Data layers
-----------------
Refugia layers represent mid-century (2041-2070) and end-of-century (2071-2100) conditions for the SRES A2 emissions scenario at 4-km resolution
-----------------
Combined index for 53 species (clipped to Brandt's boreal region):
_refbrandt53_YYYYZZZZ
Species-specific indices:
XXXX_refYYYY
where:
YYYY = Time period (2050s or 2080s)
ZZZZ = weighted or unweighted
XXXX = Songbird Species Code (see Birdlookup.csv)
