4 Forest Wetland A marsh or bog where the ground is full of water year-round.

5 Wetland Functions Flood water storage and filtration
Wildlife and plant diversity Fish and wildlife habitat Source: Washington State Department of Natural Resources, Wetland Field Guides, Managing Wetlands on State Forest Lands in Washington (2002).

6 Mature Forest Wetland Features
High-quality, keystone habitat; scores 70 or more on wetlands rating scale One-quarter acre or larger wetland; stands of at least two species of slow-growing, native trees Largest trees years old or have trunks averaging 21 inches in diameter Source: Washington State Department of Natural Resources, Mature Forest Wetland, Western Washington Wetland Rating System (2004).

7 Spawning, Fawning, Breeding & Nesting

Sources: Ann Eissinger, City of Bellingham Wildlife and Habitat Assessment (1995); Washington State Department of Wildlife, Management Recommendations for Priority Species (1997).

8 Keystone Habitat Large forest wetland 80-100 years old
Supports specific plant & animal life Part of larger wildlife corridor Source: Dr. John McLaughlin, Ph.D. Educational Values of Preserving Chuckanut Ridge: Benefits to Western Washington University (2006).

9 Vernal Pool Temporary Various sizes No fish

10 Vernal Pool Life Cycle Vernal pools appear
and provide homes for distinct water-dependent creatures. Seasonal rains flood forest floor. Required Objects: WordArt, Custom Animation, Diagram, Text Boxes Vernal pools evaporate and dormant eggs hatch in the following rainy season.

12 Female Fairy Shrimp Holds fertilized eggs Drops egg sack
Eggs lay dormant in dry season Eggs hatch in wet season Photo Source: The Vernal Pool Association, Obligate Vernal Pool Species (1990).

13 Indicator Species Crustacean: Freshwater Fairy Shrimp Bird: Western Tanager Amphibian: Long-toed Salamander The presence or absence and condition of these “obligates” indicates what kind of ecosystem it is and how well it is functioning.

14 Testing Shrimp Eggs for Toxins
Toxicologists analyze the adverse effects of chemicals on living organisms and determine how likely they are to occur. Brine Shrimp Eggs Hatching Photo Source:

19 A Parting Thought … Why should we be concerned about a crustacean that is less than an inch long, and will never be abundant enough to serve on top of a pizza? Source: Larry Serpa, Region 7 Area Ecologist, The Nature Conservancy (2006).

20 In the Words of Larry Serpa, Ecologist The Nature Conservancy:
Freshwater fairy shrimp occupy a role no other wetlands creature can fill. “When you rip an important strand out of a food web, there’s no way to know how much damage will be done.” Source: The California Freshwater Shrimp: A ghost-like crustacean we can’t afford to lose (2006), http//

21 The shrimp’s presence or absence can tell us a lot about the health of our wetlands.
“They are mute witnesses to the condition and history of the (wetlands) they inhabit. Continually bathed by the water, they must face whatever flows toward them. Pollution, siltation, introduced species, and other factors will affect them to some extent.”

22 “We will have lost much more than just the shrimp.”
If freshwater fairy shrimp disappear, we can be sure something detrimental has happened to the environment. “We will have lost much more than just the shrimp.”
