Current Research

  • Testing the efficacy of seed zones for re-establishment and adaptation of bluebunch wheatgrass (Pseudoroegneria spicata).
  • Dispersal rates of forage kochia (Bassia prostrata) from seeded areas in southern Idaho.

Research Interests

Jessica has interest in landscape genetics, distribution and migration of native plants, plant community restoration, and invasion ecology.

Past Research

Much of our understanding of plant species ranges, habitats and diversity originates from specimens housed in local and regional herbaria. In recent decades, specimen collecting has been on the decline, leading to an increasing reliance on older material. For her masters thesis, Jessica completed a comprehensive floristic inventory of east-central-Idaho, documenting 1,349 unique taxa and one species new to science. In this project, she developed data management methods to capture location and ecological information with greater precision and accuracy than past inventories. A total of 11,237 of specimens were contributed to the Rocky Mountain Herbarium through this project.
