8. Data Disclaimers 


Data Accuracy. NatureServe makes no warranties or guarantees as to the accuracy of the data; this applies to spatial accuracy, species identification, and other qualitative and quantitative attributes.  


Data Limitations. Data on invasive species for many areas have not been collected and/or submitted to iMapInvasives. Lack of data for a specific location does not mean that invasive species are absent from that location. The dataset should not be relied on as a definitive statement of the presence or absence of all invasive species at a given location and should not be substituted for on-site surveys. 

Data Purposes. The dataset is not intended to be used for regulatory or permitting purposes, nor for commercial purposes. It is intended for informational and educational purposes only, and to assist in natural resource management, land management, conservation planning, and biological and ecological research. 

Data Currency. The dataset contains only those records entered into iMapInvasives as of the date the dataset was accessed. The iMapInvasives database is continually growing as new records of invasive species are entered.  

Data Precision. Data entered into iMapInvasives comes from a wide variety of partners and Contributors, and has been collected and recorded with a wide variety of methods, tools, and formats. Therefore, the data in the dataset exhibits a wide range of spatial scales and precision.
