  Citation × Citation Citation Abstract Copy Title: Rare Plant Associations, Oregon Dunes National Recreation Area, Sutton Recreation Area, and Heceta Sand Dunes ACEC/ONA Author: Christy, John A. Year: 2013 Nine of the ten rare plant associations identified in the dunes in 1993 are recommended for continued inclusion in conservation planning. Large-patch associations are currently in good condition, but small-patch associations are being infilled by a combination of plant succession and invasive species. Repeat photography using aerial and ground-based imagery is recommended as a way to gauge the rate of change in dune communities. Prescribed fire is recommended to monitor rejuvenation effects on two shore pine woodland associations that are most at risk of infilling. Vegetation mapping based on remote sensing will enable more accurate assessment of vegetation features, and facilitate modeling of management scenarios and effects of seal level rise, earthquakes, and tsunamis.

However, mapping the cultural services of those systems is more challenging. Human ecology mapping (HEM), which provides spatially-explicit depictions of the complex connections between humans and their environment, is an approach that can be used to improve understandings of the cultural services associated with landscapes. This atlas provides an overview of what HEM is and draws on experiences with a pilot project on the Olympic Peninsula in western Washington to illustrate what HEM data looks like and some of the ways in which it can be analyzed. Values and activity data were collected during 2010 and 2011 from 169 residents through a series of community workshops held on the peninsula. Density and diversity analysis indicated that the type of values and activities mapped as well as their spatial configuration and distribution differed depending on factors such as place of residence and gender. Values and activities were most strongly associated with national forest and state lands, and moderate to moderately steep terrain. The analyses exploring the relationship between values/activities and vegetation type and proximity to roads were inconclusive. Results from the pilot project indicated that HEM is not only useful for identifying where meaningful places and activities are concentrated, but also can help reveal important differences among subgroups as well as areas where conflicts in values and activities exist.

Year: 2010 The Oregon Silverspot Butterfly (OSB), Speyeria zerene hippolyta, is federally listed as “threatened.” It historically inhabited coastal regions of Washington, Oregon, and California (USFWS 2001). OSB populations only remain at five sites, four of which are in Oregon; one remaining population is in California, and none exist in Washington state as they have been extirpated (BFCI 2009; USFWS 2001). The site selected for this study was Rock Creek-Big Creek, adjacent to the Siuslaw National Forest (Figure 1) (Appendix 1). At this site OSB habitat is bisected by Highway 101; butterflies are observed to use both sides of the highway throughout their life cycle (P. Hammond, personal communication, June 12, 2009). It is suspected that vehicles on Highway 101, through collisions and their turbulence, present a substantial threat to OSBs at this site. This suspicion, however, has not yet been quantified and is only minimally evaluated in this paper. Effective mitigation techniques have rarely been developed and tested for small or flying organisms (but see, e.g., Smith 2009, Bard et al. 2002). Mitigation for one species may not work effectively for others (e.g., Jackson and Griffin 2000). Moreover, due to expense and scale, it is prohibitive to test multiple mitigation options sequentially. Therefore, we explored whether gathering targeted ecological data would help prioritize mitigation options for a threatened species, the Oregon silverspot butterfly (Speyeria zerene hippolyta, hereafter, OSB). We studied OSB ecology in order to evaluate the likely success of mitigation options before funding was pursued for implementing or directly testing any of them. In this research, we considered four potential management options that seemed most likely to be effective based on available information, including barrier installation; earthen berm removal and other actions to reduce the attractiveness of the road relative to the surrounding habitat; environmentally triggered, flashing speed-reduction-sign installation; and vegetation manipulation. Again, because these management scenarios are not yet in play, we could not directly test them. Rather, we gathered data on the behavioral ecology of OSBs and the environmental conditions of the road compared to surrounding habitat to determine which mitigation measures would have the greatest potential for effectiveness. To inform mitigation options we examined six questions about environmental conditions across habitats or microhabitats and how these correlated with OSB presence.
