Title: BLM REA CYR 2013 5th level hydrologic units currently infested but misclassified as not infested
Description:
Abstract: Survey intensity for non-native plant infestations in the Central Yukon area are not strong or consistent; we therefore developed an analytical model to identify areas that are perceived to be currently vulnerable to invasion by non-native plant species. This analysis is intended to supplement the empirical data, identify areas in which future surveys may be directed, and evaluate the potential change in vulnerability in the future. The analytical approach used here (variance partitioning via classification and regression tree) facilitates the evaluation of a large number of variables that may have non-linear relationships and complex interactions. This approach has been used elsewhere to understand patterns of plant invasion vulnerabilities. The purpose of this dataset is to identify misclassified watersheds in the classification and regression tree analysis. Misclassified watersheds were those watersheds that are actually infested but the classification and regression tree analysis predicted incorrectly as low infestation vulnerability.
Purpose: This dataset was developed as part of thesis work in pursuit of a Masters Degree by Megumi Aisu and represents misclassification of the infestation of 5th level hydrologic units by non-native plant species. This version of the dataset has been clipped to the Central Yukon study area.
Supplemental Information: The misclassified watersheds were produced using variance partitioning through classification and regression tree models.

Use Constraints: These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions. The User assumes the entire risk associated with its use of these data and bears all responsibility in determining whether these data are fit for the User's intended use. The information contained in these data is dynamic and may change over time. The data are not better than the original sources from which they were derived, and both scale and accuracy may vary across the data set. These data may not have the accuracy, resolution, completeness, timeliness, or other characteristics appropriate for applications that potential users of the data may contemplate. The User is encouraged to carefully consider the content of the metadata file associated with these data. These data are neither legal documents nor land surveys, and must not be used as such. Official records may be referenced at most BLM offices. Please report any errors in the data to the BLM office for which it was obtained. The BLM should be cited as the data source in any products derived from these data. Any Users wishing to modify the data should describe the types of modifications they have performed. The User should not misrepresent the data, nor imply that changes made were approved or endorsed by BLM. This information may be updated without notification.

Data Quality Information:
Attribute Value Accuracy Information:
Attribute Accuracy Report: All misclassified watersheds attributes are modeled and therefore are not exact representations of actual conditions. Attributes should be viewed as approximations at the landscape level. The accuracy of infestation vulnerability is a derivative of the accuracy of source datasets, which represent the best available regionally comprehensive datasets in 2013.
Logical Consistency Report: Peer review was performed to ensure data accuracy and completeness. Basic checks were performed to ensure integrity and consistency.
Completeness Report: The modeled infestation vulnerability datasets are complete. There are no future plans for updates.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report: The horizontal positioning of attributes is based on the Watershed Boundaries Dataset developed by USGS. No errors were identified in horizontal positioning of features.
Positional Accuracy:
Vertical Positional Accuracy:
Vertical Positional Accuracy Report: This dataset does not include a vertical component.
