Table 2 Regression equations and r 2 values used to calculate grass, black sagebrush, live PJ and dead PJ biomass and the percent carbon (C) within each plant type for determining kilograms of C

From: Twentieth century carbon stock changes related to Piñon-Juniper expansion into a black sagebrush community

Plant type Model r 2 % C
Grass Biomass = 0.566 * % cover m-2 0.96 40.84 (0.41)
Black sagebrush Biomass = 12.132 * % cover m-2 0.90 45.55 (0.51)
Live Piñon Biomass = 11.41 * (RCD * 0.1)^2.6664) NA 46.14 (0.43)
Juniper Biomass = 8.256 * (RCD * 0.1)^2.8058) NA 45.64 (0.54)
Dead Piñon Biomass = (Live Biomass - (1.853 *(RCD * 0.1)^2.0268)) NA 46.14 (0.43)
