Title Soil Sample Data with 4 Site Codes
Downloaded 7 times
Description Soil Sample Data documentation. 137 records, each representing a point at which soil samples were obtained. Variables are "SITECODE", "SITENUM", "TDIST" (m), "X" (m), "Y" (m), "EL.CA.MOL" (mol/m2), "EL.MG.MOL" (mol/m2), "EL.K.MOL" (mol/m2), "EX.CA.MOL" (mol/m2), "EX.MG.MOL" (mol/m2), "EX.K.MOL" (mol/m2) "SITECODE", values 1-4, is code indicating area of landscape where samples were taken. In the accompanying manuscript, corresponding locations and codes are 1=Camps Pond (A), 2=Wangum (D), 3 = #4 Trail (B), 4 = Backgate (C). "SITENUM", values 1-104 (not inclusive). SITENUM 1-18 and 52-95 are at Camps Pond. SITENUM 19-30 are at Wangum, SITENUM 31-36 are at #4 Trail. SITENUM 101 is at Backgate, and SITENUM 104 is at #4 Trail. "TDIST" indicates distance along transect, in meters. SITENUM 101 consists of two parallel transects: the first transect has distances from 0-100, and second, from 200-300 (i.e., the different transect is indicated by adding 200 to each distance along it). SITENUM 104 consists of a single 200 m transect with soil sample sites at 5 m intervals. Every record is defined by a unique combination of "SITENUM" and "TDIST". "X" and "Y" are xy coordinates (in m) where soil sample was taken. There is a unique XY coordinate reference system at each value of "SITENUM". "EL.CA.MOL" (mol/m2), "EL.MG.MOL" (mol/m2), "EL.K.MOL" (mol/m2), "EX.CA.MOL" (mol/m2), "EX.MG.MOL" (mol/m2), "EX.K.MOL" (mol/m2) are values of exchangeable calcium, magnesium and potassium.

Title Tree Map Data Checked 2015
Downloaded 4 times
Description The file "Tree Map Data Checked 2015.txt" provides tree map data for plots where soil samples were taken. Variables are "SITENUM", "X" (m), "Y" (m), "Z" (m), "DBH" (cm), and "SPECIES". It has original site numbers (not grouped into 4 sites, and not numbered consecutively). 1:18 - Camps Pond 19:30 - Wangum 31:36 - #4 Trail 51-98: Sites originally sampled by Feike Dijkstra, n=18, all at Camps Pond 104: Transect #1 at #4 Trail 101: “Back Gate” transects #1 and #2 X, Y, and Z are local tree-location coordinates. Each SITENUM has a common coordinate reference system. DBH is tree's breast-height diameter. SPECIES is a four-letter acronym that is a concatentation of the first two letters of the genus and species. Acronyms and associated species are given below "species","binomial" "acpe","Acer pennsylvanica" "acru","Acer rubrum" "acsa","Acer saccharum" "beal","Betula alleghaniensis" "bepa","Betula papyrifera" "bepo","Betula populifolia" "crb","Crataegus brainerdii" "caca","Carpinus caroliniana" "caov","Carya ovata" "fram","Fraxinus americana" "fagr","Fagus grandifolia" "havi","Hammamelis virginiana" "masy","Malus sylvestris" "osvi","Ostrya virginiana" "pran","Prunus angustifolia" "pprr","Picea rubens "prse","Prunus serotina" "pist","Pinus strobus" "qual","Quercus alba" "quru","Quercus rubra" "tsca","Tsuga canadensis"
