documented in the Central Appalachian and Ridge and Valley regions.

 

Following timber harvest, this type may establish on ridgetops that were formerly occupied by oaks. Rarely, this community supports state-listed plants (such as the great-spurred violet, Viola selkirkii). A number of bird species that prefer forest interior conditions will occupy Black Cherry – Northern Hardwood Forests, including the ovenbird (Seiurus aurocapilla), red-eyed vireo (Vireo olivaceus), and scarlet tanager* (Piranga olivacea; National Audubon Society/PNHP 2017). Other breeding bird species that utilize Black Cherry – Northern Hardwood Forests include the indigo bunting (Passerina cyanea), rose-breasted grosbeak (Pheucticus ludovicianus), and white-breasted nuthatch (Sitta carolinensis; Sargent et al., 2017).

Threats

While there are no short-term conservation risks for the Black Cherry – Northern Hardwood Forest at this time, this type could experience significant changes to the composition or distribution in a changing climate. Research suggests that species that are currently dominant in our Black Cherry – Northern Hardwood Forests, such as sugar maple, eastern hemlock, and red maple could become less common in both high and low emissions scenarios. Black cherry specifically is known to be resistant to drought and is expected experience an increase in range with climate change (Iverson et al., 2008; Peters et al., 2020). Forest pests/pathogens could significantly impact tree species in this community type, including eastern tent caterpillar (Malacosoma americanum) and the cherry scallop shell moth (Hydria prunivorata), hemlock wooly adelgid (HWA; Adelges tsugae), and beech bark disease. Invasive plant species such as garlic mustard (Alliaria petiolata) and Japanese barberry (Berberis thunbergii) threaten the viability of the Black Cherry – Northern Hardwood Forest.

 

Throughout much of its range, the Black Cherry – Northern Hardwood Forest community type has experienced forest fragmentation from roads, shallow gas development, and habitat conversion. Furthermore, the core range of Black Cherry – Northern Hardwood Forests overlaps with the shale gas region in Pennsylvania, West Virginia, Maryland, and New York. Continued development of the shale gas region, specifically the Marcellus Shale, may result in additional fragmentation throughout the Black Cherry – Northern Hardwood Forest range in Pennsylvania. Edge habitats created by forest fragmentation increase the risk of invasion from non-native species and decrease wildlife habitat for species requiring continuous forest blocks.

Management

Black Cherry – Northern Hardwood Forests can be sustainably managed; however, forest conditions may require a specific plan to achieve management goals. Private landowners can consult with service foresters at the Pennsylvania Bureau of Forestry for more information on sustainable forest management practices that are best suited for their property. Management of invasive species is encouraged, and management of white-tailed deer could improve forest regeneration in forests experiencing high levels of herbivory.
