System, methods, and other embodiments described herein relate to identifying changes within a surrounding environment of a vehicle. In one embodiment, a method includes collecting, using at least one sensor of the vehicle, sensor data about the surrounding environment. The method includes analyzing the sensor data to identify features of the surrounding environment. The features are landmarks of the surrounding environment that are indicated within a map of the surrounding environment. The sensor data indicates at least measurements associated with the features as acquired by the at least one sensor. The method includes computing persistence likelihoods for the features according to a persistence model that characterizes at least prior observations of the features and relationships between the features. The persistence likelihoods indicate estimated persistences of the features to indicate whether the features likely still exist. The method includes controlling the vehicle according to the persistence likelihoods.
