  Citation × Citation Citation Abstract Copy Title: Pine Creek Conservation Area: 2013 Mapping and Monitoring Report Author: Nielsen, Eric M., Noone, Matthew D., Kagan, James S., Lee, Matthew T. Year: 2013 Pine Creek Conservation Area (PCCA), just northeast of the John Day River in Wheeler County, Oregon, was acquired in 1999-2001 by the Confederate Tribes of Warm Springs with support from the Bonneville Power Administration (BPA), to mitigate for wildlife losses created by the large, hydropower Columbia River Dams, particularly the Bonneville, Dalles and John Day Dams. Many thousands of acres of grassland, shrub steppe and riparian habitats were lost due to inundation, and the objectives of the acquisition included restoration of similar habitats. As part of an interagency agreement created in 2002, the Oregon Natural Heritage Information Center established a baseline monitoring program in 2002. This effort included the establishment of permanent monitoring plots to allow for a detailed assessment of vegetation change in the plant communities occurring at the site. It also included the development of an existing vegetation map, hopefully to allow for an analysis of overall vegetation change across the conservation area. The map showed the distribution of western juniper, native grasslands, big sagebrush, and weed-dominated areas at the site. In the eight years since the original map was made, a series of management actions, including juniper clearing, prescribed fires, and riparian restoration activities have significantly changed the vegetation at PCCA. In the spring and summer of 2010, the Oregon Natural Heritage Information Center, now the Oregon Biodiversity Information Center at Portland State University, visited the area to assist the land manager in developing a strategy for meeting the information needs of the Tribes and BPA in evaluating the success of the first decade of restoration. This report details that effort, which incorporated a combination of field inspection, photo-interpretation, and remote sensing-based mapping to assess change since the establishment of the conservation area, to lay a new baseline against which to measure future change, and most importantly to provide detailed information useful for land management decision making in the continuing restoration efforts.

  Citation × Citation Citation Abstract Copy Title: Mapping Conservation Opportunity Areas for the Intertwine's Regional Conservation Strategy Author: Burcsu, Theresa, Kagan, James S. Year: 2011 As part of efforts to develop the Regional Conservation Strategy (RCS) for the greater Portland-Vancouver region, Oregon State University’s Institute for Natural Resources (INR) was asked to use spatial modeling to identify conservation opportunity areas (COAs). To complete the project, INR analysts proposed a strategy that would map high value areas using a landscape approach that is focused on relatively high spatial resolution data sets available for the whole metropolitan region. The approach creates 2 main metrics: one focused on terrestrial organisms and the other focused on aquatic and riparian organisms. These are combined to create a map of highly ranked land areas that can be used to formulate a map of conservation opportunity areas. The purpose of the COA mapping project was to use geographic information system methods to identify landscape patches with conservation and restoration potential. The criteria used to identify these high value patches was based on a number of base- and derived-data sets that we call “data inputs.” The data ranged from recently mapped land use and land cover types, hydrological data to indicate species habitat requirements, and road influence on habitat patches. The project identified some areas in which data gaps exist (e.g., region-wide biodiversity data collected and mapped in consistent ways) and some opportunities for improving existent data sets (e.g., land use/land cover map). The project provided several layers that can be used to guide the final Regional Conservation Strategy in selecting conservation opportunity areas. The best layer will depend upon the needs of the RCS efforts, however, in our opinion the most appropriate layer to use is COA 3.11.1 which weights wetlands fairly high, but not as highly as the second data draft. COA 3.10.1 offers similar results as well. Overall it appears that the model results corroborate corridors analysis done previously (Hennings and Soll 2010). There are some issues remaining that we feel can most adequately be addressed by updating the base land use/land cover map.
