Brennan, T.J. Keeley, J.E. 20210111 Digital Tabular Data (CSV) Denver, CO U.S. Geological Survey data release https://doi.org/10.5066/F73776V9 Teresa J. Brennan Jon E. Keeley 2017 publication Fire Ecology vol. 13 N/A SpringerLink https://doi.org/10.4996/fireecology.130312013 The sampling design at each of the 149 mechanically masticated fuel treatment study sites consisted of a 10 x 100 m plot established within the treated area at the random point generated in ArcGIS and an adjacent 10 x 100 m control plot placed one meter inside the edge of untreated vegetation to avoid edge affects. Each study plot was further subdivided into 10 100-m2 subplots with a nested 1-m2 quadrat placed along the top edge of the measurement tape. Postfire study sites consisted of a 20 x 50 m plot that was equal in area to a fuel treatment study plot and was also further subdivided into 10 100-m2 subplots with a nested 1-m2 quadrat placed along the outer top and bottom edges of the plot. Cover and density were recorded for each species within 1-m2 quadrats and a list of additional species present within the rest of the 100-m2 subplot was compiled. Ocular estimates of cover were made and density was either counted, or estimated when there were more than 30 individuals in a quadrat. First year seedlings were recorded separately from mature and resprouting individuals. Comprehensive surveys for additional species were conducted in subplots of mechanical treatments and postfire plots; whereas controls were more limited and as such total species richness in these plots was potentially underrepresented. The data were collected with the purpose of analyzing the response and recovery of chaparral vegetation to mastication fuel treatments. Chaparral communities are examined in this project with all individual species identified. Baldwin BG, Goldman DH, Keil DJ, Patterson R, Rosatti TJ, Wilken DH, editors. 2012.

Field assistance from Chelsea Morgan (Crew lead), Callen Huff, Anthony Baniaga, Warren Reed, Grayden Dill, and Richard Mansfield. Environment as of Metadata Creation: Microsoft Windows 7 Version 6.1 (Build 7601) Service Pack 1; Esri ArcGIS 10.2.2 (Build 3552) Service Pack N/A (Build N/A) Data were spot checked in the field as well as after data entry. Data entry forms in Access 2010 were used to help eliminate data entry errors. Outliers were identified and analyzed to determine their accuracy. No formal logical accuracy tests were conducted. Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. A formal accuracy assessment of the vertical positional information in the data set has either not been conducted, or is not applicable. The sampling design at each study site consisted of a 10 x 100 m plot within the treated area and an adjacent 100 m control transect placed one meter inside the edge of untreated vegetation. Treatment plots were further subdivided into 10 100-m squared subplots with a nested 1-m squared quadrat in the upper left corner of each. Cover and density was recorded for each species within quadrats and a list of additional species present within the rest of the 100-m squared subplot was compiled. Ocular estimates of cover were made and density was either counted, or when there were more than 30 individuals in a quadrat, estimated. Seedlings and mature plants were recorded separately. Stand height in treatments was determined by recording the height of the first live woody species encountered along each 10 m subplot. Species composition in controls was determined by recording the cover and density of individual species in 1-m squared quadrats every 10 m along the transect using the methods described for treatments. An additional 2-m squared quadrat was placed adjacent to each 1-m squared along the control transect from which the height and cover of each woody species was recorded. Pre-treatment stand age was obtained from stem samples collected from two obligate-seeding individuals in the untreated controls.
