Title Plant species by site matrix
Downloaded 6 times
Description This file contains the matrix of species abundances across sites used to conduct all analyses. The column "LOT" refers to the individual vacant lot, "TYPE" refers to whether the surveyed area was present in the building footprint section (BF) or remnant garden section (RG), and the remaining columns all refer to observed species (or genera) observed at each site, with estimates of their percentage cover.

Title VacantLots_DemolitionDate
Downloaded 4 times
Description This file continues the estimated year of demolition for the vacant lots. Column "Code" refers to the id number which links the demolition date to the species x site matrix, "Address" is the street address in Baltimore, MD, USA where the vacant lot resides, "Source" refers to whether the date of demolition was estimated from demolition records from the Baltimore City Archives or from high resolution aerial photographs, "Demolition date" is the year in which the vacant lot was created, and "TimeSinceDemolition" are the number of years between demolition and when vegetation was surveyed (2012).

Title Species_x_TraitsMatrix
Downloaded 10 times
Description Matrix of functional traits collected for all the species surveyed within the vacant lots. Traits which are categorical (presence/absence) are indicated with 1/0 designations. For continuous traits, terminal velocity is measured in m/sec, specific leaf area (SLA) is in m, Height is in m and seed mass is in g/1000 seeds. Sources for each trait are described within the accompanying paper, in Table 1. Missing data is indicated with by "NA".

Title Community weighted means of functional traits
Downloaded 3 times
Description A .csv file containing the community weighted trait means of each building footprint and remnant garden community surveyed. Continuous trait means represent the mean value of the species present in that community, weighted by abundance. Categorical trait means are all binary (presence/absence) and represent the proportional abundance of the species possessing each trait in the community.

Title RawSoilData
Downloaded 4 times
Description A .csv file containing raw soil results for a subset of sites surveyed. Organic matter is reported as %, and all other soil nutrients' units are in mg/kg. For more detailed information on the methodology for collecting and analyzing soil samples, please see: Johnson, AL, Tauzer EC, and Swan, CM. (2015).
