WHAT IS A BIO-BLITZ?
• An intensive biological survey to develop a baseline inventory. • Much like Nature Mapping, but with more intense searching for taxa groups (botany, mammals, birds, reptiles/amphibians, inverts) and cataloguing them as they are discovered. • This survey lasted 6-hours. • Accomplished in two 3-hour phases.

HOW WAS IT ACCOMPLISHED?
• ORGANIZATION PARTNERS, Nisqually Stream Stewards, Nisqually Land Trust, Northwest Trek, Tacoma Nature Center.
• FUNDING (USF&WS Connecting People With Nature.
• TAXA-TEAM LEADERS (Jake Pool, NWT Botany; Mary Sue Gee, Botany; Chris Hoff, birds; Les Mead, amphibs/reptiles; Mallory Clark, mammals)
• VOLUNTEER HELP (30+ volunteers)
• CONVENIENT SCIENCE-CENTRAL FACILITY FOR PLANNING AND PROCESSING OF INFORMATION.

• ESTABLISH DATABASE PRIOR TO RE-MEANDER CONSTRUCTION OF OHOP CREEK.
• NO PRIOR TAXA DATABASE ESTABLISHED AT LOWER OHOP VALLEY
• NEED TO BEGIN CATALOGING PRESENCE OF TAXA IN LOWER OHOP VALLEY.

“In the Puget Sound lowlands, the first Western Trillium flowers coincide with the Robins’ first songs. Also known as the Wake Robin, it may be that the flower wakes the bird, or perhaps the other way around. Research shows that bird song may impact and even be necessary for the opening of blossoms. According to accounts, flower buds remained unopened in some orchards where heavy pesticide use had eradicated birds. After broadcasting recordings of bird songs in these orchards, the buds opened.”
Quote from: Medicine of Place, by Olympia residents Julia Brayshaw and Karen Lohmann.
