Our goal is to increase value to landowners by creating highly productive forests. We rigorously test the trees and select elite individuals that offer the greatest potential, all the while maintaining genetic diversity for future breeding generations. https://images.squarespace-cdn.com/content/v1/53d80341e4b04ced59322afa/1599053488334-4BKFBT9IOGB5EUCMF066/PRS+Calibration.jpg.png Home - Genetics Matter Forest landowners should always plant adapted families of loblolly pine (Pinus taeda) that have appropriate levels of genetic improvement for volume growth or productivity, disease resistance, with desirable stem form and wood quality. We developed the Loblolly Pine Performance Rating System (PRS™) as a service to landowners, nursery managers, the tree improvement community, and loblolly pine breeders. PRS™ expresses the genetic potential of a family for stem volume production, resistance to fusiform rust disease, stem straightness. https://images.squarespace-cdn.com/content/v1/53d80341e4b04ced59322afa/1555103998580-I0JJZHSRSYS5NTNOEF64/IMG_20180807_080914408.jpg Home - RESEARCH Applied research is the foundation of our success. It enables us to improve the efficiency and effectiveness of our tree breeding processes. Key focus areas include seed orchard management, controlled pollination methodology, quantitative genetics and molecular marker technologies.

In return, they are able to utilize the knowledge and advanced genetic material developed within our Program. Our membership base is wide, ranging from vertically integrated forest products companies, state agencies, TIMOs, REITs, tree nurseries, land consultants and biotech companies. Contact us to see what membership option will best suit your business needs. https://images.squarespace-cdn.com/content/v1/53d80341e4b04ced59322afa/1570220910592-WO0NAIXZ1SEWMJL9JXJ7/TIP+Students.jpg Home - THE STAFF & STUDENTS The dedicated staff of the cooperative include NC State University faculty and full time staff. Through research and extension, these folks provide contributions to the scientific community as well as the greater forest industry. Our goal is also to extensively train both graduate and undergraduate students to become forest professionals in the classroom and the field. A varied group of backgrounds to support current and future forestry; sustainability in action! https://www.treeimprovement.org/contributing-membership daily 0.75 2025-07-01 https://images.squarespace-cdn.com/content/v1/53d80341e4b04ced59322afa/1597351831449-W1N3FLCBLZ3BA57BQLHC/Contrib+image.png Contributing Membership https://images.squarespace-cdn.com/content/v1/53d80341e4b04ced59322afa/1599861172793-05MMKZPRHMANQYNTAB9S/Bareroot+AJ.JPG Contributing Membership https://www.treeimprovement.org/research-associate-membership daily 0.75 2025-07-01 https://images.squarespace-cdn.com/content/v1/53d80341e4b04ced59322afa/1597355378157-R5FLW35ZN0Y1HKMXMZXG/IMG_9001.JPG Research Associate Membership https://www.treeimprovement.org/prs daily 0.75 2025-11-14 https://images.squarespace-cdn.com/content/v1/53d80341e4b04ced59322afa/1599861516997-PPEXBUPHW2VVBTU1HKM7/PRS+banner_2.png PRS™ https://images.squarespace-cdn.com/content/v1/53d80341e4b04ced59322afa/1599865108994-M1D89GK94ZRIQ1R83ZH8/PRS_Choice+Coastal+OP3_CCC_CP.png PRS™ https://images.squarespace-cdn.com/content/v1/53d80341e4b04ced59322afa/1599866149281-UOP1IT0NMD91CL1TULKG/prs_Superior+Coastal+OP7_CCC_CP.png PRS™ https://www.treeimprovement.org/tip-staff daily 0.75 2026-02-18 https://images.squarespace-cdn.com/content/v1/53d80341e4b04ced59322afa/fb4ad0e8-2b5b-4473-a208-7fcc8d5068d1/DSC_0738+%282024-04-10T22_29_40.416%29.JPG TIP staff & students https://images.squarespace-cdn.com/content/v1/53d80341e4b04ced59322afa/202b968a-866b-4579-a043-388e8fb421a2/2021-12-22-profile-photo2.jpg TIP staff & students https://images.squarespace-cdn.com/content/v1/53d80341e4b04ced59322afa/1594309196711-M0STLJQV717RUUHI942Q/Trevor_Walker.jpg TIP staff & students -
