Grasslands are areas of undeveloped land in the Austin ETJ where the dominant vegetation consists of sizeable communities of predominantly native grasses. The purpose of this feature class is to track the preservation of grassland or prairie areas. These grasslands were digitized from construction plans, environmental assessments, and City of Austin staff field observations into a versioned SDE database using ArcMap. Actual areas for any particular feature may be fluctuate due to antecedent rainfall, subsequent development activity or the invasion of woody species, Grasslands are not, at the time of this writing, a protected Critical Environmental Feature.
