anthropologist Elizabeth Colson in an interview that “Now there are lots <strong>of</strong> trees on the [<strong>Ozette</strong>] marsh<br />
because nobody takes care <strong>of</strong> it anymore.” In 1981, Stephen Underwood, <strong>Ozette</strong> Subdistrict Ranger, wrote<br />
<strong>Olympic</strong> <strong>National</strong> <strong>Park</strong> visitors to solicit early photographs <strong>of</strong> the Ahlstrom’s Prairie. He received slides<br />
and prints <strong>of</strong> Ahlstrom’s Prairie from the early 1960s. He wrote the visitors thank you notes saying in one<br />
letter that “It’s impressive how much growth has occurred out on the prairie [between the early 1960s and<br />
1981]” (Underwood 1981). Wetlands ecologist Linda Kunze documented tree encroachment on the <strong>Ozette</strong><br />
<strong>Prairies</strong> in her unpublished botanical field notes in 1989 (see Appendix 1). Ed Tisch (2002:6) explained the<br />
tree encroachment onto Ahlstrom’s Prairie in an article in the Voice <strong>of</strong> the Wild <strong>Olympic</strong>s magazine:<br />
<strong>The</strong> highest, best-drained sites favor tree establishment. Most <strong>of</strong> these elevated areas<br />
currently support a hemlock\salal-evergreen huckleberry community type in which<br />
bracken, deer ferns, bunchberries, twinflowers, and beaked mosses are common, and<br />
the dominant shrubs grow to heights <strong>of</strong> three to ten feet. <strong>The</strong>se expanding ‘forests’ are<br />
slowly repossessing.<br />
In a faculty-reviewed geography master’s thesis using aerial photos, Kate Ramsden (2004) esti-<br />
mated that Roose’s Prairie decreased in size by 32.7 percent between 1964 and 2000 and that Ahlstrom’s<br />
Prairie decreased in size by 53.5 percent during the same 36-year interval. Emil Person, a long-time<br />
resident <strong>of</strong> the western Peninsula who has watched the trees encroach over the years, estimates an even<br />
