Land use conversion potential is a primary factor in the selection process for prioritizing critical conservation lands."

By assessing the land use threats facing species and/or ecosystems we can assist land managers in preserving biodiversity into the future and prioritizing at-risk lands for new protected land acquisition."

     "text": "We analyzed scenario-based land-use conversion threats from logging, agriculture, and development near existing protected areas. A conversion threat index (CTI) was created to identify ecoregions with highest projected land-use conversion potential within closest proximity to existing protected areas."

   {
     "@type": "TextObject",
     "text": "Land-use intensification poses significant threats to biodiversity both directly through the alteration and fragmentation of ecosystems and habitat loss, and indirectly through the disruption of supporting ecological processes. While protected areas offer refugia for species and ecosystems, they do not function in isolation from surrounding natural, working, or human-dominated landscapes."

   {
     "@type": "TextObject",
     "text": "Our goal was to identify, at the ecoregion-level, protected areas in close proximity to lands with a higher likelihood of future land-use conversion. Using a state-and-transition simulation model, we modeled spatially explicit (1 km2) land use from 2000 to 2100 under seven alternative land-use and emission scenarios for ecoregions in the Pacific Northwest."

     "@type": "TextObject",
     "text": "Our analysis indicated nearly 22% of land area in the Coast Range, over 16% of land area in the Puget Lowland, and nearly 11% of the Cascades had very high CTI values. Broader regional-scale land-use change is projected to impact nearly 40% of the Coast Range, 30% of the Puget Lowland, and 24% of the Cascades (i.e., two highest CTI classes). A landscape level, scenario-based approach to modeling future land use helps identify ecoregions with existing protected areas at greater risk from regional land-use threats and can help prioritize future conservation efforts."
   },
   {
     "@type": "TextObject",
     "text": "Our landscape level approach is useful given the magnitude and impact of human landscape alteration in the western United States and the limited time and resources available to enact effective management strategies at broader scales. Species level analyses of land use impacts are extremely useful at the individual level, however they are costly to implement and challenging to integrate into ecosystem level planning efforts. In contrast, landscape level land use scenarios can be used to quickly identify areas with a high probability of land use conversion and subsequent declines in ecosystem reserves and habitat area."
