Is there a way to calculate the distance between points and contour lines with a minimum elevation value ?

Context: I have data from vegetation plots in island that is mostly flat, with the exception of the sand dunes close to the shores. I need to know which plots are located closer to a dune (thus more "sheltered") and each ones are distant. My plots are points and the contour lines were extracted from a DGM of resolution 1m.

Either select all contour lines above your specified threshold, or create polygons representing the dunes, then run join by nearest with the plots as first input and the selected lines/dune-polygons as second input. All attributes of the nearest line/dune will be added to the plots, including a distance.
