Abstract
Objectives
Our primary goal is to identify sugar pine trees that are both resilient to drought and resistant to WPBR. To achieve this goal, we will complete the following objectives:
- Conduct field work to extract sugar pine cores. During summer 2025, we will extend core extractions that began in 2024 in YOSE and SEKI. Specifically, we will implement a paired study design to extract cores from infected and uninfected individuals, as well as individuals tested for WPBR resistance in 2024 and 2025.
- Test for drought resilience. In fall-spring 2025-2026, we will conduct tree-ring, resin duct, and stable isotope analyses. This compressive drought resilience assessment will be implemented in the Dudney Lab at UCSB.
- Support field-based cone collections. During the summer, 2025, students from UCSB will assist Ancient Forest Society (AFS) with the second year of cone collections by helping them locate trees with potential resistant to WPBR based on field observations. These cones will then be tested for genetic resistance.
- Develop maps of drought and WPBR-resistant sugar pines. The Dudney Lab will develop spatial maps of potentially WPBR-resistant trees and drought-tolerant trees within Yosemite and Sequoia National Parks to support future cone collections and tree plantings.
