September 16-17, 2014

University of Washington Botanic Gardens, Seattle, WA

Conference Mission Statement

Invasive plants are a significant threat to biodiversity and ecosystem function. New introductions continue to emerge through a variety of pathways and vectors, while existing invaders continue to persist and expand their range. Changes in climate, land use, and biotic interactions present new challenges in controlling the spread of these invaders. Land managers and scientists will hear the latest information on how to effectively prevent, detect, and respond to these persistent and emerging threats. Conference presentations, both invited and contributed, will stimulate dialogue, raise new questions and offer innovative solutions. Participants from throughout northwestern North America will contribute ideas and meet colleagues for collaboration.

Keynote Speakers:

September 16 – Daniel Simberloff, University of Tennessee
September 17 – Jason S. McLachlan, University of Notre Dame

October 15th, 2014
University of Washington Botanic Gardens Center for Urban Horticulture

Up by Roots is a one-day workshop on October 15 that highlights the principles of soil science and their use in facilitating the growth of healthy trees and developing water efficient landscapes. Healthy soils absorb and hold water and nutrients needed to grow long-lived trees. These same soils retain runoff and preserve water at the site, reducing the need for irrigation and limiting potential impacts on nearby water sources.

This is a hands-on workshop that includes lectures and field work intended to introduce the underlying scientific principles guiding tree biology and soil-water relations. It is only through a healthy respect of these guiding principles, that one can effectively design, install, and manage soils and trees in the urban landscape.

James Urban, FASLA, ISA is a landscape architect with over 30 years of experience in the field of urban development. This workshop combines Jim Urban’s extensive experience with contributions from local experts to address regulations and conditions specific to our area.

Presentations will be relevant to urban foresters, landscape professionals, consulting arborists, tree care professionals, urban planners, landscape designers, sustainability professionals, landscape architects, municipal managers, land managers, and planners.

Conference Mission Statement

We face an uncertain future – economically, politically, and climatically. Those concerned with managing, researching or protecting native plant communities, rare plants and their habitats need to be aware of these changes and have the necessary tools to effectively address them. We will have papers, both invited and contributed, that will engage all in a dialogue intended to raise questions and find solutions. Participants from throughout northwestern North America will contribute ideas and meet colleagues for future collaboration.
