Parramore Island of the Virginia Coast Reserve Permanent Plot Resurvey: Tree notes 1996
First 3-5 year resurvey of permanent monitoring plots using essentially the same protocol as the intial survey of 1992-1993 except that: 1.) standing biomass of the herbaceous groundcover was added (including for new lower salt marsh plots) using clip plots at the subplot locations; and 2.) an estimate of landcover/habitat class aggregation was conducted surrounding each plot center out to 60m in the four cardinal directions. Extends baseline data useful for estimating landscape-scale vegetative productivity, mortality, and turnover; for establishing pre-disturbance conditions in the case of later stand- or island-wide disturbance; and for assisting in the ground-truthing of landcover and habitat classification using aerial or satellite remote-sensing imagry.
Parramore Island of the Virginia Coast Reserve Permanent Plot Resurvey: Tree data 1997
This dataset includes both the original 1993 and the resurveyed 1996 data. It includes a number of corrections to the original data, and as such it SUPPLANTS and should be used in place of the older "VCR97011 : Tree Data" dataset.
Settlement Trees, Indiana Level 0, 1799-1847
We provide a Level 0 record of trees in Indiana transcribed from Public Land Surveys conducted by surveyors from the General Land Office of the United States in the 1800s. Posts were set every half mile in townships that were typically 6 miles by 6 miles square. Surveyors recorded details about the one to four trees closest (but typically recorded information for the two closest trees) to the posts and included information about the tree name (taxonomic specificity ranged by surveyor), tree diameter (inches), and distance and bearing from the post. Our records include the tree information and the location of the posts from which the tree information came from. For the msb-paleon.27.0 package, these Level 0 tree data were aggregated to the 8km grid resolution Level 1 product (see msb-paleon.26 package). That product was then statistically smoothed using a statistical model that accounts for zero-inflated continuous data with smoothing based on generalized additive modeling techniques and approximate Bayesian uncertainty estimates for the Level 2 products estimating aboveground biomass (msb-paleon.23), density (msb-paleon.24), and basal area (msb-paleon.25). The data processing steps and associated code are available in the GitHub repository: https://github.com/PalEON-Project/PLS_products. These products are used in the manucript, Paciorek et al., 2021, The forests of the midwestern United States at Euro-American settlement: spatial and physical structure based on contemporaneous survey data. PLoS ONE 16(2):e0246473 (https://doi.org/10.1371/journal.pone.0246473). This material is based upon work supported by the National Science Foundation under grants #DEB-2213579 and 1241874.

Dublin Trees GIS Database
<p><strong>Overview</strong></p> <p>This dataset on trees covers Dublin City, Ireland. It indicates the locations of over 300,000 trees which were acquired using a point-and-click methodology using a high-quality aerial image (resolution of 12.5 cm) taken in June 2018. Each x,y location represents the tree canopy centre. The database also includes the estimated height of these trees based on a Digital Elevation Model (horizontal resolution of 1m, vertical resolution *m). This information is complemented with detailed information on individual trees, where available. This includes, for example, data on 2440 street trees (species and dimensions) gathered in 2008/2009. The dataset will be updated at regular intervals as information on individual trees is acquired.</p> <p><em>* to be updated</em></p> <p> </p> <p><strong>Purpose</strong></p> <p>Information on trees (location, species, age, and health) in urban areas is needed to assess the green infrastructure and the ecosystem, environmental and social services that they provide. These data were acquired to support greening strategies and actions in the Dublin City Council area.</p> <p> </p> <p><em>Additional comments</em></p> <p>The creation of the Dublin tree database was supported in part by a research grant from Ireland’s Environmental Protection Agency (EPA) and using databases acquired by the School of Geography at UCD. The tree database is part of the <a href="https://mappinggreendublin.com/">Mapping Green Dublin</a> project and is being used by the <a href="https://www.curio.xyz/about">Curio app</a>, which allows citizens to add data on individual trees.</p>
