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

r 2

% C

Grass

Biomass = 0.566 * % cover m-2

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

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
