Title:Tree Map for Census at the Luquillo Forest Dynamics Plot (LFDP), Puerto Rico
Alternate Identifier:DOI PLACE HOLDER
Abstract:

This data set shows the Tag number, Quadrat location, Species code, diameter and XY coordinates of stems >=10 cm D130 present at the time of Hurricane Hugo and in the first census. The data set is composed of two files both with the same file structure. In LFDP_C1treemap.txt the diameters (Fdiam) are as recorded in the field data. In LFDP_C1TREEMAPa.txt the stem diameters (Fdiam) were calculated to allocate "missed" stems (stems >=10 cm D130) that were found in survey 2, 3 or Census 2 to Census 1 survey 1. We calculated the diameter the stem would have had, if it had been recorded at the same time the quadrat it was located in was assessed, in the appropriate survey for that stem size. 

To extrapolate the stem size back in time, we used the actual growth rate of that individual stem if more than one measurement was available. If only one diameter measurement was available we used the median growth rate for that species in the appropriate size class stems >=10, <30 cm D130). In our publications we will combine data sets LFDP_C1treemap.txt and LFDP_C1TREEMAPa.txt to make Census 1 and to reconstruct the forest for stems >= 10 cm D130 at the time of Hurricane Hugo. We have divided the data into two separate files to ensure that when stem diameters are compared to future censuses the diameter data in LFDP_C1TREEMAPa.txt are not used to calculate growth rates. The last corrections to the Census 1 data were made in May 2001. The National Science Foundation requires that data from projects it funds are posted on the web two years after any data set has been organized and "cleaned". The data from each census of the LFDP will be updated at intervals as each survey of the LFDP shows errors in the previous data collection. After posting on the web, researchers who are not part of the project are then welcome to use the data. Given the enormous amount of time, effort and resources required to manage the LFDP, obtain these data, and ensure data accuracy, LFDP Principal Investigators request that researchers intending to use this data comply with the requests below. Through complying with these requests we can ensure that the data are interpreted correctly, analyses are not repeated unnecessarily, beneficial collaboration between users is promoted and the Principle Investigators investment in this project is protected. Submit to the LFDP PIs a short (1 page) description of how you intend to use the data; · Invite LFDP PIs to be co-authors on any publication that uses the data in a substantial way (some PIs may decline and other LFDP scientists may need to be included); If the LFDP PIs are not co-authors, send the PIs a draft of any paper using LFDP data, so that the PIs may comment upon it; In the methods section of any publication using LFDP data, describe that data as coming from the "Luquillo Forest Dynamics Plot, part of the Luquillo Experimental Forest Long-Term Ecological Research Program"; Acknowledge in any publication using LFDP data the "The Luquillo Experimental Forest Long-Term Ecological Research Program, supported by the U.S. National Science Foundation, the University of Puerto Rico, and the International Institute of Tropical Forestry"; · Supply the LFDP PIs with 10 reprints of any publication using LFDP data. · Accept that the LFDP PIs can not guarantee that the LFDP data you intend to use, has not already been submitted for publication or published.

Data Policies

LTER Network Data Access Policy, Data Access Requirements, and General Data Use Agreement
approved by the LTER Coordinating Committee April 6, 2005

Long Term Ecological Research Network Data Access Policy

The LTER data policy includes three specific sections designed to express shared network policies regarding the release of LTER data products, user registration for accessing data, and the licensing agreements specifying the conditions for data use.

LTER Network Data Release Policy

Data and information derived from publicly funded research in the U.S. LTER Network, totally or partially from LTER funds from NSF, Institutional Cost-Share, or Partner Agency or Institution where a formal memorandum of understanding with LTER has been established, are made available online with as few restrictions as possible, on a nondiscriminatory basis. LTER Network scientists should make every effort to release data in a timely fashion and with attention to accurate and complete metadata.

Data[current-user:created]

There are two data types:

Type I – data are to be released to the general public according to the terms of the general data use agreement (see Section 3 below) within 2 years from collection and no later than the publication of the main findings from the dataset and,

Type II - data are to be released to restricted audiences according to terms specified by the owners of the data. Type II data are considered to be exceptional and should be rare in occurrence. The justification for exceptions must be well documented and approved by the lead PI and Site Data Manager. Some examples of Type II data restrictions may include: locations of rare or endangered species, data that are covered under prior licensing or copyright (e.g., SPOT satellite data), or covered by the Human Subjects Act. Researchers that make use of Type II Data may be subject to additional restrictions to protect any applicable commercial or confidentiality interests.

While the spirit of this document is to promote maximum availability for ecological data in either Type I or II status, there are criteria by which priority for data release may be determined. Primary observations collected for core research activities directly supported by LTER research must receive the highest priority for data release. Data collected by other sources to which LTER supported research has added value is also a high priority Other types of data including non-LTER data that was acquired for LTER research, student thesis data, schoolyard LTER data, or legacy data that already suffer from inadequate documentation or format obsolescence may be ranked a lower priority by a site with justifications provided in their data management policy. Finally, some data may be determined of lowest priority for archiving on the grounds that they are interim data that led to final products that carry the scientific value. These might include data files created during stages within an analytic workflow, raw or replicate data values that were subsequently aggregated or processed for release, or individual outputs from stochastic models.

Metadata

Metadata documenting archived/online data sets of all types listed above will be made available when, or before, the dataset itself is released according to the terms above.
All metadata will be publicly available regardless of any restrictions on access to the data.
All metadata will follow LTER recommended standards and will minimally contain adequate information on proper citation, access, contact information, and discovery. Complete information including methods, structure, semantics, and quality control/assurance is expected for most datasets and is strongly encouraged.
LTER Network Data Access Requirements

The access to all LTER data is subject to requirements set forth by this policy document to enable data providers to track usage, evaluate its impact in the community, and confirm users' acceptance of the terms of acceptable use. These requirements are standardized across the LTER Network to provide contractual exchange of data between Site Data Providers, Network Data Providers, and Data Users that can be encoded into electronic form and exchanged between computers. This will allow direct access to data via a common portal once these requirements have been fulfilled. The following information may be required directly or by proxy prior to the transference of any data object:

Registration

1. Name

2. Affiliation

3. Email Address

4. Full Contact Information

Acceptance of the General Public Use Agreement or Restricted Data Use Agreement, as applicable.
A Statement of Intended Use that is compliant with the above agreements. Such statements may be made submitted explicitly or made implicitly via the data access portal interface.

Methods and protocols used in the collection of this data package
Description:

During Census 1 survey 1, and Census 2, all stems >=10 cm D130 were marked on a map of the 20 x 20 m quadrat in which they were located. We aimed for an accuracy of about 0.5 m. After the maps were complete the location of the stems relative to the Southwest corner of the LFDP was recorded using a map digitizer. This gave the X Y coordinates of each tree in meters from the origin at the Southwest corner of the LFDP. Unfortunately stems >=10 cm D130 that were encountered in Census 1 surveys 2 and 3 were not located on a map so it wasn't until Census 2 that the XY coordinates could be determined. As a result some of the stems representing Census 1 have no X Y coordinates as they had died and disappeared before their location was established. In these cases we know only which quadrat and subquadrat the stem was located in.
