This paper presents an analysis of two conservation aspects related to the risk of degradation of several dinosaur ichnite sites in La Rioja, namely fragility and natural vulnerability. Although the sites studied are classified into a number of different categories, most of them present a similar medium to high degree of fragility. Natural vulnerability, which is occasionally high, is due both to low-impact geological factors, mainly water and gravity, and biological factors, mainly vegetation. Both the fragility and the natural vulnerability of these sites, many of which present significant degradation on a human time scale, must be taken into account in the management of this geological heritage.
