Field data for the Vegetation Mapping Inventory Project of Amistad National Recreation Area
2010-2019. Field data for the Vegetation Mapping Inventory Project of Amistad National Recreation Area
This reference is an assemblage of field data collected as part the baseline vegetation inventory for the park unit. Typical files here are vegetation plot data, accuracy assessment data, field photos, PDF showing locations of vegetation plots and accuracy assessment data, and other data for this type. In 2012, ecologists affiliated with the Lady Bird Johnson Wildflower Center (LBJWC) used the sampling plan to collect field data at 100 classification plot and two observation point locations. Field data was then entered into the NVIP-specific PLOTS database and reviewed by CHDN staff. In phase three, CTI analyzed the PLOTS data to classify 31 plant associations using the revised U.S. National Vegetation Classification (rUSNVC) standard. During phase four, CTI created 50 map units (37 vegetated and 13 land-use/land-cover types) to produce a detailed digital vegetation map layer. Phase five was the accuracy assessment (AA), where LBJWC field crews collected data at 562 AA points that were stratified by map class and randomly placed throughout the project area.
