Zonal Statistics involving a raster and a polygon layer

[MirceaRau]

I have a raster 2mx2m with height values for forest canopy and a polygon layer stratifying the type of stand.
I would like to calculate the average height value for each polygon and wright the value in the attribute table of the polygon.
I tried zonal statistics - spatial analyst and zonal statistics as table and the computer crashed.

Zonal statistics as Table is the appropriate tool.
Is your dataset extremly large?
Does your polygon layer have many classes that you are evaluating?
When does it crash, and what is the error message generated in the Geoprocessing Results window?

You could try limiting the analysis to a single polygon class, and see if that works.
Best Regards,
