Multiscale Analysis for Ecological Content and Context: What’s the Question? J. Michael Scott Senior Scientist, United States Geological Survey, Leader Idaho Cooperative Fish and Wildlife Research Unit, University of Idaho, Moscow, Idaho
Mike’s Version • What’s the niche segregation in Hawaii’s honey creepers? • Where do they forage? • How do they forage? • How do they spend their time?

“And NUH is the letter I use to spell Nutches, Who live in small caves, known as Niches, for hutches. These Nutches have troubles, the biggest of which is The fact there are many more Nutches than Niches. Each Nutch in a Nich knows that some other Nutch Would like to move into his Nich very much. So each Nutch in a Nich has to watch that small Nich Or Nutches who haven't got Niches will snitch.” Dr. Seuss, On Beyond Zebra, 1955

Median Size of National Wildlife Refuges by Ecoregion LEGEND >100,000 ha 10,000 to 100,000 ha 5,000 to 10,000 ha 1,000 to 5,000 ha < 1,000 ha No NW Refuges
Ecoregions with >1 percent of lands in USFWS National Refuge System Eleven ecoregions have 1% or more of the land in the NWR System. The Southern Florida Coastal Zone Ecoregion has the highest percentage with 3.7% in refuges. Southern Florida Coastal Zone
Ecoregions with no lands in USFWS National Refuge System Fifteen ecoregions have no National Wildlife Refuges
By Ecoregion… 8 ecoregions lack even one park with significant natural resources, 8 more are only represented once. 0 Subunits 1 Subunit >100 Subunits
Enough to Last?? Median subunit size in only two ecoregions is large enough to preserve the historic number of large mammals. > 314,000ha Based on Gurd et al. (2001) and Wiersma et al. (2004) minimum areas.

Potential Refugia in 2100 Only 34% of “significant natural resource” parks in the lower 48 are 95% certain to be in refugia. (Based on Griffith et al., unpublished model; Analysis by J. Roach)

309 refuges will lose waterfowl species as a result of range contraction. 220 refuges will gain or retain waterfowl species as a result of range expansion or stable range Pidgorna et al. unpublished data
Methods • The three Rs of conservation(Shaffer and Stein, 2000) • Representation = save one of everything • Redundancy =don’t put all your eggs in one basket • Resilience the ability to withstand adverse conditions

Where do we go from here? • Distribution of national wildlife refuge system in climate change refugiums? • Distribution of National Parks in ecological and geophysical space? • Ecological context of DOI lands?
What do we need to do? • Build a stronger research management partnership. • Work with climate modelers in regionalization of climate maps.
Enhanced partnership with USGS Land Trends Program • Combined social/economic and protected areas database • GAP related question using non traditional datasets such as: • Census datasets • TIGER files • Human footprint and GAP products
