For years, the Bradford pear, cherished for its ornamental value, has graced the landscapes of Upstate South Carolina. However, beneath its beautiful white blooms lies an ecological issue that demands attention.
Standing tall at 16 to 26 feet with a distinctive conical to rounded crown, the Bradford pear, with its oval, glossy dark green leaves and abundant white, five-petaled flowers in early spring demands attention. You cant miss them here in the upstate, they’re one of the earliest trees in bloom and they’re everywhere.
Bradford pears and their related cultivars have become invasive, outcompeting native species and forming dense stands in undisturbed areas. The proliferation is driven by the dispersal of fertile seeds, especially when different cultivars grow in proximity. While historically limited by intolerance to extreme cold, the warming temperatures due to climate change have facilitated their northward creep.
The Bradford pear has structural weaknesses. They grow fast, are prone to storm damage, and can split simply from the weight of their own limbs. They have dense foliage inhibiting grass growth and an unpleasant fragrance during flowering. Adding to the challenge is the species’ resistance to diseases like fireblight, making effective management difficult
South Carolina has taken decisive action by banning the sale of Bradford pear trees starting October 1, 2024, becoming the second state after Ohio to implement such a prohibition. Concerns about the tree’s weak structure, short life expectancy, and invasiveness prompted this move.
Clemson’s Response: Bradford Pear Bounty Program
In response to the invasive nature of Bradford pears, Clemson University, in collaboration with the SC Forestry Commission, has initiated the “Bradford Pear Bounty” program. This innovative initiative encourages property owners to exchange up to five Bradford pear trees for an equal number of free, healthy, native replacement trees. The program aims to reduce the spread of Callery pears and enhance the diversity of the urban landscape.
The Bradford Pear Bounty program is conducted at various locations in Upstate South Carolina, with scheduled events throughout the year. Property owners can actively participate by registering for these events and exchanging their Bradford pears for native replacement trees.

This not only contributes to a more sustainable and diverse ecosystem but also addresses the negative impact of invasive species on the environment.
While Bradford pears may have charmed residents with their aesthetic appeal, their ecological repercussions can not be ignored. South Carolina’s proactive ban and Clemson University’s Bradford Pear Bounty program offer a blueprint for communities to actively engage in mitigating the impact of invasive species.
