Baseline and predicted future climate niches of Sitka Spruce (Picea sitchensis) based on three general circulation models and two emission scenarios

This package contains 13 polygon layers representing baseline and predicted future climate niches (2050s & 2080s) of Sitka Spruce (Picea sitchensis). The modeling algorithm Maxent and the Worldclim predictor set have been used to compute niche projections under two emission scenarios (A1B & A2A) based on three general circulation models (CSIRO, CCCMA & HADCM3). The shapefiles are derived from gridded model outputs with a grid cell resolution of 30 arc-seconds.

Modeled frequency and predicted range of sitka spruce under various climate scenarios

This dataset contains 8 layers showing current and predicted ranges of sitka spruce (Picea sitchensis ). One layer demonstrates range according to current climate conditions averaged from the period 1950-1975. Six layers model predicted ranges according to two different IPCC scenarios according to their Canadian Climate Centre modeling and Analysis (CCCma) third generation general correlation models (CGCM3) A2 and B1, in the years 2020, 2050, and 2080. An 8th layer shows a continuous model of predicted occurrence for the period 1975-2006.
