Hi Mariana: If I understand you well, you need to create a new field, making an expresssion in field calculator, something as:
case when conservative>=1 and conservative<4 then 1 when conservative>=4 and conservartive<32 then 0 end After that, you can try intersection... or union. What about to work as raster?
