Location of the Chequamegon-Nicolet National Forest and the northern Wisconsin stream network.

<p>Streams surveyed during fall for active beaver colonies on the Chequamegon-Nicolet National Forest. Targeted streams are in magenta and non-targeted streams are in green. The grey background for the stream network is the topography of northern Wisconsin as represented by a hillshade model. Weather data were obtained from the indicated National Weather Service Cooperative Observer Program (COOP) weather stations.</p

Weather models for beaver colony density on streams where no targeted beaver management occurred on the Chequamegon side of the Chequamegon-Nicolet National Forest, 1997–2013.

<p>Models listed are the minimum AIC model, competitive models (those models within 2 AC units of the 006Dinimum), and the 2007 drought model. The evidence ratio is the ratio of the Akaike weights for the minimum AIC model and an alternate model.</p

Historical Projections

HistoricalProjections -> HabitatSuitability hs1979-hs2013 are spatial layers that distinguish 32 ha cells in Michigan, USA as nonsuitable (0), low suitability (1), moderate suitability (2), and high suitability (3) habitat for Kirtland's warbler annually between 1979 and 2013. The layers can be used as input files for the Spatial Data subprogram in program RAMAS GIS. HistoricalProjections -> Precipitation p1979-p2013 are spatial layers that contain total March precipitation values for the Nassau NOAA station (Bahamas) annually between 1979 and 2013 in cells that contain suitable habitat for Kirtland's warbler. The layers can be used as input files for the Spatial Data subprogram in program RAMAS GIS

Beaver colony numbers/km by year for (a) trout streams without targeted beaver management and (b) trout streams with targeted beaver management for the Chequamegon-Nicolet National Forest.

<p>In panel (a), open circle = Nicolet trout streams, filled circle = Nicolet non-trout streams, open square = Chequamegon trout streams, filled square = Chequamegon non-trout streams. In panel (b), open circle = Nicolet side, triangle = Chequamegon side. Dotted lines are the predicted trends from generalized additive models (significant trends only).</p

Effort for aerial surveys of beaver colonies made October–November along four categories of streams in the Chequamegon-Nicolet National Forest, 1987–2013 (Nicolet side) and 1997–2013 (Chequamegon side).

<p>Targeted streams were subject to the beaver control program.</p

Time trend and weather models for beaver colony density on streams where no targeted beaver management occurred on the Nicolet side of the Chequamegon-Nicolet National Forest, 1987–2013.

<p>Models listed are the minimum AIC model, competitive models (those models within 2 AC units of the minimum), and the trend model.</p
