The distribution of tree biomass carbon within the pacific coastal temperate rainforest, a disproportionally carbon dense forest

Spatially explicit global estimates of forest carbon storage are typically coarsely scaled. While useful, these estimates do not account for the variability and distribution of carbon at management scales. We asked how climate, topography, and disturbance regimes interact across and within geopolitical boundaries to influence tree biomass carbon, using the perhumid region of the Pacific Coastal Temperate Rainforest, an infrequently disturbed carbon dense landscape, as a test case. We leveraged permanent sample plots in southeast Alaska and coastal British Columbia and used multiple quantile regression forests and generalized linear models to estimate tree biomass carbon stocks and the effects of topography, climate, and disturbance regimes. We estimate tree biomass carbon stocks are either 211 (SD = 163) Mg C ha-1 or 218 (SD = 169) Mg C ha-1. Natural disturbance regimes had no correlation with tree biomass but logging decreased tree biomass carbon and the effect diminished with increasi..., , , # Data from: The distribution of tree biomass carbon within the pacific coastal temperate rainforest, a disproportionally carbon dense forest

## Description of the data and file structure

Spatial layers are presented in Alaska Albers Equal Area Conic (AEA) projection with a 30 x 30 m cell size. NOTE: the quantileRegresionForest::predict() function in R will only work when all spatial layers are provided in lat/long. Original layers found online such as climate, and topography are provided as links below.

The following data are provided:
logB.tif - a binary layer of logging presence/absence
logTS.tif - the time since logging (number of years from 2022)
wind.tif - the disturbance exposure map of wind throw events. Values represent the relative probability of being disturbed.
slide.tif - the disturbance exposure map of landslide events. Values represent the relative probability of being disturbed.
