Quercus shumardii

Description

Shumard oak (Quercus shumardii) is a large, deciduous tree that reaches up to 30m in height. It has gray, furrowed bark and grayish-brown, dull, bud scales on the mature branchlets. The leaves are alternate and deeply lobed. Each leaf has seven to nine sharply toothed lobes that tend to widen slightly toward the tip. The 10-18cm leaves are dark green above, and paler green below with hairs clustered in the leaf axils.

Rank Justification

Imperiled in the nation or state because of rarity due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors making it very vulnerable to extirpation from the nation or state.

PABS

The PA Biological Survey considers Shumard oak to be a species of special concern, based on the relatively few occurrences that have been confirmed. It has been assigned a rarity status of Endangered.

Habitat

The species grows in moist to wet woods along streams, bottomlands, and lower slopes, often on calcareous substrate.

Survey Dates

Fruits September - October

Distribution

In Pennsylvania, it has been found in the south-central and northwestern counties.

Management

Maintenance of known populations and preservation of the communities where Shumard oak grows will be crucial to its survival. Creating buffers around fragmented habitat and removal of invasive species will help to maintain populations and encourage new population growth. The management of the known sites requires long term monitoring of populations. Potential sites for restoration should be evaluated.
