Abstract or Description

Witheringia solanacea is a flowering shrub common to the Pacific Slope of Central America, from Mexico to Bolivia. Known locations of W. solanacea in Costa Rica were compared to geographic data to generate a predicted habitat model. Elevation, aspect, slope, annual mean precipitation, distance to roads, and distance to streams were statistically analyzed to determine their relationship with W. solanacea .The elevation, precipitation, and distance to roads variables had the most significant influence over plant distribution and were incorporated into the habitat model.
