INSTRUCTOR: Dave Pehling, Extension Assis- tant, WSU Cooperative Extension Snohomish County PROGRAM OVERVIEW: Landscape professionals experienced in diagnosing and managing insect nd disease pests are often less prepared to roperly manage vertebrate pests in the land- scape. This program will review identification of pests by the types of damage caused, and include discussions on pest habits and a variety of management strategies. Pests to be discussed will include moles, voles, deer, rabbits, squirrels, mountain beaver, raccoons, rats, opossums and Canada geese. This program is designed for entry to intermediate level professionals.

PROGRAM OVERVIEW: Learn to identify fre- quently encountered fall perennial and winter annual landscape weeds using fresh and dried specimens, and reference slides. This program will include discussions of cultural (including design considerations), biological and chemical management strategies, including a review of products, restrictions and other issues.

Preservation of trees on public property is becom'^^in important issue with demolition of existing houseSPid the construction of new homes on existing lots. In the Chicago area, Glencoe, Highland Park, Park Ridge, Winnetka and others have experienced this redevelop- ment process. Glencoe as a case study offers us an insight into steps that can be taken to preserve estab- lished parkway trees from construction damage. This article describes how to structure the bureaucracy of municipal government to successfully preserve street trees in older established towns or neighborhoods.

Short and Long-Term Effects of Treeshelters on the Root and Stem Growth of Ornamental Trees The Journal of Arboriculture 23(2): 49-56. March, 1997. Short-term (aerated solution culture and container nurs- ery) and long-term (landscape) experiments were con- ducted to study the effect of treeshelters on the root anc shoot growth of several ornamental trees ( Sequoia sempirvirens, Quercus lobata, Quercus agrifolia, Lagerstroemia indica ‘Watermelon Red’, Ginkgo biloba, Platan us race m os a, Fraxinus latifolia, and Populus euamericana). In general, plants grown in tree sf^^s were taller and had some reduced caliper growth. ITreeshelters reduced top dry mass of F. latifolia, P. racemosa, Q. agrifolia, Q. lobata, and P. euamericana and also reduced root dry mass, root:shoot ratio, total root length, and total root area for all species/cultivars except Q. agrifolia. The results are explained on the basis of the microenvironment in/around tree shelters, photo- synthetic partitioning and immobilization of plants growing in shelters. Management challenges and potential usefulness of treeshelters in landscape transplanting are also discussed. as part of an ongoing process of compilation, evaluation, and refinement, evolving to reflect new ideas and evolving concepts of care. Ideas for approaches to design, including consideration of maintenance issues are provided. Guidelines for Designing Healing Gardens Mara Eckerling. Journal of Therapeutic Horticulture 8: 21-25. 1996. Design Considerations for the Development of Therapeutic Gardens David Camp. Journal of Therapeutic Horticulture 8: 6-11. 1996. Recommendations discussed in this paper seek to explore basic design qualities that enhance and enrich the experience of nature. With new gardens being built, expanding our opportunities for research, these considerations should be seen ProHort Seminar Registration Vertebrate Pest Management Weed ID & Management For this paper, a healing garden is defined as a garden in a healing setting designed to make people feel better. The ideas for what should be in the garden are taken from historic precedent, clinical studies, literature, interviews with design- ers, and existing guidelines. The prime consider- ation for designing the space is the emotional state, or how a person would feel while in the space. A “methodology” is presented, organized in layers. The first layer incorporates the spirit of the place, or what makes a place unique. The second layer includes the physical requirements to make a garden work within a particular setting. The final esoteric layer involves the fine tuning neces- sary to involve all of a person’s senses while in the garden. $15 $17 TOTAL: $. Group Rates: 5 or more persons, less 20%.

Biocontrol agents for mites are an important part of the commercial insectary business. There are over 50 commercial suppliers of predatory midges for controlling mites. This article reviews information a user must consider when selecting a particular predatory mite and sup- plier. A review of mite midge biology, life cycle, enemies, and commercial availability are provided.

IPM on Golf Courses IPM Practitioner 19(4): 1-7. April, 1997. Intensive applications of insecticides, herbicides, fungicides, and synthetic fertilizers are often used to maintain the picture perfect quality of fairways and greens. Many golf course superintendents would like to make a change to a more environ- mentally friendly maintenance regime. In this article are shared IPM methods being used by some managers. These include using such strate- gies as degree day models, monitoring of biologi- cal activity, indicator plants, testing, scouting and monitoring, and pest trapping. A review of suc- cessful alternative disease control strategies, cultural methods, fertility and irrigation programs and more are presented.
