title: Data from: dammed ponds! a study of post-fire sediment and carbon dynamics in beaver ponds and their contributions to watershed resilience

description: Beaver ponds were surveyed as part of an effort to quantify post-fire
 sediment dynamics in beaver ponds. Forty-eight beaver ponds in the
 northern Colorado Rocky Mountains were surveyed between June and August,
 2022. We quantified the current and remaining sediment storage capacities
 within ponds with sediment depth surveys, and we calculated sedimentation
 rates by analyzing stratigraphy within pond sediment cores.

 Publishing.  A summary of the tabular datasets is given below. \# Beaver pond sedimentation rates, northern Colorado Rocky Mountains, 2022 Sediment cores were collected from beaver ponds as part of an effort to understand post-fire sediment dynamics in beaver ponds. About half the ponds sampled were in areas that burned in 2020 wildfires. We collected a total of 78 cores and from these we calculated three separate sedimentation rates. The first, total sedimentation, describes the average rate of sediment accumulation since pond construction. The mean rate was used in analysis for ponds with more than one core. The second, post-fire sedimentation rate, describes the rate of sediment accumulation in the two years after wildfire. Finally, pre-fire sedimentation rates describe the rate of sediment accumulation before wildfire. \## Description of the data and file structure Entity and Attribute Information: Detailed Description: Entity Type: Entity Type Label: beaver_pond_sedimentation_rates.csv Entity Type Definition: Comma Separated Value (CSV) file containing data.

About half the ponds were burned in 2020 wildfires. Ponds also varied in age, beaver activity, and location in relation to the channel and other ponds. \ The water and sediment depths in the ponds were surveyed along transects. The transect points were interpolated to produce an estimate of total water and sediment storage within each pond. Sedimentation rates calculated from sediment cores were averaged to produce pond sedimentation rates. \## Description of the data and file structure Entity and Attribute Information: Detailed Description: Entity Type: Entity Type Label: beaver_pond_sediment_water_volumes.csv Entity Type Definition: Comma Separated Value (CSV) file containing data.

Cores were collected from beaver ponds in the northern Colorado Rocky Mountains that were surveyed between June and August 2022. About half the ponds were burned in 2020 wildfires. Ponds also varied in age, beaver activity, and location in relation to the channel and other ponds. We identified beaver ponds from aerial imagery, sites of previous research, and local knowledge. Typically, two cores were collected from each pond. We delineated stratigraphic units by color, texture, and grain size. We examined a sample of each stratigraphic unit under a dissecting microscope to identify charcoal and determine the proportion of the sediment constituents. \## Description of the data and file structure Entity and Attribute Information: Detailed Description: Entity Type: Entity Type Label: beaver_pond_sediment_core_descriptions_2022.csv Entity Type Definition: Comma Separated Value (CSV) file containing data.
