Physical environment of the Luquillo Forest Dynamics Plot (LFDP), Puerto Rico

General Information
Data Package:
Local Identifier:knb-lter-luq.47.381078
Title:Physical environment of the Luquillo Forest Dynamics Plot (LFDP), Puerto Rico
Alternate Identifier:DOI PLACE HOLDER
Abstract:

This file contains data that describe the physical and environmental attributes of the LFDP. The attributes include elevation, topography type, and percentage slope. All data are given for the 20 m by 20 m quadrat scale. Information on soils are taken form an interpolation of the soil map produced by the Natural Resources Conservation Service, US Department of Agriculture (Soil Survey 1995). Other information from the elevation of each of the corner posts defining the quadrats.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.

The soil survey gave 23 different categories based on a combination of three separate codes. In the soil survey book these are represented by number; letter; number. We have converted this to number; number; number for ease of analysis. See Variables Sscode soil; sscode %slope and Sscode rock below for a definition for each of the three numbers in the code.Soil survey gave 23 different codes for soil classification but on the 20 x 20 m quadrat scale there are only 22 different categories at this scale.Code for soil type as determined by the Soil Survey (see refs).

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.

General Data Use Agreement

Where appropriate, the Data User is encouraged to consider collaboration or coauthorship with the authors. The Data User should realize that misinterpretation of data may occur if used out of context of the original study. While substantial efforts are made to ensure the accuracy of data and associated documentation, complete accuracy of data sets cannot be guaranteed. All data are made available “as is.” The Data User should be aware, however, that data are updated periodically and it is the responsibility of the Data User to check for new versions of the data.

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

Plot number, quadrat, column and row, describe the position of each 20 x 20 m quadrat within the grid structure of the 16 ha plot. The quadrat naming convention is described in the variable list and is the same as in Condit (1998). Xm and Ym are the distance east (X) and north (Y) respectively measured in meters from the southwest corner of the 16 ha plot to the southwest corner of each quadrat. Exposure class is based upon aspect, and was classified by the exposure of each quadrat to primarily NE winds. NE = 4, E and N = 3, NW and SE = 2, W and S = 1, SW = 0 Topographic class - topographic exposure class 1 - valley, 2 - bench (a slope of < 15%), 3 - slope (>= 15%), 4 - ridge. These were derived from the digital elevation model and were not ground truthed. Canopy cover class was classified into 4 types based upon the percentage canopy cover seen in aerial photographs of the plot area taken in 1936. Marchterre Fluet did the analysis of the aerial photographs, taken in 1936, at Harvard University
